Diamondbacks Sign Luken Baker To Minor League Contract
The Diamondbacks have signed first baseman Luken Baker to a minors deal, Just Baseball Media’s Aram Leighton reports. Baker qualified for minor league free agency at the end of the season, and he chose to test the open market rather than stick in the Dodgers’ organization.
A second-round pick for the Cardinals in the 2018 draft, Baker spent most of his career in the St. Louis organization before he was claimed off the waiver wire by the Dodgers in early August. Baker never saw any MLB playing time in Los Angeles, so his big league resume remains his 73 games played with the Cardinals over the 2023-25 seasons, with a .206/.317/.338 slash line and four home runs to show for 189 plate appearances.
This lack of production didn’t exactly merit more playing time, yet Baker was also blocked to some extent by the presence of Paul Goldschmidt, Willson Contreras, Alec Burleson, and others at first base. Baker is limited by his lack of defensive versatility, as he has played only first base and DH during his pro career. This made him an expendable piece even on a Cardinals team that is turning into a rebuild, as Baker is entering his age-29 season.
Baker got his first call-up to the majors on the strength of a huge season with Triple-A Memphis in 2023, when he hit .334/.439/.720 with 33 home runs over 380 PA. He followed that year up with a 32-homer campaign and a lesser (.231/.345/.535) slash line in Memphis in 2024, but his numbers continued to tail off, as Baker hit only .223/.335/.441 with 18 homers over 409 combined PA with the Cardinals’ and Dodgers’ top affiliates in 2025. While Baker’s numbers improved greatly after his move from Memphis to Oklahoma City, this may have had less to do with a change of scenery and more to do with the move to the pitcher-friendly Pacific Coast League.
The Diamondbacks’ Triple-A Reno club is also in the PCL, so it wouldn’t be a shock if Baker posts some numbers in 2026 that look pretty gaudy on paper. There’s no risk for the Snakes in seeing what Baker can do in at least a depth capacity, and if he can turn his raw power into any sort of consistent production at the big league level. In terms of the MLB roster, the right-handed hitting Baker could be a fit in a platoon situation with the lefty-swinging Pavin Smith at first base and DH, and the D’Backs may be hoping that Baker can follow Smith’s example as a late bloomer who didn’t start to break out in the majors until his late 20s.
Signing Baker to a non-guaranteed deal shouldn’t prevent the D’Backs from exploring more prominent right-handed bats for this role, such as former Arizona star Paul Goldschmidt. The Diamondbacks’ infield situation in general remains in something of a state of flux, as rumors continue to swirl that Ketel Marte could be traded, and that the D’Backs could be a dark horse suitor for Alex Bregman. Such moves wouldn’t necessarily impact the first base role, unless another first base candidate or right-handed bat was potentially brought on board as part of a Marte trade package.
Details On Ketel Marte’s No-Trade Protection
The seven-year contract extension Ketel Marte signed with the Diamondbacks last April included a five-team no-trade clause, which adds an interesting wrinkle to the trade rumors that have swirled around the former NLCS MVP in recent weeks. As reported by The Athletic’s Ken Rosenthal, the Athletics, Cardinals, Giants, Pirates, and Yankees are the five teams included on Marte’s current list, which can be updated every offseason.
There are any number of reasons why a player may include a particular team on a no-trade list, and it is worth noting that Marte could still ultimately approve a deal to any of these clubs. There is no obvious geographic link between the five teams, and while the Yankees were the only member of the group to reach the 2025 playoffs, the Giants, Pirates, and even the A’s are all looking to compete in 2026. The Cardinals are in rebuild mode, so it is safe to say they weren’t in the running to acquire Marte anyway.
Interestingly, the Pirates and Giants have been linked to Marte’s trade market. Now that Pittsburgh has landed Brandon Lowe from the Rays in yesterday’s big three-team swap, the Bucs may feel their second base needs have been addressed, though there is a world where Lowe could be a primary DH and Marte could still be brought aboard. Still, there’s such a hefty amount of money remaining on Marte’s contract that a trade to the budget-conscious Pirates always seemed like an imperfect fit, and Marte’s no-trade list might well underline his own reservations about joining a team with just one winning season in the last decade.
San Francisco has also topped the .500 mark only once in the last nine seasons, but the Giants have been much more willing to spend in their bid to return to consistent contention. While ownership is wary about making another long-term financial commitment, Marte’s deal could be viewed as a relative bargain, since he would land way more than $102.5MM on a six-year deal if he was a free agent this winter.
