Phoenix, AZ (My Sportsbook) - Dan Hudson pitched seven solid innings and Stephen Drew fueled Arizona's offense, as the Diamondbacks took a 3-1 win over the San Francisco Giants to avoid being swept in the three-game series.

Hudson (5-1) gave up one run on five hits and two walks to get another win against the Giants. He took the victory back on August 28 after limiting San Francisco to two runs in seven innings.

"My changeup was good tonight. It was actually a little bit slower than normal. It had a little more depth," Hudson said. "I think I was able to get some guys out in front on that and able to get in on their hands a little bit right after that."

Drew tripled and scored the decisive run in the third inning on Kelly Johnson's single. Drew added an RBI single in the seventh for Arizona, which snapped a four-game losing streak.

Barry Zito (8-12) limited Arizona to two runs in six innings, and struck out seven. But he still took the loss for a fifth straight start as the Giants had their four-game win streak broken.

San Francisco fell to two games behind San Diego in the NL West, as the Padres beat Los Angeles on Wednesday. The Giants begin a four-game series in San Diego on Thursday.

"You have two teams trying to get there. They're playing well right now. They've had a good year," said Giants manager Bruce Bochy. "So it should be an exciting series. It's what you play for in September. Work hard in the spring, and you get to this point, this is what it's about."

The Giants also dropped two games behind Atlanta in the wild card chase following the Braves' win over Pittsburgh.

With one out in the first inning, Freddy Sanchez homered to left to put the Giants in front. However, some inaccuracy from Zito helped Arizona tie the game in the second.

Zito walked Chris Young and Adam LaRoche to begin the second, and after Mark Reynolds grounded into a double play, Miguel Montero doubled to center to plate a run.

Johnson's third-inning hit put the Diamondbacks up, 2-1, and Hudson made the lead hold up. He got a double-play grounder to end the fourth, then set San Francisco down in order in the fifth and sixth.

The Giants then had runners at the corners with two away in the seventh. But Hudson retired Travis Ishikawa, pinch-hitting for Zito, to ground out to first.

After Drew's RBI single gave the Diamondbacks a two-run edge, Esmerling Vasquez worked a scoreless eighth. Juan Gutierrez worked around a leadoff double by Jose Guillen in the ninth to seal the victory.

Game Notes

Gutierrez got his eighth save...Zito has dropped his last eight decisions. He hasn't gotten a win since July 16, though has five quality starts since then.
