Diamondbacks Not Close To Any Pitching Trades

By | at

The Diamondbacks’ surprise signing of Corbin Burnes added a new frontline arm to a rotation that was already operating at a surplus on paper.  Burnes joins Zac Gallen, Merrill Kelly, Eduardo Rodriguez, Jordan Montgomery, Brandon Pfaadt, and Ryne Nelson, giving the Snakes an enviably deep group of starting pitchers.  The D’backs had already been drawing trade interest in this group even before Burnes was added, but Nick Piecoro of the Arizona Republic sports that the Burnes signing wasn’t made with any other pitching swaps immediately on the horizon.

According to Piecoro, no “other deals [are] lined up or even close” involving Arizona’s pitchers, as the Diamondbacks will continue to take a measured view of the market.  A source tells Piecoro that the D’Backs will likely “spend the coming days fielding calls from teams still in the hunt for starters, including those that were in on Burnes.”  The D’Backs aren’t in any particular rush to complete a trade any time soon, as having more than a full rotation in place before New Year’s Eve gives the club plenty of time to figure out the best possible offer.

It also isn’t entirely out of the question that the Diamondbacks stand pat on their starters, especially if an injury emerges to a starter during their offseason training, or during Spring Training.  Kelly, Rodriguez, and Montgomery all missed significant time with injuries last season, so there is obvious value in having extra pitchers on hand should any more health issues create openings in the rotation.  Operating with a six-man rotation is also a possibility, in order to keep everyone healthy and fresh for what the D’Backs hope can be an extended run through the playoffs.

Given how the Burnes deal reportedly came together just within the last week when Burnes himself approached the D’Backs, it isn’t surprising that the signing wasn’t part of an immediate plan to re-model the pitching staff.  Such two-step transactions are usually hard to pull off, though the Diamondbacks were part of such a set of moves from the Guardians just last week — Arizona acquired Josh Naylor from the Guards, and Cleveland then signed Carlos Santana that same day to immediately fill Naylor’s spot as the everyday first baseman.

The fact that Burnes signed with a team that was seemingly already set for starting pitching gives GM Mike Hazen even more leverage in shopping his hurlers.  Such known Burnes suitors like the Orioles, Blue Jays, or Giants are still in need of pitching, to say nothing of the many other starter-needy clubs on the market that weren’t willing or able to meet Burnes’ asking price.

Nothing seems to have changed in terms of which starters are most prominently on Arizona’s trade block.  Gallen and Kelly are both free agents next winter but don’t seem likely to be dealt, as a team source told Piecoro that the team’s focus in on “trying to put the best team on the field in 2025.”  Nelson is controlled through the 2027 season and Pfaadt through the 2029 season, so the Diamondbacks would probably only move either if a longer-term asset (likely a position player) could be obtained in return.  The D’Backs might not mind moving the $66MM remaining on Rodriguez’s contract, but the club would certainly have to sell low and eat some of that money in the wake of E-Rod’s injury-plagued down year.

That leaves Montgomery as still the chief candidate to be dealt before Opening Day.  Montgomery’s trade value is also at a low ebb after his rough first year in Arizona, and his $22.5MM salary for the 2025 season.  Owner Ken Kendrick’s public criticism of Montgomery following the season only increased the probability that the left-hander would be pitching elsewhere next year, yet again, the Burnes signing gives the D’Backs some flexibility in this regard.  The Diamondbacks technically don’t have to trade Montgomery if an acceptable offer for another starter comes their way, and offers for Montgomery might improve if other teams become increasingly desperate to add pitching.

Diamondbacks’ Starters Drawing Trade Interest

By | at

As free agent starters begin to find new homes — Blake Snell, Yusei Kikuchi, Frankie Montas, Matthew Boyd and Kyle Hendricks have all signed in the past two weeks — interest in the Diamondbacks’ collection of rotation arms has “started to pick up,” general manager Mike Hazen tells Nick Piecoro of the Arizona Republic. The D-backs have at least six starters on the roster at present: Zac Gallen, Merrill Kelly, Eduardo Rodriguez, Brandon Pfaadt, Ryne Nelson and Jordan Montgomery.

Of the six, Montgomery is the most obvious trade candidate, following a rough 2024 showing and owner Ken Kendrick’s public, verbal thrashing of the player. In October, Kendrick openly lamented ever pushing his front office to sign Montgomery late in the 2023-24 offseason, calling it a “horrible decision to have invested that money in a guy that performed as poorly as he did” and “our biggest mistake this season from a talent standpoint.” Montgomery unsurprisingly exercised a $22.5MM player option even after being called out by Kendrick — a straightforward decision for a pitcher coming off an injury-shortened year with career-worst marks in ERA (6.23), strikeout rate (15.6%) and walk rate (8.3%).

