Diamondbacks Place Eduardo Rodríguez On IL With Shoulder Inflammation
The Diamondbacks announced today that left-hander Eduardo Rodríguez has been placed on the 15-day injured list, retroactive to May 15th, with left shoulder inflammation. Lefty Joe Mantiply has also been optioned to Triple-A Reno. To take those two spots, the club has recalled right-hander Scott McGough and selected the contract of righty Christian Montes De Oca. The 40-man roster had two vacancies due to Garrett Hampson and José Castillo being designated for assignment earlier this week. Per John Gambadoro of Arizona Sports 98.7 FM Phoenix, righty Ryne Nelson will take E-Rod’s rotation spot, taking the ball on Tuesday.
There haven’t been a lot of publicly reported details about Rodríguez or his injury, but it’s possible he was feeling it last time out. He started on Wednesday against the Giants but wasn’t very effective. He allowed four earned runs in four innings and was pulled after throwing just 76 pitches. The velocity on most of his offerings was down about one mile per hour relative to his previous start. Perhaps the club will provide more information but it seems the lefty will need to miss at least a couple of starts.
That will give Nelson a chance to retake a rotation spot, at least for now. He logged 150 2/3 innings for the Snakes last year, mostly as a starter. He had a 4.24 earned run average, 20% strikeout rate and 5.4% walk rate.
Despite those strong numbers, he got pushed down the depth chart when the Snakes signed Corbin Burnes in the offseason. Burnes joined a rotation group next to Zac Gallen, Merrill Kelly, Brandon Pfaadt, Jordan Montgomery and Rodríguez. Montgomery required Tommy John surgery in March, but Nelson was still unable to get a rotation job.
He opened the year in a long relief role and has thrown 26 1/3 innings with a 5.13 ERA, but better peripherals. He has struck out 25% of batters faced while giving out walks at an 8.9% clip. A low 62.5% strand rate is not doing him favors, perhaps why his FIP is 3.71 and his SIERA at 3.45.
Kelly, Gallen and Montgomery are all free agents at the end of this year, while Burnes has an opt-out after 2026. Nelson is under club control through 2028 and could perhaps earn a long-term rotation spot with some strong results this year. Though if Rodríguez returns in relatively short order, it’s possible Nelson finds himself back in the bullpen again.
Montes De Oca, 25, gets the call to the big leagues for the first time. An international amateur signing out of the Dominican Republic, he has 181 1/3 minor league innings under his belt to this point in his career. In that time, he has a 4.17 ERA, 25.2% strikeout rate and 8.2% walk rate. He’s out to a good start this year, despite pitching in the hitter-friendly Pacific Coast League. In 19 Triple-A innings, he has a 2.37 ERA, 23.3% strikeout rate, 5.5% walk rate and 57.7% ground ball rate.

Poll: National League Playoff Outlook
We’re now a little over a quarter of the way through the 2025 regular season. With Memorial Day fast approaching, it’s hard for struggling teams to continue arguing that it’s still early. That isn’t to say playoff positions are set in stone, of course; on this day last year, the Cubs were firmly in playoff position while the Mets club that eventually made it all the way to the NLCS was still three games under .500. If the season ended today, the Dodgers, Cubs, Mets, Padres, Phillies, and Giants would be your playoff teams in the National League this year.
With four-and-a-half months left in the baseball calendar, which team currently outside of that group has the best chance of breaking their way into the mix? Yesterday’s poll covering the American League was won by the Red Sox (25%), who narrowly bested both the Rangers (20%) and Astros (20%) in a tight contest. Here’s a look at a few of NL’s the options, listed in order of record entering play today:
St. Louis Cardinals (24-20)
The Cardinals essentially left their roster untouched outside of the departure of veterans like Paul Goldschmidt and Kyle Gibson over the offseason. Right-hander Phil Maton was the club’s only major league free agent signing. Running back last year’s 83-win team without its former MVP first baseman didn’t do much for the Cardinals’ projections, but a recent nine-game win streak has allowed St. Louis to change the narrative. Willson Contreras has started hitting again, Masyn Winn could be breaking out, and Matthew Liberatore is making the decision to move him to the rotation look wise. If the Cards can keep playing anything close to this well, thoughts of selling Ryan Helsley at the deadline are likely to vanish before the calendar flips to July.
