Diamondbacks Sign Anthony DeSclafani To Major League Contract

By | at

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.

Justin Martínez To Undergo Tommy John Surgery

By | at

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.

Diamondbacks Place Justin Martínez On IL With UCL Sprain

By | at

The Diamondbacks announced a series of roster moves today. Right-handers Kevin Ginkel and Bryce Jarvis have been recalled from Triple-A Reno and the club has also selected the contract of right-hander Tayler Scott. To open spots for those three, righty Jeff Brigham has been optioned to Reno while righties Justin Martínez and Christian Montes De Oca have both been placed on the 15-day injured list. Martínez has a sprained right ulnar collateral ligament while Montes De Oca has right elbow inflammation. To open a 40-man spot for Scott, righty Cristian Mena has been transferred to the 60-day IL.

The news on Martínez is ominous. The righty called the training staff to the mound during last night’s appearance. It was later relayed to reporters that he was experiencing elbow tightness. A sprain, by definition, involves some stretching or tearing of the ligament. Per Nick Piecoro of the Arizona Republic, manager Torey Lovullo says Martínez is now set for a second opinion on his injury.

Whenever a pitcher’s elbow is injured, it raises alarm bells about a possible surgery and those concerns certainly appear to be warranted here. It should be pointed out that not all sprains necessarily lead to a operation. To pick one recent example, Mason Miller was diagnosed with a mild UCL sprain in May of 2023 and ultimately did not head to the surgeon’s table. However, it took him four months to get back on the mound, as he wasn’t reinstated from the IL until September of that year.

It may take a few more days to determine the prognosis with Martínez but it seems like it will be an unfortunate development regardless. The righty seemed to break out as one of the best relievers in the sport last year. He tossed 72 2/3 innings for the Diamondbacks with a 2.48 earned run average. His 11.7% walk rate was certainly high but he struck out 29.5% of opponents and got grounders on 58.9% of balls in play.

The Diamondbacks believed in that breakout enough to lock up Martínez for the long term. He and the club agreed to a five-year extension in March that guarantees him $18MM, with two club options as well. Unfortunately, the first season of that deal has been a bit of a bust so far. Martínez already missed about three weeks due to some shoulder inflammation and is now back on the IL again with an even scarier diagnosis. He has only been able to throw 15 1/3 innings with a 4.11 ERA this year.

Martínez and A.J. Puk were supposed to be the two big weapons in the Arizona bullpen this year. Puk made just eight appearances before landing on the IL in mid-April due to elbow inflammation. He was later diagnosed with a flexor strain and transferred to the 60-day IL. His return timeline is unclear. Now it seems possible the Snakes may have to proceed without either of those hurlers for a while. They also put Kendall Graveman on the 15-day IL yesterday due to a hip impingement.

It’s the latest punch in what has been a bruising season for the Diamondbacks. They have lost starters Corbin Burnes and Jordan Montgomery to Tommy John surgery. Their bullpen has taken a number of hits. Some of their healthy pitchers have been underperforming. Though the Snakes came into the season with high hopes, they are now fourth in the National League West and 5.5 games back in the Wild Card race, a less than ideal time to be hemorrhaging key players.

If Martínez does have a serious injury, there would be one silver lining for the Diamondbacks in the long term. His extension has a conditional club option for 2032, valued at just $3MM. That would be triggered if he requires surgery or missed a certain number of days on the IL during the course of the deal.

While the club awaits for information there, they have to proceed with the business of the games on the schedule. They have added a number of arms to the active roster, which includes adding Scott to the 40-man. The 33-year-old Scott elected free agency last month after being designated for assignment by the Astros, which led to a minor league deal with the Diamondbacks.

He seemed to have a nice late-bloomer breakout with Houston last year, posting a 2.23 ERA over 68 2/3 innings. He struck out 25.2% of batters faced, though also gave out walks at a 12.4% pace. There was likely a bit of luck in that ERA, as his .230 batting average on balls in play and 84.9% strand rate were both to the fortunate side. ERA estimators like his 4.13 FIP and 4.04 SIERA pointed to some regression though still suggested he could be a capable big league arm.

