Corbin stays hot as D-backs top Padres, 4-2

Arizona shortstop Nick Ahmed hit a two-run homer in a four-run fourth inning and left-hander Patrick Corbin became the fourth four-game winner in the majors with the Diamondbacks' 4-2 victory over the San Diego Padres at Chase Field on Sunday. Ahmed's homer, his third of the season, made it 3-0 lead and Corbin's two-out single drove in the final run of the inning as the Diamondbacks (15-6) tied a franchise record for the best 21-game start to a season. Arizona is the first team since the 2003 San Francisco Giants to win its first seven series.
