After an early burst of activity, the Seattle Mariners\u2019 offseason has slowed considerably, leaving several roster questions unresolved. Yet as the trade market evolves and roster depth continues to take shape, Seattle remains active across multiple fronts. Here\u2019s a look at the latest developments involving trade talks, bullpen moves, and international signings shaping the Mariners\u2019 offseason.<\/p>\n
The options for the Mariners to add impact bats to the lineup are dwindling. With the Arizona Diamondbacks pulling Ketel Marte<\/a> off the table, Nico Hoerner<\/a>\u00a0unlikely to be moved, and Willi Castro<\/a> landing with the Colorado Rockies, the market has thinned considerably. That reality has only increased the leverage surrounding Brendan Donovan<\/a>, whose name continues to surface in discussions as the St. Louis Cardinals look to maximize his trade value this offseason.<\/p>\n ESPN\u2019s Jeff Passan reported earlier this week that the Giants were pursuing both Donovan and Hoerner, with Seattle also identified as a potential suitor<\/a> for Donovan and Marte at various points. As the market has narrowed, that interest has only become more concentrated. Even without explicit mention of the Mariners, the reporting highlights how narrow the market has become. This will only intensify as we move closer to spring training, and Donovan continues to dominate trade discussions.<\/p>\n The San Francisco Giants are aggressively pursuing a second baseman and have been engaged with Chicago on Nico Hoerner and St. Louis on Brendan Donovan, sources tell ESPN. An infield of Matt Chapman, Willy Adames, Donovan or Hoerner and Rafael Devers would be among MLB’s best.<\/p>\n \u2014 Jeff Passan (@JeffPassan) January 13, 2026<\/a><\/p><\/blockquote>\n\n
