Diamondbacks Rumors

Diamondbacks Place Justin Martinez On 15-Day IL, Transfer A.J. Puk To 60-Day IL

By | at

The D-backs announced Thursday that they’ve placed closer Justin Martinez on the 15-day injured list due to right shoulder inflammation. Lefty Jose Castillo’s contract was selected from Triple-A Reno to take his spot on the active roster. Fellow southpaw A.J. Puk moves from the 15-day IL to the 60-day IL to create 40-man roster space for Castillo.

Martinez was set for an MRI this morning after experiencing an alarming velocity drop over the past week. He’s gone from averaging triple digits on his power sinker to sitting just 93.5 mph in his most recent appearance. Though the right-hander claimed he felt 100% healthy, he’ll head to the injured list with a still-vague injury designation. The D-backs will surely provide more information on his status and potential timeline later today.

This slate of injury-related moves is a brutal blow for a D-backs team that spent much of the offseason looking for established bullpen arms but wound up making generally smaller-scale moves. Martinez and Puk are the team’s two best relievers and entered the year as the favorites to work in save and high-leverage hold situations. They’re both on the shelf, and while Puk’s flexor strain won’t require surgery, today’s move to the 60-day IL only further underlines the fact that Arizona is going to be without him for quite some time.

Martinez, 23, averaged 100.2 mph on his sinker in 2024 and averaged better than 100 mph on the pitch in each of his first eight appearances this year. A dip into the 97-99 mph range over his next three outings was concerning but not necessarily cause for full-fledged alarm. Last night’s drop all the way to 93.5 mph, in an outing where he faced three hitters and allowed two walks and a home run, is another story entirely.

It’s become an ominous situation for D-backs fans to monitor, and one that’s compounded by Puk’s absence. Martinez broke out with a 2.48 ERA, 29.5% strikeout rate, 11.7% walk rate, 58.9% ground-ball rate, eight saves and seven holds across 72 2/3 innings for the Snakes last year. He clearly has some command issues, but the elite velocity coupled with plus strikeout and ground-ball rates helped to mitigate that bloated walk rate.

The D-backs, clearly bullish on Martinez’s future, signed him to a five-year, $18MM extension during spring training. The contract contains a pair of club options for the 2030-31 seasons, which would’ve been Martinez’s first two free agent years. At the time, there was little reason to fear an injury (beyond the general attrition rate of pitchers in today’s game). Now, the outlook is far hazier.

Were Puk healthy, the Diamondbacks would surely have just plugged him into the closer’s role and moved forward with Kevin Ginkel setting up. But Puk hit the injured list with elbow inflammation after a strong eight-inning start to his 2025 season, and a subsequent MRI revealed a flexor strain that’ll require a notable shutdown period.

With Martinez and Puk both shelved, the D-backs will likely turn closing duties over to a combination of Ginkel and Shelby Miller, who returned to Arizona on a minor league deal this offseason and has been outstanding after earning a job this spring. Ginkel only just returned from his own bout of shoulder inflammation, which sidelined him for the first month of the season. From 2022-24, he pitched a combined 164 2/3 innings with a 2.95 ERA, 26.1% strikeout rate and 7.9% walk rate. Miller has pitched 12 2/3 scoreless innings in his return to Phoenix, punching out a gaudy 31.9% of opponents against an 8.5% walk rate.

The 29-year-old Castillo isn’t likely to replicate the type of results that could’ve been expected from either Martinez or Puk, but he’s a reasonably experienced southpaw who’s had some prior success in the majors. Back in 2018-19, the southpaw looked to be breaking out as a viable bullpen arm for the division-rival Padres, pitching to a combined 3.23 ERA with a 35% strikeout rate and 8.4% walk rate in his first 39 big league innings.

Injuries have blown up Castillo’s career since. He suffered a torn ligament in his hand that cut his 2019 season short. A torn lat wiped out his 2020 season. He underwent Tommy John surgery in 2021 and missed most of the 2022 season as a result. It’s a staggering run of unfortunate maladies for the southpaw, but he’s shown some encouraging signs since joining the D-backs on a minor league deal last year.

