Tigers Claim Carlos Hernández

By Darragh McDonald | June 16, 2025 at 2:20pm CDT

The Tigers have claimed right-hander Carlos Hernández off waivers from the Phillies, according to announcements from both clubs. Philadelphia had designated him for assignment last week. Detroit had an open 40-man roster spot due to designating righty John Brebbia for assignment yesterday. Hernández is out of options, so the Tigers will need to open an active roster spot once he reports to the club.

Hernández, 28, has big velocity but hasn’t always been able to translate it into results. After working in a swing role with the Royals from 2020 to 2022, he seemed to be breaking out as a reliever in the first half of 2023. Through August 1st of that year, he had thrown 54 innings with a 3.67 earned run average, 30.2% strikeout rate and 7.4% walk rate.

Unfortunately, he posted a 10.69 ERA in his final 16 innings that year. In 2024, he battled some shoulder soreness and spent the first two months of the season on the injured list. When he was reinstated, the Royals shuttled him to Triple-A and back. He posted a 3.30 ERA in the big leagues that year but with subpar strikeout and walk rates of 20.9% and 12.4% respectively. He also had a 5.40 ERA in his minor league work.

He came into 2025 out of options and didn’t make the Kansas City roster out of camp, which led him to the waiver wire and a claim by the Phillies. He logged 25 2/3 innings for the Phils this year with a 5.26 ERA, 18.7% strikeout rate and 10.6% walk rate. Though he hasn’t been able to execute, the stuff is enticing, with Hernández averaging just under 98 miles per hour on his fastball this year while also throwing a splitter, slider and knuckle curve.

Perhaps the Tigers feel they have a path to help him better harness that stuff. Or perhaps he’s just available when they want a fresh arm. Righty Will Vest departed yesterday’s game due to some discomfort in the pinky finger of his throwing hand, per Cody Stavenhagen of The Athletic. Perhaps he will require a stint on the injured list, opening a hole in the big league bullpen. Since the Tigers had an open 40-man spot anyway, claiming Hernández is perhaps a bit of insurance for Vest.

It’s also possible that the Tigers plan to put Hernández back on waivers shortly with the hope of passing him through unclaimed. The Tigers have the best record in baseball and therefore the final waiver priority, meaning the other clubs just passed on him. Hernández has between three and five years of big league service time, meaning he has the right to reject an outright assignment but would have to forfeit the remainder of his $1.16MM salary in order to do so. For now, he’ll report to the Tigers and try to put some good outings together for them.

Nationals Designate Juan Yepez For Assignment

By Darragh McDonald | June 16, 2025 at 1:25pm CDT

The Nationals announced a series of roster moves today. Outfielder Robert Hassell III and infielder José Tena have been optioned to Triple-A Rochester. Outfielder Daylen Lile has been recalled while third baseman Brady House has had his contract selected. Those four moves were reported yesterday. To open a 40-man spot for House, the Nats designated first baseman Juan Yepez for assignment.

Yepez, 27, first joined the Nationals via a minor league deal going into the 2024 season. He got added to the club’s roster in July and got fairly regular playing time in the second half of last year. He slashed .283/.335/.429 for a 113 wRC+ in 249 plate appearances.

Coming into 2025, the Nats made a couple of additions to the first base/designated hitter mix, acquiring Nathaniel Lowe from the Rangers and also signing free agent Josh Bell. Those moves pushed Yepez down the depth chart and he was optioned to Rochester to start the year. He has since appeared in 45 games for the Red Wings with a .199/.273/.301 line and 56 wRC+. He hasn’t been helped by a .212 batting average on balls in play but he also has only three home runs.

Yepez has some experience at other positions but is mostly just a first baseman. He hasn’t played third base since 2022 and his work in the outfield corners has been very limited. He’s not really a threat on the basepaths either. In short, he needs to hit. The fact that he hasn’t done so this year has hurt his value and bumped him off Washington’s roster. He’s also in his final option year, so he’s down to a few months where he can be easily sent to the minors.

He’s now in DFA limbo, which can last as long as a week. The waiver process takes 48 hours, so the Nats could take five days to explore trades. He’s been a roughly average big league hitter in 588 plate appearances between the Cardinals and Nationals but this year’s struggles on the farm will naturally tamp down interest.

If he is passed through outright waivers unclaimed, he will stick with the club as depth without taking up a roster spot. He won’t have the right to elect free agency since he has less than three years of service time and hasn’t been previously outrighted in his career.

