Barry Bonds took care of the little stuff while A.J. Pierzynski hit the big home run last night to give the Giants a 7-2 win over the Montreal Expos in 11 innings at San Juan Puerto Rico.

Bonds, who had thrown out a runner at home earlier in the game, drove in the go-ahead run in the 11th, hitting a simple fielder's choice to second for a 3-2 lead.

Two batters later, Pierzynski went deep, driving the ball through the muggy San Juan night for the five-run lead.

"I've been trying to hit better pitches, and find pitches I can hit," Pierzynski said. "They finally made a mistake."

Pierzynski had six RBIs, one short of his career high, and hit his third career grand slam. It was only his second homer of the season, however. His lack of production, plus a newspaper story earlier this month quoting three unnamed pitchers as calling him a "cancer" in the clubhouse, have made him very unpopular among Giants fans.

Asked if he felt less pressure batting with the lead in the 11th, instead of the game tied, Pierzynski said, "I've hit into so many double plays this year, and the worst I could do was hit into one more."

Tyler Walker (3-0) pitched the 10th and 11th for the win.

Giants starter Jerome Williams, a former Waipahu High standout, allowed six hits and two earned runs in seven innings. He struck out three and walked two.

• Dodgers 7, Braves 4: Jeff Weaver took a shutout into the eighth inning and visiting Los Angeles ended an eight-game losing streak with a victory over Atlanta.

Jason Grabowski hit a two-run homer in the Dodgers' four-run third inning. Alex Cora had an RBI triple and a solo homer.

Weaver (3-5) was in control before giving up a three-run homer to pinch-hitter Dewayne Wise in the eighth.

• Cubs 7, Cardinals 1: Glendon Rusch filled in just fine for injured Kerry Wood as host Chicago scored four times in the first inning for an easy victory over St. Louis.

In his second start for Wood, Rusch (2-0) gave up a run on six hits and struck out nine in 7á innings.

Derrek Lee's two-run double sparked the first-inning surge and Todd Hollandsworth hit a two-run homer off Woody Williams (1-5) in the third to put Chicago ahead 6-1.

• Marlins 11, Diamondbacks 2: Luis Castillo's first career grand slam capped an eight-run third inning, leading Brad Penny and host Florida past Arizona for its third straight victory.

Arizona's Luis Gonzalez singled in the first for his 2,000th career hit, but All-Star slugger Richie Sexson aggravated his shoulder injury with a check swing.

Penny (5-2) allowed one run and five hits in six innings, lowering his ERA to 2.10.

• Pirates 3, Brewers 1: Josh Fogg (2-4) allowed one run on five hits in six-plus innings, and Pittsburgh broke a tie by scoring two runs without a hit in the bottom of the sixth to beat Milwaukee.

Craig Wilson led off the inning with a walk and was forced out at second on a grounder by Rob Mackowiak, who stole second base and then third as Jason Bay was walked. Bay took second on a wild pitch, and Abraham Nunez's groundball to second scored Mackowiak.

Pitcher Ben Sheets then fielded a grounder by Tike Redman and threw the ball over first baseman Lyle Overbay's head and into the stands for an error, scoring Bay.

• Padres 9, Phillies 6: Brian Giles homered for the third straight game and his aggressive slide in the sixth inning forced a two-run error, leading visiting San Diego over Philadelphia.

Justin Germano went five innings for the win in his first major league appearance. Germano allowed four runs, five hits and four walks, but struck out five.

• Mets 5, Rockies 4: Ty Wigginton hit a go-ahead, two-run homer in the eighth inning to rally host New York past Colorado.

The Mets scored three runs in the first inning, highlighted by Kaz Matsui's fourth leadoff homer of the season, but fell behind 4-3 before coming back against Vladimir Nunez (3-2) in the eighth.
