Diamondbacks Rumors

Diamondbacks Select Humberto Castellanos

By | at

The D-Backs announced they’ve selected right-hander Humberto Castellanos onto the major league roster. Arizona also recalled lefty reliever Joe Jacques from Triple-A Reno, a move which was reported this afternoon. To clear the necessary spots on the MLB roster, the Snakes optioned southpaw Brandon Hughes and placed lefty Blake Walston on the 15-day injured list with inflammation in his throwing elbow. Arizona also reinstated righty Luis Frías from the 15-day IL and optioned him to Reno.

Arizona had an opening on the 40-man roster, which they’ll use to give Castellanos his first MLB look in two years. The Mexican-born hurler pitched in 25 games, including 16 starts, for the D-Backs between 2021-22. He turned in a 5.30 ERA over 90 innings before undergoing Tommy John surgery in August 2022. That led Arizona to outright him off their roster at the end of the season and forced him to sit out all of last year.

The Diamondbacks brought Castellanos back on a minor league contract over the winter. He’s healthy again and has logged 43 2/3 innings over 10 appearances in Triple-A. Castellanos has a 4.57 earned run average that is quite impressive considering Reno is among the toughest places to pitch in affiliated ball. He has punched out a solid 24.3% of opposing hitters, although he has also issued walks at a career-high 11.4% rate.

For most of his MLB career, Castellanos has shown the opposite profile: plus control without the ability to miss many bats. He has a modest 16.6% strikeout rate with a 7.3% walk percentage in 100 2/3 innings between the Astros and D-Backs. Castellanos doesn’t throw especially hard, but he can work out of the rotation or in long relief for Torey Lovullo. He still has a minor league option, allowing the Diamondbacks to send him back to Reno at any point without putting him on waivers.

Walston, a first-round pick in 2019, has made his first three MLB appearances this season. The North Carolina native has allowed four runs over 12 2/3 innings, striking out 11 against nine walks. It’s not clear how long he’ll be out of action. The Diamondbacks will presumably play things cautiously with any elbow issue for one of their more talented young pitchers.

Diamondbacks Claim Thyago Vieira

By | at

The D-backs claimed hard-throwing righty Thyago Vieira off waivers from the Orioles, who’d previously designated him for assignment, per an announcement out of Baltimore. The Diamondbacks already have two open spots on the 40-man roster and thus will only need to open a 26-man roster spot for the out-of-options Vieira.

Vieira isn’t the only bullpen move coming for the Snakes, however. Ari Alexander of KPRC-2 reports that they’re calling lefty Joe Jacques up from Triple-A Reno for what’ll be the southpaw’s team debut. Arizona claimed Jacques off waivers from Boston back in April.

The 30-year-old Vieira made just one appearance for the O’s, who acquired him from the Brewers following a separate DFA. He faced five batters in his lone Orioles appearance but didn’t record an out, yielding a hit and four walks. He’d go on to be charged for three earned runs. He also struggled through 22 1/3 innings in Milwaukee and currently sports an ugly 6.85 ERA on the season. In 51 career innings at the MLB level, Vieira has a 6.71 ERA with a 20.7% strikeout rate and bloated 13% walk rate.

It’s a nondescript track record, but Vieira is also one of MLB’s hardest throwers, averaging 98 mph on his heater and frequently touching triple digits. Command has been an ongoing issue for him, but the raw power of his repertoire continues to pique teams’ interest. The right-hander also had a nice run with the Yomiuri Giants of Japan’s Nippon Professional Baseball from 2020-22, posting a 3.61 ERA with a hearty 26.2% strikeout rate. Since Vieira is out of minor league options, he’ll immediately join the big league bullpen, but that lack of flexibility could also have him on a short leash if he continues to struggle as he did in Milwaukee and Baltimore.