The pendulum swing ended up being quite strong. He posted a 5.40 ERA through 16 2/3 innings to start this year. His .313 BABIP and 65.2% strand rate went to the other side of average as his strikeout rate fell to 20.5% and his walk rate climbed to 15.4%.

Since he’s out of options, that got him bumped off the roster and to free agency. Since landing with the D’Backs, he has thrown 3 1/3 scoreless innings for Reno. He may have a tenuous grasp on a roster spot, given his out-of-options status, but he, Ginkel and Jarvis will give the club three fresh arms after they used eight different pitchers to get through yesterday’s 11-inning game against the Mariners.

As for Mena, he just landed on the IL a few days ago with a shoulder strain. Lovullo said his absence would be measured in “weeks, not days.” Given today’s IL transfer, he will be ineligible for reinstatement until early August.

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.

Diamondbacks, Justin Martínez Agree To Extension

By | at

TODAY: The Diamondbacks officially announced the deal, which per the club’s announcement also includes a conditional club option for the 2032 season. According to Nick Piecoro of the Arizona Republic, the conditional option is worth $3MM and triggers if Martinez has elbow surgery at any point in the deal or spends a certain number of days on the injured list.

March 21: Right-hander Justin Martínez and the Diamondbacks have reportedly agreed to a contract extension, pending a physical. The deal will pay him $18MM over five years, with a couple of club options as well. He’ll get a $2MM signing bonus and a $1.5MM salary this year. He’ll then make salaries of $2MM, $3MM, $4MM and $5.5MM in the remaining guaranteed years. The 2030 club option is valued at $7MM followed by a $9MM option for 2031. It can max out at $39MM via escalators and those options. The guaranteed portion of the deal covers his remaining pre-arbitration and arbitration seasons, while the options give the Diamondbacks two potential extra years of control.

Martínez, 23, has a limited major league track record but has impressed in that time. He had a rough debut in 2023, allowing 14 earned runs in a small sample of ten innings. But he firmly established himself last year. He tossed 72 2/3 innings over 64 appearances for the D’Backs, allowing just 2.48 earned runs per nine innings. His 11.7% walk rate was definitely on the high side but he struck out 29.5% of batters faced and got grounders on 58.9% of balls in play.

He accomplished all that with an impressive arsenal, turning his Statcast page into a sea of red. His four-seam fastball and sinker both averaged over 100 miles per hour with Martínez also mixing in a splitter and a slider. He earned seven holds and eight saves last year, cementing himself as a key leverage arm for the Snakes.

Given that eye-popping performance, it’s understandable that the Snakes would look to lock him up. It’s also easy to see why Martínez might prefer to lock up some life-changing money now. He had just converted from the outfield to the mound in 2018 prior to being signed as an amateur out of the Dominican Republic. He got a $50K bonus, relatively modest compared to some of the multi-million-dollar bonuses high-profile prospects get. He has struggled with control problems throughout his minor league career and also had Tommy John surgery in 2021.

While Martínez is surely confident in his obvious talents, his trajectory has been more rocky than many other young players. That perhaps made him less likely to bet on himself than a player who already had millions in the bank and a smooth ride to the majors.

The deal is roughly in line with previous pacts for pre-arbitration relievers, as shown on MLBTR’s Contract Tracker. Emmanuel Clase got $20MM over five years from the Guardians going into the 2022 season. Clase then had between one and two years of service time, as Martínez does now. In both cases, the player locked up guaranteed money for their pre-arb and arb years, while giving up two free agent seasons via options. The Clase deal is tops for a reliever in this service bracket with Martínez coming in just below him.

Clase is an apt comparison for Martínez and a good illustration of what the Diamondbacks are hoping for. Clase was clearly a talented pitcher but had some uncertainty after missing the 2020 season due to a PED suspension. He pitched his first full season in 2021 and posted a 1.29 ERA over 71 appearances. The Guardians banked on Clase repeating that kind of performance going forward, a bet that has paid off. Clase has emerged as one of the best closers in baseball with a 1.72 ERA over the first three years of that deal.

