Seattle Mariners Trade Targets: Upgrading the Roster for a World Series Run (2026)

The Seattle Mariners' Offseason Dilemma: Balancing Youth and Contention

As the Winter Meetings kick off in Orlando next week, all eyes will be on the Seattle Mariners. They’ve already made a splash by retaining Josh Naylor, a cornerstone of their lineup, but the real work is just beginning. With 30 front offices, countless agents, and even some players converging in one place, this is the perfect storm for deal-making. But here’s where it gets tricky: the Mariners are walking a tightrope. They’re a team that came within a hair’s breadth of the World Series last season, yet they’ve lost key contributors like Eugenio Suárez and Jorge Polanco. The question now is, how do they improve without disrupting the chemistry that got them so close?

The Balancing Act: Youth vs. Experience

The Mariners’ challenge is twofold. First, they need to strengthen their infield, right field, and bullpen to compete in what promises to be a tougher American League. Second, they must find a way to integrate their promising young talent—players like Colt Emerson, Cole Young, Ben Williamson, and Harry Ford—without rushing them into roles they’re not ready for. It’s a delicate dance, but one that could define their season. And this is the part most people miss: how do you blend the raw potential of youth with the proven reliability of veterans?

Trade Targets: Who Could Be Wearing Mariners Blue?

Jerry Dipoto, the Mariners’ president of baseball operations, is no stranger to the trade market, adhering to a “draft, develop, and trade” philosophy. So, who might be on their radar? Let’s break it down, focusing on position players who could make an immediate impact.

1. Ketel Marte: The Upgrade at Second Base/Shortstop/Outfield
Marte is the kind of player who could transform the Mariners into AL favorites. Think of him as a better version of Jorge Polanco—a switch-hitter who can play second base, shortstop, and even outfield, but with superior numbers across the board. Yes, he’s pricier and would require a hefty package of prospects, but his health, defense, and projected OPS (over 100 points higher than Polanco’s, according to Baseball Reference) make him a tantalizing option. If Polanco is holding out for a big payday, Marte could be the upgrade Seattle needs. But here’s the controversial part: is it worth mortgaging the future for a player who might not guarantee a World Series berth?

2. Jarren Duran or Steven Kwan: The Leadoff Solutions
These two outfielders are cut from the same cloth. Both are excellent defenders, ideal for the spacious T-Mobile Park, and both can hit leadoff with high averages and on-base percentages. Duran brings more power and speed, while Kwan is the steadier, more proven option. Either could slot into right field, allowing Dominic Canzone to DH, or even replace Randy Arozarena in left field. But which one fits better? Duran’s upside is higher, but Kwan’s consistency might be more valuable. And this is where it gets interesting: could the Red Sox, desperate for pitching, be willing to part with one of these assets?

3. Brandon Lowe, Brendan Donovan, or Jake Cronenworth: The Second Base Conundrum
If Marte isn’t an option, the Mariners could look to these three second basemen. Lowe is the power hitter, averaging 34 home runs per 162 games, but his defense and on-base percentage are declining. Cronenworth is a solid contact hitter but has struggled since his All-Star seasons in 2021-22, and his $12 million annual salary raises questions about value. Donovan, the youngest of the trio, offers the best blend of average, doubles power, and plate discipline, but he’d likely cost the most in a trade. The wildcard? Donovan’s versatility—he can play third base, too, providing flexibility if Polanco re-signs. But is it worth investing in a second baseman when young infielders are knocking on the door?

4. Alec Bohm: The Questionable Fit
Let’s be honest: Bohm isn’t the most exciting option. His power has waned, his defense is questionable, and his clubhouse fit in Seattle is uncertain. Yes, he could be acquired cheaply, given his declining numbers and impending free agency, but does he really move the needle? Compared to the other names on this list, Bohm feels like a consolation prize. But here’s a thought-provoking question: could a change of scenery reignite his career, or is he a risk not worth taking?

The Bigger Picture: Building a Contender
The Mariners’ offseason moves will shape their future. They need to strengthen their roster while leaving room for their young stars to grow. It’s a high-wire act, but one that could pay off in a big way. So, what do you think? Which of these players would you target? And more importantly, how do you balance the need for immediate improvement with the long-term development of young talent? Let’s hear your thoughts in the comments—this is one debate that’s sure to spark some fireworks.
