PHILADELPHIA — Jose Bautista hit a grand slam and had a career-high seven runs batted in, and the Mets set a franchise record for runs while forcing the Phillies to use two position players for the final three innings of a 24-4 victory in the first game of a doubleheader Thursday.
Corey Oswalt (2-2) allowed four solo homers in six innings, Amed Rosario hit a leadoff homer and had three R.B.I., and the Mets took advantage of four errors to score 11 unearned runs. The Mets’ previous record was 23 runs against the Cubs in Chicago on Aug. 16, 2017.
Even reliever Jerry Blevins got his first career hit, a line-drive run-scoring single off infielder Scott Kingery.
“There’s nothing better,” Blevins said. “It’s something you dream about as a kid.”
The Mets have scored more than 15 runs in consecutive games for the first time in franchise history. They beat Baltimore, 16-5, on Wednesday night.
Rhys Hoskins, Maikel Franco, Nick Williams and Jorge Alfaro went deep for the Phillies.