Second base is a need position for the Giants, though perhaps not as pressing as the club’s need for more rotation help. Making a big splash in acquiring Marte might not be as big a priority, in that case, plus there are the added obstacles of Marte’s no-trade protection and the Diamondbacks’ probable reluctance to move the All-Star to a division rival. San Francisco is considered to be one of the favorites to pry Brendan Donovan away from the Cardinals, so that might end up being the Giants’ big move to address the keystone.
The Giants and Pirates each play in pitcher-friendly ballparks, which might factor into Marte’s reasoning for including the teams on his list. Sutter Health Park is extremely hitter-friendly, yet it is fair to wonder if Marte just doesn’t want to play in a minor league stadium for at least the next two seasons while the A’s await the construction of their new ballpark in Las Vegas.
The A’s have a big hole at second base, and acquiring Marte would add another top-tier bat to a lineup that already includes Nick Kurtz, Brent Rooker, Tyler Soderstrom, Jacob Wilson, and Shea Langeliers. While the A’s have been a bit more willing to spend over the last year, Marte’s remaining salary would represent a new spending frontier for the traditionally low-payroll team. Hypothetically, Luis Severino could be included in a Marte trade as salary offset, but that assumes Arizona (who needs rotation help) has any interest in Severino in the wake of his uninspiring 2025 season.
The Yankees are the most interesting inclusion on Marte’s list, as one would think he would welcome a chance to join a perennial contender. Jazz Chisholm Jr. is already playing second base in the Bronx, but Chisholm is a free agent next winter, so Marte would represent a longer-term answer at the position. Purely speculatively, any kind of Diamondbacks/Yankees trade involving Marte could see Chisholm going the other way, to give Arizona a one-year stopgap at second or third base.
Re-signing Cody Bellinger is thought be the Yankees’ top offseason priority, though New York might pivot to other backup plans should Bellinger sign elsewhere. Landing Marte would certainly qualify as a substantial Plan B, yet his no-trade clause might make any potential trade a moot point.
Amidst all of the reports and speculation, it remains unclear if the Diamondbacks actually will trade away a star player who received such a lengthy contract extension less than a year ago. With Lowe now in Pittsburgh, however, one big second-base trade chip has been removed from the board, leaving other teams in need of keystone help perhaps more open to meeting Arizona’s demands for Marte. Beyond the Pirates and Giants, such teams as the Mariners, Rays, Red Sox, Blue Jays, Phillies, and Tigers have all reportedly shown some degree of interest in a Marte trade this winter.
D-Backs, Ildemaro Vargas Agree To Minor League Deal
The Diamondbacks are in agreement on a new minor league contract with infielder Ildemaro Vargas, reports Jon Heyman of The New York Post. The MAS+ Agency client returns to the organization after being outrighted off the roster at the end of the season.
Vargas has plenty of familiarity with the D-Backs. The veteran utilityman has played three separate big league stints and parts of six seasons in the desert. He got into 38 games this past season. Vargas hit .270 but only walked twice in 121 plate appearances, leading to a modest .292 on-base percentage. He’s a .249/.289/.357 hitter over parts of nine MLB seasons.
Defensive versatility has been Vargas’ calling card. The majority of his experience has been at shortstop, but he saw more action between second and third base this year. He’s entering his age-34 season and likely headed to Triple-A Reno. The D-Backs also added glove-first shortstop Jacob Amaya as non-roster infield depth earlier this offseason.
Diamondbacks Outright Bryce Jarvis
December 19th: The Diamondbacks announced today that Jarvis cleared waivers and has been sent outright to Triple-A Reno.
December 12th: The Diamondbacks announced that right-hander Bryce Jarvis has been designated for assignment. That’s the corresponding 40-man move for their signing of Michael Soroka, which is now official.
Jarvis, 28 this month, was Arizona’s first-round pick in the 2020 draft. The Snakes took him with the 18th overall pick and signed him with a $2.65MM bonus. He was a notable prospect for a bit but his stock has been dropping effectively since he was drafted.
He posted lackluster results as he worked his way up the minor league ladder, working mostly as a starter. In 2022, he made 25 Double-A starts but allowed 8.28 earned runs per nine in the process.