For all the focus placed on Montgomery’s struggles last year, the other veteran lefty signed by Arizona last offseason also fell well short of expectations. Rodriguez signed a four-year, $80MM pact with the Snakes but was limited to just 10 starts after opening the season on the injured list due to a shoulder strain. He pitched 50 innings of 5.04 ERA ball while showing diminished life on his four-seamer and sinker. Rodriguez is owed $20MM for the coming season, $21MM in 2026 and $19MM in 2027. He’s also guaranteed a $6MM buyout on a $17MM mutual option for the 2028 season — an option that could automatically vest based on his innings tallies in 2026-27. While Montgomery’s contract is underwater, the three years and $66MM remaining on Rodriguez’s pact very likely make him even harder to unload.

Any of  the other four arms in Arizona’s rotation would be hard to pry loose. Ace Zac Gallen is a Cy Young contender when healthy, evidenced by fifth- and third-place finishes in 2022 and 2023 balloting. He missed about a month of action with a hamstring strain in 2024 and flashed worse command than usual (relative to his excellent standards, anyhow), but any team would love to have the right-hander. He’s projected by MLBTR contributor Matt Swartz to earn $14.1MM in his final season of club control before becoming a free agent next winter. Gallen is not being shopped, to be clear. Hazen even chuckled at the mere notion of Gallen being a prominent trade candidate in a mid-November appearance on Arizona Sports 98.7’s Wolf & Luke Show (2:35 mark). That’s unlikely to stop other teams from trying.

Kelly, like Gallen, is a free agent next offseason. He missed more than three months in 2024 with a shoulder strain but was generally effective when healthy, logging a 4.03 ERA with a slightly below-average 21% strikeout rate and a strong 6.3% walk rate. Arizona made an easy call to exercise a $7MM club option on Kelly for the upcoming season.

Nelson and Pfaadt are both controllable and thus quite valuable to the Snakes. The 26-year-old Nelson is under club control for four more seasons and just tossed 150 2/3 innings with a 4.24 ERA, 20% strikeout rate and outstanding 5.4% walk rate in 2024. Those numbers are skewed by a slow start, but from July onward, Nelson posted a 3.05 ERA, 24.8 K% and 5.0 BB% in 82 2/3 frames. He’s not yet eligible for arbitration.

Pfaadt, also 26, paced the D-backs with 181 2/3 innings and 32 starts. His 4.71 ERA doesn’t stand out, but his 24.3% strikeout rate, 5.5% walk rate, 3.61 FIP and 3.65 SIERA are all far more encouraging. He might’ve worn down a bit late in the season as he pushed through that new career-high workload, as his worst months were August and September. A disproportionate amount of the damage against Pfaadt this season came in one nightmare September outing, wherein the Brewers tagged him for eight runs in just 1 2/3 innings. Lopping off even that one start would cause his season-long ERA to drop by nearly 40 points. Regardless, the former top prospect is a 2025 breakout candidate when considering his pedigree and rate stats that far outpace his pedestrian earned run average. Of the arms on the big league staff, he’s probably the most difficult for another team to acquire.

There’s depth even beyond that sextet. Right-hander Drey Jameson will be back from 2023 Tommy John surgery next year. He’s already had some big league success. There are another five starters on the 40-man roster and likely ticketed for Triple-A, all of whom have minor league options remaining and at least a bit of MLB experience: Yilber Diaz, Slade Cecconi, Blake Walston, Cristian Mena and Tommy Henry. Few organizations boast a stockpile of arms so deep.

All of that is to say — it’s hardly a surprise that clubs are calling the D-backs about their starters. The same is true of their outfielders, as Hazen already acknowledged a couple weeks back. Piecoro writes that (naturally) Montgomery is both the likeliest to move and the pitcher whom the team would most strongly prefer to deal. Hazen stated that Kendrick’s comments regarding the left-hander have “zero” impact on the urgency to trade him, though there’s likely some public-facing lip service at play there.

Piecoro adds that the D-backs would be willing to take on another contract of some note in return for Montgomery (if said player filled a roster need) or perhaps pursue more of a traditional salary dump, where they shed as much of the contract as possible for little to no return. Of note, Hazen suggested that if he’s to ultimately move Montgomery in deal that is primarily rooted in salary relief, the trade would need to come together before the bulk of quality free agents come off the board: “At some point, it doesn’t make sense because your pivot moves are picking at the edges rather than getting somebody (who is more of a target).”

Diamondbacks Notes: Turner, Pitching, Hazen, Deadline

By | at

Justin Turner is “atop [the Diamondbacks’] wish list” this offseason, USA Today’s Bob Nightengale writes.  It isn’t any surprise that the D’Backs would be in pursuit of Turner, as the team also had interest in the veteran infielder last winter, and Turner’s stock is quite high after a successful year with the Red Sox.

Turner hit .276/.345/.455 with 23 homers over 626 plate appearances with Boston last season, as he hasn’t shown much sign of decline even though he turns 39 later this month.  He’s back on the free agent market after declining his player option to remain with the Sox, and seems likely to land another multi-year contract even at his advanced age.  Anything beyond two guaranteed years might be a bit of a reach, however, which perhaps keeps Turner within the Diamondbacks’ price range.