In 24 innings between Arizona’s Rookie-ball and Triple-A affiliates last year, Castillo notched a 3.75 ERA. He whiffed 24.1% of his opponents and issued walks at an 8.1% clip with Triple-A Reno. This year, he’s started out by holding opponents to a run on four hits and no walks with seven strikeouts in 5 1/3 frames. Castillo has had an arduous grind to get back to the majors after pitching just two MLB frames from 2019-23. He’s now poised for his first real look in a bullpen since 2018, despite accumulating four years of MLB service time through his various stints on the 60-day injured list.

Because he only has four years of service, Castillo could be a multi-year option for Arizona if he can get back to his early career form. Enough time has already elapsed that he won’t be able to reach five years of service before the conclusion of the 2025 season. That means even if he’s back in the majors for good — and that’s far, far from certain — he can be controlled through the 2027 campaign via arbitration.

A.J. Puk Shut Down With Flexor Strain, Not Expected To Require Surgery

By | at

D-Backs southpaw A.J. Puk has been diagnosed with a flexor strain, reports Nick Piecoro of The Arizona Republic. He’ll remain shut down from throwing for 2-3 weeks before going for reevaluation. Fortunately, the team does not believe the injury will require surgery.

It’s moderately encouraging news after last week’s revelation that Puk was seeking multiple opinions on his elbow injury. He went on the 15-day injured list on April 19 and almost immediately went for imaging. That obviously raised the possibility of surgery, but it seems he’ll avoid the worst-case scenario.

That said, he’s clearly going to be out for an extended stretch. Puk will not resume throwing until the middle of May at the earliest. He’ll surely require a multi-week build from there. He won’t be back on an MLB mound before June, and there’d seem to be a decent chance he’s out beyond the All-Star Break. Puk has a previous Tommy John procedure on his medical chart. He underwent the surgery while he was a prospect in the A’s system back in 2018.

Acquired from Miami at last year’s deadline, Puk has been brilliant for the Diamondbacks. He posted a 1.32 ERA with 43 strikeouts in just 27 1/3 innings down the stretch. He’d reeled off another eight frames of three-run ball with 12 punchouts this season. He recorded four saves and two holds without surrendering a lead over the first three weeks.

Puk’s absence puts greater pressure on Justin Martinez to cement himself as Torey Lovullo’s top late-game weapon. The fireballer has worked 10 innings of two-run ball with 11 punchouts and a massive 61.9% grounder rate. Shelby Miller, Kevin Ginkel, Jalen Beeks and Ryan Thompson are among the setup group.

Diamondbacks Notes: Lawlar, Marte, Infield

By | at

Diamondbacks prospect Jordan Lawlar is doing everything he can to push for a major league promotion, as he’s currently mashing in Triple-A. Assuming he eventually cements himself in the majors, the question will be what position he plays.

He came up as a shortstop prospect but the Diamondbacks don’t have much need at that position. Geraldo Perdomo took over regular shortstop duties in 2022. The Diamondbacks are evidently pleased with him there as they recently signed him to an extension that runs through 2029 with a club option for 2030. They could move Perdomo to second or third base, where he has some experience. However, his bat has only been around league average in recent years, as his speed and defense at short are his primary ways of providing value.

That has made it seem like Lawlar would eventually move to second or third. He has always had tremendous offensive numbers in the minors, so his bat should play elsewhere. The Snakes have had Ketel Marte as their regular second baseman for years and he’s signed well into the future as well, which seemingly made third base Lawlar’s best path. However, Bob Nightengale of USA Today says that some scouts think Lawlar will take over at second and bump Marte to first.

There hasn’t been any reporting to suggest that the Snakes do plan on moving Marte to first, but perhaps their usage of Lawlar this year is a tell. With Triple-A Reno, he has 123 innings at second base so far. He has just 36 innings at third base this year and just 95 in his entire minor league career. He has hundreds of innings at shortstop over the years but just 54 in 2025.

It would be an interesting pivot if the club is making it. The Diamondbacks acquired Eugenio Suárez ahead of 2024 to cover the third base position. He was going into the final season of his contract, so it seemed possible that he was simply a stopgap until Lawlar was ready. Suárez struggled badly in the first half of last year but Lawlar spent most of 2024 injured, dealing with thumb and hamstring injuries. He only got into 23 minor league games last year, giving Suárez a chance to get back on track. Suárez destroyed baseballs enough in the second half that the club picked up their $15MM option on him for 2025, instead of going for the $2MM buyout.

