Pittsburgh, PA (Best E Casino) - Chris Snyder led off then ninth inning with the go-ahead homer, as the Arizona Diamondbacks edged the Pittsburgh Pirates, 4-3, in the second installment of a four-game series at PNC Park.

Dan Haren pitched well through seven innings, surrendering three runs on five hits and a walk. He struck out six. Juan Cruz (2-0) tossed a perfect eighth for the win and Brandon Lyon earned his 14th save of the season for Arizona, which won its second straight after losses in eight of 10.

"It's a really nice team win," Haren said. "To get back to where we want to be, where we were winning the division, getting into the playoffs. These are games that over the last 4 to 5 weeks, we haven't been winning."

Chris Young had two doubles and a run batted in, while Mark Reynolds and Conor Jackson added an RBI each for the D'Backs.

Tom Gorzelanny settled down after a rocky start, allowing three runs, all in the first, on five hits and three walks over seven innings. John Grabow (4-2) pitched two innings, allowing Snyder's home run, in taking the loss for Pittsburgh. Jason Bay and Nate McLouth both homered in the loss.

"You know with Haren going you're not going to get a ton of runs," Bay said. "We kind of battled back and achieved a chance at the "w"(win). We had a chance to take the lead, and that's the way we've been playing. Even against good pitching our offense is not sticking a dozen off them, but we're getting enough (runs). That's something that we haven't done before."

Snyder connected on a line-drive home run to left, and in the bottom half, Lyon allowed a leadoff single to Ryan Doumit. Luis Rivas came in to pinch-run. After Jason Michaels flied out, Snyder gunned down Rivas trying to steal for the second out. Doug Mientkiewicz worked a walk, but Adam LaRoche hit a weak fly ball to left, ending the game.

Gorzelanny had a rough first inning, walking two of the first three batters before giving up a Jackson RBI single followed by an RBI double to left from Young. Reynolds then lofted a sacrifice fly to right, staking Haren to an early 3-0 lead.

The Pirates got one back in the third. LaRoche walked to start the inning, moved to second on a sacrifice bunt and scored on a line-double to right from McLouth.

Bay got another one back for the Bucs in the fourth, lifting a leadoff homer just over the wall in right-center.

The Pirates completed the comeback in the fifth, tying the score on McLouth's 14th home run of the season to the right field seats.
