SAN FRANCISCO – Ryan Vogelsong gave the Giants every opportunity to win Wednesday night. However, when it was all said and done, he was not the one who got the official credit.

The right-hander was magnificent, throwing 6 2/3 innings of shutout ball at the Arizona Diamondbacks while giving up only two hits, striking out three and overcoming a season-high five walks as the Giants scooted away with a 5-0 win at AT&T Park.

The win – the eighth straight home win and the longest such streak since winning nine straight in 2011 – allowed the Giants to stay within 2½ games of the Los Angeles Dodgers in the National League West race while remaining on top of the NL’s wild-card standings with a four-game advantage over the Pittsburgh Pirates.

Vogelsong had a lot to do with that Wednesday night.

The problem was that, although they made a number of very nice defensive plays behind him, his teammates did absolutely nothing for him on offense – a theme that has been disturbingly common in Vogelsong starts – while he was in the game.

To be exact, Wednesday marked the seventh time in 15 home starts this season that he has not gotten a single run of support.

Sadly enough, even though he did almost all the work, someone else ended up getting the “W” attached to his record.

Vogelsong was taken out with two outs in the top of the seventh, and Jean Machi retired Jordan Pacheco to end the inning and preserve the scoreless tie.

“He pitched a great game, which is what we needed,” manager Bruce Bochy said. “He was getting a little out of sync (in the seventh), so we figured we get someone going, in case something happened.”

The Giants were up against a tough out in starter Josh Collmenter, who entered Wednesday’s game with a 3.81 ERA. Collmenter tossed six scoreless innings and surrendered only three hits while striking out three and walking two.

In the bottom of the inning, the Giants finally strung some hits together to break the deadlock, as soon as they were able to get into Arizona’s bullpen.

Hunter Pence led off the inning by getting a walk off reliever Oliver Perez before the next batter, Gregor Blanco, who has really found a home for himself in the sixth spot in the lineup, smoked one down the right-field line off Perez.

When right fielder Alfredo Marte could not initially handle the ball cleanly after tracking it down, Pence was able to motor home from first to put the Giants ahead.

They weren’t done, however. After Brandon Crawford legged out an infield single, pinch hitter Matt Duffy smacked one the other way past Marte, bringing in Blanco. Crawford soon scored on a wild pitch while Duffy would scamper home on a sac fly to give the Giants a suddenly-commanding 4-0 lead.

The Giants tacked on another run in the eighth, when Travis Ishikawa singled in Pablo Sandoval, who had doubled with one out and moved to third on an infield single by Pence.

NOTES: The Giants surpassed the three-million-fan attendance mark for the 2014 season Wednesday night, marking the fifth straight year that the club has drawn more than 3,000,000 fans to AT&T Park.
