Phoenix, AZ (SportsNetwork.com) - Troy Tulowitzki smacked a solo homer, a pair of doubles and drove in three as the Colorado Rockies defeated the Arizona Diamondbacks, 8-5, in the opener of a three-game set.

Franklin Morales (3-1) allowed four runs on seven hits and two walks over five innings to notch the win. LaTroy Hawkins fired a scoreless ninth for his eighth save of the year.

Wade Miley (2-3) was roughed up for seven runs on 10 hits and a walk over six frames for Arizona, which has dropped three straight on the heels of a three- game winning streak.
"I didn't get the job done," Miley admitted. "That one's on me."