Arizona Diamondbacks (23-21)
The fourth team in a crowded four-team NL West race, the Diamondbacks have held their own this year despite injuries plaguing superstar Ketel Marte and the loss of A.J. Puk from an already-leaky bullpen. Corbin Burnes has delivered a sub-3.00 ERA despite shaky peripherals, Merrill Kelly and Brandon Pfaadt look like solid mid-rotation pieces, and Corbin Carroll is a superstar. If Zac Gallen (4.59 ERA) and Eduardo Rodriguez (7.07 ERA) can even pitch close to their respective 3.91 FIP and 4.30 FIP marks, Arizona should be a real threat to reach the postseason.
Atlanta Braves (22-22)
That Atlanta finds itself even in this conversation after going 0-7 to start the year is an impressive feat. The tandem of Sean Murphy and Drake Baldwin behind the plate has been a sensational one, and AJ Smith-Shawver is turning into a potential front-of-the-rotation surprise alongside Chris Sale and Spencer Schwellenbach. With a .500 record despite getting just one start from Spencer Strider and zero plate appearances from Ronald Acuna Jr. so far, it’s not hard to imagine the Braves fighting their way into the playoffs by season’s end. For that to happen, players like Matt Olson and Ozzie Albies will need to start hitting while closer Raisel Iglesias (5.71 ERA) will need to turn things around or be replaced by someone who can more consistently nail down save opportunities.
Milwaukee Brewers (21-23)
Disappointing performances from Christian Yelich, William Contreras, and Jackson Chourio to this point in the year have limited the Brewers’ performance so far. (Contreras is playing through a broken middle finger, which can’t help.) Thankfully, players like Rhys Hoskins and Brice Turang have both looked excellent so far and the Brewers have proved they can win mostly on the strength of their pitching before. Freddy Peralta and rookie Chad Patrick have been excellent, Brandon Woodruff is nearing a return, and top prospect Jacob Misiorowski is throwing 103 mph with dazzling results at Triple-A. If the star hitters can perform at a higher level going forward, perhaps that would be enough to get them back into the mix.
Cincinnati Reds (21-24)
It’s been a frustrating season for the Reds so far. The rotation, led by Hunter Greene and Andrew Abbott, has been strong, but those contributions have been dampened by a frustrating lineup that has failed to get consistent quality production out of anyone but Jose Trevino and Gavin Lux. Even Elly De La Cruz has been a roughly average hitter overall, while key pieces like Matt McLain and Spencer Steer have been bitterly disappointing. Fortunately, Noelvi Marte seems to be coming around after a disastrous 2024. There’s still enough time that if the club’s young lineup can go on a heater, it’s easy to imagine a strong pitching staff carrying them back into the postseason conversation.
The Rest Of The Field
The five teams mentioned above are all within five games of a Wild Card spot. The rest of the league would have a lot more work to do. The Nationals have an exciting young core featuring James Wood, CJ Abrams and MacKenzie Gore but lack the pitching depth to capitalize on it. The Marlins have gotten a big performance from Kyle Stowers, but a disappointing pitching staff that includes an 8.10 ERA from Sandy Alcantara is keeping the playoffs out of reach. The inverse is true in Pittsburgh, where Paul Skenes leads an impressive rotation but Bryan Reynolds has a wRC+ of just 55. Meanwhile, the Rockies are the team that can be most decisively counted out of the playoff picture in a season where they’re poised to contend for the modern loss record.

Diamondbacks Trade Jose Castillo To Mets
The Mets acquired lefty reliever José Castillo from the Diamondbacks for cash, the teams announced. New York designated righty Kevin Herget for assignment to create a spot on the 40-man roster. Arizona had designated Castillo for assignment on Monday.
