Merrill Kelly

Tigers Interested In Merrill Kelly, But Prioritizing Relief Pitching

By Mark Polishuk | July 29, 2025 at 2:17pm CDT

A once-dominant season for the Tigers has sprung some leaks, as the club has lost 13 of its last 16 games.  Detroit still has a nine-game lead in the AL Central so it’s far from panic mode just yet, but some help is clearly needed at the deadline, as evidenced by yesterday’s trade that brought Chris Paddack to the rotation in place of the injured Reese Olson.

Another rotation upgrade could be under consideration, as John Gambadoro of 98.7 FM Phoenix writes that “the Tigers like Merrill Kelly.”  The Diamondbacks right-hander is seen as likely to be moved by the deadline since Arizona has started moving other impending free agents like Josh Naylor, though it remains to be seen if the Tigers could emerge as an ardent suitor.  Gambadoro notes that the Tigers are primarily focused on adding relief pitching, which tracks with recent reports linking Detroit to such bullpen arms as Jhoan Duran, Griffin Jax, and David Bednar.

This isn’t to say that president of baseball operations Scott Harris isn’t exploring plenty of options, as the Tigers are also reportedly showing interest in third basemen like Ke’Bryan Hayes and another big Arizona trade chip (and former Tiger) Eugenio Suarez.  Detroit’s rotation also needed help even before Olson went down, as there’s still uncertainty over the fifth starter’s role behind Tarik Skubal, Jack Flaherty, Casey Mize, and now Paddack.

Adding Kelly would be a nice way to solidify the starting pitching situation, which in turn would indirectly also make things a little easier on Detroit’s struggling relief corps.  Kelly has bounced back well from an injury-shortened 2024 season by posting a 3.22 ERA over 128 2/3 innings for the D’Backs this year.  His 23.5% strikeout rate, 45% groundball rate, and 7.4% walk rate are all above league average, though a .247 BABIP has helped Kelly get away with allowing a lot of hard contact.

His higher 3.78 SIERA reflects that batted-ball luck, though Kelly has continued the good form he has shown for almost all of his seven-season run with the Diamondbacks.  Kelly also posted good numbers during Arizona’s NL pennant run in 2023, and this postseason experience would be helpful to a Tigers squad that surely has designs on making a deeper playoff run this October.  Only around $2.31MM remains on Kelly’s $7MM salary, making him an affordable fit for pretty much any contender.

Kelly discussed his situation with the Arizona Republic’s Nick Piecoro and other reporters on Saturday, following what could be the right-hander’s final start in a D’Backs uniform in 2025, but perhaps not ever.  Even if he is dealt before Thursday’s deadline, Kelly said he and his agent have both expressed interest in a reunion in free agency this winter.

“Obviously, I understand the nature of the beast and the business aspect of it,” Kelly said.  “The idea of, if I do get traded and if I do go somewhere…the chance to win is obviously in the forefront of my mind.  That all being said, I love being here. I have always loved being here. I would always be open to being a Snake moving forward.”

Diamondbacks Open To Moving Both Zac Gallen, Merrill Kelly

By Nick Deeds | July 28, 2025 at 12:30pm CDT

The Diamondbacks remain a sub-.500 baseball team with just days to go until the trade deadline. They’re ten games back of the Dodgers in the NL West and six games out of a playoff spot, leaving them with minimal hope of a miracle run back into postseason contention. As a result, they’ve turned their attention more fully towards selling with deals that shipped Josh Naylor to Seattle and Randal Grichuk to Kansas City in the past week. That sell-off only figures to get more substantial from here, and Ken Rosenthal of The Athletic suggested over the weekend that after initially resisting the idea of trading both Zac Gallen and Merrill Kelly in the coming days the pair could both be pitching for other teams in August if the club receives strong enough return packages for them.

As the team’s downward trajectory in the standings has continued, the value in keeping one of Gallen or Kelly around in the second half has diminished considerably due to the lack of a realistic path to the postseason. Still, either one would receive and reject a Qualifying Offer this winter if retained, allowing the Diamondbacks to recoup value in the form of draft pick compensation. Additionally, Rosenthal suggests that Arizona brass is concerned about the club’s pitching depth if it were to lose both Gallen and Kelly from the fold. Given that, the Diamondbacks would need to not only receive more than the value of the draft pick they could recoup over the winter to move their two starters, but also enough to make up for the additional strain on their rotation.

That the Diamondbacks would at least consider trading both Gallen and Kelly makes sense. After all, Fangraphs projects them for a meager 5.4% chance at the postseason entering today, and with a core of talent still in place to help bring the club back into contention for 2026 and beyond augmenting those years ought to be the club’s priority. It’s understandable, however, that Arizona is looking at its group of injured pitchers (including Corbin Burnes, A.J. Puk, and Justin Martinez) and the strain losing reliable arms like Gallen and Kelly would put on their remaining healthy arms with some trepidation. That’s why the club is already reportedly targeting young pitching this summer, and it stands to reason that if the Diamondbacks can land a big-league ready starting pitcher or two who can be reliably plugged into their rotation to eat innings down the stretch, that would go a long way to convincing them to part with their veteran rentals.

