Aaron Bummer: Breaking News

Bummer will begin the season as part of Atlanta's bullpen, Chad Bishop of The Atlanta Journal-Constitution reports. The 32-year-old southpaw will likely slot in behind Dylan Lee in the pecking order for high-leverage work. Bummer has been a fairly reliable middle-relief option for Atlanta over the last two seasons, posting a 3.69 ERA, 1.34 WHIP and 120:35 K:BB in 109.2 innings, but in 98 appearances he has just seven wins, four holds and zero saves.

Bummer (shoulder) struck out a batter in a perfect inning of relief in Friday's 15-8 win over the Red Sox in Grapefruit League play. Bummer is back to full health after spending the final five weeks of the 2025 season on the shelf due to left shoulder inflammation. The 32-year-old is set to serve as one of Atlanta's top left-handed options out of the bullpen in 2026 after compiling a 3.81 ERA, 1.25 WHIP and 51:17 K:BB across 54.1 innings last season.

Atlanta transferred Bummer (shoulder) to the 60-day injured list Thursday. Left shoulder inflammation sent Bummer to the injured list in late August, and although he began a throwing program Saturday, his move to the 60-day IL will officially rule him out for the rest of the season. He'll give up his place on the 40-man roster to Brett Wisely, who was claimed off waivers from San Francisco in a corresponding move.