Castillo has technically appeared in five MLB seasons, though all but eight of his appearances came with the Padres during his 2018 rookie season. He turned in a 3.29 ERA over 38 1/3 innings that year but was subsequently set back by injury.
The 29-year-old signed a minor league deal with the Snakes in November. It marked his second consecutive season in the Arizona organization. He had spent all of last year with their Triple-A team in Reno, though he lost the first half of that season to injury. The Diamondbacks assigned him back to Reno to begin this season. He struck out seven while tossing 5 1/3 innings of one-run ball and was called up at the beginning of May.
The 6’6″ southpaw only spent a couple weeks in Torey Lovullo’s bullpen. He didn’t pitch well, allowing eight runs on 10 hits (including a trio of home runs) over 6 1/3 frames. Arizona bumped him out of the bullpen when Kendall Graveman returned from injury. Castillo is out of options, so they needed to designate him for assignment to take him off the MLB roster.
That out-of-options status means the Mets are prepared to give Castillo at least some time in their big league bullpen. They’ve been forced to scour the lefty relief market after losing Danny Young and A.J. Minter to season-ending injuries. They called up Génesis Cabrera from Triple-A Syracuse. He’s the only southpaw in Carlos Mendoza’s relief corps. Cabrera has managed five innings of one-run ball over four outings, but he had walked nearly 15% of opposing hitters in Triple-A before the promotion.
The Mets will need to remove someone from the major league bullpen once Castillo reports to the team. Dedniel Núñez is the obvious candidate, since he still has a couple options remaining. Cabrera is out of options, so the Mets would need to designate him for assignment if they wanted to use Castillo as their only left-hander.
Herget relinquishes his spot on the 40-man roster. The Mets claimed the 34-year-old off waivers from Milwaukee early last offseason. He only spent one day on the MLB roster, allowing two runs on three hits in one inning. He has otherwise been working out of the bullpen at Syracuse. Herget has only allowed five runs over 15 2/3 innings, but that came with a pedestrian 13:7 strikeout-to-walk ratio. He had a much stronger 32.4% strikeout rate over 38 appearances with Milwaukee’s top farm team a year ago.
The Mets will likely place Herget on waivers within the next few days. He has been outrighted twice in his career and would have the right to elect free agency if he goes unclaimed.

Brandon Bielak Undergoes Season-Ending Shoulder Surgery
Right-hander Brandon Bielak recently underwent season-ending surgery, reports MLBTR’s Steve Adams. He’s expected to be ready for 2026 Spring Training. Bielak was released from a minor league deal with the Diamondbacks on Saturday after going on the full-season injured list last month.
The injury essentially ended Bielak’s stint with Arizona before it got off the ground. The 29-year-old signed a minor league contract with the Snakes in February. He worked 5 2/3 frames of two-run ball during Spring Training before being reassigned to the minors. Bielak started twice for Triple-A Reno. He allowed three runs across 9 2/3 innings with five strikeouts and walks apiece. Both appearances came within the first week of April. Bielak landed on the injured list on April 9 and was ruled out for the season within three days.
There’s a decent chance Bielak will spend the rest of the year as a free agent. He’ll be limited to minor league offers next winter but would again project as rotation or long relief depth if his recovery goes as expected. A former 11th-round draftee by the Astros, Bielak has spent most of his minor league career as a starting pitcher. He made 13 big league starts with Houston a couple seasons ago, though his 16 MLB appearances last year all came in relief.
Bielak divided last season between Houston and the A’s. He turned in a 5.16 ERA over 29 2/3 big league frames and a 6.08 mark across 16 Triple-A appearances. He now owns a 4.63 ERA over 204 major league innings. Bielak has a 4.37 mark over six career Triple-A seasons — a decent number for a depth starter who has spent all that time in the hitter-friendly Pacific Coast League.