The bar doesn’t need to be that high for Martínez. Even by the end of the deal, his salary stays fairly modest. Decent setup pitchers like Paul Sewald, Yimi García and Tommy Kahnle signed deals with salaries in the $7-8MM range this winter. That means Martínez will be a bargain even if he’s producing in the realm of those guys. But clearly, the ceiling is quite high and the Diamondbacks are hoping Martínez is a key part of the bullpen for years to come.

What remains to be seen is how Martínez will be utilized in the short term. Manager Torey Lovullo said this week, in video relayed by Alex Weiner of Arizona Sports, that he would likely not name a strict closer. He has two key lefties in A.J. Puk and Joe Mantiply, as well as righties Martínez and Kevin Ginkel. Based on Lovullo’s comments, he seems likely to put his pitchers in optimal platoon settings, at least until a more clear hierarchy emerges.

Moises Fabian of Mega 97.9 in New York first reported the details in Spanish, relaying the $18MM guarantee over five years and the club options valued at $7MM and $9MM. Nick Piecoro of the Arizona Republic later reported the same details in English. Ari Alexander of KPRC 2 reported the specific annual salaries.

The D-backs’ Closing Competition

By | at

The Diamondbacks entered the offseason in search of a new first baseman, a closer and some right-handed thump in the lineup, among other items on the to-do list. They’ve broadly succeeded, acquiring Josh Naylor from the Guardians to replace free agent Christian Walker and re-signing Randal Grichuk. The Snakes haven’t found a slam-dunk closer, but they signed a new (co) ace, shocking the industry with their signing of Corbin Burnes for six years and $210MM.

While there’s still one marquee free agent reliever on the market — David Robertson has yet to sign — it appears increasingly likely that the Diamondbacks will largely go with the arms who are already in camp as they look to sort out the ninth inning. Arizona’s payroll is already projected for a franchise-record $195MM. That’s a new highwater mark by a measure of nearly $30MM. We can always adopt the “never say never” mentality as long as there are a few viable closing options on the free agent and trade markets, but the D-backs may already have their closer in house. At present, A.J. Puk and Justin Martinez appear to be the front-runners.

Puk, acquired at the deadline from the Marlins in exchange for young slugger Deyvison De Los Santos and outfielder Andrew Pintar, enjoyed a quietly dominant season in 2024. His cumulative 3.15 ERA looks more good than great, but it’s skewed by a failed experiment wherein the Marlins tried to stretch him back out as a starter early in the season. Puk was clobbered for 17 runs in 13 2/3 innings. He moved back to the bullpen, and from that point forth was arguably the best reliever in the sport.

After giving up 17 earned runs in his four starts, Puk only allowed 11 more earned runs for the entire season. He posted a 1.72 ERA out of the bullpen in 2024, fanning a colossal 35% of his opponents against a terrific 5.1% walk rate. Opponents averaged only 86.6 mph off the bat against him in that time with a middling 32.6% hard-hit rate. Per Statcast, only five of his opponents’ batted balls in that time were barreled. Puk allowed a run in his second appearance with the D-backs and then went on a run for the ages, rattling off 23 2/3 scoreless innings with a 38-to-4 K/BB ratio. He punched out 44.7% of opponents in that career-best run.

Martinez was nearly as dominant for the early portion of the 2024 season. The young flamethrower posted a 1.60 ERA with a 27.5% strikeout rate and mammoth 64.5% grounder rate in his first 50 innings of work. His exit velocity and hard-hit rate were nearly identical to Puk’s marks as a reliever. An 11.5% walk rate was in clear need of improvement, but for a 22-year-old who averaged better than 100 mph on both his four-seamer and sinker, it’s hard to draw up a more promising start.

That run of dominance didn’t last the full season, however. While Martinez remained a solid reliever, his 3.90 ERA over the final 27 2/3 innings of his season was far less eye-catching. The young righty’s strikeout rate actually ticked up during that span, perhaps due to roughly doubling the usage of his four-seamer at the expense of his sinker, but his grounder rate fell sharply. There was surely some poor fortune in play, as Martinez was hampered by a .388 BABIP during this stretch despite continuing to limit hard contact (and allowing only one home run).