In 2023, he had a 5.08 ERA on the farm, slightly better but obviously still not ideal. Nonetheless, the Diamondbacks called him up to work out of the big league bullpen. He posted a 3.04 ERA there, although that number was misleading. His 9.8% walk rate was subpar and his 13% strikeout rate well below average. A tiny .162 batting average on balls in play and a high strand rate of 74.5% helped him out.
It was a similar story in 2024. Jarvis posted a 3.19 ERA but with subpar numbers under the hood. In 2025, his luck corrected, as he had a 5.73 ERA. He also continued to make starts at the Triple-A level, but with an 8.47 ERA in those.
Over the past three years, Jarvis has logged 105 big league innings. His 3.69 ERA doesn’t look bad but his 15.8% strikeout rate and 11.8% walk rate are both poor figures. He would have allowed more runs if not for a .251 BABIP and 76% strand rate. His 4.97 FIP and 5.11 SIERA are likely more accurate representations of the work he has done so far.
Jarvis has now been bumped off the roster in Arizona and will be in DFA limbo for a week at most. The waiver process takes 48 hours, so the Snakes could take five days to explore trades. Jarvis does have an option remaining, so it’s possible some club takes a shot on his draft pedigree and hopes for a breakout.

Diamondbacks Sign Merrill Kelly
The Diamondbacks officially announced a reunion with Merrill Kelly on a two-year contract with a 2028 vesting option. The Apex Baseball client is reportedly guaranteed $40MM. He receives a $2MM signing bonus and will make successive $17MM and $21MM salaries. If Kelly reaches 170 innings in 2027, he’ll lock in a $12MM salary for the 2028 season. If he reaches 185 innings in ’27, that ’28 guarantee will jump to $14MM. The D-Backs cleared a roster spot earlier by flipping Kyle Backhus to the Phillies.
The 37-year-old Kelly returns to the team with which he has spent nearly his entire major league career. Though initially drafted by the Rays in the eighth-round of the 2010 draft, Kelly made his big league debut with the Diamondbacks back in 2019 after a four-season stay in Korea as a member of the KBO’s SK Wyverns (now known as the SSG Landers). After a pedestrian rookie campaign in the majors where he pitched to a league-average ERA in 32 starts, Kelly managed to fashion a role for himself as one of the better mid-rotation arms in the majors.
Since the start of the 2022 campaign, Kelly has pitched to a 3.47 ERA in 108 starts. He’s struck out 23.1% of his opponents while walking 7.7% in that time, leaving him with a 3.81 FIP. Although a 4.03 SIERA and other so-so peripherals cast him as a step down from your prototypical front-end starter, the veteran has managed to remain a durable and productive rotation piece. Kelly particularly endeared himself to Arizona fans when he delivered a brilliant 2.25 ERA over 24 postseason innings during the club’s run to the World Series in 2023.
Amid a disappointing 2025 season where the Diamondbacks were ravaged by injuries to everyone from star closers Justin Martinez and A.J. Puk to newly-signed ace Corbin Burnes, the team engaged in a sell-off at trade deadline and shipped Kelly to the Rangers in exchange for a trio of pitching prospects. Kelly put up fairly pedestrian numbers across ten starts with the Rangers: a 4.23 ERA and near-matching 4.18 FIP across 55 1/3 innings of work.
Even while the veteran was in Texas, an offseason reunion with the Diamondbacks was already being speculated upon. Kelly spoke fondly of Arizona and expressed an openness to re-signing when asked about the possibility while the Rangers were visiting Chase Field in the season’s final few weeks. “Definite” interest in a reunion with Kelly was reported on Arizona’s side shortly before last week’s Winter Meetings, and now the sides have come together on a deal.
Turning to the deal itself, Kelly’s $40MM guarantee clocks in just ahead of the two years and $36MM MLBTR predicted for the right-hander when ranking him as the #25 free agent in this offseason’s Top 50 MLB Free Agents list. The Snakes were aggressive both in their offer and the timing of the deal; while the free agent market for position players and especially relievers has kicked into gear already, Kelly is just the third starting pitcher from MLBTR’s Top 50 to sign a contract this offseason. He joins Dylan Cease and Cody Ponce, both of whom received guarantees that slightly eclipsed MLBTR’s predictions.