Diamondbacks Designate Garrett Hampson, José Castillo For Assignment
The Diamondbacks announced that they have recalled infielder Jordan Lawlar, a move that was previously reported. They also reinstated right-hander Kendall Graveman from the injured list. To open roster spots for those two, lefty José Castillo and infielder Garrett Hampson were both designated for assignment. The club’s 40-man roster count drops to 38.
Hampson, 30, inked a minor league deal in free agency and broke camp with the D-backs after hitting .283/.393/.348 in 56 trips to the plate this spring. He hasn’t been able to carry that production over to the regular season. He’s appeared in only 18 games and taken just 41 turns at the plate, batting .167/.359/.167 in that span. He’s been a pest for opposing pitchers in the sense that he’s taken 10 walks, but Hampson is also 5-for-30 (all singles) and has bottom-of-the-scale contact metrics when he’s put the ball in play.
Arizona is Hampson’s fourth team in four seasons. He spent the first five seasons of his career with the Rockies but since his final season there has had one-year stints with the Marlins, Royals and now D-backs. He hasn’t hit much in any of those spots, combining for a .237/.308/.323 slash in 750 plate appearances dating back to 2022. However, Hamspon is a plus runner (84th percentile sprint speed, per Statcast) who can be deployed virtually anywhere on the diamond. Even though he’s been seldom used with the D-backs, he’s still seen time at five positions: second base, shortstop, third base, left field and center field.
Castillo, 29, has spent the better part of the past half decade in injury rehab. Since a strong MLB debut with the 2018 Padres, the southpaw has been on the injured list due to a torn ligament in his pitching hand, a torn lat and Tommy John surgery. Just making it back to the majors in the wake of so many rapid-fire injuries is a feat, but Castillo’s brief time with the Snakes didn’t go well. He pitched 6 1/3 innings out of Torey Lovullo’s bullpen — already his most in a big league season since ’18 — and was pounded for eight runs on 10 hits and three walks with three strikeouts.
As a rookie, Castillo fired 38 1/3 innings of 3.29 ERA ball for the Friars, fanning a gaudy 34.7% of his opponents against an 8.1% walk rate. He was terrific in a small 5 1/3-inning sample in Triple-A Reno this year, allowing only a run on four hits and no walks with seven strikeouts and a 58% grounder rate. That performance could lead to some interest from other teams, although Castillo’s once-95-mph heater has understandably dipped to an average of 93.3 mph in the wake of all those injuries.
Both Castillo and Hampson can spend a maximum of one week in DFA limbo. The D-backs can look to trade them during that time or simply place them on outright waivers. Since waivers take 48 hours to process, the team has up to five days to orchestrate trades of either player, should there be a market. In the event that they’re placed on waivers and go unclaimed, both players have enough major league service time to reject an outright assignment in favor of free agency.
Evan Longoria To Sign One-Day Contract, Retire As Member Of Rays
Three-time All-Star and 2008 American League Rookie of the Year Evan Longoria will sign a one-day contract to officially retire as a member of his original organization, the Rays, reports Marc Topkin of the Tampa Bay Times. He’ll be honored in a ceremony before the Rays’ game on June 7.
Longoria sat out the 2024 season and said last summer that he was not pursuing a return to playing but was also not formally filing his retirement paperwork just yet. That left the door ever so slightly cracked for one final comeback bid, but Longoria will now formally call it a career after nearly 2000 big league games and more than 8200 major league plate appearances.
Longoria, 39, was the No. 3 overall pick by the Rays out of Long Beach State back in 2006. He was in the majors less than two years later, getting his first call to the majors on April 12, 2008. He signed a six-year, $17.5MM extension just six games into his major league career. At the time, bets of that magnitude on such young and unproven players were nowhere near as commonplace as they are in today’s game.
That extension, which contained a trio of club options, was the largest deal ever guaranteed to a player with such little MLB experience at the time it was signed. Longoria wasted little time in proving it money well spent. He hit .272/.343/.531 with 27 homers, 31 doubles and a pair of triples as a rookie, making the American All-Star team just a few months into his MLB career.
