Cleveland Guardians call up pitcher Austin Peterson from Triple-A Columbus

The Cleveland Guardians promoted right-handed pitcher Austin Peterson to the major league roster on September 4, 2026. The move coincides with the team designating pitcher Carlos Hernandez for assignment. Peterson, a 26-year-old 2022 draft pick, transitions to the majors after posting a 4.27 FIP and a 9.6 strikeouts per nine innings rate with the Columbus Clippers. He utilizes a six-pitch repertoire, primarily featuring a slider, four-seam fastball, and sinker. The organization intends to evaluate his performance outside of the Triple-A environment, potentially utilizing him in a tandem role with Logan Allen. Coaching staff aim to leverage Peterson against right-handed hitters to balance the team's pitching matchups during the upcoming doubleheader.