Both Vieira and Jacques will add fresh arms to an Arizona bullpen that needed to cover seven innings in a blowout loss after Jordan Montgomery lasted just two innings. Relievers Bryce Jarvis, Brandon Hughes and Logan Allen all pitched at least two innings yesterday and figure to be unavailable today if at all possible. Righty Kevin Ginkel threw 35 pitches a day prior as well, adding to the currently taxed nature of manager Torey Lovullo’s relief corps.

MLB Issues Lifetime Ban To Tucupita Marcano For Betting On Baseball, Announces Four Other One-Year Suspensions

By | at

Major League Baseball announced Tuesday morning that Padres infielder Tucupita Marcano has been declared permanently ineligible for violating the league’s sports betting rules and policies — specifically Rule 21(d)(2). Per this morning’s press release:

In March 2024, MLB learned from a legal sports betting operator that it had identified past baseball betting activity from accounts connected to multiple Major and Minor League players.  MLB obtained data from that operator and other sportsbooks, including authentication data for bets.  None of these players played in any game on which they placed a bet.  Further, all of the players denied that they had any inside information relevant to the bets or that any of the baseball games they bet on were compromised or manipulated, and the betting data does not suggest that any outcomes in the baseball games on which they placed bets were compromised, influenced, or manipulated in any way. None of the players are appealing their discipline.

Under Major League Rule 21, “Any player, umpire, or Club or League official or employee, who shall bet any sum whatsoever upon any baseball game in connection with which the bettor has no duty to perform, shall be declared ineligible for one year.” Whereas, “Any player, umpire, or Club or League official or employee, who shall bet any sum whatsoever upon any baseball game in connection with which the bettor has a duty to perform, shall be declared permanently ineligible.”

MLB’s investigation found that from Oct. 16-23, 2022 and from July 12 to November 1, 2023, Marcano placed 387 bets on baseball, including 25 bets on Pirates games where he was a member of Pittsburgh’s roster. All 25 of those Pirates bets came while Marcano was rehabbing from a season-ending ACL tear, so he did not appear in any of the games in question. The bets nonetheless violate the league policy and have thus triggered the lifetime ban.

The league’s investigation found that Marcano placed more than $150K worth of bets on baseball. Most of the bets in question were parlays, some including his own (at the time) Pirates club. Marcano’s bets typically involved the Pirates winning the game or were over/under bets on the number of runs scored within the game.

Major League Baseball also announced that Athletics right-hander Michael Kelly, Diamondbacks lefty Andrew Saalfrank, Padres minor league pitcher Jay Groome and Phillies minor league infielder Jose Rodriguez have been given one-year bans for violating Rule 21(d)(1). All four players were found to have made bets on Major League Baseball games but were not on the Major League roster or injured list of any teams involved in the bets they placed.

Kelly, 31, is an active member of the Athletics’ bullpen and has pitched to a 2.59 ERA in 31 1/3 innings this season. His bets were all placed in Oct. 2021, when the right-hander was with the Astros’ Triple-A affiliate. He made only ten bets for a total of $99.92, with three of those bets coming on games involving the Astros’ big league club during the postseason. Despite the meager total of Kelly’s bets, his gambling activity was a violation of the rule in place and will trigger that one-year ban.

Similarly, each of Saalfrank ($445), Groome ($453) and Rodriguez ($749) bet under $1,000 on Major League games back in 2020-21. All were minor league players at the time — Saalfrank with Arizona’s Low-A team, Groome with the Red Sox’ High-A affiliate and Rodriguez with the White Sox’ Double-A club.

Commissioner Rob Manfred issued the following statement on today’s suspensions:

“The strict enforcement of Major League Baseball’s rules and policies governing gambling conduct is a critical component of upholding our most important priority: protecting the integrity of our games for the fans. The longstanding prohibition against betting on Major League Baseball games by those in the sport has been a bedrock principle for over a century. We have been clear that the privilege of playing in baseball comes with a responsibility to refrain from engaging in certain types of behavior that are legal for other people. Since the Supreme Court decision opened the door to legalized sports betting, we have worked with licensed sports betting operators and other third parties to put ourselves in a better position from an integrity perspective through the transparency that a regulated sports betting system can provide. MLB will continue to invest heavily in integrity monitoring, educational programming and awareness initiatives with the goal of ensuring strict adherence to this fundamental rule of our game.”