Rays Acquire Forrest Whitley

By Darragh McDonald | June 16, 2025 at 1:05pm CDT

June 16: The Rays announced today that Whitley has been added to the club’s active roster with righty Mason Englert optioned to Triple-A Durham as the corresponding active roster move.

June 13: The Astros announced that they have traded right-hander Forrest Whitley to the Rays in exchange for cash considerations. Brian McTaggart of MLB.com first reported that Whitley was going to the Rays while Chandler Rome of The Athletic reported the cash return. The Rays’ 40-man roster count climbs from 38 to 39. Since Whitley is out of options, they will need to open an active roster spot once he reports to the team.

Whitley, 27, is a complete wild card at this point. Selected 17th overall in the 2016 draft, he put up huge numbers in the lower minor league levels as a teenager, working around a 50-game drug suspension going into 2018. His performance vaulted him towards the top of prospect lists. Going into 2019, Baseball America ranked him #5 overall and the top pitcher on the list.

He has hit a number of speed bumps since then, largely due to injuries. Shoulder problems seemed to hamper him in 2019, as he finished that year with a combined 7.99 earned run average across various minor league levels. The minor leagues were canceled by the pandemic in 2020. He required Tommy John surgery in March of 2021, wiping out that season and most of the following year. He got back on the mound in 2022 but showed plenty of rust, posting a 6.53 ERA over his 40 minor league innings. In 2023, a lat strain limited him to 30 minor league innings with a 5.70 ERA.

The Astros added Whitley to their 40-man roster in November of 2020, to protect him from being exposed in the Rule 5 draft. He used up three options in those 2021-23 seasons. The Astros were granted a fourth option for 2024 but the clock was ticking, so they moved him to the bullpen.

He showed some promise in that role last year. He logged 34 innings at the Triple-A level with a 2.12 ERA. His 11.6% walk rate was high but he struck out 31.5% of batters faced and got grounders at a 55% clip. He also made his major league debut, logging 3 1/3 scoreless innings.

He came into 2025 out of options and started the season on the injured list, this time due to a bone bruise in his left knee. He was reinstated from the IL on April 19th but went back on the shelf on April 27th due to a left knee sprain. He was reinstated in late May but didn’t last long before the Astros decided to give up and designated him for assignment. Around those IL stints, he has thrown 7 1/3 innings this year with ten earned runs allowed. He struck out eight opponents but gave out six walks, hit another batter and threw a wild pitch.

Whitley’s future is anyone’s guess at this point. The talent that made him the top prospect in baseball may be in there somewhere. He still averages in the upper 90s with his fastballs. But he’s now out of options and has proved so little. His major league track record consists of just 10 2/3 innings, which haven’t been especially impressive. He was good in the minors last year but has otherwise been hurt and/or ineffective.

The Rays have a strong reputation when it comes to developing pitchers, so it’s a good landing spot for him. However, they are also a contender, currently holding one of the three American League Wild Card spots. Since Whitley is out of options, he will have to produce some results in order to stick on the roster. If he does, the Rays can cheaply retain him for years to come. He came into 2025 with just six days of major league service time, meaning he can’t get to arbitration until after 2027 and isn’t slated for free agency until after the 2030 season. But as mentioned, those will be moot points if he can’t right the ship.

Yankees To Reinstate Giancarlo Stanton

By Darragh McDonald | June 16, 2025 at 1:00pm CDT

Designated hitter Giancarlo Stanton will be back in the lineup tonight, reports Andy Martino of SNY. Stanton is on the 60-day injured list, meaning he will need to retake a spot on the 40-man roster to be activated. The Yankees already have a vacancy there, so they will only need to make a corresponding active roster move in order to make this official.

Stanton, 35, will be making his season debut once tonight’s game begins. Way back in February, he reported to camp with soreness in both elbows and he has spent the past few months trying to get healthy. In March, he told Bryan Hoch of MLB.com that he had torn tendons in both elbows. He landed on the 10-day IL to start the season and the club listed his injury as elbow epicondylitis, more commonly known as “tennis elbow”. He was transferred to the 60-day IL at the start of May.

He has finally been able to ramp up in the past month or so, starting with some work with the high-velocity pitching machine and some live batting practice. He officially began a rehab assignment last week, going 3-11 plus a walk in three Double-A contests.

