SAN FRANCISCO-When will the San Francisco Giants win a game at the usual friendly confines of AT&T Park.

Ruby De La Rosa went eight strong innings, as the Arizona Diamondbacks completed their first three-game sweep at AT&T Park since July 25-27, 2008 with a 4-0 victory over the Giants before a crowd of 41,310, the 360th consecutive sellout.

De La Rosa allowed four hits, while walking two and striking out six on his way to his fifth win of the season.

Just five days after throwing his first career no-hitter, Chris Heston lasted only five innings, as he allowed three runs on seven hits, walking four and striking out six.

Brandon Crawford committed two errors on the same ball hit by Wellington Castillo in the top of the second inning that allowed Jake Lamb to score from second base.

Chris Owings hit a two-run double to straightway centerfield in the top of the fifth inning that scored Ender Inciarte and Paul Goldschmidt.

A.J. Pollock drove in the fourth and final run of the game with a sacrifice fly to centerfield that scored Inciarte.

The Giants began to threaten in the bottom of the ninth, as Joe Panik doubled and then Brandon
Belt, but then Brandon Crawford struck out and then Casey McGehee walked to load the bases for pinch-hitter Buster Posey, who batted for Justin Maxwell.

Posey ended the game, as he grounded into a double play.