Matt Bowman Elects Free Agency

By | at

Reliever Matt Bowman has elected free agency after being designated for assignment by the Diamondbacks on Sunday, tweets Alex Weiner of Arizona Sports. The right-hander, who turned 33 today, went unclaimed on outright waivers.

Bowman pitched in four games for Arizona, allowing six runs over 6 2/3 innings. The Snakes had acquired him from the Twins in a cash trade on May 2. Bowman had pitched five times for Minnesota as well. He allowed eight runs in 14 1/3 frames with 10 strikeouts and six walks between the two teams. That’s already the Princeton product’s heaviest MLB workload since 2019.

Injuries essentially robbed Bowman of the 2020-22 seasons. He underwent Tommy John surgery late in the ’20 campaign and didn’t return to full health until last season. Bowman spent most of last year in Triple-A with the Yankees, turning in a 3.99 ERA with a decent 22.6% strikeout rate and a strong 51.9% grounder percentage over 58 2/3 innings. New York briefly called him to the majors last fall but cut him loose at season’s end.

Bowman signed with Minnesota on a non-roster contract and again pitched well in Triple-A. He didn’t allow an earned run over his six innings, leading the Twins to call him up during the second week of April. Bowman is out of options, so Minnesota couldn’t send him back to the minors once they added him to their 40-man roster. That led to his trade to Arizona, but Bowman struggled in his limited time in the desert. Based on his recent Triple-A production, he shouldn’t have any problem finding a new minor league deal now that he’s back on the open market.

Diamondbacks Place Zac Gallen On Injured List

By | at

The Diamondbacks announced that right-hander Zac Gallen has been placed on the 15-day injured list due to a right hamstring strain. Fellow righty Slade Cecconi has been recalled in a corresponding move.

Gallen, 28, took the ball in last night’s game against the Mets but departed after just six pitches, with the club later announcing the hamstring strain. There were some signs pointing to a mild injury, as manager Torey Lovullo told Arizona Sports’ Burns & Gambo show earlier today that he expected Gallen to miss one start without going on the IL, as relayed by Alex Weiner of Arizona Sports. Though it seems the club decided to put him on the IL after all, putting him out of action for the next two weeks at least.

Even if it does prove to be a short absence, it’s not good news for the Snakes, as Gallen has emerged as one of the better pitchers in baseball in recent years. In 725 career innings, he has allowed 3.20 earned run per nine frames. Since the start of 2022, he has a 3.05 ERA, 26.3% strikeout rate, 6.1% walk rate and 43.3% ground ball rate.

Subtracting that kind of performance would hurt any rotation but it’s especially concerning for the Diamondbacks, as Gallen now joins Merrill Kelly and Eduardo Rodríguez on the injured list. The defending National League champions have gotten out to a slow start so far this year and are currently 25-31. Climbing back into a playoff position will be tough without those three pitchers and neither Kelly nor Rodríguez have started a rehab assignment yet, so the club will definitely be hoping that Gallen just needs a quick breather before returning.

For now, the club’s rotation consists of Jordan Montgomery, Brandon Pfaadt, Ryne Nelson, Blake Walston and Cecconi. Both Nelson and Cecconi have an ERA over 6.00. Montgomery is at 4.69 and Pfaadt at 4.16. Walston’s ERA is just 2.16 but in a tiny sample of 8 1/3 innings. Tommy Henry is on optional assignment, though he has a 5.40 ERA in the majors so far this year. Cristian Mena is also on the 40-man roster but has yet to make his major league debut.

Diamondbacks Release Kolten Wong

By | at

The D-backs have released veteran infielder Kolten Wong, per the transaction log at MiLB.com. Wong had been playing with their Triple-A affiliate in Reno after signing a minor league contract. He’s now a free agent.