Several contenders or would-be contenders are likely to check in on Turner this winter, so the reigning NL champion D’Backs won’t be alone in their pursuit.  Playing in Phoenix would also bring Turner a bit closer to his home in Southern California, and if Turner had designs on being a regular third baseman again, the Diamondbacks have an opening at the hot corner since Evan Longoria is also a free agent.  Turner would probably be in the lineup most every day as either a third baseman, designated hitter, or occasional first baseman if Christian Walker is at DH or getting a rest day.  When Turner isn’t at third base, Gerardo Perdomo or Emmanuel Rivera would be on hand to man the position.

Signing Turner would also add a right-handed bat to Arizona’s lineup, and GM Mike Hazen told reporters (including The Athletic’s Evan Drellich and Nick Piecoro of the Arizona Republic) that keeping the lineup balanced is “probably going to be an area that we’re going to need to address again.”  Free agents Longoria, Lourdes Gurriel Jr., and Tommy Pham all hit from the right side, leaving the Snakes a little heavy on lefty swingers and switch-hitters.  Top prospect Jordan Lawlar is a right-handed hitter who is expected to get a larger role after making his MLB debut in 2023, though installing Lawlar as the everyday shortstop might be a little bold, and it might be dependent on how the D’Backs address the third base situation.

Beyond another hitter or two, Hazen stressed that his team will be looking to add some experienced rotation help.  Zac Gallen and Merrill Kelly were the cornerstones of an otherwise subpar rotation, as most of the younger arms had some growing pains, veteran Zach Davies was injured and mostly ineffective, and Madison Bumgarner was released entirely after continued struggles.

Rookie Brandon Pfaadt established himself during the playoffs, so he’ll be penciled into one spot along with Gallen and Kelly.  That leaves room for another seasoned pitcher within the rotation’s top four, and Hazen felt the Snakes were simply lacking in this department during the postseason, most notably in their now-infamous bullpen game in Game 4 of the World Series.

“Having veterans in that rotation matter.  I think you looked across the aisle here in this series and [the Rangers] had more veteran starting pitchers than we did,” Hazen said.

To this end, Hazen had some regrets over not already addressing this need last summer.  The general manager said he “chased every starting pitcher in the free market” at the deadline, and noted that teams often asked for Pfaadt and Alek Thomas in trade demands.  While Hazen had no intention of moving either of those players, “were there other avenues that we could have pushed, by adding more prospects in the deals where it didn’t include those guys?  Where I should have gone down that route?  I don’t know.  I don’t know the answer to those things.  But I know I didn’t get a starting pitcher.  And that’s on me.”

Big Hype Prospects: Rodriguez, Rodriguez, Harrison, Pfaadt, Ford

By | at

The NL Central remains a hotbed of prospect promotions. Henry Davis is the latest big name scheduled to make his debut. Out west, Emmet Sheehan appeared last Friday. Unless you’re a diehard Dodgers fan, chances are you first heard about Sheehan’s rising star during our AFL coverage last fall. Sheehan tossed six scoreless innings.

Five Big Hype Prospects

Grayson Rodriguez, 23, SP, BAL (AAA)
(AAA) 22 IP, 11.86 K/9, 4.91 BB/9, 2.86 ERA

Earlier in the season, Rodriguez posted a 7.35 ERA in 45 1/3 Major League innings. His is a cautionary tale about pitcher prospectdom. Like many pitchers who sustain a lat injury, he hasn’t returned at the top of his game. In particular, his offspeed stuff and command haven’t been as crisp post-injury. He still profiles as a high-quality starter. There’s less certainty he’s an ace in the making. Since returning to the minors, Rodriguez has seen his swinging strike rate improve. He continues to walk too many hitters. His issues with the dreaded disease homeritis followed him back to the minors (1.23 HR/9). One straightforward path forward for Rodriguez is to get his BABIP and home runs in order. He posted a .372 BABIP and 2.58 HR/9 in his big league time. Per his 3.87 xFIP, which assumes a league-average BABIP and HR/FB ratio, a small adjustment could be all that’s needed.

Endy Rodriguez, 23, C, PIT (AAA)
227 PA, 4 HR, 4 SB, .245/.326/.380

Entering this year, Rodriguez appeared to be on the cusp of promotion. Since then, Davis leapfrogged him. Rodriguez’s surprise 2022 campaign was built upon a sturdy foundation of discipline and high-quality contact. The switch-hitter remains disciplined, but his contact profile has taken a step back. His exit velocities are acceptable but unexceptional. He isn’t hitting many fly balls with authority. The one thing I see jumping out in the data is a sharp surge in opposite-field contact. That indicates… something. Of what, I can’t be certain. Likely, the Pirates advised him to balance his previously pull-heavy approach. Perhaps reembracing his past tendencies might be the way forward.

Kyle Harrison, 21, SP, SFG (AAA)
47.1 IP, 15.21 K/9, 7.04 BB/9, 3.42 ERA

From the four numbers reported above, the one that stands out is the walk rate. The good news: over his last five starts, he has allowed 4.35 BB/9. There’s no doubt about his ability to miss bats. It’s less certain if he’ll develop the command necessary to start. The Giants are carefully managing Harrison’s workload – perhaps with an eye on using him in the Majors later this season. He often works on six or more days of rest, and he’s yet to face 20 batters in a start. Even when he no-hit the Dodgers affiliate, Harrison was removed after four innings. If he arrives this season, such usage leads me to expect a bulk relief role. Those hoping Harrison will take the place of Alex Cobb are liable to be disappointed.

