The Mariners announced the 26 players who will be part of their American League Championship Series roster against the Blue Jays. After using a complement of 14 pitchers and 12 position players against the Tigers in the ALDS, the M’s will use an even 13 pitchers and 13 position players to navigate their series with Toronto. The full list…
Catchers: Harry Ford, Mitch Garver, Cal Raleigh
Infielders: J.P. Crawford, Josh Naylor, Jorge Polanco, Leo Rivas, Eugenio Suarez
Outfielders: Randy Arozarena, Dominic Canzone, Victor Robles, Julio Rodriguez
Utility player: Miles Mastrobuoni
Left-handed pitchers: Caleb Ferguson, Gabe Speier
Right-handed pitchers: Eduard Bazardo, Matt Brash, Luis Castillo, Logan Gilbert, Emerson Hancock, Luke Jackson, George Kirby, Bryce Miller, Andres Munoz, Carlos Vargas, Bryan Woo
The biggest story is Woo’s return, as the right-hander hasn’t pitched since suffering pectoral tightness in a start against the Astros on September 19. Woo’s ramp-up work didn’t quite allow him to be ready for Seattle’s ALDS roster, but president of baseball operations Jerry Dipoto said on Friday after the Mariners’ Game 5 clinch that Woo would likely be part of the roster against Toronto.
Dipoto specified that Woo wouldn’t be available until closer to midway through the series, which would seemingly line him up for a start in Game 4. Because Gilbert and Castillo were both needed in the 15-inning finale against Detroit, the Mariners’ rotation plans over the first two ALCS games in Toronto are very much up in the air. Miller will start Game 1 on short rest and it can be assumed that Kirby will start Game 3 on regular rest, but it remains to be seen if Castillo and/or Gilbert will be involved in Game 2, and in what capacity.
Woo takes the roster spot of rookie infielder Ben Williamson, who didn’t see any action in the ALDS (and hasn’t played in a big league game since July 30). Williamson’s inclusion on the ALDS roster was largely as a hedge against Josh Naylor potentially missing time on paternity leave, so the Mariners wouldn’t be left short-handed in terms of infield depth. As it happened, Naylor played in all five games against Detroit and was still able to welcome his first child into the world.
Seattle’s other change comes on the bench, with one left-handed utilityman in Mastrobuoni replacing another in Luke Raley. Mastrobuoni doesn’t have Raley’s offensive upside, but brings more to the table in pure versatility. Raley can play first base and all three outfield positions, but Mastrobuoni saw work at both corner outfield slots and at first base in 2025, as well as time as a second and third baseman. Essentially, Mastrobuoni’s inclusion allows the Mariners to replace Raley and Williamson in one fell swoop. Raley came off the bench in four games of the ALDS, with one hit-by-pitch over six plate appearances.