A two-time Gold Glove winner at second base, the now-33-year-old Wong entered the 2024 campaign in hopes of rebounding from a disastrous 2023 season that saw him bat just .183/.256/.263 in 250 plate appearances between the Mariners and Dodgers. Wong signed a minor league deal with Baltimore and spent spring training with the Orioles but opted out of that pact when he didn’t make the team. He subsequently signed with the D-backs, putting pen to paper on a second minor league deal back on April 10.

Through 31 games, Wong has turned in a .271/.339/.383 batting line that looks respectable enough relative to MLB batting lines but is about 18% worse than average (by measure of wRC+) in the supercharged offensive environment of Triple-A’s Pacific Coast League. He’s homered twice, swiped a pair of bags and collected six doubles. Wong has also shown modest improvements in his strikeout and walk rates, which sat at 21.2% and 7.2% in the big leagues last year but are at 18.2% and 8.3% in Reno.

Miserable as Wong’s 2023 season was, the veteran infielder is still just one season removed from a .251/.339/.430 performance with the 2022 Brewers — a season that saw him swipe 17 bases and club a career-best 15 home runs with a strong 9.3% walk rate and considerably lower-than-average 17.7% strikeout rate. From 2017-22, Wong was an above-average regular at second base between St. Louis and Milwaukee, hitting a combined .269/.349/.414 with 54 homers, 72 steals, a roughly average walk rate, strong bat-to-ball skills and plus defense.

The D-backs haven’t needed any help at second base with Ketel Marte logging a .275/.322/.493 slash in his first 233 trips to the plate this season, and there are other second base options on the 40-man roster ahead of Wong on the depth chart as well. But there are plenty of teams around the game — Red Sox, White Sox and Angels, to name a few — that have struggled to get much of anything out of their second basemen this season. Wong could make sense as a depth option with any of those clubs or even an immediate big league replacement in some spots, if a team wants to send a struggling young player back to Triple-A for some more seasoning.

Diamondbacks Designate Matt Bowman For Assignment

By | at

The Diamondbacks announced this afternoon that right-hander Matt Bowman has been designated for assignment. Left-hander Blake Walston was recalled to the big league roster to replace Bowman on the club’s active roster.

Bowman, who will celebrate his 33rd birthday on Friday, joined the Diamondbacks earlier this month when he was acquired in cash deal with the Twins. At the time of the deal, Bowman had been squeezed off of Minnesota’s 40-man roster despite a solid showing in five appearances, where he posted a 2.35 ERA in 7 2/3 innings of work. Unfortunately, the wheels have come off for Bowman across his four appearances with Arizona, as he’s been shelled for six runs on eight hits and two walks in 6 2/3 innings of work that have ballooned his ERA to 5.02 on the year.

A 13th-round pick by the Mets in the 2012 draft, Bowman had considerable success with the Cardinals in the first two seasons of his big league career from 2016 to ’17. In a combined 126 1/3 innings of work, Bowman posted a solid 3.70 ERA (112 ERA+) with a stronger 3.47 FIP. That seemingly portended a successful career near the back of big league bullpens, but things didn’t work out that way as Bowman struggled to well below average results with St. Louis the following season, prompting the club to part ways with him.

He pitched for the Reds in 2019 to an impressive 129 ERA+ in 32 innings of work but a series of elbow injuries, including one that required Tommy John surgery, wiped out Bowman’s 2020-22 campaigns. The veteran resurfaced with the Yankees last year but was torched for a 9.00 ERA and 6.51 FIP in four innings of work before returning to the minor leagues. Arizona will now have one week to trade Bowman or attempt to pass him through waivers. The right-hander has been outrighted previously during his big league career and as a result can reject an outright assignment in favor of free agency should he so choose.

