Aaron Bummer: Breaking News

Bummer retired the only batter he faced Monday to record his third hold of the season in a win over the Nationals. The southpaw got the final out of the seventh inning after Bryce Elder was lifted following 98 pitches, getting James Wood to ground out with Atlanta ahead 7-4. Bummer already has more holds than he did in either 2025 or 2024, and while his 4.76 ERA and 1.59 WHIP through 5.2 innings look shaky, he's been tagged with runs in only one of his nine appearances. He's become the newest incarnation of a LOOGY, working less than an inning in six of those outings while frequently being called in for the final out or two of an inning against left-handed hitters.

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.
