Madison Bumgarner pitched through rain to extend his Citi Field scoreless streak to 18 innings, Hunter Pence homered and drove in three runs, and the San Francisco Giants ran at will against Noah Syndergaard in a 6-1 victory Sunday that stopped the New York Mets' eight-game winning streak. After Yoenis Cespedes' third-inning double put runners at second and third, Bumgarner retired Neil Walker on an inning-ending popup. One start after allowing five steals against Cincinnati, Syndergaard (2-1) gave up three more, and the stolen bases got him into trouble.
