The Mariners have a lot to fix, and Mauricio Dubón checks more than one box.
Seattle finished the 2026 season third-worst in scoring and dead-last in team fielding run value, so the shopping list is obvious: help the offense, clean up the defense, and find at least one right-handed bat. Adam Jude of The Seattle Times also pointed to the need for a left-side infielder to pair with Colt Emerson. Dubón fits that ask cleanly, and then some.
The appeal starts with the glove. Dubón just won his third Gold Glove in four years, and he brings plus defense at multiple positions.
He’s the kind of utility player teams dream about, not just because he can move around, but because he can do it well. Over eight major league seasons, he has logged big league time at every infield and outfield spot.
His Range (OAA) has usually sat in the top decile, including the 99th percentile as recently as 2025.
That versatility would make plenty of sense for Jerry Dipoto, who has long shown a fondness for utility players. Jude’s reporting says the Mariners are looking for a veteran infielder who can handle either third base or shortstop, and Dubón gives them that flexibility without limiting him to one lane.
There’s enough on the bat, too, even if he’s generally viewed as an average-ish right-handed hitter. Dubón owns a solid career .740 OPS against left-handed pitching, which matters for a Mariners lineup that struggled in that split throughout 2026.
He also showed strong plate discipline last season, ranking in the 95th percentile in K%. On top of that, he set personal bests with 12 home runs and 73 RBI.
If Seattle is going to live with some offensive limitations, a glove like Dubón’s makes that easier. The Mariners would still need another right-handed bat, but a player who can stabilize multiple spots has real value. MLB Trade Rumors projects Dubón for a two-year, $18 million deal, a number that fits within what the Mariners could reasonably budget for in 2027.
Dubón’s 2026 season was the best of his career, and it came in his first year with the Braves. He posted a career-high 2.4 fWAR and played 153 regular season games, the most he’s ever logged in a single season. That kind of workload says plenty about how much Atlanta leaned on him.
Even so, he’s still a free agent, and the prediction from MLB Trade Rumors’ Steve Adams, Anthony Franco and Darragh McDonald is that he will re-sign with the Braves for next season. That doesn’t mean Seattle should back off.
The Mariners have enough holes to justify pursuing a player who can cover several of them at once, and Dubón’s profile makes a lot of sense for what they need. He could fit next to Emerson on the left side of the infield, and there’s also a case for him and Brendan Donovan as a roving platoon.

Mariners Outfield Pursuit Could Define Their Entire Offseason
The Mariners are heading into the offseason with a clear need in the outfield, and Seiya Suzuki has quickly emerged as one of the names to watch. Seattle is reportedly interested in the former Cubs outfielder, a player who fits the kind of impact bat the club has been hunting, and the team is even expected to lean on Ichiro Suzuki as part of its recruitment effort. With both Suzuki and Randy Arozarena having declined qualifying offers, the market is shaping up to be crowded for top-tier outfield help.
For Seattle, the timing matters as much as the target. The club is working with an estimated $30-35 million in payroll space, which gives it room to be aggressive but not reckless in a winter that could determine how the lineup looks for years to come. Arozarena is expected to draw plenty of attention elsewhere, and the Mariners appear unlikely to bring him back, which only raises the stakes on finding the right answer in free agency. [Read more 🡒]
Mariners Face A Third Base Decision That Could Define Their Offense
The Mariners offseason search for offense is already circling one of the most important decisions on the roster, and it starts at third base. Seattle wants more impact at the position, but the front office also has to weigh defense, fit and how much room it wants to leave for the next wave of young talent. That makes the market complicated, even before the club gets into the familiar names that could be available.
Eugenio Surez, Alec Bohm, Edmundo Sosa and Brendan Donovan are all part of the conversation, each bringing a different blend of power, glove work and versatility. The wrinkle is that Seattle is also sorting through what comes next at shortstop, which only adds to the pressure to get the infield alignment right. However the Mariners handle it, this is the kind of decision that could shape not just the lineup, but the way the offense is built for the next few seasons. [Read more 🡒]
Mariners Offseason Focus Just Shifted To A Costly 2026 Problem
At the MLB general manager meetings, Jerry Dipoto made it clear the Mariners are entering the winter with a familiar but urgent checklist: find more offense, and just as importantly, tighten up a defense that slipped badly in 2026. Seattle finished last in several defensive metrics, and the problems were especially pronounced on the left side of the infield and outfield, where the club is staring at major turnover with Randy Arozarena and J.P. Crawford both expected to depart in free agency.
That reality has pushed the front office toward players who can help stabilize the run prevention side of the roster, even if the market may not make that easy. Seattle has been linked to defense-first options such as Mauricio Dubn, Daulton Varsho, Ian Happ and right fielder Seiya Suzuki, as the Mariners try to balance lineup upgrades with the kind of glove work that can keep a good pitching staff from carrying too much of the load again.
