DENVER — DJ LeMahieu hit a two-run homer off Yoshihisa Hirano in the ninth inning, and the NL West-leading Colorado Rockies rallied to beat the Arizona Diamondbacks 5-4 on Wednesday night.
LeMahieu hit a fastball over the fence in right as the Rockies kept their 1½-game advantage over Los Angeles intact after the Dodgers beat Cincinnati earlier in the day. The Diamondbacks fell 3½ games behind in the division race. This is the latest in the season the Rockies have been alone in first place since 1995.
Trying for a save on consecutive nights, Hirano (4-3) allowed a single by Gerardo Parra off the glove of first baseman Paul Goldschmidt to begin the ninth.