Now that he’s set to return to Arizona, Kelly stands as the favorite to start for the Diamondbacks on Opening Day this year. He’ll join a rotation that already added Michael Soroka and will reunite with former teammates Eduardo Rodriguez, Brandon Pfaadt, and Ryne Nelson. Burnes could be a factor later in the season but is not expected to pitch until sometime in the second half after undergoing Tommy John surgery in June. While the team’s rotation certainly looks much more complete with Kelly back in the fold, bringing the right-hander back shouldn’t stop the team from pursuing other rotation additions after the club’s pitching staff finished 19th in the majors with a 4.29 ERA last year.
Of course, adding beyond this could prove to be easier said than done. The Diamondbacks are projected for a payroll just north of $171MM in 2026, according to RosterResource. That rises to north of $205MM for luxury tax purposes. GM Mike Hazen has suggested that, while Arizona’s payroll would likely be moving downward from its 2025 level, that would still leave the team with room to spend. The club spent $188MM on its payroll last season, however, meaning they currently sit less than $17MM from that mark.
Perhaps that leaves enough wiggle room to reunite with Paul Goldschmidt on an affordable one-year deal, a move the Diamondbacks have been said to be contemplating, but Kelly will surely go down as the team’s biggest expenditure unless an increase in payroll is approved or the team makes a trade that clears salary. To that latter point, the hot stove has been burning with Ketel Marte trade buzz in recent weeks. Moving Marte would certainly clear payroll off the books (and simultaneously add some young rotation options as part of the return), though Hazen has consistently downplayed the likelihood of a deal surrounding Marte actually coming together.
Ken Rosenthal of The Athletic first reported the Diamondbacks and Kelly were finalizing a two-year, $40MM deal. Nick Piecoro of The Arizona Republic reported the option specifics. David Brandt of The Associated Press had the salary structure.
Phillies Acquire Kyle Backhus
The Phillies announced that they have acquired left-hander Kyle Backhus from the Diamondbacks. Minor league outfielder Avery Owusu-Asiedu goes in the other direction. The move opens a 40-man spot for Arizona, which should allow them to make their agreement with Merrill Kelly official. Philly’s 40-man count goes from 37 to 38.
Backhus debuted for the Diamondbacks this past season. The 27-year-old scuffled to a 4.62 ERA across 32 appearances. Arizona’s ever-changing mix of late-inning options allowed Backhus to factor into high-leverage situations, and he recorded a pair of saves and 10 holds. He notched a one-out save in his final appearance with the big-league club, coaxing a flyout with the bases loaded to finish off a 6-4 victory in mid-September. He was sent back to Triple-A Reno shortly after.
Arizona added Backhus as an undrafted free agent in 2021. After posting middling results in a half-season of professional ball, he began to gain traction as a backend reliever. Backhus posted a hefty 34.5% strikeout rate between High-A and Double-A in 2022, earning three saves at each level. He locked down 10 more saves at Double-A the following season, leading to a promotion to Triple-A. Injuries limited Backhus to 35 2/3 innings in 2024. He received an invite to Spring Training this year, and while he didn’t break camp with the club, a strong couple of months at Reno saw Backhus get the call to Arizona.
Backhus is a sinkerballer who doesn’t light up the radar gun, but comes from a unique slot. Statcast had his arm angle at nine degrees, which was among the lowest in the league. Backhus also ranked in the 96th percentile for extension. Interestingly, the low arm slot and sinker-heavy approach didn’t lead to many ground balls. Backhus had a below-average 37.8% ground ball rate. He did a decent job limiting hard hits, but gave up an elevated amount of contact in the air to the pull side.
The Backhus addition comes on the heels of a trade that sent fellow lefty Matt Strahm to Kansas City. Strahm led the Phillies with 22 holds in 2025. Jose Alvarado will likely step into the lefty setup role vacated by Strahm, with Tanner Banks on hand as a lower-leverage southpaw option. Backhus will serve as a depth option who could step in if injuries or poor performance afflict Philly’s bullpen.
Philadelphia took Owusu-Asiedu in the ninth round of the 2023 draft. He delivered nine home runs and 17 stolen bases at Single-A in 2024, but it came with a .192 batting average and a 36.1% strikeout rate. Owusu-Asiedu was able to trim his strikeout rate to 24% between Single-A and High-A this past season. He also racked up 33 steals in 107 games.
The 22-year-old Owusu-Asiedu has experience at all three outfield positions. He made at least six starts in left field, center field, right field, and DH with High-A Hillsboro.