It seems fair to wonder what sort of production Stanton can provide at this point in his career. Though he has a lengthy track record of crushing the ball with ferocity, he’s now 35 years old and injuries have become more frequent. Though he’s largely been limited to the designated hitter slot, he still hasn’t appeared in 140 games in a season since 2018. He hasn’t hit the 115-game mark since 2021. Over the 2022-2024 seasons, he struck out in 30.5% of his plate appearances while slashing .212/.291/.454 for a 106 wRC+.

He’s now coming off yet another lengthy injury absence and it’s no guarantee that his bat will be an upgrade over what the Yankees have already had in there. Ben Rice has been getting most of the DH time this year and has a .227/.311/.460 line and 117 wRC+ so far this year. Knocking him out of that spot will have domino effects.

Moving Rice to first base isn’t really an option because Paul Goldschmidt is there and is hitting .311/.371/.455 for a 133 wRC+. Chris Kirschner of The Athletic points out that a Rice/Goldschmidt platoon would make on-paper sense but that manager Aaron Boone has ruled out such a tidy arrangement, perhaps not surprising with Goldschmidt a respected veteran making $12.5MM.

The Yanks are open to Rice getting some time behind the plate but Austin Wells is hitting .224/.288/.464 for a 107 wRC+ with solid defensive grades. He has also helped the pitching staff put up good numbers all year along despite the injuries to Gerrit Cole, Luis Gil and others. Even backup catcher J.C. Escarra has a .230/.333/.361 line and 100 wRC+ with good defense to boot.

Stanton does have some outfield work in his past but didn’t play there at all last year. Given his elbow injuries, he’s probably not going to be sent out to the grass. Even if the Yanks were willing to do that, they have been getting strong results from their outfield group of Aaron Judge, Cody Bellinger, Trent Grisham and Jasson Domínguez.

It’s technically a good problem to have but it will be tricky for Boone to get the right balance of finding playing time for everyone so they all can stay crisp while simultaneously trying to optimize the lineup for success on a given day, though the logjam probably won’t last long since injuries are fairly inevitable.

Diamondbacks Sign Anthony DeSclafani To Major League Contract

By Darragh McDonald | June 15, 2025 at 12:33pm CDT

TODAY: The D’Backs announced that DeSclafani signed a big league deal, and he has been added to the active roster.  To create roster space, right-hander Bryce Jarvis was optioned to Triple-A and Justin Martinez (who will miss the rest of the season due to UCL surgery) was shifted from the 15-day IL to the 60-day IL.

JUNE 12: Right-hander Anthony DeSclafani has opted out of his minor league deal with the Yankees and is joining the Diamondbacks, reports Joel Sherman of The New York Post. It’s unclear if he’ll be signing a major or minor league deal with Arizona.

DeSclafani, 35, signed a minor league deal with the Yankees about a month ago. He has since made five starts at the Triple-A level, allowing 4.50 earned runs per nine in his 20 innings. He struck out 22.2% of batters faced while giving out walks at a 10% clip and getting grounders on 42.4% of balls in play. All those rates are fairly close to typical big league averages.

It’s a small sample of work but DeSclafani has a lengthy major league track record. The larger question in recent years has been health, or the lack thereof. From 2015 to 2021, he posted a 3.97 ERA over 791 major league innings. That was enough to get him a three-year, $36MM deal from the Giants going into 2022.

Unfortunately, he wasn’t able to provide much return on that investment. Right ankle inflammation hobbled him throughout 2022, limiting him to five starts with a 6.63 ERA. In 2023, he logged 99 2/3 innings with a 4.88 ERA but didn’t pitch after July due to a right elbow flexor strain. He was traded to the Mariners and then the Twins ahead of the 2024 season but required season-ending flexor tendon surgery in March.

DeSclafani is now almost two years removed from his most recent major league game but appears to be healthy now. He has averaged 92.5 miles per hour on his fastball so far this year. That’s a bit down from a few years ago, as he averaged between 93 and 95 mph during his best years, but he might still be ramping up after a lengthy layoff.

Unsurprisingly, the Yankees didn’t have a fit for him at the big league level. Despite several injuries, their rotation is in decent shape. They have Max Fried, Carlos Rodón, Clarke Schmidt, Will Warren and Ryan Yarbrough. They could get Marcus Stroman and JT Brubaker back soon, as both are on rehab assignments. Luis Gil is tossing bullpens and could be on his own rehab assignment in the coming weeks.