Brandon Pfaadt, 24, SP, ARI (AAA)
(AAA) 44 IP, 10.43 K/9, 2.25 BB/9, 3.89 ERA

Like Grayson Rodriguez, Pfaadt had a rough go in his first taste of the Majors. He posted a 8.37 ERA. Unlike Rodriguez, ERA estimators didn’t care for his effort (7.16 FIP, 5.38 xFIP). In four starts since returning to the minors, Pfaadt has posted a 3.86 ERA with 21 strikeouts in 18 2/3 innings. Home runs continue to plague him, although that’s hard to hold against a pitcher in the PCL. When he was demoted, the Diamondbacks noted they would work on mechanical issues to get him back up to snuff. At his best, Pfaadt features four pitches he can use to generate whiffs.

Harry Ford, 20, C, SEA (A+)
280 PA, 8 HR, 13 SB, .249/.411/.410

The Mariners find themselves faced with a classic conundrum. Ford’s bat is substantially ahead of his glove. He could move to an easier-to-learn position and perhaps debut in 2024. As a catcher, we should expect him to advance level-to-level with a debut in 2026. Even then, it’s possible he’ll quickly move off the position like Daulton Varsho. Ford features excellent plate discipline and above-average power. His hit tool is trending as middling. The Varsho parallel is made all the more obvious by Ford’s rare speed for a catcher – a trait which would just so happen to make learning another position relatively easy. Reports (and journalists) praise Ford for his work ethic and amiability.

Three More

Junior Caminero, TBR (19): Though his pace has slowed since reaching Double-A, Caminero continues to thrive at the plate. One of the youngest players at the level, he’s hitting .297/.347/.438 in 72 plate appearances with two home runs. Encouragingly, his walk rate is up two points from his time in High-A. Many expect discipline to determine his final outlook.

Tsung-Che Cheng, PIT (21): One of the top-performing hitters in the minors, Cheng has greatly improved his prospect status this season. Defensively capable all over the infield, he’s now showing multi-faceted capacity as a hitter too. His once-minus power is approaching average. His plus discipline, contact, and speed could help the total package to play up.

Andrew Abbott, CIN (24): Abbott, who we covered in more detail shortly before his debut, is now 17 2/3 scoreless innings into his career. It’s looking rather fluky. ERA estimators range from 3.50 to 5.50. After missing piles of bats in the minors, he’s suddenly no longer inducing whiffs. He also isn’t avoiding hard contact. If nothing changes, the other shoe will drop in a big way. He’s an extreme fly ball pitcher with Great American Ball Park as his home.

Injured List Activations: Davies, Whitlock

By | at

Updates on some prominent players returning from the injured list…

  • The Diamondbacks reinstated Zach Davies from the 15-day IL, while also calling up Drey Jameson from Triple-A and optioning right-handers Brandon Pfaadt and Luis Frias.  Davies made just two starts and threw 9 1/3 innings before going on the IL in early April due to a strained left oblique, but he’ll now return to Arizona’s rotation, beginning with tonight’s game against the Red Sox.  Between Davies’ injury and Madison Bumgarner’s release, the D’Backs have turned to several of their younger pitchers to try and stabilize the rotation, but none of Ryne Nelson, Tommy Henry, Pfaadt, or Jameson have done particularly well in starting duty.
  • Garrett Whitlock will be the opposing starter against Davies tonight, as the Red Sox have activated the right-hander from the 15-day IL.  The corresponding move took place yesterday, as Boston optioned left-hander Brennan Bernardino to Triple-A following Friday’s 7-2 win over the D’Backs.  Whitlock has missed a month due to ulnar neuritis, or essentially inflammation of the funny bone near his right elbow.  Whitlock has a 6.19 ERA over three starts and 16 innings this season, and while his results as a starter have been middling over the last two seasons, the Red Sox will continue to give Whitlock looks in the rotation.  Struggling veteran Corey Kluber will be moved to the bullpen to accommodate Whitlock’s return to the starting five.

Diamondbacks Designate Seth Beer For Assignment

By | at

The D-backs announced Wednesday that they’ve designated first baseman/designated hitter Seth Beer for assignment. His spot on the 40-man roster will go to top pitching prospect Brandon Pfaadt, whose previously reported promotion has now been formally announced by the team. Righty Peter Solomon was optioned to Triple-A Reno to clear a spot for Pfaadt on the 26-man roster. Pfaadt will make his MLB debut and start today’s game for Arizona.

Beer, 26, was acquired from the Astros alongside Josh Rojas, Corbin Martin and J.B. Bukauskas in the 2019 deadline trade that sent Zack Greinke to Houston. He’s seen brief MLB time in the past two seasons but posted a .208/.294/.292 batting line in a total of 136 plate appearances.

