Abraham Toro took over at second base for the Mariners at the trade deadline, but there could be better options in free agency.
Ben: Marcus Semien had one of the all-time great seasons for a second baseman in 2021. The Mariners are desperate for infield/offensive help, and Semien is the perfect fit. He is a West Coast guy, and Dallas Braden had hinted on his show “Starting 9” that Semien would prefer to return to the West Coast. It will take a high dollar amount to land him, but for a team this thin in the infield, it is a necessity. If he is their one big money signing, Semien is a no-brainer to plug in with JP Crawford in the middle.
Connor: Arguably the best free agent on the market this offseason is Toronto Blue Jays second baseman Marcus Semien, and I believe he would be a perfect fit on the Mariners. A .265/.334/.538 slash line, 45 home runs, 102 RBIs, 15 stolen bases, and a .985 fielding percentage at second base tell the whole story for Semien; he’s a player that can hit anywhere between in the top four of the batting order, can help produce runs with his speed, and can give you solid defense.
Derek: This is the position where I would really like to see the Mariners go out and give a guy like Marcus Semien a blank check. Second base production has been atrocious since Robinson Cano was shipped out, and while they have the guys with the athleticism to play the position defensively, no one has been able to produce consistently at the plate. My plan calls for them to go all in and get a guy that can fill that hole in the roster.
Max: One of the top free agents available, Marcus Semien is a premier talent that can seriously augment Seattle’s hopes of contention. Semien was one of the most valuable players in all of baseball last season for Toronto, and fills a position of need for the Mariners. With all the payroll flexibility in the world, Semien needs to be the starting second baseman for the Seattle Mariners in 2022.