Whether in the ninth inning or working in a setup capacity, both Puk and Martinez will be in high-leverage roles this season. They were two of the D-backs’ top five arms in terms of their average leverage index — but not the top two. Paul Sewald’s departure in free agency subtracted one of Arizona’s top leverage arms, but it was actually righty Ryan Thompson who found himself most frequently in high-leverage spots, followed by Martinez and then by fellow righty Kevin Ginkel.

The 32-year-old Thompson isn’t the prototypical power arm often associated with pressure-packed, late-inning situations. He’s a sidearming righty who averages just 91 mph on his sinker and 92.5 mph on his lesser-used four-seamer. Thompson’s 19.1% strikeout rate was well below the 23.4% league average among relievers. However, he boasts a 61% grounder rate, rarely issues walks (5.5%) and posted nearly identical results versus righties (.254/.299/.377) and lefties (.254/.293/.377). He picked up two saves and 24 holds.

Ginkel, 30, has quietly emerged as a key arm in Phoenix. He was never a top prospect and didn’t truly establish himself as a reliable reliever until his age-28 season, in 2022. Over the past three seasons, he’s tossed 164 2/3 innings with a 2.95 ERA. It’s not necessarily flashy, as Ginkel is more good-than-great in terms of strikeout rate (26.5%), walk rate (7.3%), swinging-strike rate (12.5%), ground-ball rate (47.1%) and fastball velocity (96 mph average) in that time. Even with the lack of one standout area in which he truly excels, his above-average rates across the board have made him a consistent and reliable late-inning option for manager Torey Lovullo.

Also entering the mix is 34-year-old Kendall Graveman, who signed a one-year, $1.35MM deal after missing the 2024 season due to shoulder surgery. With 24 saves and 56 holds from 2020-23, Graveman is no stranger to late-inning work. After moving to the bullpen in Sept. 2020 with the Mariners, Graveman rattled off 197 1/3 innings with a 2.78 ERA, 24% strikeout rate, 10.3% walk rate and 49.2% grounder rate. At his best, Graveman averaged better than 96 mph on his heater and offered a Ginkel-esque blend of above-average strikeout, walk and ground-ball rates while sitting around 96 mph with his main offering. Whether he can return to that form in the wake of last year’s shoulder surgery is an open question.

However it shakes out, the Snakes look to have a solid quintet of arms rounding out the late-inning group at Chase Field. Lefty Joe Mantiply offers a solid middle-inning complement who has picked up around 12 holds per year over the past four seasons. A starter who doesn’t make the rotation (e.g. Jordan Montgomery, Ryne Nelson) could hold down another spot. Bryce Jarvis, Kyle Nelson and non-roster candidates like Shelby Miller, Scott McGough, John Curtiss and Josh Winder (among others) will vie for what’s likely one open spot.

There’s enough left on both the trade and free agent markets that it’s not impossible to envision a change still impacting Lovullo’s bullpen composition. Signing Robertson might be too pricey, likely pushing the D-backs into $200MM+ payroll territory for the first time, but if GM Mike Hazen ultimately finds a trade partner for Montgomery, any savings could make Robertson feel likelier. The Padres have been open to offers on Robert Suarez. Trading within the division probably isn’t either team’s first choice, though. A Ryan Helsley trade before next offseason feels virtually inevitable but also seems likelier to happen in-season at this point.

In any bullpen, there’s almost always room for one more addition. But, if this is the group the D-backs take into the season, they can still feel good about an impressive breadth of experienced late-inning arms who have the makings of a strong overall unit.

Diamondbacks Still Involved In Free Agent Relief Market

By | at

The Diamondbacks have pursued late-inning help all offseason. Arizona’s lone major league bullpen pickup was their waiver claim of Seth Martinez from Houston. The Snakes let Paul Sewald walk in free agency, leaving them without much in the way of experienced closers.

General manager Mike Hazen told reporters this afternoon that any late-offseason bullpen pickup is likelier to come by way of free agency than trade (relayed by Alex Weiner of Arizona Sports). The bullpen market has moved rapidly over the past four or five weeks. David Robertson stands as the top unsigned reliever. He has ample experience as both a closer and setup man. Robertson will be limited to a one-year deal at age 40, though he could command an eight-figure guarantee after posting an even 3.00 earned run average while striking out a third of opponents across 72 innings for the Rangers.

