Phoenix, AZ (Sports Network) - Ray Durham homered and drove in four runs as the San Francisco Giants pounded the Arizona Diamondbacks 11-3 in the middle installment of a three-game series.

It was the biggest output of the season for the Giants, who received three-hit efforts from Jose Castillo and Bengie Molina. Molina also knocked in two runs and is hitting .590 (23-for-39) with 16 RBI during a current 10-game hitting streak.

Aaron Rowand and Emmanuel Burriss each drove in a pair in San Francisco's second straight triumph.

Jonathan Sanchez (3-3) was credited with the victory, allowing two runs on six hits and three walks while fanning six in a six-inning start.

"The offense scored a lot of runs and that was the key of the game," Sanchez said. "With a lot of runs behind me I can go out there and not worry. I was getting ahead of guys, my fastball was working, my sinker."

Doug Davis (2-2) was roughed up for six runs on nine hits and three walks, as Mark Reynolds' solo home run and Justin Upton's two-run double provided the offense for Arizona, which has dropped three straight affairs.

"I didn't have great command where I could get ahead," Davis said. "When I was pitching behind in the count that is pretty much when I got hurt and walks don't help either."

Durham got things started with a one-out, solo shot to left in the top of the second, and two innings later Rowand made it a two-run game with a run-scoring single to right.

Back-to-back four-run frames in the fifth and sixth inning blew the game open.

Rowand produced another RBI single in the fourth and Aurilia worked a bases loaded walk two batters later before Burriss brought home a pair with a single to left.

Davis finally got the hook, but the Giants put their foot on the gas in the sixth. Molina kept his torrid stretch going in with an RBI double before reliever Doug Slaten hit Rowand to load the bases. Durham cleared them a batter later with a shot to center, putting the visitors ahead by an insurmountable 10 runs.

Upton cracked the scoreboard for Arizona with a two-run double in the bottom of the sixth, while Molina plated the Giants' final run with a single a frame later.

Reynolds' two-out, no-doubter to left field in the eighth did little to soil San Fran's impressive drubbing.
