Rockies 7, Diamondbacks 6: Wilin Rosario belted a two-run homer in the bottom of the ninth inning - his fourth hit of the game - as Colorado erased a five-run deficit with a walk-off victory.

Corey Dickerson led off the ninth with a pinch-hit single against Addison Reed (1-7) and, after Justin Morneau and Michael Cuddyer flew out, Rosario crushed the first pitch he saw on to the concourse in left for his first walk-off homer. LaTroy Hawkins (4-3) pitched a perfect ninth to earn the victory.

Cuddyer homered among his three hits and scored three runs, while Brandon Barnes, Charlie Culberson and DJ LeMahieu also recorded RBIs for the Rockies. Rookie Ender Inciarte and Jordan Pacheco drove in two runs apiece, while Aaron Hill and Cody Ross each contributed RBIs for Arizona.

Arizona broke open a 2-1 game with four runs in the sixth, starting with Hill's bases-loaded walk against Tommy Kahnle. Ross greeted Matt Belisle with a sacrifice fly that also advanced the other runners and, after Miguel Montero was intentionally walked, Pacheco - a former Rockie - delivered a two-run single.

Colorado began to chip away in the bottom half as Barnes' double to right drove in Cuddyer and Culberson followed with an RBI single. The Rockies added two more in the eighth on Rosario's single and LeMahieu's double before Will Harris retired Josh Rutledge with two aboard to end the inning and preserve the lead.