The Diamondbacks have a shakier rotation. They recently lost Corbin Burnes to Tommy John surgery. Jordan Montgomery has been out all year due to that same procedure. That leaves them with Zac Gallen, Merrill Kelly, Brandon Pfaadt, Eduardo Rodríguez and Ryne Nelson. Kelly has been good but he’s the exception. Each of Gallen, Pfaadt and Rodríguez has an ERA north of 5.00. Rodríguez also just returned from an IL stint for shoulder inflammation. Nelson’s ERA is at 4.60 but he’s largely been in a long relief role this year. He just returned to the rotation in the wake of the Burnes injury but allowed seven runs in three innings against the Reds on Saturday. Potential replacements like Cristian Mena and Blake Walston are also on the shelf.

In short, DeSclafani has a far better chance to returning to the big leagues with the Snakes than with the Yanks, so this is a sensible move for him. If he is jumping right into the big leagues, the Diamondbacks would need to make corresponding moves to get him onto the active and 40-man rosters. If it’s a minor league deal, he’ll presumably report to Triple-A Reno to continue ramping up there.

Shaun Anderson Elects Free Agency

By Darragh McDonald | June 14, 2025 at 2:13pm CDT

TODAY: Anderson cleared waivers and elected free agency over an outright assignment to Triple-A, the Angels announced.

JUNE 13: The Angels announced today that they have selected the contract of infield prospect Christian Moore and recalled right-hander Sam Bachman. In corresponding moves, outfielder Matthew Lugo has been optioned to Triple-A Salt Lake and righty Shaun Anderson has been designated for assignment. MLBTR covered the Moore/Lugo swap yesterday. Jeff Fletcher of the Orange County Register reported today’s full slate of moves prior to the official club announcement.

Anderson, 30, has been on and off the Angels’ roster this year. He signed a minor league deal in the offseason and was called up in early May. He was designated for assignment later that month, cleared waivers, elected free agency, re-signed with the club and was added back to the roster a few days ago. Around those transactions, he has logged 10 2/3 innings over six appearances. He allowed nine earned runs on 16 hits, giving out three walks while striking out ten opponents.

Broadly speaking, Anderson has usually been able to put up decent Triple-A numbers that haven’t translated to the big leagues. He made his major league debut in 2019 and now has 162 2/3 innings under his belt with a 6.20 earned run average. In that same time frame, he has a 3.93 ERA in 307 Triple-A frames. He also spent a season in Korea and put up a 3.76 ERA there.

Since he’s out of options, he can’t be easily sent back down to the minors. The last time he lost his roster spot with the Halos, he cleared waivers and circled back to them, so it’s possible that same sequence will play out in the coming days.

White Sox Outright Bryse Wilson To Triple-A

By Darragh McDonald | June 14, 2025 at 12:54pm CDT

TODAY: Wilson cleared waivers and has been outrighted to Triple-A Charlotte, the White Sox announced.

JUNE 10: The White Sox announced that they have selected right-hander Grant Taylor to the roster, a move that was reported yesterday. Fellow righty Bryse Wilson has been designated for assignment as the corresponding move.

Wilson, 27, was signed in December to a one-year deal that guaranteed him $1.05MM. He was a sensible pickup for Chicago since he had experience as both a starter and a reliever. With the Brewers over 2023 and 2024, he tossed 181 1/3 innings with a 3.42 earned run average. The rebuilding Sox came into the year with a fairly young and inexperienced pitching staff and could deploy Wilson as needed, depending on how he and everyone else performed.

Unfortunately, he hasn’t really provided the club with much in either role. He has made five starts and 14 relief appearances so far this year, logging 45 1/3 innings with a 6.95 ERA. That includes a 6.23 ERA as a starter and a 7.61 mark in relief work. His 8.7% walk rate is right around average but his 12.4% strikeout rate is barely half of league par.

That performance has nudged Wilson off the roster and into DFA limbo, which can last for a week at most. The waiver process takes 48 hours, so the Sox can theoretically take five days to explore trade interest. However, given Wilson’s salary and performance this year, there isn’t likely to be strong interest.

If he is passed through waivers unclaimed, he will likely stick with the Sox as non-roster depth. Players with at least three years of service time have the right to reject an outright assignment and elect free agency. However, if they have less than five years of service, they have to forfeit their remaining salary in order to exercise that right.

Wilson came into this year with four years and 36 days of service. By my count, he has added 75 days so far in 2025, putting him at 4.111. That’s still 61 days shy of the five-year mark. Assuming he wants to keep the rest of that $1.05MM flowing, he would choose to report to Charlotte as opposed to electing free agency.

