Starling Marte hit a go-ahead, three-run home run in the sixth and first baseman Pete Alonso made a spectacular rally-killing play in the bottom of the inning for the New York Mets, who beat the struggling Los Angeles Dodgers 6-4 Saturday to extend their winning streak to six games. The Mets won their fifth straight series and have gone 12-3 after an 0-5 start. The Dodgers' struggles at the plate continued as they lost for the seventh time in nine games.
