The Colorado Rockies continue to be dominated by the Arizona Diamondbacks. They lost for the seventh time in the last eight meetings against the NL West leaders, falling 9-4 last night in Phoenix. The Rockies took a 1-0 lead in the first inning on a Todd Helton RBI single, but Aaron Cook couldn’t make that stand up as he allowed six runs on seven hits in four and two-thirds innings to take the loss. The Rockies managed 13 hits, just one fewer than the D-Backs, but failed to turn them into runs. Dexter Fowler provided a late highlight for the Rockies by hitting his first home run of the season, a solo blast in the ninth. The Rockies will try and avoid a series sweep in tonight’s finale. Esmil Rogers will take the mound for Colorado, opposing Arizona’s Josh Collmenter. First pitch is set for 8:40.
