CHICAGO (Ticker) -- Raul Mondesi can finally relax after helping his new team end its longest road drought.

Mondesi doubled in Luis Gonzalez with the go-ahead run after rookie Alex Cintron belted a game-tying homer in the ninth the Diamondbacks posted a 4-3 victory over the Chicago Cubs .

Trailing 3-2, the Diamondbacks were able to snap a franchise-record 10-game road losing streak by rallying in the ninth against Cubs closer Joe Borowski (1-2).

Cintron started the uprising by leading off with his ninth homer of the season. Gonzalez followed with an infield hit before Borowski retired Shea Hillenbrand .

Acquired from the New York Yankees on Tuesday, Mondesi came through with an RBI double into the left-center field gap, giving the Diamondbacks the lead. He had been 0-for-3 in the game and 1-for-10 since the trade.

"It's about time," Mondesi said. "When you get traded to a new team, you're trying too hard. You have to just relax and play your game."

"After he fell behind 0-2, he kept his nose on the ball and tracked it all the way into the hitting zone, which I think has been his problem since coming here - he was pulling off the ball," Arizona manager Bob Brenly said.

Matt Mantei worked around a two-out double by Ramon Martinez in the ninth for his 12th save. He retired the dangerous Sammy Sosa on a comebacker to end it.

Oscar Villarreal (7-4) pitched a scoreless eighth for the win.

Gonzalez and Junior Spivey smacked solo homers for the Diamondbacks, who snapped a five-game slide overall and notched their first road win since a 6-0 triumph at San Diego on July 18.

"We just haven't been scoring many runs lately and that Cintron home run really energized everybody on the bench," Brenly said. "We haven't had a big hit like that in a long time."

Citron has hit safely in 19 of his last 22 starts.

"I just came to the plate and my idea was just to get on base for Gonzalez and Hillenbrand and (Borowski) threw me a 2-2 slider," Cintron said. "I was able to hit it well and got the game tied so it was a big hit for us."

The Diamondbacks have found runs to be at a premium lately. Their output Saturday was their highest since scoring four in a loss at San Francisco on July 21. Arizona's three home runs tied the amount it had in its previous 13 games.

"All wins are critical for us with the slide we have been in," Gonzalez said. "Two or three runs have been a lot of us and our pitching staff has been holding us in, so we hope our offense gets going and today was a good sign."

This victory certainly came under strange circumstances as a swarm of gnats descended upon Wrigley Field. Many of the 40,304 fans waved the giveaway caps at the gnats.

"That's terrible out there," Gonzalez said. "I don't know what's going on, a lot of guys will have to change their cologne or after shave or something. It's terrible."

Borowski, who blew his fourth save, gave up two runs and three hits and recorded just one out. In Friday's 4-3, 14-inning victory, he surrendered two runs in 1 1/3 innings.

"I wish I could say that I pitched badly the last two days but I haven't," Borowski said. "The results haven't been what I wanted but I haven't pitched bad."

Kenny Lofton and Sosa each drove in a run for Chicago, which failed in its bid to move three games over .500 for the first time since the end of June.

Lofton opened the scoring in the second with a run-scoring double, but Gonzalez's 19th home run tied it in the fourth.

Spivey's 10th homer put the Diamondbacks ahead by one run in the fifth, but Sosa knotted things at 2-2 with a sacrifice fly in the bottom of the inning. Martinez gave the Cubs the lead with an RBI single in the seventh.