Diamondbacks Showing Interest In Alex Bregman
The D-Backs are among the teams that have expressed interest in Alex Bregman, as Bob Nightengale of USA Today was among those to report. Arizona seems to be a long shot to spend at this level but has a vacancy at third base.
Bregman is known to be a priority for the Red Sox. He opted out of his three-year deal with Boston after hitting .273/.360/.462 over 495 plate appearances. He made his third All-Star team despite suffering a quad strain that sidelined him between late May and the middle of July. That’s a testament to the strength of his first half. Bregman slashed .298/.380/.546 with 11 home runs over 53 games before the Break. His numbers dropped in the second half, as he hit .250/.341/.386 in his final 261 trips to the plate.
While Bregman’s power dropped late in the season, he showed his typically excellent plate discipline. He walked more often than he struck out even in his less impressive final few months. Bregman narrowly established a career mark with a 44.4% hard contact rate and remained the above-average hitter he was throughout his time in Houston. He’s no longer an MVP contender as he was at his 2018-19 peak, but Bregman is an annual threat for 25 homers with a .360 on-base percentage. He remains an above-average defensive third baseman and is revered for his clubhouse presence.
The D-Backs don’t have a clear answer at the hot corner. They traded Eugenio Suárez at the deadline. That theoretically opened the position for top prospect Jordan Lawlar, but his performance down the stretch was concerning. Lawlar hit .182 without a home run in 74 plate appearances. He also committed four errors (three on bad throws) over 76 innings. The D-Backs didn’t trust him defensively and limited him to mostly DH work in September until they’d been eliminated from playoff contention.
Lawlar came up as a shortstop but isn’t going to play there on a team with Geraldo Perdomo. He doesn’t have a path to second base playing time right now, though the D-Backs have fielded plenty of calls on Ketel Marte. They could give Lawlar a look in the outfield or dangle him as a trade chip for a young starter. For now, the likeliest course of action is to keep him at third base and hope that they can iron out his throwing woes in Spring Training.
It’d be very surprising to see Bregman wind up in the desert. The D-Backs are prioritizing the rotation even after agreeing to bring back Merrill Kelly on a two-year contract. Owner Ken Kendrick has already said payroll will come down from the approximate $195MM mark at which they opened the ’25 season.
RosterResource projects them for a $171MM payroll next season, so they’d either need to make an exception for Bregman or offload money in a trade. (They’d save $15MM in 2026 if they trade Marte for players making the league minimum.) The Diamondbacks are only one offseason removed from pulling off a free agent shocker, as almost no one saw them signing Corbin Burnes — who, like Bregman, is a client of the Boras Corporation — to a $210MM contract before it happened.
Burnes, who lives in Arizona, signed with the Diamondbacks largely because of family considerations. Bregman is a New Mexico native who grew up as a Diamondbacks fan, notes Nick Piecoro of The Arizona Republic. As Piecoro points out, the D-Backs (under the previous front office) had an opportunity to draft Bregman with the first pick in 2015. They went with Dansby Swanson instead, allowing the Astros to grab Bregman at #2 overall.
Diamondbacks Sign Isaiah Campbell To Minor League Deal
The Diamondbacks have signed right-hander Isaiah Campbell to a minor league deal, according to his transactions tracker at MLB.com. The ACES client has been assigned to the Triple-A Reno Aces but will presumably receive an invite to big league camp in spring training.
Campbell, 28, has appeared in each of the past three big league seasons. Suiting up for the Mariners and Red Sox, the righty has thrown 43 innings in the majors, allowing 5.65 earned runs per nine. His 21.9% strikeout rate and 8.3% walk rate are close to average while his 47.7% grounder rate is a few ticks better than par. His .341 batting average on balls in play and 66.6% strand rate are both to the unfortunate side, so metrics like his 4.34 FIP and 3.89 SIERA are a bit more optimistic than his ERA.
Only 7 2/3 of those innings came in 2025, as he spent most of the season with Triple-A Worcester. He logged 57 2/3 at that level this year with a 3.90 ERA. His 18.1% strikeout was a bit on the low side but he got grounders on 50.5% of balls in play. He averages in the mid-90s with his four-seamer and sinker but throws his slider more than half the time. He added a curveball in 2025 and mixed that in sporadically.
Campbell exhausted his final option season this year and will be out of options going forward, which will make it harder for him to hold a roster spot. The Sox outrighted him off their 40-man in October and he was able to elect free agency.
