PHOENIX, April 8 (UPI) -- San Francisco's Brandon Crawford and Buster Posey each committed seventh-inning errors Sunday, allowing Arizona to rally for a 7-6 victory.

Trailing 6-0 early, the Diamondbacks battled back to pull within a run entering the seventh.

After Santiago Casilla issued a pair of walks to load the bases with one out, Willie Bloomquist came home with the equalizer on shortstop Crawford's fielding error, sending Aaron Hill to third.

Sergio Romo came in to pitch, and Chris Young hit a bouncer to third baseman Pablo Sandoval. His throw home pulled Posey off the plate, but the catcher was given an error -- his second of the game -- as Hill scored the go-ahead run.

Ryan Roberts smacked a two-run homer and Lyle Overbay added a solo shot in the sixth inning for the D-Backs, who completed a three-game, season-opening sweep of the Giants.

Wade Miley (1-0) earned the victory with four innings of shutout relief and Bryan Shaw tossed a scoreless ninth for his first save.

Jeremy Affeldt (0-1) was tagged with the loss for the Giants, who got a two-run homer from Posey.
