Perez (0-2) allowed five runs on five hits and two walks while striking out two over 5.2 innings to take the loss Friday at the White Sox.
Perez allowed two runs in the first five innings to keep the game close, but he fell apart in the sixth inning when he was chased after allowing three more runs. Until this start, he had recorded quality starts in each of his three other outings, but his rough outing moved his ERA up to 4.50. He'll look to get back on track in his next start Wednesday against the Yankees.
