Mark Reynolds hit a three-run homer, Conor Jackson and Chad Tracy also connected and the Arizona Diamondbacks gave Dan Haren plenty of early offense in a 10-2 victory over the San Francisco Giants on Friday night.

Stephen Drew and Chris Young hit two-run doubles in Arizona's five-run second inning, when the D-backs batted around against Jonathan Sanchez (8-6) on four hits, three of them doubles. Chris Snyder singled in the other run that inning and Jackson had a double.

Haren (10-5) matched his season high with nine strikeouts and didn't walk a batter in eight innings to win consecutive starts for the first time this month. He allowed nine hits and two runs.

First-place Arizona quickly showed why it is atop the NL West despite the division's poor record this year, ending the Giants' momentum after San Francisco took three from the Washington Nationals for the club's first home sweep of the season.

Both clubs considered this a key series _ and the Diamondbacks began a stretch of 10 straight division road games in impressive fashion.

With Arizona leading 6-1, Reynolds hit the first pitch from rookie Geno Espineli over the wall in center for his 20th homer. Tracy followed with his sixth homer to chase Espineli, who earned his first major league win Wednesday in his second career outing.

Arizona hit consecutive home runs for the second time this year. Justin Upton and Reynolds did it on May 31 at Washington.

Jose Castillo singled in the Giants' first run in the fifth and Fred Lewis added an RBI single in the seventh. Continued...
