PHOENIX, May 5 (UPI) -- Chris Iannetta put Colorado in front with a fourth-inning, two-run homer Wednesday and the Rockies halted a two-game skid by downing Arizona 6-4.
Colorado scored three times in both the fourth and fifth innings and then rode the starting pitching of Jhoulys Chacin (4-2).
Chacin, who had lost his previous two starts, gave up two runs on three hits and struck out six over seven innings. After Matt Reynolds gave up a ninth-inning homer to Juan Miranda and walked a batter, Huston Street came on to collect his 11th save.
Huston, however, gave up an RBI single and loaded the bases before getting Kelly Johnson to end the game by striking out.
Barry Enright hit a solo homer off Chacin in the third but Ian Stewart doubled home the tying run in the fourth and scored in front of Iannetta's fourth homer of the year.
Todd Helton then doubled in two runs in the fifth and scored on a base hit by Seth Smith to give the Rockies a 6-1 lead.
Barry Enright (1-3) took the loss, surrendering all six runs on six hits in five innings.