As noted by Nick Piecoro of the Arizona Republic, GM Mike Hazen acknowledged over the weekend that he was receiving “strong interest” in both of his rental starters. That’s hardly a shock, as both Kelly and Gallen have an argument as the best rental pitcher available. Kelly has pitched to a 3.22 ERA with solid peripherals this year that’s consistent with his status as a solid #2 starter, while Gallen is in the midst of a down season but has shown ace upside in the past with third-, fifth-, and ninth-place finishes in NL Cy Young voting over the years. Both pitchers offer solid enough track records of success in the postseason as well, something that other intriguing rentals like Dylan Cease and his 12.91 career ERA in the postseason cannot boast, though Kelly’s excellent 2.25 career ERA in the playoffs shines much brighter than the 4.54 figure of Gallen.

Interest in starting pitching in general is strong league wide this year, so it’s hardly a shock that Gallen and Kelly are no exception to that. The Blue Jays and Cubs are among the teams to have been directly connected to at least one of Kelly or Gallen at this point, but a number of other teams are known to be on the prowl for a starter. That includes the Yankees and Giants, both of whom appear to be prioritizing rotation help, although other clubs like the Padres, Tigers, Mets, Red Sox, and Astros all also expected to be at least somewhat involved in the rotation market. With so many teams looking for starters, it seems likely that the Diamondbacks will have plenty of intriguing offers for their pair of veteran hurlers that they can sort through in the coming days.

Diamondbacks Reportedly Planning To Be Deadline Sellers

By Darragh McDonald | July 24, 2025 at 4:11pm CDT

The Diamondbacks seem to have picked a lane. Ken Rosenthal of The Athletic reports that they are informing rival clubs that they plan to trade at least some of their veteran players, though the extent of their sell-off is still to be determined. Many of their players are impending free agents and qualifying offer candidates, so the trade returns would have to notably eclipse QO compensation for the Diamondbacks to pull the trigger on trading one of those players. It also seems they don’t want to totally wave the white flag on 2025, so they won’t just sell any theoretical candidate.

It’s a tricky spot for the club to be in. As noted by Rosenthal, the club may not want to punt the 2025 season. Back in 2023, they snuck into the playoffs with 84 wins and ended up going all the way to the World Series, eventually falling to the Rangers. But their 2025 club has been decimated by injuries, particularly on the pitching side. Corbin Burnes, Jordan Montgomery, A.J. Puk, Justin Martínez and others have required season-ending surgeries. Notable position players like Gabriel Moreno and Pavin Smith are also on the shelf.

Despite all of that, the club has hung around the playoff race. General manager Mike Hazen has spoken about how he would like to act as a buyer at the deadline but needed the club to justify that position by winning games. They came out of the All-Star break with a sweep of the Cardinals, but then got swept by the Astros. They are currently 50-53 and 5.5 games out of a playoff spot. They’re not totally buried but it seems the club has decided this may not be their year and some decisions should be made to help the club focus on the future.

Moving more clearly into seller position will have its advantages. With the expanded postseason, many clubs are still in contention, which makes it a seller’s market. By making some attractive players available, the front office could do a lot to help the Diamondbacks in the future.

Young pitching seems likely to be a focus. The rotation is set to lose Zac Gallen and Merrill Kelly to free agency. Burnes will still be recovering from his surgery for a lot of next year. The 2026 rotation projects to include Eduardo Rodríguez, Brandon Pfaadt and Ryne Nelson. Rodríguez and Pfaadt are struggling this year. Nelson is doing well but has only really had a rotation spot for about six weeks, having been in long relief until injuries opened a spot for him. The Snakes could improve their 2026 rotation outlook by getting some younger pitchers now.

Eugenio Suárez seems the most likely player to be traded. He’s an impending free agent and his stock is tremendously high right now, since he’s been on a heater for more than a year. Dating back to July 7th of last year, he has 60 home runs, a .277/.334/.607 batting line and 154 wRC+. He has a $15MM salary this year, which will leave about $5MM left to be paid out at the deadline.

He will be highly attractive. He’s already been connected to teams like the Cubs, Yankees, Mariners and Reds. Rosenthal mentions those teams and adds the Mets to the pile. John Gambadoro of Arizona Sports 98.7 FM Phoenix says 12 teams in total have contacted the Snakes about Suárez. Bob Nightengale of USA Today says the Mariners and Yankees are the most aggressive of the suitors, though the market appears to be very crowded.

The Mets have a cluster of young infielders which includes Brett Baty, Mark Vientos, Luisangel Acuña and Ronny Mauricio. Baty is the only one in that group having a good season, though he’s also been playing some second base, so it’s possible he could co-exist with Suárez. The Mets are also reportedly willing to trade from that infield depth, so it’s possible Suárez could be brought in as part of a bigger shake-up.

With that hot market, it’s easy to the appeal for the Snakes in cashing in. It’s also possible that it could hurt their 2025 chances less than trading some of their other veterans. Jordan Lawlar is one of the top prospects in baseball but has been blocked from getting a big league audition. He can’t be expected to come up and produce at the same level as Suárez but it’s possible he could run with the opportunity and make up some of what is lost. He is currently out with a hamstring strain but could be back in the coming weeks. Even if he doesn’t come up and immediately succeed, there would be value in the Diamondbacks giving him an extended audition before they have to make key offseason decisions about their lineup.

