DENVER -- Cristian Adames hit a two-run double in the ninth inning off veteran Joe Nathan to rally the Colorado Rockies past the San Francisco Giants 6-5 on Wednesday night.
Nolan Arenado homered to start the three-run rally, and Tom Murphy and David Dahl also went deep for the Rockies.
With Colorado trailing 5-3, Arenado led off the ninth with his NL-leading 37th home run off Santiago Casilla. After Murphy's one-out single, Jake Osich (1-1) entered and hit pinch-hitter Charlie Blackmon. Nick Hundley's bloop single off Nathan loaded the bases, and Adames lined a double off the wall in right to end it.
Jordan Lyles (4-4) pitched the ninth to get the win.
The Giants hold the first NL wild-card spot by a half game over the St. Louis Cardinals and New York Mets. They are 17-32 since the All-Star break.
The Giants built an early lead on homers by Brandon Belt and Gorkys Hernandez, who had two hits each.
Hernandez, who turned 29 on Wednesday, doubled ahead of Belt's two-run homer in the second and led off the fourth with his first home run since Oct. 2, 2012, with Miami, to make it 4-1.
The Rockies crept back into the game with consecutive home runs by Dahl and Murphy in the fourth. Hunter Pence made it a two-run game in the fifth with a double, one of his three hits.