From 2008-13, Longoria was on the short list of best players in MLB. Only Miguel Cabrera, Cliff Lee, Justin Verlander and Felix Hernandez generated more wins above replacement than Longoria’s 34.8 in that span, per FanGraphs. His 12th-inninng walk-off home run (video link) in the final game of the 2011 regular season wound up propelling Tampa Bay to the postseason that year, and Longoria’s celebratory trot with both arms above his head as he rounded first base is a timeless memory for Tampa Bay fans — one that the team commemorated with a statue outside of Tropicana Field.
Longoria proved such a bargain and such a critical piece to the Rays’ success that in November 2012, they extended him for a second time — this time on the first nine-figure contract in franchise history. Tampa Bay exercised all three of Longoria’s club options in one fell swoop and tacked on another six years and $100MM in new money (bringing the total guarantee to $136MM over nine seasons).
Longoria didn’t quite keep up his early career form, but in five subsequent seasons with the Rays (2013-17) after signing that second contract, he still slashed .265/.325/.457 (113 wRC+) while maintaining his brand of standout defense at the hot corner. FanGraphs (19.8 WAR) and Baseball-Reference (22 WAR) suggested he was still one of the game’s top 25 or so position players even if he wasn’t quite at the very top of the sport anymore.
With Longoria set to secure 10-and-5 rights early in the 2018 season — ten years of service, including five straight with the same team — the Rays made the decision to look for a trade in the 2017-18 offseason. Players with 10-and-5 rights gain full no-trade protection, and Longoria’s remaining five years and $81MM were more palatable to larger-market clubs than the cost-conscious Rays. In December 2017, the Rays lined up on a swap sending Longoria to San Francisco in exchange for outfielder Denard Span, infielder Christian Arroyo, lefty Matt Krook and righty Stephen Woods. At the time of the swap, Arroyo was a few years removed from being a first-round pick out of high school and was considered to be a top-100 prospect on some rankings.
Longoria’s first season as a Giant was a disappointment — the least-productive of what would end up being 16 seasons in the majors. He bounced back to league-average offense with solid defense in 2019, but at that point his days of star-level output were behind him. Longoria had a down showing in 2020 and posted big rate stats in a more limited, part-time role in 2021-22. He signed a one-year deal with the Diamondbacks in 2023 and had a nice first half of the season before fading down the stretch.
That 2023 season with Arizona, during which Longoria played in the second World Series of his career, will now officially prove to be his last. He’ll walk away from the game with a career .264/.333/.471 batting line, 342 home runs (tied with Ron Santo for 108th all-time), 431 doubles (145th all-time), 26 triples, 58 stolen bases, 1017 runs scored and 1159 runs batted in (185th all-time).
Longoria made three All-Star teams, won three Gold Gloves, won a Silver Slugger and landed MVP votes in six of his 16 MLB seasons. FanGraphs pegged him at 55.2 wins above replacement, while Baseball-Reference was even more bullish, crediting him with 58.9 (133rd all-time among position players). Between his pair of extensions and that final one-year deal with the D-backs, he earned more than $148MM in a 16-year career that will garner some legitimate consideration among the electorate when his name is on the Hall of Fame ballot five years from now.
Diamondbacks To Promote Jordan Lawlar
The Diamondbacks are poised to recall top prospect Jordan Lawlar, according to a report from Nick Piecoro of the Arizona Republic. Lawlar is already on the club’s 40-man roster, so only an active roster move will be necessary to promote the former No. 6 overall pick.
The promotion is a long time coming for Lawlar, who actually made his big league debut back in 2023 with a 14-game cup of coffee in late September. He hit just .129/.206/.129 in that brief stint in the majors, though the Diamondbacks nonetheless had enough belief in their top prospect to carry him on their postseason roster that year as a pinch hitter and defensive replacement. He got only two plate appearances during that postseason run, although he did draw a walk and score a run against the Rangers in the World Series.