There are some parallels on the other side of the infield. Josh Naylor is an impending free agent and consistently above-average hitter. Dating back to the start of 2022, he has a .272/.336/.462 line and 121 wRC+. He is making $10.9MM this year, which will leave a little under $4MM to be paid out as the deadline nears. Smith has been putting up big numbers the past two years and could take over for Naylor at first, though he’s currently sidelined by an oblique strain. Naylor has been connected to the Mariners though they are reportedly more interested in Suárez.

As mentioned, Gallen and Kelly are also impending free agents. Rosenthal has previously suggested the club is unlikely to trade both as they will still need innings to get through the season. That’s a bit of an odd hedge. They could always grab cast-offs from other clubs, Erick Fedde types, to finish the year. But perhaps the Snakes are trying to walk a fine line where they sell some pieces without totally punting their 2025 campaign. Trading one of this duo but keeping the other could be a compromise along those lines.

Kelly is having the better season but Gallen has higher theoretical upside. Jesse Rogers of ESPN recently reported that teams were a bit more interested in Gallen, despite the recent results. Gallen, 29, has a 5.58 ERA and 22.2% strikeout rate this year. Some of that might be luck, as he his 65.1% strand rate and 16.7% home run to fly ball rate are both to the unfortunate side. His 4.16 SIERA suggests he might not be too far from his past self, though his hard hit rate and barrel rate are also quite high this year, so it might not be all luck.

From 2022 to 2024, Gallen tossed 542 innings with a 3.20 ERA, 26% strikeout rate, 6% walk rate, 44.4% ground ball rate, 3.20 FIP and 3.60 SIERA. FanGraphs credited him with 12.1 wins above replacement in that time, seventh among all pitchers. It’s understandable that teams looking for rotation upgrades, particularly for the postseason, would be intrigued by acquiring Gallen and getting him back to that level. He is making $13.50MM this year, which will leave about $4.5MM left to be paid out at the deadline. He’s been connected to the Blue Jays but should be of interest to several other pitching-needy teams.

Kelly, 36, doesn’t have the same ace ceiling but has been more steady. He is in his seventh season with the Snakes and has a 3.76 ERA. That figure was 3.37 in 2022 and 3.29 in 2023. Last year, injuries limited him to 13 starts and his ERA jumped a bit to 4.03. This year, it’s back down to 3.32. He has a 24.2% strikeout rate, 7.6% walk rate and 44.2% ground ball rate. He’s making $7MM this year, so he’ll have just $2.33MM left to be paid out at the deadline.

Any of those four players is a plausible candidate to receive and perhaps a reject a qualifying offer candidate at season’s end. The exact value of the QO hasn’t been set, but is likely to be somewhere around $22MM. The 2024-25 qualifying offer was $21.05MM and it usually goes up annually.

The Diamondbacks are a revenue-sharing recipient, which affects their compensation for a player rejecting a QO and signing elsewhere. If the player ultimately signs for $50MM or more, the Snakes would get an extra draft pick just after the first round. Less than $50MM and the pick would come just ahead of the third round.

While teams value draft picks, drafted players usually take a few years to reach the majors. The Diamondbacks are presumably hoping to contend again in the near future, while they still have core players like Corbin Carroll and Ketel Marte putting up great numbers. By trading these impending free agents, they could garner returns of prospects who are closer to the majors than anyone they would draft next summer. That should move the needle to the trade side, though it also seems like they’re leery of totally bottoming out their chances of hanging in the race this year.

In addition to those names, the Diamondbacks could also sell other impending free agents, such as Randal Grichuk and Shelby Miller. Those players wouldn’t bring back huge returns, though they’re also less essential to the club contending down the stretch in 2025. The Snakes have also reportedly gotten some interest in Lourdes Gurriel Jr., who is signed through 2027. They have also reportedly listened to offers on controllable outfielders like Alek Thomas and Jake McCarthy. Time will tell how aggressively they smash the sell button but it seems like the Diamondbacks will be one of the most interesting clubs to watch over the next week.

D-backs Expected To Target Young Pitching At Deadline

By Steve Adams | July 16, 2025 at 8:08pm CDT

The Diamondbacks enter the unofficial second half of the season with a 47-50 record  that has them buried by 11 games in the NL West and sitting 5.5 games out of the final NL Wild Card spot (with four teams to leapfrog to get there). General manager Mike Hazen said two weeks ago that he hopes the team puts him in a position to buy at the trade deadline. The team has gone 4-8 since he made those comments. FanGraphs gives the Diamondbacks just a 10.2% chance to make the postseason. Baseball Prospectus is ever so slightly more charitable at 11.3%. The D-backs open the second half with a three-game series against a 51-46 Cardinals team. They follow that with three against a last-place Pirates squad but then face a pair of first-place clubs — Tigers, Astros — in the final stretch leading to the trade deadline.

Suffice it to say, the outlook for 2025 isn’t great. Hazen spoke with Nick Piecoro of the Arizona Republic at this week’s All-Star festivities and acknowledged that the Snakes “are running out of time” and that they would “need to play pretty exceptional” baseball to get back into a buy position prior to the deadline. Hazen also conceded that he’s been fielding inquiries from clear buyers already but naturally wouldn’t commit one way or another when asked about his willingness to make a move well ahead of the July 31 deadline.