The bullpen was a big problem for the Snakes in 2025. They had planned for A.J. Puk and Justin Martínez but both were felled by UCL surgeries and other guys dealt with injury problems as well. Their relief corps had a collective 4.82 ERA this past season, which was better than just the Angels, Rockies and Nationals.
They will surely make some more moves to upgrade their bullpen before Opening Day but Campbell gives them some extra non-roster depth for now. He has just over a year of MLB service time. If he can earn a roster spot and hold it, he can be cheaply retained beyond the 2026 season.

Mariners, Giants “Front-Runners” For Brendan Donovan
The Mariners and Giants have emerged as front-runners in the sweepstakes for super-utility man Brendan Donovan, according to a report from Katie Woo of The Athletic. Woo added that both clubs are also engaged with the Diamondbacks on Ketel Marte.
Both Seattle and San Francisco have previously been reported to have interest in Donovan’s services, which Woo notes the Cardinals are seeking multiple top prospects in exchange for. With that being said, they were often mentioned as just two of many teams interested in the versatile infielder; Donovan’s market has been said to encompass more than half the league, with the Pirates, Royals, Guardians, and Astros standing among the other teams that have been connected to him this winter.
That makes the Mariners’ and Giants’ “front-runner” status a notable shift in the status quo, and Woo goes as far as to mention specific prospect names being discussed with both clubs. In talks with Seattle, Woo reports that the Cardinals have discussed top pitching prospect Jurrangelo Cijntje and outfielder Lazaro Montes. The pair are Seattle’s #7 and #3 prospects, respectively, according to MLB Pipeline. In talks with the Giants, Woo writes that the names of infielder Gavin Kilen and southpaw Carson Whisenhunt have come up. Kilen is San Francisco’s #2 prospect per Pipeline, while Whisenhunt ranks #7.
Cijntje has garnered some buzz around the baseball industry due to his status as a switch pitcher who throws from both the right and left sides. He’s a more well-regarded pitcher from the right-hand side, touching the upper 90s with his right arm but being relegated to the low 90s with his left. In his pro debut in 2025, Cijntje pitched to a 3.99 ERA overall across the High-A and Double-A levels but actually got better after his promotion. In seven starts at Double-A, Cijntje turned in a 2.67 ERA across 33 2/3 innings of work with a 25.5% strikeout rate and an 11.0% walk rate.
Montes entered the 2025 season as a consensus top-100 prospect in the sport but scuffled a bit after being promoted to the Double-A level. He hit a solid but unspectacular .213/.319/.433 in 64 games at the level with a 30.5% strikeout rate. That’s hardly exciting production, but some of those struggles can be forgiven considering he was one of just four hitters under the age of 21 to reach 200 plate appearances in the Texas League last year, joined by Sebastian Walcott, Walker Jenkins, and teammate Michael Arroyo.
Kilen was San Francisco’s first-round pick in the 2025 draft. As a result, he has just ten professional games under his belt where he hit a lackluster .205/.279/.282. With that said, the University of Tennessee product hit an incredible .357/.441/.671 in his final collegiate season and was roundly viewed as a plus contact hitter despite questions about his power potential and ability to handle shortstop at the big league level.
As for Whisenhunt, the 25-year-old already made his big league debut earlier this year with a 5.01 ERA across five starts. While it was hardly an exciting pro debut, Whisenhunt did manage to post a 4.41 ERA in 21 starts in Triple-A’s Pacific Coast League despite the extremely unfriendly environment for pitchers at that level. He profiles as a possible mid-rotation arm with a profile carried by a plus-plus changeup.
Of course, it’s possible that these are only a handful of prospects St. Louis is discussing with the two suitors. It should also be noted that Donovan is far from the only avenue either club is pursuing for their vacancy at second base. The Mariners had been in rather public pursuit of a reunion with Jorge Polanco until he signed with the Mets yesterday, but they’ve still be connected to Marte in addition to Donovan. Woo suggests that Polanco’s departure could leave the Mariners more motivated to make a deal in the coming days, and perhaps that could indicate that Seattle is the more aggressive suitor of the two.
Woo describes the Giants, by contrast, as “exploring all options” as they look to upgrade over Casey Schmitt and Tyler Fitzgerald at second base. In addition to Marte, Brandon Lowe is also known to be available on the trade market while teams have also inquired after Cubs infielder Nico Hoerner. The infield market in free agency is tilted more towards the left side, but Alex Bregman has expressed a willingness to play second base in the past, shortstop Ha-Seong Kim has experience at the position, and Bo Bichette has long been viewed as a potential candidate to move off shortstop at some point. San Francisco hasn’t been directly tied to any of those players, of course, but all stand out as at least plausible acquisitions to be made by a team searching for second base help.
