Seattle Mariners promote prospect Lázaro Montes to major league roster
Summary

The Seattle Mariners are promoting outfield prospect Lázaro Montes to the major league roster. The move coincides with the expansion of active rosters to 28 players this Tuesday. Montes, who ranks as the organization's No. 5 prospect, has spent the 2026 season between Double-A and Triple-A, hitting 38 home runs with 96 RBI. While primarily an outfielder, the 21-year-old has drawn scouting projections as a future designated hitter due to his power at the plate. The Mariners currently trail the final American League Wild Card spot by five games. The team plans to evaluate the power hitter's performance as they look to maintain their postseason contention through the final month of the regular season.