[Related: Arizona Diamondbacks Trade Deadline Outlook]

Arizona isn’t short on marketable assets, even if the goal is to hang onto players controlled beyond the current season. Corner infielders Eugenio Suárez and Josh Naylor would be two of the best bats on the market. Suárez was plunked on the hand in last night’s All-Star Game but remained in the contest. Postgame x-rays were negative. Randal Grichuk would be a nice role player for a team looking for a right-handed bat with a long track record versus lefties.

On the pitching side of things, Zac Gallen has struggled all season but has an excellent track record. He looked to be turning a corner with terrific starts on July 1 and 7 (combined 13 innings with one run on 10 hits and a 19-to-1 K/BB ratio) before being rocked for six runs in his final start prior to the break. Merrill Kelly (3.34 ERA in 116 frames) has been strong all season, though, as have relievers Jalen Beeks and Shelby Miller. Both Beeks and Miller are on the injured list — the latter due to a forearm strain on which he is ominously seeking a second opinion. If one or both returns in timely fashion, they’d be obvious trade targets for clubs seeking affordable bullpen help.

It’s at least possible the Diamondbacks will listen on more controllable players. They’re reportedly listened on their outfield depth. Corbin Carroll isn’t going anywhere, but each of Alek Thomas, Jake McCarthy, Lourdes Gurriel Jr. and Grichuk could hold varying levels of appeal.

If the D-backs do end up as a seller, which seems likely, Piecoro suggests they’ll prioritize adding pitching they can control beyond the current season. That’s only logical with Corbin Burnes facing a lengthy recovery from Tommy John surgery and both Kelly and Gallen hitting free agency at season’s end. Lefties Blake Walston and Tommy Henry also had UCL surgeries this season — Walston in March, Henry in June. Young righty Cristian Mena is on the 60-day IL due to a shoulder strain. The injury problems extend to the bullpen, where top relievers Justin Martinez and A.J. Puk had Tommy John surgery just last month.

Looking ahead to the Diamondbacks’ 2026 rotation mix, they’ll have Brandon Pfaadt, Eduardo Rodriguez and Ryne Nelson all locked into spots. The former two have struggled to ERAs north of 5.00 this season. Nelson has a 3.68 ERA in 78 1/3 innings. Other in-house options, like 24-year-old righty Yilber Diaz (one of their top prospects entering the season) and 27-year-old Bryce Jarvis, have had nightmare seasons in Triple-A. Diaz currently has an ERA north of 11.00.

Given the broad-reaching slate of injuries and departing free agents, it’s sensible to focus on pitching help to the extent possible. That doesn’t mean the D-backs will turn away offers that include enticing young hitters to take on lesser pitchers, but if two packages of comparable quality are offered up, the D-backs seem likely to favor one that skews toward the pitching side of things.

Of course, the D-backs needn’t focus entirely on rebuilding their staff in the next two weeks. They have nearly $75MM in salary set to come off the books via free agency and could save further money via trades in the next two weeks. Their arbitration class isn’t large, and one of their most notable arbitration salaries (Puk) could come off the books via non-tender. His UCL surgery was just last month, and 2026 is Puk’s final season of club control. There should be ample space — and need — to pursue help both in the rotation and the bullpen this offseason.

Diamondbacks Notes: Beeks, Graveman, Gallen, Kelly, Miller

By Mark Polishuk | July 12, 2025 at 8:51am CDT

Prior to yesterday’s 6-5 loss to the Angels, the Diamondbacks placed left-hander Jalen Beeks on the 15-day injured list due to lower back inflammation, with a retroactive placement date of July 8.  Right-hander Kendall Graveman was activated from the 15-day IL in the corresponding move.

It doesn’t appear as Beeks’ injury is overly serious, as manager Torey Lovullo told reporters (including the Arizona Republic’s Nick Piecoro) that the hope is that Beeks will miss just the minimum 15 days, with the retroactive time and the All-Star break factoring into that number.  This means Beeks should be able to return in plenty of time before the July 31st trade deadline, which is perhaps noteworthy if the 46-49 Diamondbacks end up being sellers.

Beeks is just a couple of days removed from his 32nd birthday, and he has a 4.39 ERA, 51.8% grounder rate, 22.9% strikeout rate, and 8.9% walk rate over 41 relief innings this season.  While the K% and BB% numbers aren’t anything special, Statcast has liked Beeks’ work on the whole, and his ability to induce soft contact and keep the ball on the ground have helped the southpaw deliver some respectable numbers.  Beeks’ numbers are somewhat inflated by two nightmarish outings against in the Marlins in late June, which accounted for eight of the 20 earned runs he has allowed all year.

Should Arizona indeed decide to sell, Beeks is a natural trade chip as an impending free agent, and plenty of clubs should have interest in an inexpensive veteran lefty.  The D’Backs signed Beeks to a one-year, $1.25MM deal just before Opening Day, after Beeks was released at the end of spring camp from a previous minor league deal with the Astros.

