Atlanta Braves reliever Aaron Bummer reached 400 career games pitched on April 28, 2026, becoming the latest pitcher to achieve this milestone in his 10th major league season.
Bummer's path to 400 games began with his 2017 debut with the Chicago White Sox, where he spent seven seasons before joining the Atlanta Braves in 2024. His most active season came in 2021 when he appeared in 62 games for Chicago, followed by 61 games in 2023. After appearing in 56 games during his first season with Atlanta in 2024, Bummer has continued his steady presence in the Braves bullpen with 42 appearances in 2025.
The milestone represents sustained durability for the left-handed reliever, who has maintained consistent availability throughout his career despite some injury-shortened campaigns. His 2020 season was limited to just 9 games, while 2022 saw him appear in 32 contests.
Bummer approaches his next career milestone with 436 strikeouts remaining before reaching 500 career strikeouts, a threshold that remains within reach as he continues his role in Atlanta's bullpen.
