Gibson (10-6) allowed eight runs on eight hits and two walks over 5.1 innings Friday, striking out four and taking a loss against Miami.
Through five frames, the only damage against Gibson was a three-run homer by Jesus Sanchez in the first inning. The Marlins then erupted for seven runs in the sixth, with five of those being charged to the 33-year-old. Gibson's ERA jumped from 2.94 to 3.30 through 155.1 innings this season. It was just the second time in his seven starts with the Phillies that he allowed more than three runs. Gibson is lined up to face the Brewers on the road next week.