There are a handful of other free agent relievers who still seem likely to land big league deals. Kyle Finnegan, Andrew Chafin, and Phil Maton should all get major league contracts. Buck Farmer, Lucas Sims, Héctor Neris and injury returnees Kendall Graveman and Keynan Middleton are all unsigned. Craig Kimbrel has the most closing experience of any free agent, though he’s coming off a dismal season with the Orioles.

If the Diamondbacks don’t add anyone from that group, the ninth inning could be up for grabs in camp. Manager Torey Lovullo said yesterday that he’d prefer having an established closer but is “not going to force it” if a committee approach works better (link via Nick Piecoro of the Arizona Republic). Lovullo listed A.J. Puk, Justin Martinez and Kevin Ginkel as in-house candidates to close.

Puk was utterly dominant after the D-Backs acquired him from the Marlins at last summer’s deadline. The southpaw fired 27 1/3 innings of 1.32 ERA ball while striking out nearly 42% of batters faced. Puk has had three straight seasons as an excellent late-game weapon. He didn’t close much last year but recorded 15 saves two seasons ago.

Martinez turned in a 2.48 ERA over 72 2/3 innings in his first full big league campaign. The righty punched out nearly 30% of batters faced with a massive 58.9% grounder percentage. His sinker landed north of 100 MPH on average, while opposing hitters had no success against his splitter. Martinez doesn’t have Puk’s multi-year track record but clearly has closing stuff. Ginkel turned in a 3.21 ERA with a strong 26.5% strikeout rate across 70 innings. While he seems likelier to stick in a setup capacity, the righty has been a reliable bullpen piece for the past three years.

D-backs Select Logan Allen, Transfer Eduardo Rodriguez To 60-Day IL

By | at

The D-backs announced Wednesday that they’ve selected the contract of left-hander Logan Allen from Triple-A Reno and transferred lefty Eduardo Rodriguez from the 15-day IL to the 60-day IL to open a roster spot. The Snakes also recalled righty Justin Martinez from Triple-A. Right-hander Luis Frias and left-hander Tommy Henry were optioned to Reno to creative active roster space for Allen and Martinez.

It’ll be the first big league action since 2022 for the 26-year-old Allen (not to be confused by the other left-hander named Logan Allen, who solidified himself in the Guardians’ rotation with a strong rookie campaign in 2023).

The older Allen also pitched for Cleveland previously, to make matters more confusing. He’s a former eighth-round draft pick who’s appeared in parts of four big league seasons, working to a combined 5.89 ERA in 96 1/3 frames between Cleveland, San Diego and Baltimore. In a dozen innings with Reno, he’s pitched to a 3.00 ERA with nine strikeouts, three walks and a 50% ground-ball rate.

The “60-day” term on Rodriguez’s IL stint is retroactive to his original placement and does not reset to today. While Arizona had hoped he’d only miss a month originally, the veteran southpaw recently experienced renewed shoulder discomfort during a throwing session and had his rehab program paused. In light of that setback, it’s not especially surprising to see him pushed to the 60-day IL. His original placement was retroactive to March 25, meaning he’s now sidelined through at least Friday, May 24.

With Rodriguez now shelved for another five weeks at least, Arizona’s rotation will consist of Zac Gallen, Merrill Kelly, Jordan Montgomery and Brandon Pfaadt in the top four spots. Montgomery has also yet to make his season debut but it scheduled to do so on Friday. Twenty-six-year-old righty Ryne Nelson currently holds the fifth spot, but he’s yielded eight runs in 13 2/3 innings this season and carries a 5.31 ERA in 157 2/3 frames dating back to last year. His grip on that rotation spot is not exactly iron-clad.

Diamondbacks Designate Zach Davies For Assignment

By | at

The Diamondbacks have designated right-hander Zach Davies for assignment, the team announced. Fellow righty Justin Martinez has been recalled from Triple-A to take his place on the active roster.