An IL stint this relatively close to the deadline could throw a wrench into Beeks’ trade candidacy, as he has now joined the long list of Diamondbacks pitchers sidelined by injuries.  Graveman has been on the IL twice this season, first due to a lumbar strain and then this latest placement due to a hip impingement that cost him a little over a month of action.  These two IL stints have limited Graveman to just 10 appearances and 9 1/3 innings this season.  Graveman’s ERA is 8.68, though one six-run implosion against the Reds on June 7 is largely responsible for Graveman’s ungainly bottom-line statistics.

The D’Backs have faced such a swath of pitching injuries that it may impact their deadline plans as either buyers or sellers.  Zac Gallen and Merrill Kelly are both impending free agents and oft-cited trade candidates, yet according to the Athletic’s Ken Rosenthal, the Diamondbacks “are unlikely” to move both starters at the deadline for the simple reason that the club still needs to fill innings for the remainder of the year.  The Snakes have already seen their starter depth depleted by Tommy John surgeries to Corbin Burnes, Jordan Montgomery, and Blake Walston, while Tommy Henry underwent an internal brace procedure in late June.  A shoulder strain has also sidelined Cristian Mena until at least the second week of August, as per his timeline on the 60-day IL.

Gallen is in the last few months of his final arbitration-eligible season, while Kelly is in the last year of what has now become a three-year, $24MM contract when Arizona made the easy call to exercise its $7MM club option on the right-hander last November.  Kelly has been the significantly better of the two pitchers this season with 2.0 fWAR to Gallen’s 0.1 fWAR, though Gallen is perceived to have the higher upside as a former front-of-the-rotation type.  The Diamondbacks figure to receive plenty of offers for both pitchers prior to July 31, so the decision of who stays and who goes will just come down to which offer the Snakes prefer.

In another injury update, Lovullo said Shelby Miller will be visiting Dr. Keith Meister to get a second opinion about the forearm strain that sent Miller to the 15-day IL earlier this week.  Lovullo said that surgery may well be an option for the reliever, but Miller is also still considering treatments that would allow him to return to action at some point in 2025.

At the very least, it certainly doesn’t seem like Miller will be able to return before the deadline, which reduces or (more realistically) wipes out his trade value.  This injury has cast a pall over what had been an outstanding season for Miller, a minor league signing who has delivered a 1.98 ERA over 36 1/3 bullpen innings for Arizona.

D-Backs GM Mike Hazen Talks Trade Deadline

By Anthony Franco | June 25, 2025 at 10:48pm CDT

The Diamondbacks dropped this afternoon’s series finale against the White Sox, falling to 41-39. They’re 3.5 games back with four teams in front of them in a crowded NL Wild Card picture. As Darragh McDonald and I discussed on this week’s MLBTR podcast, Arizona is one of the most interesting bubble teams five weeks from the deadline. They’re still in the race but have been battered by injuries, leaving them shorthanded as they enter a pivotal stretch of the season.

General manager Mike Hazen spoke with ESPN’s Jesse Rogers on Tuesday and said he has started to receive calls from opposing clubs gauging their interest in selling. Hazen jokingly likened the rival executives to sharks circling but noted that the D-Backs aren’t interested in dealing away talent at this point.

“We have good players, so I don’t see why we shouldn’t be able to play good baseball and stay in this and then get those guys back and maybe be able to add on at the deadline,” the GM said, referencing the recent injured list placements to right fielder Corbin Carroll and catcher Gabriel Moreno. Arizona has also recently lost Corbin Burnes, Justin Martinez and A.J. Puk, but none of them will be back this season. Hazen acknowledged there may eventually be “a critical mass of injuries” that forces them to reconsider but added he “still (thinks they) have every opportunity to be competitive.”

It’s what should be expected from a bubble team’s GM this far out. It’d be far more surprising if the D-Backs were already open for business. They’ll know more in a month about their place in the standings and on the statuses of Carroll (wrist fracture) and Moreno (broken index finger). Hazen conceded, however, that playoff spots will be tough to come by in a National League that has ten teams that are above .500 at the moment.

If they’re still within a few games of a playoff spot in July, they’ll be motivated to buy. The D-Backs narrowly missed the postseason a year ago. Ownership subsequently approved a franchise-record payroll to support an excellent lineup. Their pitching plans have largely been decimated by injuries and/or underperformance from their free agent acquisitions. That has kept them around .500 despite an offense that trails only the Dodgers and Cubs in runs — one year after they led MLB in scoring.

The ideal outcome is that the team plays well enough that the front office can add to the pitching staff, especially in the bullpen. If things go in the opposite direction over the next month, they’d have no shortage of veteran players to shop. Josh Naylor, Zac Gallen, Merrill Kelly, Eugenio Suárez, Shelby Miller and Jalen Beeks are all impending free agents. Gallen seems unlikely to re-sign, and it’s tough to see the Diamondbacks retaining both Naylor and Suárez while again blocking Jordan Lawlar’s path to infield at-bats. The D-Backs could consider a qualifying offer for any of the first four players, though it’s unlikely they’d QO all four since there’d be an argument for each of them to accept.

Naylor and Suárez have been middle-of-the-order run producers and would be among the top rental bats if the D-Backs made them available. USA Today’s Bob Nightengale wrote this morning that the Yankees have shown some early interest in Suárez with a likely infield need. Acquiring a third baseman would free them to move Jazz Chisholm Jr. back to second base and move DJ LeMahieu to a utility role. Suárez is currently day-to-day after being hit by a pitch on Monday. He sat out the final two games of the Chicago series.