Coming into 2025, it was still fair to expect that Suárez would eventually give way to Lawlar. Suárez turns 34 in July and will be a free agent at season’s end. That could still be the plan but the fact that Lawlar is playing a lot of second base is interesting. Marte has had some injury absences in his career and is currently on the injured list with a hamstring strain. He is 31 years old and the club recently extended him through 2031, which would be his age-37 season. Perhaps they believe that moving him to first base would be the best thing for his long-term health.

Right now, Josh Naylor and Pavin Smith are sharing first base and designated hitter duties. Naylor is an impending free agent, so that could provide an opening for Marte to slide into as soon as next year.

This is all still fairly speculative but it’s a notable position for the Snakes to be in. It’s possible that they are simply moving Lawlar around to different positions, experimenting to see how things go. If he seems viable at multiple spots, that will give them more choice for how to proceed next offseason, with both first and third base set to be vacated going into the winter. Another factor could be that LuJames Groover is also one of the club’s top ten prospects and is currently hitting well at Double-A while playing third base regularly.

However it plays out defensively, Lawlar is generating a lot of excitement with his bat. He’s currently sporting a line of .356/.451/.644 with Reno this year. He won’t be able to maintain a .457 batting average on balls in play forever but he has five home runs and a 13% walk rate. He also has 12 stolen bases in 13 attempts through 26 games.

Phillies, Diamondbacks Interested In Ryan Helsley

By | at

The calendar has not yet even flipped to May, leaving more than three months to go until MLB’s trade deadline on July 31. That hasn’t stopped some teams from assessing their needs and even beginning to look into potential targets for the summer, however, and USA Today’s Bob Nightengale writes that the Phillies and Diamondbacks both already have an eye on Cardinals closer Ryan Helsley. There’s no indications that St. Louis is currently listening to offers on their closer, nor that either Philadelphia or Arizona has reached out to Cardinals brass at this point, though Nightengale goes on to suggest that Helsley is “likely” to be dealt prior to the deadline.

It’s easy to see why Helsley would be an attractive candidate for teams looking for a closer. The righty emerged as the Cardinals’ closer in 2022 and has been nothing short of dominant ever since, with a combined 1.83 ERA (225 ERA+), a 34.6% strikeout rate, and and 2.35 FIP to go with 83 saves over the past three years. Those numbers are nothing short of elite: Among all qualified relievers during that stretch, Helsley’s ERA is third (behind Emmanuel Clase and Devin Williams), his FIP is fourth (behind Williams, Matt Brash, and Edwin Diaz), his saves total ranks sixth, and his strikeout rate ranks eighth.

Those sensational numbers made Helsely a prime trade target for clubs in need of relief help over the winter, including Arizona and Toronto. The Cardinals seemingly rebuffed offers on their closer throughout the offseason, however, even as they opted not to discuss an extension with their closer as they shied away from making long-term commitments this winter. St. Louis’s 12-15 record puts them 4.5 games back of the Cubs in the NL Central and three games underwater. It’s still plenty early enough for virtually any team in the majors to go on a run and get themselves into the playoff conversation, but failing a surprise reversal in fortune a Cardinals front office that attempted to soft-launch a retooling over the offseason appears likely to sell rental pieces like Helsley this summer.

Should Helsley be dangled by the Cardinals later this year, they’ll surely find plenty of suitors. Toronto pivoted to sign Jeff Hoffman after they failed to land Helsley, and that decision is going swimmingly so far. The Diamondbacks did not find a closer over the offseason, however, so Nightengale’s report that they have continued interest in Helsley makes plenty of sense. That’s particularly true after A.J. Puk was shelved last week due to elbow inflammation that seems likely to keep him out of action for the foreseeable future, further denting a bullpen that relied primarily on Puk and Justin Martinez to close out games.

The Phillies, meanwhile, attempted to address the losses of Hoffman and Estevez in free agency by signing non-tendered Jays closer Jordan Romano. The 32-year-old had been one of the league’s top closing pitchers not long ago, with a 2.29 ERA and two All-Star appearances between 2020 and 2023. Things changed last year, however, as Romano battled elbow inflammation and pitched to an ugly 6.59 ERA in the 15 appearances he did make. That led the Jays to non-tender Romano, and the Phillies eventually snapped him up on an $8.5MM guarantee. That deal was signed with the idea that Romano would join lefties Jose Alvarado and Matt Strahm in the late innings for the Phillies this year, but things haven’t gone to plan as he’s allowed a whopping 15 runs (14 earned) in just 9 1/3 innings of work over 11 appearances.