It seemed like a given that Lawlar would play a big role in the Diamondbacks’ 2024 plans after his debut in 2023, but things unfortunately didn’t quite work out that way as he was limited to just 23 games last year by thumb surgery and a hamstring strain. The youngster hit an astounding .367/.439/.592 in the brief period he was healthy enough to play at the Triple-A level last year, but there simply wasn’t enough time left in the calendar for Lawlar to get a promotion to the big leagues by the time he was back in game shape after those injuries.
Headed into 2025, Lawlar was once again held back from joining the big league roster. That’s in part due to the presence of clear everyday players at every position he plays (Ketel Marte at second base, Eugenio Suarez at third base, and Geraldo Perdomo at shortstop), but also an acknowledgment of Lawlar’s lost season in 2024 and the developmental hurdles associated with that.
After Lawlar lost nearly an entire year of reps, Arizona brass appeared to be concerned about the impact a part-time role in the majors would have on his development. Lawlar has forced the issue across 37 games at Triple-A so far, however, with a .336/.419/.579 slash line in 179 plate appearances. Lawlar’s knocking on the door has evidently become impossible to ignore, and the Diamondbacks will now need a find a way to work all four of those infielders, first baseman Josh Naylor, and DH Pavin Smith into the lineup on a regular basis.
Piecoro notes that manager Torey Lovullo said he believes that if Lawlar could get into four games per week while mixing and matching positions, then that would be enough playing time for him to stay fresh and avoid falling behind on his development.
Removing any of Suarez (117 wRC+), Marte, (154 wRC+), Smith (175 wRC+), Naylor (125 wRC+), or Perdomo (138 wRC+) from the lineup for even a day is a not insignificant hit to the Diamondbacks’ offense, though of course Lawlar’s own contributions as a consensus top-30 prospect in the sport for a fourth consecutive season could help to balance out those losses. Smith typically only plays against right-handed pitching, so Lawlar could slide into the DH slot against lefties fairly seamlessly. The other four are all everyday players, but theoretically each could sit just once a week with Smith covering first base when Naylor is sitting so Lawlar can DH and Lawlar filling in around the rest of the infield.
An arrangement along those lines would likely keep veteran players like Suarez and Marte fresher, allow each of the club’s regulars to stay in the lineup as much as possible, and get Lawlar plenty of exposure to big league pitching as he works to establish himself at the big league level. Speculatively speaking, if Lawlar takes to the majors well, the D-backs could look into moving someone like Suarez (a pending free agent after this season) at the trade deadline to open up a more regular role for the youngster while bolstering a bullpen that has lost both A.J. Puk and Justin Martinez to the injured list. Injuries can always open up other avenues to at-bats.
For now the 21-20 Diamondbacks need to dig themselves out of fourth place in the NL West and put themselves ahead of teams like the Cardinals and Phillies in the NL Wild Card race. They’ll hope that Lawlar, still just 22, can provide a spark. He’s hit at an above-average clip at every level of the minors while showing off effective defense all around the infield. He’s also an excellent baserunner, having swiped 39 bags in 2022 and 36 the following year. This season, he’s already gone 13-for-14 on the bases in just 37 games. Lawlar is the sort of dynamic, all-around player who can help virtually any team, even one that already boasts a top-seven offense in the majors like the Diamondbacks.
Diamondbacks, Michael Perez Agree To Minor League Deal
The D-backs have agreed to a minor league contract with free agent catcher Michael Perez, per their transaction log at MLB.com. He’s been assigned to Triple-A Reno.
Perez, 32, has played in parts of six big league seasons, splitting time with the Rays, Pirates and Mets from 2018-23 and accruing more than three years of service time along the way. He’s a career .179/.248/.306 hitter in 599 major league plate appearances but draws strong defensive ratings, particularly when it comes to his ability to block balls in the dirt and control the running game (28.7% caught-stealing rate).
Though he hasn’t appeared in the majors with Arizona, Perez is signing on for his second stint with the D-backs organization. He appeared in 24 games for Reno last year as well. The lefty-hitting backstop split the 2024 season between the Triple-A affiliates for the D-backs, Orioles and Mariners, batting a combined .259/.354/.453 in 246 plate appearances. He’s a lifetime .246/.336/.424 hitter in 272 Triple-A games.
