Phoenix, AZ – Justin Upton and Miguel Montero each homered 4 decision over the Colorado Rockies.
Gerardo Parra had four hits, scored three runs and drove in two, while Aaron Hill went 3-for-4 with an RBI for NL West-leading Arizona, which has won 11 in a row at home to tie a franchise record.
Wade Miley (2-1), in his third career start, scattered nine hits and two runs over six innings to earn the victory.
Aaron Cook (3-8) was tagged for six runs on seven hits in 4 1/3 innings for the Rockies, losers in four of their last five, including the first two in this three-game series.
Colorado got a solo home run from Dexter Fowler and three hits apiece from Carlos Gonzalez, Todd Helton, Kevin Kouzmanoff and Chris Iannetta.
Helton hit an RBI single in the first inning, but Arizona took the lead for good in the third when Parra tripled past Fowler in center to drive in two, then scored on an Upton groundout.
Iannetta brought Colorado within 3-2 on a run-scoring base hit in the fourth.
That was as close as the visitors got. With runners on the corners in the fifth, Montero found the seats in right for his 13th home run of the year.
Hill and Kouzmanoff traded RBI singles in the sixth and eighth innings, respectively, and Upton made it 9-3 in the latter frame with a two-run blast, his 26th longball of the year.
Fowler's first round-tripper of the season in the ninth accounted for the final margin.
