Atlanta re-signed Perez to a minor-league contract Wednesday, Jon Heyman of the New York Post reports.
Perez elected free agency after clearing waivers following his removal from Atlanta's 40-man roster, but he's quickly re-upped on a minor-league pact. The veteran left-hander held a 3.14 ERA, 0.91 WHIP and 6:4 K:BB across 14.1 innings during his time with the big club and could re-enter the major-league rotation as soon as next week.