The Diamondbacks haven’t gotten much production out of Gabriel Moreno and Jose Herrera behind the plate this year — their combined .215/.291/.273 line translates to a 61 wRC+ that ranks 27th in MLB — and they’ve been without prospect Adrian Del Castillo all season due to a shoulder injury. He’s on the minor league injured list. Glove-first veterans Rene Pinto and Aramis Garcia have both hit well in Reno, even when adjusting for the heightened run-scoring environment there, but Perez will give them some extra depth who can also handle first base.
Corbin Burnes To Miss Next Start With Shoulder Inflammation
Diamondbacks right-hander Corbin Burnes is battling inflammation in his right shoulder, as reported by Nick Piecoro of The Arizona Republic. Piercoro adds that Arizona intends to scratch Burnes from his next start. It’s unclear whether or not he’ll ultimately require a stint on the injured list due to the issue, though Piecoro relays that manager Torey Lovullo told reporters before today’s game that they remain hopeful he’ll be back on the mound after just one missed start. The manager suggests that Burnes has been nagged by fatigue in his shoulder going back his last couple of starts, and that led to the club sending him for an MRI back in Arizona.
That MRI revealed “a little bit” of inflammation in Lovullo’s words, leading to the decision to skip the right-hander’s next start. Even as the Diamondbacks remain optimistic that Burnes will miss just one outing, the news is worrying for fans in the desert. After all, Arizona has fallen to fourth place in a hyper-competitive NL West division despite their solid enough 17-15 record. That record leaves them on the outside looking in for an NL Wild Card spot, behind the Padres, Giants, Phillies, and Reds in the standings aside from the division-leading Dodgers, Cubs, and Mets.
That lackluster pitching is a big reason for that middling record. While Arizona’s offense has been phenomenal so far, their run prevention has left something to be desired despite being a major strength on paper. The starting five’s 4.27 ERA is a bottom-ten figure in baseball this year, and Brandon Pfaadt is the only pitcher in the mix who has met expectations with a dazzling 2.78 ERA across six starts. Zac Gallen, Merrill Kelly, and especially Eduardo Rodriguez have all struggled so far this year.
Burnes, meanwhile, has a decent enough ERA of 3.58 that clocks in 18% better than league average by ERA+. That’s not quite what the Diamondbacks had in mind when they signed him to a six-year, $210MM deal over the winter, however, and his peripherals tell a more alarming story. His pedestrian 20.0% strikeout rate is the lowest of his career, and he’s paired it with a hefty 12.1% walk rate after having reliably excellent command in recent years. Burnes’s 5.08 FIP, 5.31 xERA, and 4.61 SIERA are all very worrisome, and suggest that even his mid-rotation production to this point in the year isn’t sustainable.
Perhaps this inflammation that he’s been battling is at least part of the explanation for the righty’s struggles. The 30-year-old hurler has made at least 32 starts in each of the past three seasons, and while that durability is admirable it’s the nature of pitching in this current era of baseball that hurlers need more rest than ever before as they push themselves for higher velocity and maximum spin efficiency. Perhaps this breather will be enough to calm the inflammation and get Burnes back on track, which would surely be a relief for Arizona as they fight to force their way back into the NL playoff picture after their surprising World Series run in 2023 and narrowly missing out on October last year.
Whether the inflammation forces Burnes to sit down for just one start or requires a stint on the injured list, the Diamondbacks are reasonably well-equipped to handle his absence even after losing sixth starter Jordan Montgomery to Tommy John surgery earlier this year. Ryne Nelson is in the bullpen as a long reliever but threw 68 pitches his last time out and is stretched out enough for a spot start or even to slide into the rotation longer-term as needed. He appears to be the most likely candidate to replace Burnes, though hurlers like Tommy Henry and Cristian Mena are also on the 40-man roster as potential depth options.