It’s hardly a shock that such an ugly performance has inspired the Phillies to begin surveying closing possibilities on the trade market. The club’s core is continuing to age and with players like Ranger Suarez, Kyle Schwarber, and J.T. Realmuto set to hit free agency this winter the team could look extremely different this time next year. If 2025 proves to be the Phillies’ last opportunity to win with their current core, it would make sense to be aggressive in supplementing it this summer even as they enter play today with a relatively pedestrian 14-13 record. Adding a solid back-end reliever like Helsley, as they did when they dealt for Estevez last year, could go a long way to helping Philadelphia gear up for a playoff run in what looks to be an extremely competitive National League this year.

As sensible as the addition of a player like Helsley may be, Nightengale is quick to note that the Phillies aren’t interested in trading their very best and most impactful prospects. Specifically Nightengale writes that both Andrew Painter and Aidan Miller won’t be included in any trade, and that’s hardly a surprise given that both are well-regarded pieces with high ceilings who are already in the upper levels of the minors. It would be a shock if either of them were traded this summer and it’s almost unfathomable that either could ever be considered in a deal for a rental relief arm, even one as electric as Helsley.

Diamondbacks Select Scott McGough

By | at

The Diamondbacks announced a series of roster moves this afternoon, headlined by them selecting the contract of right-hander Scott McGough. Right-hander Yilber Diaz was optioned to the minors in a corresponding move, and righty J.P. Feyereisen was designated for assignment to make room for McGough on the 40-man roster.

McGough, 35, was a fifth-round pick by the Dodgers in 2011 who debuted in the majors with the Marlins back in 2015. He made just six appearances for Miami before spending the following years bouncing around the minor leagues with Colorado and Baltimore until he departed stateside ball entirely ahead of his age-29 season to pitch for Nippon Professional Baseball’s Yakult Swallows. He put together a very impressive resume in four seasons as the Swallows’ closer, with a 2.94 ERA in 232 2/3 innings of work and a 26.0% strikeout rate.

That performance was enough to get him stateside attention from Arizona, and McGough departed Japan to sign with the Diamondbacks prior to the 2023 season for $6.25MM guaranteed over two years. That decision proved to be a mistake for the Snakes. McGough was a below average but relatively passable middle reliever for Arizona in his first year with the club, posting a 4.73 ERA (93 ERA+) and a matching 4.76 FIP across 70 1/3 innings of work for the team. While he struck out a solid 25.6% of his opponents, McGough was held back by a 10% walk rate and troubles with the long ball as a whopping 24.6% of his fly balls left the yard for home runs.

That poor fortune led to some advanced metrics like his 3.49 SIERA pointing to better days ahead, but things got even worse in 2024 when his peripherals collapsed across the board. The righty’s age-34 season saw him post a 16.7% strikeout rate against a 14% walk rate, leaving him with a ghastly 7.44 ERA and a 6.04 FIP across his 26 appearances. The Diamondbacks made the easy decision to decline a 2025 club option on his services last winter, though they eventually re-signed him to a minor league deal in April. Now, he’ll be tabbed to help eat innings for a Diamondbacks bullpen that has surrendered a 4.69 ERA and recently lost one of its top relievers, A.J. Puk, to the injured list.

Making room for McGough on the 40-man roster is Feyereisen, who has been at Triple-A with the Diamondbacks after surrendering three runs (two earned) on three hits in two innings of work. The move comes as something of a surprise given his dominance at Triple-A Reno, where he’s posted a 0.96 ERA in 9 1/3 innings of work. That work came with just a 17.9% strikeout rate, however, and Feyereisen was torched for an 8.18 ERA in ten appearances with the Dodgers at the big league level just last year. The 32-year-old has been struggling to get back into a regular role in the majors ever since he underwent shoulder surgery with the Rays back in 2022 and has just 13 innings of work in the majors in the years since then. The Diamondbacks will have one week to either trade Feyereisen or attempt to pass him through waivers, at which point he’ll be able to either accept an outright assignment or reject it in favor of free agency should he not get claimed by a rival club before then.

