Mariners Pursue Offseason Trades for All-Star Infielders

Mariners Set Their Sights on All-Star Infielders

The Seattle Mariners have emerged as major players in the offseason trade market, particularly as they look to bolster their infield following the departures of key players Jorge Polanco and Eugenio Suarez, both of whom are free agents. After pushing the Toronto Blue Jays to a Game 7 in the ALDS, it's clear that the Mariners aspire to build on their success and compete aggressively in the 2026 season.

Names to Watch

Recent reports from MLB Network's Jon Morosi have notably linked the Mariners with two All-Star infielders: Ketel Marte of the Arizona Diamondbacks and Brendan Donovan of the St. Louis Cardinals. Each brings a unique skill set that could help fill the void left by Polanco as the Mariners look to finalize their roster.

“Another team involved used to have Ketel Marte—the Seattle Mariners,” Morosi observed. “The Mariners are very much involved in this infield trade market between Marte and Brendan Donovan.”

Marte, who previously played for Seattle in 2015 and 2016, showcased his talent during his short tenure, despite appearing in only 176 games. Landing him again would mark a significant return, potentially rejuvenating his career in the city where he once made an impact.

Assessing the Prospects

With both Marte and Donovan coming off impressive seasons, their addition could solidify the Mariners' infield significantly:

• Ketel Marte: A seasoned second baseman, Marte concluded the 2025 season with an impressive .893 OPS, solidifying his stance as a formidable player both offensively and defensively.
• Brendan Donovan: Slightly younger at 29 years old, Donovan has been less established but comes off a solid .775 OPS season. His versatility as a second baseman and outfielder offers an intriguing option.

Ultimately, either player could step in as an ideal replacement for Polanco, depending on the Mariners' approach in negotiations. While Marte may offer immediate star power, Donovan could present a more budget-friendly option while maintaining strong performance levels.

Future Implications for the Mariners

As the Winter Meetings unfold, it's critical for the Mariners to act decisively in the trade market. Reports indicate their active involvement suggests a clear strategy aimed at enhancing their competitiveness. If they succeed in acquiring either of these All-Star infielders, it could pivotally reshape the Mariners' roster, enabling them to carry forward the momentum from last season's playoff run.
