Seattle Mariners Announce ALCS Roster

The Seattle Mariners have announced their roster for the best-of-seven ALCS, featuring 13 pitchers and 13 position players.

As reported by Shannon Drayer, Mariners Insider at Seattle Sports, the team made two changes to their roster ahead of their ALCS Game 1 matchup against the Blue Jays in Toronto.

The roster includes 2025 All-Star starting pitcher Bryan Woo, who has been added after recovering from pectoral tightness. Woo threw a bullpen session on Friday in Seattle to determine his readiness.

According to the team, Woo is not expected to pitch early in the series and will likely be on a limited pitch count when he makes an appearance.

The Mariners have elected to go with 13 pitchers and 13 position players for the ALCS.