Diamondbacks Sign Michael Soroka
December 12th: The Diamondbacks made it official today, announcing they signed Soroka to a one-year deal with a mutual option. Fellow righty Bryce Jarvis has been designated for assignment as the corresponding move.
December 8th: The Diamondbacks and free agent right-hander Michael Soroka are in agreement on a one-year deal that will reportedly pay the ISE Baseball client a guaranteed $7.5MM. Soroka can tack on an additional $2MM worth of incentives. The deal is pending a physical. Once complete, he’ll be penciled into the team’s rotation.
Soroka, still just 28 years old, is already signing the second free-agent contract of his career. He inked a one-year, $9MM deal with the Nats last offseason after an uneven year with the White Sox, wherein he struggled immensely as a starting pitcher before posting huge numbers as a reliever down the stretch. Washington plugged Soroka back into a starting role in 2025, eventually flipping him to the Cubs at the trade deadline. Soroka posted a middling 4.52 ERA in 89 2/3 innings (17 starts, six relief appearances) but continued to intrigue with sharp rate stats: 25.1% strikeout rate, 7.7% walk rate, 44.1% ground-ball rate.
Arizona is in need of help both in the rotation and in the bullpen, so even though Soroka is bound for the starting staff, he could be a fallback in the bullpen if the initial plan doesn’t work out. For now, he’ll join the trio of Ryne Nelson, Eduardo Rodriguez and Brandon Pfaadt as one of manager Torey Lovullo’s starters.
It still wasn’t that long ago that Soroka looked like one of the game’s most promising young arms. The 2015 first-round pick ranked as one of baseball’s top prospects prior to his debut with Atlanta, and the first two seasons of his career more than justified that billing. In 200 1/3 innings from his late-2018 callup through the end of the 2019 season, Soroka pitched to a sparkling 2.79 earned run average. His 20% strikeout rate was below-average, but he compensated for that with an excellent 5.9% walk rate, a 50.2% grounder rate and plenty of weak contact.
Injuries decimated the next several years of Soroka’s career and eventually pushed him out of the Braves’ plans. He’s twice torn his Achilles tendon and also missed time due to multiple shoulder injuries and a biceps strain. Soroka hasn’t reached even 100 innings in a major league season since that outstanding 2018-19 run; in fact, he’s pitched only 215 1/3 big league innings total since that time — just 15 more than he pitched in that initial MLB run.
Soroka will be one of multiple additions in general manager Mike Hazen’s rotation. The D-backs entered the offseason in dire need of pitching depth. Of the aforementioned trio of starters, only Nelson (3.39 ERA, 154 innings) posted quality bottom-line results last year. Both Rodriguez and Pfaadt posted ERAs north of 5.00, though each (Pfaadt in particular) was viewed more favorably by fielding-independent metrics.
Diamondbacks owner Ken Kendrick has already indicated that payroll will decline after last year’s mark topped $200MM for the first time in franchise history. However, he’s also made clear that the team is fully intent on striving to contend despite that reduction. It’s not clear exactly where the ultimate budget lies, but Hazen and his staff should have plenty of spending room even with the budget scaling down. The addition of Soroka pushes next year’s projected payroll to just over $151MM, per RosterResource.
Arizona has also been looking into a reunion with righty Merrill Kelly, whom they traded to the Rangers in July ahead of his free agent departure this offseason. There’s mutual interest there, though Kelly’s annual salary will likely more than double what Soroka just commanded. Pete Fairbanks is a known target on the bullpen side of things, though he’s surely just one of many. The D-backs are also at least hearing out other clubs who inquire on star second baseman Ketel Marte, though a trade is seen as unlikely, and they’re listening to offers on lefty-swinging outfielders Alek Thomas and Jake McCarthy.
Suffice it to say, it’ll be a busy few days for the D-backs in Orlando at this week’s Winter Meetings, though it’s unlikely the check off every item on their to-do list before MLB’s premier offseason event concludes.
Jesse Rogers and Jeff Passan of ESPN first reported the one-year agreement between the two parties. Nick Piecoro of the Arizona Republic first reported the salary terms, incentives and Soroka’s role.
