Cody Ross drove in the game-winning run with a sacrifice fly in the 10th inning as the Arizona Diamondbacks edged the Colorado Rockies, 3-2.
With runners on the corners, Ross lifted a fly ball deep to the warning track in left-center field, scoring A.J. Pollock without a throw. Pollock stole second earlier in the inning.
"Just picked out the right pitch and the right count and just trust it," Pollock said of the steal.
Ross also had an RBI triple. Pollock went 3-for-5 with a homer and scored twice for the Diamondbacks, winners in four of their last five.
J.J. Putz (2-0) earned the win after tossing a perfect 10th. Starter Wade Miley threw 4 1/3 scoreless innings. He ran into trouble in the fifth after walking a pair and giving up a single to load the bases.
Wilin Rosario went 3-for-4 with a homer and Troy Tulowitzki had two hits and an RBI for the Rockies, losers in five of their last seven.
"It was a very strange game," Colorado manager Walt Weiss said. "When you miss that many opportunities, it's going to come back to haunt you."
Edgmer Escalona (1-1) was charged with the loss after giving up the winning run. Starter Jeff Francis gave up two runs on four hits over five innings.
The Diamondbacks scored a pair of runs in the first inning. Pollock clubbed a one-out homer. Miguel Montero followed with a single two batters later then scored when Ross ripped a triple to right field.
Rosario hit a leadoff homer in the sixth inning to pull the Rockies within 2-1.
Colorado added another run in the seventh to tie the game. Dexter Fowler doubled then moved to third on a Jordan Pacheco ground out. After Carlos Gonzalez popped out, Tulowitzki laced a base hit to center to push Fowler across.
