Mason Montgomery

Pittsburgh Pirates left-hander Mason Montgomery has arguably been his team's top relief option this season, recording a 2.73 ERA, 1.02 WHIP, 95 strikeouts, 13 saves, and six wins across 62 2/3 innings (64 games). The hard-throwing southpaw is averaging 98.5 miles per hour on his fastball and has posted a ridiculous 37.5% strikeout rate while limiting his walk rate to a manageable 9.1%. While the Pirates deployed Montgomery in a high-leverage setup role for much of the season, he's taken over as the team's undisputed closer recently. Montgomery has already recorded six saves in September, and he has not allowed an earned run since late July. Heading into the final few weeks of the 2026 season, fantasy managers should view Montgomery as an elite closer option.
