Aaron Bummer - MLB News, Rumors, & Updates

Moving to big leagues The Royals selected Bummer's contract from Triple-A Omaha on Sunday.

Impact The left-hander joined Kansas City on a minor-league deal July 20 and will get a look in the majors after delivering four scoreless outings for Omaha. Bummer made 19 appearances for Atlanta earlier this year and surrendered 13 earned runs with a 13:10 K:BB over 15.1 innings.

Agrees to MiLB deal with Royals The Royals signed Bummer to a minor-league contract Monday, Jon Heyman of the New York Post reports.

Impact Bummer held a 7.63 ERA in 19 appearances for Atlanta earlier this season and has permitted four runs with a 6:2 K:BB over six innings during his time in the minors in 2026. The lefty reliever had a 26.9 percent strikeout rate in his first eight major-league seasons, but his strikeouts and velocity have both been down the last two years.

Opts out of minor-league contract Bummer opted out of his minor-league contract with the Cubs on Friday, Jon Heyman of the New York Post reports.

Impact After being released by Atlanta in May following a 7.63 ERA in 19 appearances, Bummer allowed four runs with a 3:2 K:BB over four innings with Triple-A Iowa. He now has the ability to negotiate with other teams, though it's possible he already has a deal in place somewhere.

Inks MiLB pact with Cubs The Cubs signed Bummer to a minor-league contract Wednesday, Bob Nightengale of USA Today reports.

Impact Bummer was released by Atlanta last week after collecting a 7.63 ERA and 1.83 WHIP across his first 19 relief appearances this season. The lefty's velocity has been tumbling in the wrong direction in recent years, but the Cubs will stick him at Triple-A Iowa and see if they're able to coax more out of the 10-year veteran.

Released by Atlanta Atlanta released Bummer on Tuesday.

Impact Bummer was torched for six runs on three hits and five walks over one inning of work in Monday's loss to the Marlins, pushing his ERA and WHIP on the season to 7.63 and 1.83, respectively. The veteran lefty's velocity has trended in the wrong direction in recent years, as the 90.2 mph he's averaging on his sinker is more than five mph lower than the 95.4 mph he averaged back in 2021. Bummer's track record should still be enough to land him a fresh start in a new organization.

Nabs third hold Bummer retired the only batter he faced Monday to record his third hold of the season in a win over the Nationals.

Impact 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.

Hangs onto bullpen spot Bummer will begin the season as part of Atlanta's bullpen, Chad Bishop of The Atlanta Journal-Constitution reports.

Impact 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.

Makes spring debut 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.

Impact 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.
