Peralta (5-6) took the loss against the Phillies on Saturday, allowing 10 runs on 10 hits and one walk with two strikeouts over 2.2 innings.
Peralta was down 3-0 when he began a nightmare third frame in which he was charged with seven more runs. The 30-year-old yielded a career-high 10 earned runs overall in his shortest outing of the campaign, with his ERA rising from 3.90 to 4.83 for the season. He's now been charged with four earned runs or more in four of his past six starts. Peralta will take that inflated ERA, a 1.39 WHIP and 83:34 K:BB across 85.2 innings into a home matchup against the Cubs next week.
