The Seattle Mariners enter the offseason with momentum and a clear goal: push past last year’s near-miss and make a deeper run in 2026. With rotation pieces, bullpen firepower and the return of Josh Naylor, one remaining free agent could be the missing piece that turns a talented roster into a true postseason threat.
Why Seattle still needs a middle-of-the-order slugger
The Mariners’ core shows balance: young stars, veteran pitching and a bullpen that can close games. Yet the lineup is still short of consistent, game-changing pop at the hot corner. Seattle’s front office understands that in October, power and run production matter as much as starting pitching.
- Protection for the top of the lineup: Julio Rodríguez’s presence is magnified when hitters behind him drive in runs.
- Depth for a long season: Injuries or slumps expose teams without established bats in key spots.
- Playoff insurance: Managers prefer proven producers in late-inning, high-leverage matchups.

Signing a big bat at third base would give opposing rotations one more assignment to plan for. That kind of pressure changes how pitchers approach the whole lineup.
What Eugenio Suárez brings after the 2025 campaign
Eugenio Suárez arrived in Seattle midseason and showcased the type of power that can swing series. Across the entire 2025 season he launched 49 home runs and drove in a career-high 118 runs. Those totals put him among the MLB’s better run producers.
With the Mariners specifically, Suárez struggled to find consistent contact, but his power remained a constant. In 53 games with Seattle he delivered 13 homers and 31 RBIs. While the batting average dipped, the ability to change a game with one swing stayed intact.
Power-hitting third basemen are rare, and Suárez’s ability to clear fences instantly upgrades the middle of the lineup. For an offense built around a dynamic leadoff man and a young center fielder, that bolt of power can be decisive.
How Seattle’s internal options compare
Ben Williamson made his major-league debut in 2025 and earned regular time at third. Over 85 games he hit .253, stole five bases, and logged 21 RBIs. Williamson’s youth and upside matter for the long term.
But the playoff window the Mariners are chasing favors proven veterans at key spots. A lineup that pairs Williamson’s defense and athleticism with an established slugger could balance present needs and future development.
- Williamson: promising, controllable, needs reps.
- Suárez: established power, proven run production, immediate impact.
Additionally, the departure of Jorge Polanco to the Mets leaves infield depth thinner. That makes addressing third base a practical roster priority this offseason.
Fit with the current lineup and clubhouse
The Mariners already boast several cornerstone bats: Julio Rodríguez, Cal Raleigh and Josh Naylor. Adding Suárez plugs another power lane, forcing opponents to navigate consecutive threats. That lineup construction can increase run expectancy and produce more multi-run innings.
Beyond stats, Suárez has tasted the team environment and the postseason push. His familiarity with the clubhouse and coaching staff could shorten any adjustment period. Clubs weighing signings value players who can integrate quickly, especially when time to build chemistry is limited before spring training.
The combination of proven power and prior experience in Seattle gives Suárez an edge among possible third-base targets.
What the market means for Seattle’s plans
Any team needing production at third base will examine Suárez. The market could get competitive, but the Mariners have persuasive selling points: a ready-to-win roster, a solid pitching staff, and clear postseason aspirations.
Contract projections likely factor in age, durability and offense-versus-contact profile. Baseball executives will balance guaranteed years with performance incentives. For Seattle, the decision is strategic: invest now for a shorter-term boost or prioritize internal development and payroll flexibility.
Key takeaways for front office strategy
- Prioritize a deal structure that mitigates batting average risk but rewards long-term power.
- Consider platoon or rotation options to keep Suárez fresh against left-handed pitching.
- Use depth moves to protect against injury after adding a veteran bat.
Signing Eugenio Suárez would signal Seattle’s intent to compete immediately and build around a potent core for 2026. The club’s recent re-signing of Josh Naylor shows a willingness to be active in free agency. Suárez could be the next domino in a targeted offseason plan designed to convert regular-season success into deeper playoff runs.