Gallen has had a poor season but has the pedigree to attract attention. The 36-year-old Kelly is churning out another low-3.00s ERA season while striking out a quarter of opponents. Miller, who is playing for barely more than the league minimum after signing an offseason minor league contract, would be a top bullpen target. He’s carrying a sub-2.00 ERA with a 27% strikeout rate while pitching his way into the ninth inning. Beeks has pitched well in a setup capacity and would be a target for teams seeking left-handed relief.

The Diamondbacks’ Surprisingly Middling Rotation

By Anthony Franco | May 21, 2025 at 11:25pm CDT

Few teams have more aggressively added veteran rotation help over the past two years than the Diamondbacks. As shown on MLBTR's Contract Tracker, 15 free agent starting pitchers have signed for at least a $20MM average annual value since the start of the 2023-24 offseason. The D-Backs have been responsible for three of them.

If we exclude Shohei Ohtani, who was obviously signed more for his bat,  Arizona is the only team to sign three such contracts over the past two winters. The Dodgers (Yoshinobu Yamamoto and Blake Snell) are the only other club that has signed more than one.

Arizona began with a four-year, $80MM contract for Eduardo Rodriguez. That was a sizable investment for their market size but not one that took too many people by surprise. They finally snapped Jordan Montgomery's extended free agent stay with a one-year, $25MM guarantee and an easily achievable vesting option that pushed their investment close to $50MM over two seasons.

The true shocker came last winter, when they emerged out of nowhere as the landing spot for Corbin Burnes, who wanted to pitch close to his Arizona home. He probably left some earnings upside on the table, but it still took a six-year commitment worth $210MM (with a net present value closer to $194MM after adjusting for deferred money).

They've added those big-name arms to an in-house starting pitching group that included Zac Gallen, Merrill Kelly and Brandon Pfaadt. Maybe they didn't match the depth of some other clubs, but their top six to seven starters look exceptionally formidable. This should be one of the best rotations in MLB.

And yet, for two years running, it hasn't been particularly close to that.

D-backs Sticking To Five-Man Rotation

By Steve Adams | February 13, 2025 at 9:56am CDT

The Diamondbacks’ surprise signing of Corbin Burnes further crowded a rotation that had at least six starters in the mix. While there’s been talk of a possible six-man rotation in Arizona since that Burnes deal, manager Torey Lovullo said at D-backs camp this week that team is not considering that at this point (link via Nick Piecoro of the Arizona Republic).

That leaves the Diamondbacks with seven starters for five spots: Burnes, Zac Gallen, Merrill Kelly, Eduardo Rodriguez, Brandon Pfaadt, Jordan Montgomery and Ryne Nelson. The first four are largely locked into place. Burnes and Gallen are Cy Young-caliber arms when healthy. Kelly has been a steady midrotation arm for the Snakes since signing out of the KBO in the 2018-19 offseason. Rodriguez’s first year in Arizona was marred by injury, but he’s signed three more years and has a lengthy track record.

Montgomery’s status in Arizona has been a talking point throughout the winter. The Diamondbacks signed him to a one-year, $25MM contract with a vesting $20MM player option for the 2025 season. The left-hander pitched enough to trigger that option but nowhere near well enough to decline it in favor of a return to the open market. Signing just days before Opening Day last season, Montgomery missed spring training, rushed through an accelerated ramp-up in Triple-A and never appeared to be himself. He pitched 117 innings but was rocked for a 6.23 earned run average with career-worst walk and strikeout rates.

D-backs owner Ken Kendrick called Montgomery’s performance out late in the season, publicly lamenting the role that he’d played in bringing the left-hander to his organization. “I brought it to (the front office’s) attention. I pushed for it,” Kendrick said in September. “They agreed to it. It wasn’t in our game plan. … And looking back, in hindsight, a horrible decision to have invested that money in a guy that performed as poorly as he did.”

Pfaadt, 26, would give the D-backs an upside arm at the back of the staff. The former top prospect hasn’t yet found his stride over a full big league season but has shown glimpses of the potential that made him so well regarded. He looked to have found his stride last year, logging a 3.98 ERA, 23% strikeout rate and 4.9% walk rate through his first 24 starts, but Pfaadt was hit hard in late August and for much of September. He mixed in one late-season gem — seven innings, one run, 12 strikeouts in Milwaukee — but even with that showing still posted an ERA north of 7.00 over his final eight starts. He finished the year at a 4.71 mark but did pile up 181 2/3 innings.

Nelson, who turned 27 in December, made 27 appearances this past season — 25 of them starts — and recorded 150 2/3 innings of 4.24 ERA ball. His 20% strikeout rate and 8.4% swinging-strike rate were below average (well below, with regard to the latter), but Nelson’s 5.4% walk rate was outstanding.

There are other options on the 40-man roster, but they’re likely to be viewed as depth candidates, barring a spring breakout. Yilber Diaz, Cristian Mena, Tommy Henry and Blake Walston are all on the 40-man roster and have all made their big league debuts, but they’d likely only be called upon in the event of multiple injuries — at least with the current roster construction.