Broadly speaking, Beer has a much more productive track record in Triple-A, where he’s batted .260/.370/.460 with 32 home runs, 55 doubles, an 18.2% strikeout rate and a 9.7% walk rate in 916 trips to the plate. That said, the year-to-year breakdown of Beer’s Triple-A production is less encouraging. After posting a strong .287/.398/.511 batting line there in 2021 (128 wRC+), his numbers dipped to about league-average in 2022 and have fallen all the way to a .200/.266/.314 slash in 79 plate appearances to begin the current season.

Beer, the No. 28 overall pick in the 2018 draft, was always viewed as a bat-first prospect who’d need to hit at a very high level to justify his lack of speed and defensive upside. He did that up through the 2021 season, but the past two years have brought about a downturn. That said, he still has a minor league option remaining beyond the current season, so a team in need of a left-handed bat with some power potential could view the 26-year-old as an intriguing buy-low candidate. The D-backs will have a week to trade Beer or attempt to pass him through outright waivers. If he were to go unclaimed, he wouldn’t have the ability to decline the assignment, as he has neither three years of MLB service nor a prior outright assignment in his career.

Diamondbacks To Promote Brandon Pfaadt

By | at

The Diamondbacks are going to promote pitching prospect Brandon Pfaadt to make his major league debut tomorrow, reports Nick Piecoro of the Arizona Republic. The right-hander isn’t currently on the club’s 40-man roster, meaning they will need to open a spot for him between now and then.

Pfaadt, 24, was a fifth round pick of the club in the 2020 draft. The minor leagues were canceled by the pandemic that year, but Pfaadt emerged with a strong showing in 2021. He rose through three levels of the minors, going from Single-A to High-A and Double-A that year, tossing 131 2/3 innings total with a combined 3.21 ERA. He struck out 30.2% of batters faced while walking just 5.3%. After that strong showing, he was ranked the club’s #10 prospect by Baseball America going into 2022.

Last year, Pfaadt would continue to impress, throwing 167 innings between Double-A and Triple-A  with a 3.83 ERA, 31.6% strikeout rate and 4.6% walk rate. Going into this season, he was ranked the club’s #5 prospect by BA but amazingly was #26 in the entire league, highlighting a strong and top-heavy system loaded with premier prospects. Their report highlights his fastball, which averages around 93-94mph and has natural cutting action. His slider is his putaway pitch but he also has a changeup and a curveball. He is listed as the #51 prospect in the league at MLB Pipeline, #16 at FanGraphs, #32 at ESPN and was ranked #38 by Keith Law of The Athletic.

The righty was sent to Triple-A to start this year, where he’s posted a 3.91 ERA through five starts, striking out 28.6% of opponents while walking just 5.7%. As he’s been doing that, the Diamondbacks have been playing well, 16-13 record, despite an inconsistent rotation. Zac Gallen and Merrill Kelly have been their typically excellent selves so far this year, but the rest of the group hasn’t been nearly as strong. Madison Bumgarner got released after posting a 10.26 ERA in his first four starts. Ryne Nelson has a 6.39 ERA after six outings while Tommy Henry has a 6.52 after a pair. Zach Davies is on the injured list with an oblique strain while Drey Jameson was optioned out after some struggles.

Amid all of that uncertainty, the club will give Pfaadt a shot and see how he fares against big league hitters. Since the season is over a month old already, he won’t be able to earn a full year of service time, at least not the traditional way. The latest collective bargaining agreement has a couple of measures to discourage teams from trying to manipulate a player’s service time and delay their free agency. One of those measures is that a player can still get a full service year even if they didn’t spend the requisite 172 days in the majors. Any player with less than 60 days’ service time at the start of a season who is on two of the top 100 prospect lists at Baseball America, ESPN or MLB Pipeline can still get a full year if they finish in the top two of Rookie of the Year voting. Both Adley Rutschman and Michael Harris II managed to get a full year of service this way last year.

Pfaadt is on all three lists and could follow that path, though it will be a bit of a challenge. He will have to chase down other rookies who have already spent a month accruing stats, such as James Outman or his teammate Corbin Carroll. But for the Diamondbacks, it’s an exciting time as Pfaadt joins Carroll, Gabriel Moreno and other exciting young players on the roster, with prospects like Jordan Lawlar and Druw Jones set to join them in the upstart D’Backs in the years to come.

Diamondbacks Option Jake McCarthy, Drey Jameson

By | at

The Diamondbacks optioned right-hander Drey Jameson to Triple-A Reno yesterday, opening up a roster spot for lefty Tommy Henry, who was recalled and started last night’s game. Today, the club is optioning outfielder Jake McCarthy as well, reports Nick Piecoro of the Arizona Republic, recalling infielder Emmanuel Rivera in a corresponding move.

Individually, the moves aren’t necessarily shocking. Both players have started a bit slow here in the early parts of this season and neither is fully established. Each player is 25 years old and came into this year with less than a year of service time. But their demotions, as well as Madison Bumgarner recently getting designated for assignment, perhaps point to the club having more of a win-now mentality than recent years.

