Atlanta signed Perez (shoulder) to a minor-league contract Friday, Aram Leighton of JustBaseball.com reports.
Elbow and shoulder woes limited Perez to just 56 innings in 2025 with the White Sox, but he pitched well when on the bump, collecting a 3.54 ERA, 1.11 WHIP and 44:22 K:BB. It's unclear whether the shoulder strain that ended his season will affect his readiness for the start of spring training. There isn't room for Perez in Atlanta's rotation when everyone is healthy, but Spencer Schwellenbach (elbow), Grant Holmes (elbow) and Reynaldo Lopez (shoulder) all ended the 2025 campaign on IL.
