Paul Skenes allowed one run over six solid innings but the San Francisco Giants rallied against the Pittsburgh Pirates' bullpen for a 7-6 win Thursday. Matt Chapman hit a three-run homer off Hunter Stratton (1-1) in the eighth and Brett Wisely delivered a go-ahead single off Aroldis Chapman five batters later as the Giants overcame a big deficit for the second time in less than 24 hours. San Francisco trailed by five early in a 9-5 extra-inning victory on Wednesday.