Replacing Bowman on the club’s 40-man roster is Walston, who is slated to take the ball for today’s start against the Marlins. It’ll be the first big league start and just the second MLB appearance of Walston’s young career. Arizona’s first-round pick in the 2019 draft, the 23-year-old climbed his way through up the minor league ladder to make his big league debut earlier this year, when he struck out five in 3 2/3 innings of work against the Dodgers while allowing two runs on three hits and four walks. That admirable effort against one of the league’s most intimidating offenses has earned Walston another opportunity in the majors thanks in part to the injuries facing the Dbacks rotation. Marquee offseason signing Eduardo Rodriguez has yet to throw a pitch for the club this year due to a strained lat and he’s been joined on the 60-day injured list by veteran righty Merrill Kelly, who is battling a shoulder strain.

MLBTR Podcast: The Likelihood Of A Juan Soto Extension, What’s In Store For Pete Alonso, And Corbin Carroll’s Struggles

The latest episode of the MLB Trade Rumors Podcast is now live on Spotify, Apple Podcasts, and wherever you get your podcasts! Make sure you subscribe as well! You can also use the player at this link to listen, if you don’t use Spotify or Apple for podcasts.

This week, host Darragh McDonald is joined by Anthony Franco of MLB Trade Rumors to discuss…

Plus, we answer your questions, including…

  • What do you think about a trade between the Tigers, who are desperate for hitting, and the Orioles, whose bullpen hasn’t been great? Detroit has a surplus of good relief pitchers, could they be trade partners? (21:05)
  • If Mason Miller were to be traded from the Athletics to another American League team and go on to win A.L. Rookie of the Year, would that team get an incentive draft pick? (26:30)
  • Say Shota Imanaga and Yoshinobu Yamamoto finish at the top of Rookie of the Year voting in the National League, will the Cubs and Dodgers get the draft compensation for having them in the majors the whole season? Considering they both signed MLB contracts, that seems antithetical to the new draft compensation for well performing rookies rule. (28:05)
  • Corbin Carroll? That’s pretty much the question: Corbin Carroll? Is there hope this season? How long can the Diamondbacks keep running him out there with no improvement in sight? I love the guy, I have as a keeper, and he was a big part of my plans for this season. Needless to say, it’s not going so well. (31:00)

D-backs, Matt Beaty Agree To Minor League Deal

By | at

The D-backs have agreed to a minor league contract with first baseman/outfielder Matt Beaty, as noted on the transaction log at MiLB.com. Beaty is now listed on the roster for Arizona’s Double-A affiliate in Amarillo.

Beaty, 31, is making his rounds through the National League West, having been drafted/developed by the Dodgers, who then traded him to the Padres in 2022. He also got into four games with the Giants last season, so the Snakes will be his fourth NL West club if he reaches the MLB level at any point.

In 675 big league plate appearances dating back to 2019, Beaty is a .247/.323/.394 hitter with 18 homers, a 16.7% strikeout rate and a 7% walk rate rate. Most of the former 12th-round pick’s production came during a 2021 showing with the Dodgers that saw him post a hearty .270/.363/.402 line in 234 trips to the plate. Beaty has struggled mightily since that time, hitting just .173/.277/.240 in a small sample of 119 plate appearances between the Padres, Giants and Royals.

In addition to last year’s sparse big league work, Beaty spent 44 games in Triple-A between Omaha (Royals) and Sacramento (Giants), slashing a combined .279/.395/.455. That level of production is par for the course for Beaty in the upper minors. He’s played in parts of five Triple-A seasons and sports a .287/.386/.421 line overall, thanks largely to excellent contact skills (15% strikeout rate) and a keen eye at the plate (9.2% walk rate).

The Diamondbacks have been one of baseball’s least-productive teams against right-handed pitching, which the left-handed-hitting Beaty handles far better than he does fellow southpaws. D-backs hitters have logged a combined .224/.308/.357 against righties, sitting 25th in the majors by measure of wRC+ (92).

