SAN FRANCISCO -- Alex Cintron did more than give the Diamondbacks a big boost with his bat. He rushed to help center fielder Shawn Green get away from a female fan who jumped over the left-field fence and ran toward Green and started grabbing at him.
"That was scary," Cintron said after another big offensive night. "I was trying to take her out and help. I didn't see security. She was saying, 'I want your hat.' It looked like she was on drugs."
Cintron hit a tiebreaking RBI single in the eighth and added a three-run double in the ninth, leading the Arizona Diamondbacks over the San Francisco Giants 7-3 on Friday night for their sixth straight victory.
San Francisco police said they arrested a woman, but declined to provide an age, name or hometown. Her gender was being debated in the Diamondbacks clubhouse.
"I'm saying girl, but I wouldn't bet the house on it," Green said. "I'm going by voice."
Arizona players were frustrated by the slow response from security. The woman came on the field in the sixth inning and began throwing her arms before being escorted away by security.
"You don't like to see it because it scares you a little bit," Diamondbacks manager Bob Melvin said. "You never like to see it."
Chad Tracy hit a two-run homer and Andy Green hit a tying sacrifice fly in the seventh for the Diamondbacks, who matched their longest winning streak of the year and won for the ninth time in 10 games.
Cintron lined a single to left against LaTroy Hawkins (2-8) in the eighth, and his ninth-inning hit gave him a career high-tying four RBI. Oscar Villarreal (2-0) pitched one inning for the win and Jose Valverde got Omar Vizquel to line out with two men on for his 14th save in 16 chances.
Randy Winn homered twice, doubled and singled for San Francisco on a night Barry Bonds took off to rest. Winn, the majors' top hitter in September with a .447 average, posted his third career two-homer game and second this year. He also did it Sept. 3 at Arizona.
He hit his ninth career leadoff homer off Claudio Vargas, then connected again in the third to extend his career-high total to 20, 14 since joining the Giants in a July 30 trade with Seattle. Winn was intentionally walked in the seventh. He finished September with 51 hits, the most by a Giants player in any month in more than 30 years.
Rookie Matt Cain, who has a spot in the Giants' 2006 rotation all but locked up, allowed three runs and six hits in 6 1/3 innings, but failed to win only hours before his 21st birthday.
"I have a lot of room to grow," Cain said. "It's been fun to be up here and hopefully I'll be back next year."
Giants manager Felipe Alou is uncertain if Bonds will play the final two games of the year or opt to take it easy on his surgically repaired right knee. The slugger will decide whether he wants to be in the lineup.
"I know Barry doesn't feel that good," Alou said of his superstar, who returned from the disabled list Sept. 12 and has hit five home runs. "I'd like to see maybe one more at-bat."
Fans chanted "We want Bonds! We want Bonds!" with the game tied at 3 in the seventh.
Edgardo Alfonzo stole home on a double-steal with Todd Linden in the second to tie the game at 2. Ray Durham also took part in a double-steal Sept. 5 in Los Angeles.
Alfonzo left in the fourth and was replaced at second base by Angel Chavez.
The Diamondbacks have won four straight road games and eight of 10 for a 40-39 record away from home. They need to win one of their last two games for their first winning record on the road since 2002, when they went 43-38.
Vargas is winless in three starts since a victory Sept. 10 at Colorado.

Diamondbacks LF Luis Gonzalez batted leadoff for just the seventh time in his career and first time since Aug. 10, 1998, while with Detroit -- he homered twice that day.

Giants rookie RHP Scott Munter had arthroscopic surgery on his tender throwing elbow, performed by team doctor Ken Akizuki. Munter went on the DL on Aug. 12 with inflammation in his right elbow. Trainer Stan Conte hopes Munter can begin a throwing program in four to six weeks.