Kendrick’s comments on Montgomery led to plenty of speculation about a potential trade of this winter, but no such deal has come to fruition. It’s still possible the D-backs could find a taker for a portion of the contract or swap him out for a comparably priced veteran on an underwater deal (e.g. Rhys Hoskins, Starling Marte), but for now, Montgomery will get a full spring buildup and look to bounce back from a dismal 2024 season.

If the D-backs can find some kind of trade that sheds a portion of the Montgomery money, any savings could be reallocated to other needs. Most notably, they’ve been in the market for a closer throughout the winter but have yet to add an established ninth-inning arm. Arizona’s payroll is projected for a franchise-record $195MM, per RosterResource. It’s not clear whether Kendrick is willing to push things further after already ponying up to sign Burnes (six years, $210MM), acquire Josh Naylor in a trade (one year, $10.9MM) and re-sign Randal Grichuk (one year, $5MM). Barring the signing of a veteran like David Robertson or Kyle Finnegan, the D-backs will look inward and lean on A.J. Puk, Justin Martinez and Kevin Ginkel as their top late-inning arms.

Diamondbacks Not Close To Any Pitching Trades

By Mark Polishuk | December 29, 2024 at 4:42pm CDT

The Diamondbacks’ surprise signing of Corbin Burnes added a new frontline arm to a rotation that was already operating at a surplus on paper.  Burnes joins Zac Gallen, Merrill Kelly, Eduardo Rodriguez, Jordan Montgomery, Brandon Pfaadt, and Ryne Nelson, giving the Snakes an enviably deep group of starting pitchers.  The D’backs had already been drawing trade interest in this group even before Burnes was added, but Nick Piecoro of the Arizona Republic reports that the Burnes signing wasn’t made with any other pitching swaps immediately on the horizon.

According to Piecoro, no “other deals [are] lined up or even close” involving Arizona’s pitchers, as the Diamondbacks will continue to take a measured view of the market.  A source tells Piecoro that the D’Backs will likely “spend the coming days fielding calls from teams still in the hunt for starters, including those that were in on Burnes.”  The D’Backs aren’t in any particular rush to complete a trade any time soon, as having more than a full rotation in place before New Year’s Eve gives the club plenty of time to figure out the best possible offer.

It also isn’t entirely out of the question that the Diamondbacks stand pat on their starters, especially if an injury emerges to a starter during their offseason training, or during Spring Training.  Kelly, Rodriguez, and Montgomery all missed significant time with injuries last season, so there is obvious value in having extra pitchers on hand should any more health issues create openings in the rotation.  Operating with a six-man rotation is also a possibility, in order to keep everyone healthy and fresh for what the D’Backs hope can be an extended run through the playoffs.

Given how the Burnes deal reportedly came together just within the last week when Burnes himself approached the D’Backs, it isn’t surprising that the signing wasn’t part of an immediate plan to re-model the pitching staff.  Such two-step transactions are usually hard to pull off, though the Diamondbacks were part of such a set of moves from the Guardians just last week — Arizona acquired Josh Naylor from the Guards, and Cleveland then signed Carlos Santana that same day to immediately fill Naylor’s spot as the everyday first baseman.

The fact that Burnes signed with a team that was seemingly already set for starting pitching gives GM Mike Hazen even more leverage in shopping his hurlers.  Such known Burnes suitors like the Orioles, Blue Jays, or Giants are still in need of pitching, to say nothing of the many other starter-needy clubs on the market that weren’t willing or able to meet Burnes’ asking price.

Nothing seems to have changed in terms of which starters are most prominently on Arizona’s trade block.  Gallen and Kelly are both free agents next winter but don’t seem likely to be dealt, as a team source told Piecoro that the team’s focus in on “trying to put the best team on the field in 2025.”  Nelson is controlled through the 2027 season and Pfaadt through the 2029 season, so the Diamondbacks would probably only move either if a longer-term asset (likely a position player) could be obtained in return.  The D’Backs might not mind moving the $66MM remaining on Rodriguez’s contract, but the club would certainly have to sell low and eat some of that money in the wake of E-Rod’s injury-plagued down year.

That leaves Montgomery as still the chief candidate to be dealt before Opening Day.  Montgomery’s trade value is also at a low ebb after his rough first year in Arizona, and his $22.5MM salary for the 2025 season.  Owner Ken Kendrick’s public criticism of Montgomery following the season only increased the probability that the left-hander would be pitching elsewhere next year, yet again, the Burnes signing gives the D’Backs some flexibility in this regard.  The Diamondbacks technically don’t have to trade Montgomery if an acceptable offer for another starter comes their way, and offers for Montgomery might improve if other teams become increasingly desperate to add pitching.

Diamondbacks’ Starters Drawing Trade Interest

By Steve Adams | December 5, 2024 at 10:58am CDT

As free agent starters begin to find new homes — Blake Snell, Yusei Kikuchi, Frankie Montas, Matthew Boyd and Kyle Hendricks have all signed in the past two weeks — interest in the Diamondbacks’ collection of rotation arms has “started to pick up,” general manager Mike Hazen tells Nick Piecoro of the Arizona Republic. The D-backs have at least six starters on the roster at present: Zac Gallen, Merrill Kelly, Eduardo Rodriguez, Brandon Pfaadt, Ryne Nelson and Jordan Montgomery.

