The Rockies won for the fourth time in five games, taking two of three in the series. The Reds have lost 10 of 11, a streak that started when one of the home run smokestacks at Great American Ball Park caught fire during a loss to the Giants on May 15.
Arenado hit his 10th homer in the first inning off Mike Leake (2-4) and added a single. In the past four games, the third baseman is 9 for 16 with three homers, one triple and 10 RBIs.
