Cleveland Guardians call up pitcher Austin Peterson for major league debut

Summary

The Cleveland Guardians promoted right-handed pitcher Austin Peterson from Triple-A Columbus on Friday. The 6-foot-6, 234-pound pitcher joins the major league roster, with the team planning to use him primarily out of the bullpen. This move coincided with the activation of Slade Cecconi from the 15-day injured list. Simultaneously, the organization placed Colin Holderman on the 15-day injured list and designated Carlos Hernandez for assignment. Peterson, a ninth-round draft choice in 2022, has maintained a 4.53 ERA across 21 appearances at the Triple-A level this season. If he appears in a game, it will mark his first appearance in the major leagues.
