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 Ms will use an even 13 pitchers and 13 position players to navigate their series with Toronto. The full list Catchers: , , Infielders: , , , , Outfielders: , , , Utility player: Left-handed pitchers: , Right-handed pitchers: , , , , , , , , , , The biggest story is Woos return, as the right-hander hasnt pitched since suffering pectoral tightne s in a start against the Astros on September 19. Woos ramp-up work didnt quite allow him to Brandon Pfaadt Jersey be ready for Seattles ALDS roster, but president of baseball operations Jerry Dipoto after the Mariners Game 5 clinch that Woo would likely be part of the roster against Toronto. Dipoto specified that Woo wouldnt 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 a sumed 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 , who didnt see any action in the ALDS (and hasnt played in a big league game since July 30). Williamsons inclusion on the ALDS roster was largely as a hedge against potentially mi sing time on paternity leave, so the Mariners wouldnt 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. Seattles other change comes on the bench, with one left-handed utilityman in Mastrobuoni replacing another in . Mastrobuoni doesnt have Raleys 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. E sentially, Mastrobuonis 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. Jorge Barrosa Jersey
