Peralta (10-8) allowed three runs on seven hits and two walks over 4.2 innings Sunday, striking out four and taking a loss against Colorado.
Peralta coughed up a home run to Hunter Goodman in the third inning and was charged with two more runs when Sam Hilliard took Hoby Milner deep for a three-run blast in the fifth. It was Peralta's first loss since Aug. 12; he entered Sunday's start with a 1.61 ERA and a 3-0 record over his previous four starts. Peralta still generated an impressive 18 swinging strikes despite his lackluster outing. He'll carry a 3.81 ERA into his next matchup, which is lined up to be in Arizona.