The Sox are 22-44 this year and will clearly be deadline sellers. Any pitcher with limited control who is putting up decent numbers should be available in the coming weeks. That includes guys like Adrian Houser, Dan Altavilla and Steven Wilson. That could further thin out the pitching staff and open further opportunities for Bryse later in the year.

Pirates Claim Michael Darrell-Hicks

By Darragh McDonald | June 14, 2025 at 12:18pm CDT

TODAY: After a consultation with Dr. Neal ElAttrache, Rodriguez will get a PRP injection next week and then be shut down for the next four weeks, Pirates manager Don Kelly told reporters (including MLB.com’s Alex Stumpf).

JUNE 13: The Pirates announced that they have claimed right-hander Michael Darrell-Hicks off waivers from the Angels and optioned him to Triple-A Indianapolis. He had been designated for assignment by the Halos a few days ago. To open a spot on the 40-man roster, catcher Endy Rodríguez has been transferred to the 60-day injured list.

Darrell-Hicks, 27, was an undrafted free agent signing from 2022. The Angels moved him from a starting role to the bullpen going into the 2024 season. He logged 62 1/3 innings combined between Double-A and Triple-A last year, allowing 2.60 earned runs per nine. He struck out 26.4% of batters faced, limited walks to a 5% clip and got grounders on 48.8% of balls in play. FanGraphs ranked him as the #21 prospect in the system going into this year.

The Angels added him to their roster in early April and he has been shuttled between Triple-A and the majors since then. In his 7 2/3 big league innings, he has allowed eight earned runs while striking out six and giving out four walks. In his 22 1/3 Triple-A innings, he has an 8.87 ERA but a lot of that is likely luck, as his .386 batting average on balls in play and 59.5% strand rate are both on the unfortunate side. His 21.3% strikeout rate, 7.4% walk rate and 46.7% ground ball rate are all decent numbers.

He still has a full slate of options and just a handful of service days, so he can potentially be a long-term depth arm for the Pirates if he continues to hang onto his 40-man roster spot. For now, he’ll head to Indianapolis and await his next big league opportunity.

As for Rodríguez, his status isn’t clear but the transfer to the 60-day IL is a bit ominous. He was only placed on the 10-day IL a few days ago due to right elbow inflammation. Based on today’s move, the Bucs don’t expect him back until August at the earliest. He missed the entire 2024 season due to UCL surgery on that elbow.

More information should be forthcoming on his status in the coming days or weeks. For the time being, he won’t factor into the club’s catching mix. Henry Davis and Brett Sullivan are the active backstops. Joey Bart is on the concussion-related IL but should be back in the mix soon since he has already begun a rehab assignment.

White Sox, Brewers Swap Aaron Civale, Andrew Vaughn

By Darragh McDonald and Nick Deeds | June 13, 2025 at 11:57pm CDT

The White Sox acquired right-hander Aaron Civale and cash considerations from Milwaukee for first baseman Andrew Vaughn. The Brewers optioned Vaughn to Triple-A Nashville, while Civale will step directly into Chicago’s rotation. The Brewers are reportedly sending cash to offset the difference in remaining salary between Civale’s $8MM sum and Vaughn’s $5.85MM figure.

It’s a quick turnaround after Civale requested a trade away from Milwaukee on Thursday. Civale’s trade request came on the heels of the club’s decision earlier this week to bump him from the rotation in order to call up top pitching prospect Jacob Misiorowski. Civale, a free agent after the 2025 campaign who struggled a bit last year but has pitched to a 3.32 ERA and 3.92 FIP in four starts since returning from the injured list last month, evidently wants to hold onto a rotation job to set himself up for success in free agency this winter as much as possible.

The 30-year-old’s wish was promptly granted, as he’s now headed for the White Sox. The South Siders have no real hope of competing for a playoff spot this year, but with a patchwork rotation that features multiple Rule 5 draftees it’s not hard to see Civale as a potentially substantial upgrade for their starting rotation. While a team headed for their second-consecutive 100-loss campaign acquiring a rental starting pitcher in the middle of the season is a rare occurrence, one can see the logic from Chicago’s perspective given that they’ll have the opportunity to flip Civale to a club with postseason aspirations closer to the trade deadline.