The D-backs’ Late-Blooming Slugger

By | at

The D-backs moved on from Joc Pederson this past offseason, bidding farewell to a slugger who made 132 appearances at designated hitter for them in 2024 and turned in an outstanding .275/.393/.515 slash in 449 plate appearances. Pederson was limited to 42 plate appearances against left-handed pitching but was a mainstay in the lineup against right-handed opponents. He torched righties at a .281/.392/.531 clip -- 54% better than league average, by measure of wRC+.

Arizona spent more than anyone expected this past offseason, but the vast majority of that spending came in the form of their stunning six-year, $210MM signing of right-hander Corbin Burnes. That marked the largest contract in franchise history, helping push payroll to record levels. The rest of the front office's moves were understandably on the smaller side, at least in terms of financial commitment. A trade for Josh Naylor replaced Christian Walker at first base for about half the 2025 price (and one-sixth of the overall financial commitment). Re-signing Randal Grichuk cost another $5MM. Relievers Kendall Graveman and Jalen Beeks signed for under $2MM apiece.

Pederson's two-year, $37MM deal with the Rangers was announced on the same day as Burnes' deal with the Diamondbacks. Based on the totality of Arizona's offseason, it'd be fair to presume that signing both simply wasn't in the budget. Perhaps, however, the D-backs felt comfortable moving on from Pederson because they bought into the out-of-the-blue breakout from another lefty slugger on the roster.

Diamondbacks Release Grae Kessinger

By | at

The Diamondbacks have released infielder Grae Kessinger, according to his transactions tracker at MLB.com. He was already off the 40-man roster, having been designated for assignment by the Snakes on Saturday.

It’s a bit surprising to see Kessinger released, as most DFA’d players are either traded or placed on outright waivers. An injured player can’t be placed on outright waivers, so a release is sometimes an indication that a player is hurt, though there’s been no reporting to suggest that’s the case with Kessinger. Another possibility is that he has been released to pursue an opportunity overseas, though that’s entirely speculative.

Kessinger, 27, has spent most of his career with the Astros. That club drafted him and gave him a chance to make his major league debut. But he was designated for assignment in December and flipped to the Diamondbacks in a small trade, sending minor league pitcher Matthew Linskey the other way. Kessinger never appeared in a game for Arizona, as he was optioned to Triple-A Reno prior to Opening Day.

His big league experience consists of just 70 plate appearances with the Astros, with a .131/.243/.213 line in those. His minor league work has naturally been greater in quality and quantity. Dating back to the start of 2023, he has slashed .268/.370/.400 on the farm for a 105 wRC+, thanks in large part to a strong 13.6% walk rate. He did that while playing all four infield spots, providing a good amount of defensive versatility. With Reno this year before being designated for assignment, he had a 27.7% walk rate, .235/.447/.324 batting line and 113 wRC+.

D-Backs Notes: McCarthy, Barrosa, Puk, Alexander

By | at

The Diamondbacks are optioning Jake McCarthy to Triple-A Reno, per the MLB.com transactions log. John Gambadoro of 98.7 FM in Phoenix suggests that Jorge Barrosa is likely to be recalled tomorrow to replace McCarthy in the outfield.

McCarthy has had a terrible start to the season. He has managed just three hits in his first 41 at-bats. The 27-year-old is coming off arguably the best year of his career. McCarthy hit .285/.349/.400 with eight homers and 25 stolen bases through a career-high 495 plate appearances last season. He earned the Opening Day assignment in center field as a result. His slump quickly cut into his playing time, as Alek Thomas has gotten the nod in center for five of the past six contests.

A good contact hitter, McCarthy has continued to put the ball in play. He has only fanned in six of 47 plate appearances, but he’s simply doing no damage. He only has one extra-base knock, a double, with five hard-hit balls (ones with an exit velocity of 95 MPH or better) on the season. McCarthy has never had imposing batted ball metrics, but the results became too much to ignore. He will be able to play every day in Reno rather than work in a fourth outfield role as he tries to get on track.

That’ll seemingly afford an MLB opportunity for the switch-hitting Barrosa. He made a brief major league debut last season, collecting three hits in eight games. He hit .270/.360/.421 over 75 Triple-A games last season. The Venezuela native is out to a stronger start in 2025, batting .295/.362/.495 with a trio of homers over 105 plate appearances in the Pacific Coast League.

