Perez (3-4) tossed six innings during Sunday's win against the Pirates, in which he allowed two runs on seven hits and a walk while striking out three.
The 25-year-old lefty allowed less than three runs for the fifth time in six starts during May, and has allowed only 10 runs in 36.1 frames over that span. Perez also registered a quality start for the fourth time in his last five starts, so he's on the right track so far. He will look to keep it going in his next outing against the Mariners on Saturday.
