Peralta will start in Saturday's game against the Dodgers.
It will be the fourth time this season that Peralta serves as the Padres' opener, and he will likely toss one or two innings before handing the keys to Griffin Canning. Peralta gave up four runs on six hits while striking out two in one inning against the Dodgers on Thursday, but in his 37 appearances prior to that, he had a 1.62 ERA, 1.22 WHIP, three holds and a 28:18 K:BB across 44.1 innings.