The logic is particularly sound for the White Sox given the player they’re giving up in return. Vaughn was the third-overall pick in the 2019 draft and a longtime top 100 prospect, but his major league career has been a disappointment so far. He entered the 2025 season with a career .253/.310/.415 (102 wRC+) slash line at the major league level and has had just one season where he had hit at a clip substantially better than league average. Things took a more pronounced nosedive this year, as he’s slashed just .189/.218/.314 (44 wRC+) across 48 games for the White Sox in 2025. It’s the lowest on-base percentage of any player with at least 120 plate appearances in the majors this year, and his -1.3 fWAR this season is dead last among all hitters who have stepped up to the plate in the majors this season. The Sox optioned him to Triple-A Charlotte a few weeks ago and he has hit .211/.328/.351 in 15 games for the Knights since then.

That’s not a player the White Sox could expect to get a substantial prospect return for this summer, and while Vaughn has one year of control remaining after this one he currently has the look of a clear non-tender candidate. That surely made the opportunity to roll the dice on flipping a veteran starting pitcher a very attractive option for Chicago.

With all that being said, it’s not as though the deal doesn’t make sense for the Brewers. Civale no longer fit in an increasingly deep Brewers rotation mix, and his roster spot is likely better used on other arms more suited for bullpen duty than a veteran starter with zero career relief appearances. What’s more, Vaughn’s underlying numbers paint the picture of a player whose actual performance isn’t all that different from his previous seasons as a league average hitter. While he’s walking at a career-low 3.6% clip, he was never an especially patient hitter. His 22.3% strikeout rate is only a tick higher than last year, and his 13.3% barrel rate this season is actually the best of his career and four points better than last season. Vaughn’s ghastly .217 BABIP should improve with time, and with incumbent first baseman Rhys Hoskins likely ticketed for free agency this winter getting Vaughn on board as a much cheaper possible replacement makes sense.

In the shorter term, Vaughn will serve as minor league depth. The Brewers reportedly view him as a full-time first baseman/DH even though he has experience in the outfield.

Jon Heyman of The New York Post first reported that Milwaukee was trading Civale to the White Sox. Jesse Rogers of ESPN reported that Vaughn was headed back to the Brewers. Adam McCalvy of MLB.com reported the cash exchange.

By Darragh McDonald | June 13, 2025 at 5:20pm CDT

Diamondbacks right-hander Justin Martínez will undergo Tommy John surgery. Arizona manager Torey Lovullo relayed the info today, per John Gambadoro of Arizona Sports 98.7 FM Phoenix. He’ll miss the remainder of this season and a decent chunk of 2026 as well. He is already on the 15-day injured list but will be transferred to the 60-day IL once the club needs to open a roster spot.

The news is devastating but not especially surprising. Earlier this week, Martínez landed on the IL and the Diamondbacks announced his injury as a sprain of his right ulnar collateral ligament. A sprain, by definition, involves some degree of stretching or tearing. Not all UCL sprains lead to surgery but many do.

Now that Martínez will go under the knife, he’ll be out of action for a long time. The surgery usually takes 14 to 18 months of recovery, so he’ll certainly out for the rest of this season. A return in the second half of 2026 is possible but not a guarantee.

That’s a huge blow for the Arizona bullpen. Martínez broke out last year with 72 2/3 innings with a 2.48 earned run average. His 11.7% walk rate was a bit high but he punched out 29.5% of batters faced and got opponents to pound 58.9% of balls in play into the ground.

Coming into 2025, he and A.J. Puk were supposed to be the anchors of the bullpen. The Snakes even gave Martínez a five-year, $18MM extension to cement him as part of the long-term plans. But Martínez has been on and off the IL this year, first due to shoulder inflammation and now this UCL injury. Puk has also been on the IL for almost two months now due to elbow inflammation.

Naturally, missing those two has hampered the bullpen. Arizona relievers have a collective 5.21 ERA this year, which is better than just the Angels, Nationals and Athletics. The club is 34-34 on the year, 4.5 games back of a playoff spot. Puk could be back at some point later in the year but they will have to try to survive without Martínez. If they hang in the race long enough to be buyers, then adding bullpen help at the deadline would make plenty of sense.

For the team, there is one silver lining. The extension they signed with Martínez contained two club options for 2030 and 2031, followed by a conditional club option for 2032. That conditional option would be worth $3MM and would be unlocked if Martínez required elbow surgery or spent a certain number of days on the injured list during the course of the deal. Now that he is going under the knife, that option will be officially available to them.

That’s assuming Martínez can get back on the mound and return to his previous form, which would prompt the Snakes to pick up those club options. Though Tommy John surgeries are quite common, not all pitchers can get 100% effectiveness back afterwards. Martínez is also undergoing the procedure for a second time, which adds to the risk. He first went under the knife as a prospect in 2021.