The D’Backs went 25-35 in the shortened 2020 season before winning just 52 games the season after and 74 last year. The silver lining of those losing seasons is that they’ve been able to devote playing time to young players like Josh Rojas, Corbin Carroll, Christian Walker and others, who were able to use those opportunities to hone their skills cement themselves as viable big leaguers to varying degrees.

But this year, the club’s emerging young core has helped them jump out to a 13-11 start. With the Dodgers having a modest offseason and feeling less like inevitable conquerors while the Padres and Giants have had slow starts, the D’Backs find themselves leading the American League West. In order to stay that up there, it seems there’s less room for players to develop in the big leagues.

McCarthy looked to have taken a step forward last year, hitting .283/.342/.427 for a wRC+ of 116 while also stealing 23 bases. With him in the outfield alongside Carroll and Alek Thomas, the club felt good enough about its options on the grass to trade Daulton Varsho to the Blue Jays in the offseason. They did get Lourdes Gurriel Jr. back in that deal for some insurance, though he’s a short-term add since he’s an impending free agent. McCarthy hasn’t been able to carry over those results so far, hitting just .143/.229/.238 prior to today’s move. He’s surely due for some regression from a .160 batting average on balls in play, but he’s also not hitting the ball with much authority. He’s currently in the 9th percentile in terms of average exit velocity, 8th in hard hit rate and 34th in barrel rate. He’ll head to Triple-A to try to get into a groove.

As for Jameson, his numbers might not look disastrous at first glance, as he has a 3.71 ERA through six appearances. However, he hasn’t exactly been racking up the outs. He started the season in the bullpen and made three long relief appearances, but then was moved to the rotation when Zach Davies landed on the injured list. His first start was solid, tossing four shutouts innings against the Brewers, throwing 54 pitches in the process. His next start wasn’t quite as good, as he threw 71 pitches but logged only 3 2/3 innings against the Cardinals. Then on Sunday, he only lasted one inning against the Padres. It took him 43 pitches, allowing three hits, three walks and three earned runs in the process.

“If he pitched better, he’d still be here,” manager Torey Lovullo said frankly yesterday, per Theo Mackie of the Arizona Republic. “That’s one of the things that (General Manager Mike Hazen) told him. A 43-pitch first inning puts us way behind, we’re kind of in a box, we’ve got to play a little catchup now with our bullpen. This was a direct response to what he did yesterday and a little bit of what he did in St. Louis as well.”

Those comments seem to reflect the win-now mentality that the club currently has. “We felt like the best thing for Drey at this point in time is to go down, get his timing, get his rhythm and find his stuff,” Lovullo said. “I said it last night: Good major league hitters, when they know you’re throwing a fastball, will get wood on a bullet. I stand by his ability to make pitches and when he does, he’s going to find his way back here.”

With Jameson going to Reno to try to earn his way back to the majors and Bumgarner out of the picture, the club is down to four starters on the roster in Zac Gallen, Merrill Kelly, Ryne Nelson and Henry. They have some off days coming up that could allow them to get by with that group, but it sounds like that’s not the plan. “We have discussed the four-man,” Lovullo said. “We know the off days are there. It was thrown around. We have not made any decisions, but I don’t think a four-man rotation right now is anything we’re interested in.”

Since the club needs a fifth starter, it makes speculative sense that a promotion of prospect Brandon Pfaadt could be imminent, though the club hasn’t made any kind of official announcement in that department. A telling sign could be if he makes his next scheduled start, as he’s currently slated to take the ball for Reno on Wednesday. A consensus top-50 prospect in the league, Pfaadt isn’t on the 40-man roster and would require a corresponding move if he gets the call. He has a 3.54 ERA through four starts in Triple-A this year, striking out 30.1% of batters faced while walking 4.8%.

The Diamondbacks entered Spring Training with four rotation spots in place. Zac Gallen and Merrill Kelly are the top two on the staff. Madison Bumgarner will get another crack in the middle, while Arizona brought back Zach Davies on a one-year free agent deal to take a back-end spot.

Who would secure the fifth spot was one of the more interesting decisions for the Snakes in camp. As MLBTR’s Darragh McDonald explored in early January, that battle looked likely to come down to four hurlers: Ryne Nelson, Drey Jameson, Tommy Henry and Brandon Pfaadt. Jameson and Nelson, both of whom made their big league debuts late in the 2022 season, seemed the early favorites.

That indeed now appears to be a two-person race. Arizona reassigned Pfaadt, who is not yet on the 40-man roster, to minor league camp over the weekend. They optioned Henry to Triple-A Reno this afternoon, taking him out of consideration for an Opening Day job as well.

Neither Jameson nor Nelson has done much to seize the job this spring. The former has allowed eight runs in 9 2/3 innings, while the latter has been tagged for nine runs in the same amount of work. Jameson has at least managed a solid 12:3 strikeout-to-walk ratio, while Nelson’s 10:6 mark is less impressive.