Of the six, Montgomery is the most obvious trade candidate, following a rough 2024 showing and owner Ken Kendrick’s public, verbal thrashing of the player. In October, Kendrick openly lamented ever pushing his front office to sign Montgomery late in the 2023-24 offseason, calling it a “horrible decision to have invested that money in a guy that performed as poorly as he did” and “our biggest mistake this season from a talent standpoint.” Montgomery unsurprisingly exercised a $22.5MM player option even after being called out by Kendrick — a straightforward decision for a pitcher coming off an injury-shortened year with career-worst marks in ERA (6.23), strikeout rate (15.6%) and walk rate (8.3%).

For all the focus placed on Montgomery’s struggles last year, the other veteran lefty signed by Arizona last offseason also fell well short of expectations. Rodriguez signed a four-year, $80MM pact with the Snakes but was limited to just 10 starts after opening the season on the injured list due to a shoulder strain. He pitched 50 innings of 5.04 ERA ball while showing diminished life on his four-seamer and sinker. Rodriguez is owed $20MM for the coming season, $21MM in 2026 and $19MM in 2027. He’s also guaranteed a $6MM buyout on a $17MM mutual option for the 2028 season — an option that could automatically vest based on his innings tallies in 2026-27. While Montgomery’s contract is underwater, the three years and $66MM remaining on Rodriguez’s pact very likely make him even harder to unload.

Any of  the other four arms in Arizona’s rotation would be hard to pry loose. Ace Zac Gallen is a Cy Young contender when healthy, evidenced by fifth- and third-place finishes in 2022 and 2023 balloting. He missed about a month of action with a hamstring strain in 2024 and flashed worse command than usual (relative to his excellent standards, anyhow), but any team would love to have the right-hander. He’s projected by MLBTR contributor Matt Swartz to earn $14.1MM in his final season of club control before becoming a free agent next winter. Gallen is not being shopped, to be clear. Hazen even chuckled at the mere notion of Gallen being a prominent trade candidate in a mid-November appearance on Arizona Sports 98.7’s Wolf & Luke Show (2:35 mark). That’s unlikely to stop other teams from trying.

Kelly, like Gallen, is a free agent next offseason. He missed more than three months in 2024 with a shoulder strain but was generally effective when healthy, logging a 4.03 ERA with a slightly below-average 21% strikeout rate and a strong 6.3% walk rate. Arizona made an easy call to exercise a $7MM club option on Kelly for the upcoming season.

Nelson and Pfaadt are both controllable and thus quite valuable to the Snakes. The 26-year-old Nelson is under club control for four more seasons and just tossed 150 2/3 innings with a 4.24 ERA, 20% strikeout rate and outstanding 5.4% walk rate in 2024. Those numbers are skewed by a slow start, but from July onward, Nelson posted a 3.05 ERA, 24.8 K% and 5.0 BB% in 82 2/3 frames. He’s not yet eligible for arbitration.

Pfaadt, also 26, paced the D-backs with 181 2/3 innings and 32 starts. His 4.71 ERA doesn’t stand out, but his 24.3% strikeout rate, 5.5% walk rate, 3.61 FIP and 3.65 SIERA are all far more encouraging. He might’ve worn down a bit late in the season as he pushed through that new career-high workload, as his worst months were August and September. A disproportionate amount of the damage against Pfaadt this season came in one nightmare September outing, wherein the Brewers tagged him for eight runs in just 1 2/3 innings. Lopping off even that one start would cause his season-long ERA to drop by nearly 40 points. Regardless, the former top prospect is a 2025 breakout candidate when considering his pedigree and rate stats that far outpace his pedestrian earned run average. Of the arms on the big league staff, he’s probably the most difficult for another team to acquire.

There’s depth even beyond that sextet. Right-hander Drey Jameson will be back from 2023 Tommy John surgery next year. He’s already had some big league success. There are another five starters on the 40-man roster and likely ticketed for Triple-A, all of whom have minor league options remaining and at least a bit of MLB experience: Yilber Diaz, Slade Cecconi, Blake Walston, Cristian Mena and Tommy Henry. Few organizations boast a stockpile of arms so deep.

All of that is to say — it’s hardly a surprise that clubs are calling the D-backs about their starters. The same is true of their outfielders, as Hazen already acknowledged a couple weeks back. Piecoro writes that (naturally) Montgomery is both the likeliest to move and the pitcher whom the team would most strongly prefer to deal. Hazen stated that Kendrick’s comments regarding the left-hander have “zero” impact on the urgency to trade him, though there’s likely some public-facing lip service at play there.

Piecoro adds that the D-backs would be willing to take on another contract of some note in return for Montgomery (if said player filled a roster need) or perhaps pursue more of a traditional salary dump, where they shed as much of the contract as possible for little to no return. Of note, Hazen suggested that if he’s to ultimately move Montgomery in deal that is primarily rooted in salary relief, the trade would need to come together before the bulk of quality free agents come off the board: “At some point, it doesn’t make sense because your pivot moves are picking at the edges rather than getting somebody (who is more of a target).”
