Chase Utley hit a leadoff homer and added a tiebreaking RBI double in the eighth inning, and the Los Angeles Dodgers snapped their four-game losing streak with a 4-1 victory over the Arizona Diamondbacks on Wednesday night. Utley's double to the wall in right field drove in Jimmy Rollins, whose bunt single leading off the eighth was Los Angeles' first hit since Utley's homer on Chase Anderson's first pitch. Corey Seager then added a two-run homer for the Dodgers (86-65), who lowered their magic number for clinching a playoff berth and their third straight NL West title to six.