Elsewhere on the roster, reliever A.J. Puk is scheduled for an MRI today (link via ESPN’s Jesse Rogers). The southpaw landed on the 15-day injured list on Saturday with inflammation in his throwing elbow. The Snakes will presumably provide a return timeline after getting the imaging results. Puk has been brilliant since the D-Backs acquired him from Miami at last summer’s deadline. He owns a 1.78 ERA with 55 strikeouts through 35 1/3 frames in an Arizona uniform.

On the other side of the injury ledger, Arizona activated Blaze Alexander from the 10-day IL and optioned him to Reno on Sunday. The 25-year-old infielder suffered an oblique strain early in his camp and only appeared in two Spring Training games. He played eight games on a rehab assignment. Rookie Tim Tawa and speedster Garrett Hampson are splitting the second base playing time with Ketel Marte on the injured list. Alexander would probably have gotten those reps had he been fully healthy throughout camp, but he’ll remain in Triple-A for the time being.

Diamondbacks Place A.J. Puk On 15-Day IL

By | at

The Diamondbacks announced several transactions in a shake-up of the club’s bullpen mix today.  The headline news is that closer A.J. Puk has been placed on the 15-day injured list (retroactive to April 18) due to inflammation in his left elbow.  Righty Bryce Jarvis and left-hander Joe Mantiply were optioned to Triple-A, and Arizona filled those three bullpen spots by calling up right-hander Drey Jameson, and selecting the contracts of right-handers Juan Morillo and J.P. Feyereisen.  To create roster space, the D’Backs also designated infielder Grae Kessinger for assignment.

Puk excelled after the Diamondbacks acquired him from the Marlins at last year’s trade deadline, and the southpaw has kept going this year by posting a 3.38 ERA in eight innings this season.  Even with the benefit of an absurd 97.6% strand rate, Puk has backed up his work with an excellent 34.3% strikeout rate and 5.7% walk rate.  In addition to all the swings and misses, Puk isn’t allowing much hard contact when his offerings do find a bat, and he has closed out all four of his save chances this season.

Unfortunately, his strong start has now been interrupted by a trip to the IL.  Puk’s lengthy injury history (which includes a Tommy John surgery) puts some extra focus on any elbow-related ailment, though there isn’t any indication at this point that his current issue is anything more than just inflammation.  Assuming no structural damage, Puk might be able to return after just a 15-day minimum, though it is just a matter of how long his elbow discomfort continues to linger.

Justin Martinez is now the likeliest candidate to step up as the new closer, with Shelby Miller and Jalen Beeks continuing in high-leverage setup roles.  Beeks is also the only southpaw in Arizona’s bullpen now that Mantiply has been sent to Reno.

Arizona’s 13-11 slugfest loss to the Cubs yesterday saw both Jarvis and Mantiply charged with three earned runs apiece, with each reliever throwing two-thirds of an inning.  The demotions to Triple-A can allow both pitchers to gather themselves after a difficult start to their seasons, while the D’Backs can get a few fresher arms into the bullpen.  This means Jameson is now in line to make his first MLB appearance since the 2023 season, Feyereisen will make his D’Backs debut after signing a minor league deal with the team in March, and Morillo is set to make his Major League debut after eight pro seasons.

Jameson last pitched in a big league game on July 6, 2023, as he underwent a Tommy John surgery that September that cost him the entirety of the 2024 campaign.  The 34th overall pick of the 2019 draft had posted a 2.63 ERA over 65 innings during the 2022-23 seasons, starting seven of 19 games but pitching mostly in a relief role as the 2023 season developed prior to his UCL injury.  The righty has worked exclusively out of the pen at Triple-A this season, and he has a 2.70 ERA over 6 2/3 innings in Reno while recording 11 strikeouts against zero walks.

Now that he’s back in good health, Jameson can resume his career and perhaps carve out a firm place for himself within Arizona’s bullpen.  He showed quite a bit of promise as a multi-inning reliever, as his past history as a starter gave him some extra durability coming out of the pen.  The D’Backs could look to deploy Jameson as a long man or a swingman, at least letting him get some innings under his belt before perhaps trying him for higher-leverage work.

The 26-year-old Morillo spent his entire career in the Dodgers organization before joining the D’Backs as a minor league free agent back in November.  Making his Triple-A debut this season, Morillo has thrown 6 1/3 innings of 1.42 ERA ball in Reno, with a 29.6% strikeout rate, 7.4% walk rate, and a huge 68.8% grounder rate to boot.  The latter number stands out even amidst Morillo’s history as a groundball pitcher, and the solid walk rate is also noteworthy given his control problems earlier in his minor league career.

