Another potential win-win situation is out west in Seattle. The Mariners should have made it to the postseason and appeared destined to do that to the extent that Twins fans were prepping themselves for a Wild Card matchup against them. That didn't end up happening, and now the Mariners are the third-best team in a division that sent its top two teams to the ALCS -- with the Texas Rangers winning the World Series.
There's a lot of offensive talent in Seattle, and it makes sense to add Polanco to a lineup that already has guys like Julio Rodriguez, Jarred Kelenic, and Cal Raleigh. There's a bit of a hole at second base that Polanco could fill, but his veteran leadership would be one of the biggest additions he brings to Seattle's clubhouse.
In return, the Twins should inquire about Logan Gilbert and see if there's a way to build a return package around him. Gilbert is under team control until 2027, which means Minnesota will have to send more than Polanco back, but Seattle would also be getting a guy with another year of team control so the gap isn't as large as it seems.
Seattle has a glut of young pitchers ready to make an impact, which makes Gilbert expendable even if he's a solid workhorse in the rotation. He might not be a 1-to-1 replacement for Sonny Gray, but could be an upgrade in the Kenta Maeda role and give the Twins a solid third starter behind Pablo Lopez and Joe Ryan.
