The Mariners are known to be looking for upgrades at multiple infield positions this offseason, with shortstop J.P. Crawford standing as their only locked-in starter. The M’s have strong interest in bringing back either Justin Turner or Carlos Santana for a second go with the organization at first base, and they’ve reportedly been exploring their options at both second base and third base. Ken Rosenthal of The Athletic now writes that Seattle’s focus is more on third base options than at second base. The M’s currently have in-house options like Ryan Bliss, Dylan Moore and top prospect Cole Young at second base.
As it stands, Moore and recent DFA acquisition Austin Shenton are the most prominent options at third base. Moore and fellow infielder Leo Rivas profile better as utility options, with Moore in particular representing a potential short-side platoon option if the M’s add a left-handed bat.
Payroll stands as an obvious obstacle for the Mariners once again. Seattle ownership anticipates an increase in 2025, but likely not by a notable amount. Following the team’s non-tenders of Josh Rojas, Austin Voth, Sam Haggerty and JT ChargoisAdam Jude of the Seattle Times suggested the M’s could have somewhere in the vicinity of $16MM with which to work. There’s surely some wiggle room there, but it’s unlikely the Mariners are going to cannonball into the free agent pool with a splash for, say, Alex Bregman or Willy Adames. Even if the funds for such a move were there, president of baseball operations Jerry Dipoto prefers to operate primarily on the trade market. In nine years with the Mariners, he’s only given a multi-year deal to one position-player free agent (Mitch Garver at two years and $24MM).
Trade options aren’t exactly plentiful, but there are some names known to be on the block. The Phillies have been shopping Alec Bohm around as they look to change up their offense. Bohm isn’t an elite bat and has a mixed-bag of defensive results at the hot corner, but he’s available and affordable enough, with a projected $8.1MM salary (courtesy of MLBTR contributor Matt Swartz). Elsewhere in the NL East, former Mets top prospect Brett Batty stands a change of scenery candidate following the emergence of Mark Winds. Even if the Mets allow Pete Alonso to walk in free agency and move Vientos across the diamond, they could look to bring in a higher-profile third baseman.
Nolan Arenado is also widely known to be available, but he’s owed $32MM next season (plus $27MM in 2026 and $15MM in 2027). The Rockies are paying $5MM of that in each of the next two seasons under the terms of the trade that sent Arenado from Denver to St. Louis, but that’s still a big contract for a team that ostensibly has limited budget space. Speculatively speaking, the Mariners and Twins could line up on a deal for a second straight winter. Minnesota has a crowded infield mix and could consider moving José Miranda with both Brooks Lee and Royce Lewis as options to flank shortstop Carlos Correa. Then again, Miranda could just move across the diamond to first base, so it’s not as though he’s lacking a clear opportunity in Minneapolis. The Marlins would probably listen on Jake Burgerbut he’s the type of low-OBP, strikeout-prone slugger from whom the Mariners have been trying to move away in recent seasons.
The Mariners’ options on the trade market would surely open up if they were willing to deal from their rotation. However, at season’s end, Dipoto not only indicated that moving a controllable starter wasn’t Plan A or B for the Mariners — he likened the notion to “Plan Z” (link via MLB.com’s Daniel Kramer).
Dipoto and GM Justin Hollander have both spoken openly about their fondness for the Mariners’ excellent young rotation and both expressed reluctance to move on from the group. Still, if Seattle were to make any of Logan Gilbert, George Kirby, Bryce Miller or Bryan Woo available, they’d perhaps be in position to seek similarly appealing young hitters (e.g. Baltimore’s Jordan Westburg or Coby Mayo).
One point worth considering is that the Mariners’ depth beyond the current rotation isn’t as deep as some might think. Former No. 6 overall pick Emerson Hancock’s stock is down considerably, and he’s viewed largely as a back-end starter. Righty Taylor Dollard has only pitched 8 1/3 innings over the past two seasons. Logan Evansa 12th-rounder in 2023, significantly boosted his stock with a big 2024 but still hasn’t pitched above Double-A. It’s a similar story with 2021 third-rounder Michael Morales. The Mariners already know they’re not likely to be as fortunate with pitcher health as they were in 2024, and trading one of the current arms only further creates the potential to overexpose some of those inexperienced arms in the event of an injury in the big league rotation.