Between his high velocity, strikeout potential, and ability to keep the ball on the ground, there’s plenty to like about Morillo if he can find the consistency that has eluded him for a good chunk of his minors career.  He’ll get a chance to show what he can do against MLB hitters during what might be a cup of coffee in the big leagues, depending on how Arizona chooses to align its bullpen beyond just this weekend.

Feyereisen has a 2.95 ERA over his 100 2/3 career innings in the majors, which covers parts of four seasons with the Brewers, Rays, and Dodgers from 2020-24.  Feyereisen had solid numbers in 2021 and looked to be breaking out as a high-leverage reliever in Tampa’s bullpen in 2022 before a shoulder injury resulted in surgery that cost him the entire 2023 season.

Resurfacing in L.A. last year, he had an 8.18 ERA in 11 innings at the big league level, as Feyereisen clearly still had some rust from his long layoff.  His 0.96 ERA in 9 1/3 innings in Reno this season is much more promising, and it was enough to give Feyereisen a shot with another NL West team as he looks to finally establish himself for steady bullpen work.

Kessinger played all over the infield in a backup capacity with the Astros during the 2023-24 seasons, appearing in 48 total games and hitting .131/.243/.213 in 70 plate appearances.  His career Triple-A slash line of .268/.370/.401 is much more impressive on paper, if undermined by the fact that those seemingly solid numbers are barely average in the hitter-friendly Pacific Coast League.

The Diamondbacks acquired Kessinger in a trade in January but he hadn’t yet seen any action on Arizona’s big league roster, and his tenure with the organization might already be over if he is claimed on waivers or traded.  Kessinger’s trade to Arizona in fact came after the Astros designated him for assignment previously, so history could repeat itself if another infield-needy team comes calling.  If Kessinger clears waivers and is outrighted off the 40-man roster, he must accept the assignment since he doesn’t have the MLB service time or a past outright that would allow him to opt into free agency.

Looking Ahead To Club Options: NL West

Over the coming days, MLBTR will look at next offseason’s option class. Steve Adams will highlight the players who can opt out of their current deals, while we’ll take a division-by-division look at those whose contracts contain either team or mutual options. Virtually all of the mutual options will be bought out by one side. Generally, if the team is willing to retain the player at the option price, the player will decline his end in search of a better free agent deal.

Arizona Diamondbacks

Arizona signed the veteran righty, who missed all of last season after undergoing shoulder surgery in January 2024. Graveman was hobbled by back discomfort this spring and began the year on the 15-day injured list. He has thrown a few bullpen sessions but has yet to begin a rehab assignment. During his most recent healthy season, Graveman worked to a 3.12 ERA across 66 1/3 innings between the White Sox and Astros.

Grichuk posted big numbers in a short-side platoon role for the Snakes in 2024. Arizona brought him back on a $5MM free agent deal. He’s making only a $2MM salary and will collect a $3MM buyout on his option at the end of the season. Grichuk hasn’t gotten much playing time, starting six of Arizona’s 19 games (all but one as the designated hitter). He’s out to a decent start, batting .240 with five doubles over 28 plate appearances.

Colorado Rockies

Farmer has been a rare bright spot in what has been a terrible Colorado lineup. The veteran utilityman has started 15 of their 18 games. He’s playing mostly second base and is hitting .345 with nine doubles, the second-most in MLB. Farmer isn’t going to keep hitting at this pace, but it’s an excellent start for a player who signed for $3.25MM after a down year (.214/.293/.353) with Minnesota.

Kinley signed a three-year extension during the 2022-23 offseason. The slider specialist had a brilliant first half to the ’22 campaign, but that was cut short in July by elbow surgery. Kinley hasn’t been the same pitcher since returning. He allowed more than six earned runs per nine in both 2022 and ’23. He has given up five runs (four earned) with seven strikeouts and six walks across 7 2/3 innings this season. Kinley owns a 6.03 ERA while walking more than 11% of opposing hitters over 88 frames since signing the extension.

The option comes with a $5MM base value. It would escalate by $500K apiece if Kinley finishes 20, 25, and 30 games — potentially up to $6.5MM. He has finished two contests in the early going. While the option isn’t especially costly, this is trending towards a buyout.

