Tyler Colvin also homered and doubled to drive in three runs to help the Rockies cool off the Padres, who had won 10 of their previous 11.
Chacin (2-4) allowed one run on five hits for his second win since coming back Aug. 21 after spending more than three months on the DL because of inflammation in his pitching (right) shoulder.
It was the first time a Rockies starting pitcher had gone seven innings since the team instituted its unorthodox four-man rotation with a roughly 75-pitch limit per outing June 19 (Chacin had 74 pitches). The last starter to go that long in a game was Jeremy Guthrie on May 31 against Houston.
