Rockies (3) @ Diamondbacks (5)

Arizona rookie Patrick Corbin pitched a gem on his last start of the season. He was in line for the loss, then the win, and finally earned a no-decision. John McDonald and Aaron Hill led the team to a walk-off victory over the Rockies.

Aaron Hill and John McDonald, both acquired for Kelly Johnson in 2011, each hit pivotal home runs to power the Diamondbacks over the Rockies at Chase Field.