Joc Pederson has absolutely feasted on right-handed pitching, while Christian Walker and Gabriel Moreno have provided strong on-base marks against right-handers. However, the D-backs have received poor production against righties from veteran Lourdes Gurriel Jr. and even more surprisingly from lefty-swinging Corbin Carroll, whose overall output at the plate this season has been shockingly anemic. Lefty bench bat Pavin Smith has struggled as well and (barring a turnaround) would seemingly be the most at risk if Beaty shows well in the minors. Any such decision is likely a ways off, however. Beaty hasn’t played yet this season — his Instagram reveals he and his wife welcomed a child midway through the offseason while he was a minor league free agent — and he will presumably need some time to ramp up before he’d even be considered a big league option.

Zack Greinke Working Out, Unsure About Continuing Playing Career

By | at

After 20 Major League seasons, Zack Grienke might not yet be ready to hang up his cleats, as the veteran right-hander has been working out at the Diamondbacks’ extended Spring Training camp.  As Nick Piecoro of the Arizona Republic writes, this isn’t any indication of a contract between Greinke and the D’Backs, as the two sides are “not believed to have had discussions about a reunion.”  Instead, the D’Backs have simply let Greinke work out at their facilities as a courtesy while he figures out the next step in his career.

That is, if there is a next step at all, since Greinke was non-committal about what these workouts exactly represent.  “I don’t know if this will be my last time throwing or if I’ll throw the rest of the year and next year,” Greinke said.  “I don’t really know at the moment….I’m just throwing, seeing how it works out and going from there.”

Greinke’s most recent two-season run in Kansas City had something of the feel of a coda on his excellent career, as Greinke returned to the franchise that drafted him sixth overall in 2002.  Greinke’s first seven MLB seasons were spent in a Royals uniform, and highlighted with a tremendous 2009 season that saw him win the AL Cy Young Award.  In between those two stints with the Royals, Greinke pitched for five other teams, and his 714 2/3 innings with the Diamondbacks from 2016-19 mark the most he has thrown for any organization outside of Kansas City.

His form from 2020-22 represented a step down from his front-of-the-rotation peak, but it wasn’t until last season at age 39 that Greinke finally had a sharp drop in performance.  The righty posted a 5.06 ERA over 142 1/3 innings, and apart from a still-elite 3.9% walk rate, it seemed as though Greinke’s recent recipe of low velocity and low strikeout totals caught up to him.

According to reports during the offseason, Greinke finished the 2023 campaign considering retirement, but as of December was preparing to pitch again.  However, Greinke told Piecoro that he had only started properly throwing two weeks ago and at the behest of his two sons, and indicated that it had been a while since he had done any winter prep work.  “My arm feels decent at the moment.  I was trying to get as good as I could at golfing the past two months, and I was like, ’Why am I trying to be a pro golfer when I’m already kind of a pro baseball player?’  So I figured I’d throw a little and see how it goes,” Greinke said.

Since the Greinke family once again lives in Arizona, the right-hander reconnected with the Diamondbacks when his sons (who are “nonstop right now” in their interest in baseball) had interest in taking part in baseball activities on a genuine Spring Training field.  This has now snowballed into Greinke’s workouts, and a recent live batting practice session against four D’Backs players on injury rehab.  Greinke faced each of Geraldo Perdomo, Alek Thomas, Jordan Lawlar and Jorge Barrosa twice during the eight at-bat session, leaving the opponents impressed.

“I told one of the guys I think he could still pitch in the majors….For his change-up to look like that in his first live BP, just imagine when he gets into a rhythm and is ready,” Perdomo said.

It seems like there’s still a ways to go before Greinke is fully set on pursuing a return, let alone signing a contract and getting properly ramped up to the point that he can again pitch in a Major League game.  “Because it’s still early” in the process, Greinke said he hasn’t talked to his agent about exploring deals with teams.  On paper, the Diamondbacks would seem a logical candidate based on familiarity and comfort alone, plus Greinke would add a lot of veteran experience to a rotation that has lost Eduardo Rodriguez and Merrill Kelly to the 60-day IL.  Another return to Kansas City shouldn’t be ruled out, even through starting pitching has been a strength for the Royals in their sudden surge into contention.