Stallings produced the best offensive numbers of his career for the Rox in 2024. He returned on a $2.5MM deal early in the offseason. Stallings has been more of the 1-b catcher behind Hunter Goodman. He has started seven games and caught 59 innings. It’s been a slow start, as he’s batting .125 with 12 strikeouts in 27 trips to the plate.

Note: Thairo Estrada’s one-year deal contains a ’26 mutual option, but he’s excluded from this exercise because he would remain eligible for arbitration if the option is declined.

Los Angeles Dodgers

  • Max Muncy, 3B ($10MM club option, no buyout)

This could end up being a borderline call. The Dodgers can keep Muncy around for what’d be his ninth season in L.A. on a $10MM price tag. That’s not an exorbitant sum for baseball’s highest-spending team. Muncy has generally been an excellent hitter in the middle of Dave Roberts’ lineup. He’s a career .230/.355/.482 hitter in Dodger blue. He remained as productive when he was healthy last season, posting a .232/.358/.494 slash over 73 games. An oblique strain cost him three months.

Muncy is out to a much slower start this year. He has yet to connect on a home run in 18 games. He’s batting .193 with 25 strikeouts in 68 plate appearances (a 36.8% rate). It’s very early, of course, but he’ll need to pick things up. Muncy turns 35 in August. NPB third baseman Munetaka Murakami will be posted for MLB teams next offseason. The Dodgers will very likely be involved on the 25-year-old slugger, so it’s possible they’d prefer to keep the position open early in the winter.

Taylor is in the final season of his four-year, $60MM free agent deal. He was coming off an All-Star season in 2021, when he hit .254/.344/.438 with 20 homers. His offense has trended down over the course of the contract, especially sharply over the past two years. Taylor fanned at a near-31% clip last season, batting .202/.298/.300 in 246 plate appearances. He has only been in the starting lineup three times this season.

The Dodgers have kept Taylor throughout his offensive struggles. They clearly place a lot of value on him as a clubhouse presence and appreciate the defensive versatility he provides off the bench. Still, it’s hard to imagine them paying the extra $8MM to exercise the option since he’s essentially the final position player on the roster. The option price would increase by $1MM if Taylor is traded or in the unlikely event that he reaches 525 plate appearances and/or makes the All-Star Game.

Note: Alex Vesia’s arbitration contract contains a ’26 club option, but he’s excluded from this exercise because he would remain eligible for arbitration if the option is declined.

San Diego Padres

Díaz finished last season in San Diego after being released by the Rockies. He re-signed on a $3.5MM deal as the Padres went with the affordable veteran catching tandem of Díaz and Martín Maldonado. He’s hitting .206 in 13 games, though he has taken seven walks against eight strikeouts.

  • Kyle Hart, LHP ($5MM club option, $500K buyout)

Hart, a soft-tossing lefty, returned to the majors after an excellent year in Korea. He signed a $1.5MM guarantee with a ’26 team option that has a $5MM base salary. The option price could climb as high as $7.5MM. It would jump $250K if Hart reaches 18 starts this year, $500K at 22 starts, $750K at 26 starts, and $1MM if he starts 30 games.

San Diego has given Hart a season-opening rotation spot. He has allowed seven runs over his first 11 2/3 innings. Hart has walked five with eight strikeouts and a below-average 8.3% swinging strike percentage.

King’s option is purely an accounting measure. He agreed to push $3.75MM of this year’s $7.75MM guarantee back to the end of the season in the form of a buyout — potentially buying the Padres a bit of flexibility for in-season trade acquisitions. Barring a major injury, he’s going to decline his end of the option and will be one of the top pitchers in next year’s class.

Wade agreed to a $1MM club option as part of a deal to avoid a hearing in his final year of arbitration. He was squeezed off the roster during Spring Training. Wade cleared waivers, accepted an assignment to Triple-A, then came back up last week. He’s playing center field with Jackson Merrill and Brandon Lockridge on the injured list. The option price is barely above the league minimum, but Wade is on the roster bubble and no guarantee to stick in the majors through the end of the season.

San Francisco Giants

San Francisco added Murphy on a two-year deal during the 2023-24 offseason. The veteran catcher has had a difficult time staying healthy throughout his career, and that’s continued in San Francisco. He played in only 13 games last year because of a knee sprain. He started this season on the shelf with a herniated disc that is going to keep him out for at least the first two months. This looks like a buyout.
