Rockies 7, Diamondbacks 6: Todd Helton went 3-for-5 with three RBIs, including a run-scoring double to break a 6-6 tie in the eighth inning, as host Colorado rallied from a four-run deficit.

Carlos Gonzalez hit a one-out single in the eighth off Bryan Shaw (0-1) and advanced to third when Shaw's pick-off attempt sailed down the right-field line. After Shaw struck out Troy Tulowitzki, Helton delivered a line drive down the left-field line.

Rex Brothers (1-1) pitched a scoreless eighth and Rafael Betancourt worked around a one-out single by Miguel Montero in the ninth to earn his second save.

Ramon Hernandez went 2-for-4 with three RBIs, including his first homer in a Rockies uniform. Tulowitzki had three hits and scored twice.

Colorado's Juan Nicasio, making his first start at Coors Field since breaking his neck Aug. 5, allowed six runs and five hits in 2 2/3 innings. Nicasio also issued five walks after allowing 19 in his previous 14 career starts.

Three of the walks came after two were out in the first inning, and Paul Goldschmidt made him pay with a two-run single.

After solo home runs by Hernandez in the first and Dexter Fowler in the second made it 2-2, Arizona scored four times in the third, highlighted by Montero's two-run homer.