Both pitchers fared well in very limited MLB looks last year. Jameson made four starts and posted a microscopic 1.48 ERA through 24 1/3 innings. That came with an excellent 56.1% grounder percentage and above-average strikeout and walk numbers. It was a very strong debut effort but won’t completely erase concerns about the ghastly 6.95 ERA he’d posted over the 114 Triple-A innings he’d thrown prior to his promotion. Reno is among the hardest places in affiliated ball to pitch, which certainly didn’t do him any favors. That said, some prospect evaluators have suggested the Ball State product is likelier to settle into a bullpen role than a rotation because of concerns about his command.

Nelson has had some relief concerns himself, though he’s generally credited for more advanced command than Jameson. He doesn’t throw quite as hard and didn’t miss as many bats in his brief big league look as Jameson did. Nelson had similarly strong bottom line numbers in a cup of coffee, however, allowing four runs in 18 1/3 big league frames. Over 136 innings in Reno, he’d posted a 5.43 ERA with roughly average strikeout and walk numbers.

Henry had the most MLB work of this group in 2022, starting nine games. He didn’t find the early success of Jameson or Nelson, pitching to a 5.36 ERA with below-average strikeout and walk rates in 47 innings. Henry allowed 11 runs in 16 1/3 frames in camp before being optioned. Pfaadt is arguably held in the highest regard of the bunch but is the only one who hasn’t made his big league debut. The 24-year-old made 19 starts at Double-A Amarillo and 10 with Reno last season, combining for a 3.83 ERA in 167 innings. He allowed five runs with 15 strikeouts and four walks in 12 innings this spring.

Looking At The Diamondbacks’ Rotation Options

By | at

It’s been a rough few years for the Diamondbacks. After making the playoffs in 2017 and then posting respectable records above .500 in the two following seasons, the last three campaigns have seen their fortunes sink. They finished last in the National League West in 2020 and 2021, then surpassed the Rockies last year for a fourth place finish. During that time, the Dodgers, Giants and Padres have all had strong seasons, making the efforts of the D-Backs feel particularly hopeless. In 2021, they finished 52-110 and 55 games out in the division.

2022 was a step in the right direction, though, and there are some exciting ingredients in place. The position player mix seems to have a lot of good momentum behind it. Even after dealing Daulton Varsho to the Blue Jays, the outfield should feature a crop of exciting youngsters, headlined by Corbin Carroll but with Alek Thomas and Jake McCarthy also in the mix. On the infield, Ketel Marte is capable of MVP-level production when healthy and at his best. Christian Walker is underrated at first base while shortstop Jordan Lawlar and catcher Gabriel Moreno are considered some of the best prospects in the league.

However, the pitching staff is a bit more precarious at the moment. In 2022, the position players posted a cumulative tally of 19.8 wins above replacement, according to FanGraphs, good enough for 15th place in the majors. But the pitchers posted a total of 7.7 fWAR, ranking them 27th. If the team is to re-emerge and start contending again, they will need to get better results from the mound. There were some potentially encouraging developments in their rotation in 2022, but still some uncertainty going forward into 2023.

It’s possible that the club will make further additions via free agency but it’s also possible that they’re done. The club’s payroll is now at $113MM, per the calculations of Roster Resource. They’ve been as high as $132MM in the past, according to Cot’s Baseball Contracts, but they were at just $91MM last year. That means they’ve already boosted the budget by more than $20MM. For now, let’s take a look at the in-house options, starting with the four veterans.

Zac Gallen

Gallen, 27, seemed to emerge as an ace in 2019 and 2020, making 27 starts with a 2.78 ERA. He had a swoon in 2021, dealing with various injuries and his ERA jumped to 4.30, but he was back in form last year. In 2022, he made 31 starts and logged 184 innings with a 2.54 ERA, 26.9% strikeout rate, 6.6% walk rate and 46% ground ball rate. He finished fifth in the voting for the National League Cy Young award and can be controlled via arbitration for three more seasons.

Merrill Kelly

Kelly, 34, parlayed a strong run in the KBO into a two-year deal with the Diamondbacks prior to the 2019 season. That deal also came with a pair of club options. Kelly pitched well enough that they triggered both options and then gave him an extension that runs through 2024 with a club option for 2025. Through four seasons with Arizona so far, he has a 3.96 ERA, 20.8% strikeout rate, 6.9% walk rate and 43% ground ball rate. He’s certainly a notch below Gallen, but he’s a solid mid-rotation option for the club.

Madison Bumgarner

After spending over a decade with the Giants, Bumgarner came to the D-Backs prior to the 2020 season on a five-year, $85MM deal. Unfortunately, his results immediately took a nosedive after the uniform switch. He had a 3.13 career ERA in his time with the Giants but has posted a 4.98 mark in his three seasons as a Snake. His walk rate is still better than average but his strikeouts have vanished. He punched out 23.9% of opponents on his previous team but it’s been just a 17.7% rate for Arizona. Now 33 years old, it’s hard to expect a sudden bounceback, though the Diamondbacks might give him a chance to try since he still has two years and $37MM left on his deal. That gives him negative trade value at this point and it would be a lot of cash to eat for a Diamondbacks team that’s never been a top spender. However, his salary goes from $23MM this year to $14MM in 2024, which could make some kind of transaction more plausible if he can find better results in 2023.

