Overview
- Multiple outlets reported Monday that Aaron Bummer agreed to a minor‑league contract with the Kansas City Royals and has been assigned to Triple‑A Omaha.
- The signing follows a sequence this season in which Atlanta released Bummer in mid‑May, the Cubs signed him to a minor‑league deal on June 1 and he exercised an opt‑out in July.
- Bummer has shown clear recent decline, posting roughly a 7.6 ERA in 19 appearances in 2026, a drop in strikeout rate to about 16.9%, and a falling four‑seam velocity near 90.5 mph.
- Kansas City has thin pitching depth because of multiple injuries to starters and relievers and has a bullpen ERA near the bottom of MLB, which creates a real chance for a Triple‑A rebound to earn a big‑league look.
- The move is financially low risk for the Royals because Atlanta remains responsible for most of Bummer’s reported 2026 salary so any promotion would cost Kansas City only the prorated league minimum.