Davies was a solid back-of-the-rotation starter for Arizona last year, making 27 starts with a 4.09 ERA. That hasn’t been the case this season, as he is pitching to a 7.00 ERA in 18 starts, interspersed between two separate stints on the injured list. Despite his poor performance, the D-backs have kept him around, since they have struggled to find reliable starters to pitch behind Zac Gallen and Merrill Kelly all year. Now, however, with just five games remaining in the regular season and the playoffs right around the corner, Arizona no longer has much need for an innings eater on the roster.

This could be an indication the Diamondbacks are planning to make an addition to the 40-man roster ahead of the playoffs, or it could simply be a way of making room to add an extra relief arm for the final five games of the regular season.

Davies, who is making $4.7MM this season and has a $300K buyout for next year, is likely to go unclaimed on waivers, at which point the D-backs would be responsible for the guaranteed salary remaining on his contract. Still just 30 years old, he shouldn’t have trouble finding a new club in the offseason, although he might have to settle for a minor league deal.

Martinez, a right-handed reliever, is the team’s No. 24 prospect, per MLB Pipeline. He made his MLB debut earlier this season and has pitched to a ghastly 14.63 ERA in a few brief call-ups to the big league squad. His numbers at Triple-A are much more palatable; he has a 4.20 ERA in 47 games, although his 21.2% walk rate is still alarming. It’s unlikely he’ll play much of a role while the D-backs are fighting for a postseason berth, but he’ll provide manager Torey Lovullo with an extra arm out of the ’pen.

Diamondbacks Place Merrill Kelly On IL, Option Joe Mantiply

By | at

The Diamondbacks announced a series of roster moves today, with right-hander Merrill Kelly being placed on the 15-day injured list due to right calf inflammation, retroactive to June 25. They also optioned left-hander Joe Mantiply to Triple-A Reno. In corresponding moves, righties Kevin Ginkel and Justin Martinez were recalled from Reno.

At this point, it’s unclear how serious Kelly’s injury is, but it’s a notable loss for the club nonetheless. The Diamondbacks have a fairly top-heavy rotation with Kelly and Zac Gallen being the two most effective members. Gallen has an excellent 2.84 ERA on the year and Kelly isn’t far behind with a 3.22 mark. Then there’s a notable drop to the 4.31 ERA of Tommy Henry, the 4.97 of Ryne Nelson and the 7.82 of Zach Davies.

The Diamondbacks are leading the National League West but have a couple of clubs on their heels as each of the Dodgers and Giants are within three games. With the All-Star break now effectively two weeks away, they will have to forge ahead without Kelly for at least that long. Drey Jameson has been with the big league club in a long relief role and could perhaps step into the rotation. Brandon Pfaadt got some big league starts earlier this year but posted an 8.37 ERA in those before getting optioned back down. Konnor Pilkington is also on the 40-man but has been struggling in the minors this year.

As for Mantiply, he posted a 2.85 ERA last year and even got selected to the All-Star game but has taken a step back this year. He’s gone on the injured list a couple of times already, once due to left shoulder inflammation and another time for a right hamstring strain. Around those ailments, he’s tossed 15 2/3 innings with a 5.74 ERA. His peripherals are still pretty similar to last year’s as a 50.8% strand rate seems to be pushing his ERA up. Nonetheless, he now finds himself headed to Reno to get into a groove.

Martinez, 21, will be making his major league debut as soon as he gets into a game. He served largely as a starting pitcher in the lower levels of the minors but required Tommy John surgery in 2021. After a long injury layoff and the minor leagues getting cancelled by the pandemic in 2020, he came back as a reliever last year. He tossed 38 innings across four different levels, finishing the year at Triple-A. He posted a 3.32 ERA in that time with an incredible 36.7% strikeout rate but 13% walk rate.

Despite the free passes, the club was intrigued enough to add him to the roster in November to prevent him from being selected in the Rule 5 draft. This year, he’s been in Triple-A, tossing 28 innings thus far. He has a 4.18 ERA, striking out 29.7% of opponents but with an astonishing 21.1% walk rate. Despite the control issues, he was recently ranked the club’s #21 prospect at Baseball America and #12 at FanGraphs.
