Rookie Miguel Vargas drove in the go-ahead run with an infield single in a five-run eighth inning and the Los Angeles Dodgers rallied past the Arizona Diamondbacks 6-5 Tuesday for their MLB-leading 44th comeback win in the first game of a doubleheader. The Dodgers, with the best record in the majors, won their fifth in a row. Los Angeles shortstop Trea Turner exited in the fifth after being hit in the side by a ball that ricocheted off a runner's helmet.