Zach Davies

Davies, 30 in February, pitched for the D-Backs in 2022. He didn’t blow anyone away but he was passable enough. He made 27 starts with a 4.09 ERA. His 17.9% strikeout rate was a few ticks below average but his 9.1% walk rate and 42.9% ground ball rate were both right around league average. He used his five-pitch mix to keep hitters from doing damage, as his hard hit rate was in the 76th percentile among qualified pitchers and his average exit velocity was in the 75th. The club agreed to a new one-year deal with him yesterday, bringing him back to hopefully provide some steady production while they evaluate their younger pitchers.

Ryne Nelson

If those four pitchers are healthy and throwing well, there will be one spot remaining for a younger pitcher. Nelson will certainly be in that mix to secure the final job. He was selected by Arizona in the second round of the 2019 draft and has been considered one of the club’s better prospects since then. He even cracked Baseball America’s top 100 list of all prospects in the league going into 2022. Last year saw him spend most of his time with the Triple-A Reno Aces, who play in the Pacific Coast League. He made 26 starts for that club with a 5.43 ERA in what is a notoriously hitter-friendly environment. His 21.6% strikeout rate and 7.9% walk rate were solid enough for him to get a major league debut in September. He made three starts in the big leagues with a 1.47 ERA, striking out 23.2% of batters faced while walking 8.7% of them. That’s a very small sample size but an encouraging one nonetheless. He’ll turn 25 in February and still has a full slate of options. He could certainly be sent back to Triple-A but an extended audition at the big leagues could be warranted as well.

Drey Jameson

Jameson and Nelson have a very similar trajectory to this point. Jameson was also selected in the 2019 draft, just ahead of Nelson by being selected between the first and second rounds, with the pick the club received for AJ Pollock signing with the Dodgers. Jameson began 2022 in Double-A but posted a 2.41 ERA in four starts and got quickly moved up to Triple-A. With the Aces, he posted a 6.95 ERA in 114 innings in that pitcher-hostile environment. However, his rate stats were decent, striking out 21.2% of hitters, walking 8.2% of them and getting grounders on 48.6% of balls in play. He also got called up to the big leagues in September, just like Nelson, making four starts with a 1.48 ERA, 24.5% strikeout rate, 7.1% walk rate and 56.1% ground ball rate. Just like Nelson, he’ll be 25 years old this season and has a full slate of options. The two seem likely to be battling each other for the final rotation spot with one likely to be optioned, but they could also both be in the mix as soon as an injury pops up.

Tommy Henry

Just like Nelson and Jameson, Henry was also nabbed in the 2019 draft. He was selected in competitive balance round B, between the second and third rounds. He posted stronger Triple-A results than the other two last year, with a 3.74 ERA over 21 starts. However, his first taste of the big leagues didn’t go as smooth as he made nine starts with a 5.36 ERA, striking out just 17.6% of hitters while walking 10.2% of them. He’s also 25 and provides a third competitor in the battle for the last rotation job, but it’s possible he’s a bit behind Nelson and Jameson based on his weaker debut. He still has a full slate of options and could be in line for more work in the minors, ready to make the jump again when needed and ready.

Brandon Pfaadt

Pfaadt, 24, began 2022 in Double-A, making 19 starts and logging 105 1/3 innings there. His 4.53 ERA might not look special, but he posted that number despite striking out 32.2% of batters faced and walking just 4.3% of them. A .370 batting average on balls in play surely inflated that ERA to a level higher than he deserved, though 17.9% of his fly balls turning into home runs may have contributed as well. The D-Backs seemed to be willing to look past that ERA, bumping him to Triple-A in August. Pfaadt took very well to the move, despite the strong offensive environment. He tossed 61 2/3 innings over 10 starts for the Aces with a 2.63 ERA, 30.6% strikeout rate and 5.8% walk rate. Based on that strong finish, he has surged up prospect rankings. He currently has the #83 slot at Baseball America, is #90 at MLB Pipeline, but FanGraphs is especially bullish and considers him the 25th best prospect in the league. He’s not yet on the club’s 40-man roster since he was only drafted in 2020 and isn’t Rule 5 eligible until this coming December, but he seems destined to make a big league debut well before then.

____________________

When combined, there are some strong elements here for the D-Backs. Gallen gives them an ace and Kelly a solid piece for the middle of the rotation. Davies isn’t terribly exciting but is fine as a backend piece. Bumgarner’s contract is underwater at this point, but he could also be a solid backend guy if he puts the past three years behind him. Those four combined don’t give the club an especially strong rotation, but the four guys behind them give the overall group plenty of upside. If one or two of the young guys have a breakout in 2023, then the rotation picture starts to look much better.

The position player core in Arizona is heavily future-focused, with Carroll, Thomas, Marte, Moreno, Lawlar and others starting to develop into a strong core that could allow the club to continually improve over the coming seasons. With the rotation, the path forward could be very similar. Prospects aren’t sure things, especially when it comes to pitchers, but the Diamondbacks need to hit on young players if they’re not going to spend like the Dodgers, Padres and Giants. For now, there are signs of hope in the desert and the upcoming season will be a fascinating one to watch.
