Perez won't start as scheduled Thursday against the White Sox since the game was postponed due to rain.
Perez should instead take the mound this weekend against the Mets. The southpaw has posted a 3.45 ERA and 1.21 WHIP with nine strikeouts over 15.2 frames in his last three outings, and he owns a 4-0 record and 3.09 ERA over 43.2 career innings against the Mets.
