ST. LOUIS -- Barry Bonds was smack in the middle of everything -- driving in runs, scoring them and even flashing his temper in the NL championship opener.

Bonds delivered yet another big hit, lining a key triple and later getting embroiled in a skirmish that nearly turned into a real slugfest as the San Francisco Giants beat the Cardinals 9-6 Wednesday night.

In a postseason that is rapidly becoming all his own, Bonds went 1-for-2 with three walks. The four-time MVP, known in the past for his playoff failures, hit three home runs against Atlanta in the opening round.

Benito Santiago, batting behind Bonds, homered and drove in four runs, and Kenny Lofton and David Bell also connected. It was 6-1 after three innings as the Giants tattooed Matt Morris, and it was a good omen for them -- the team that has won the last nine NLCS openers has gone on to reach the World Series.

It was the way Lofton admired his shot, however, that led to a high-and-tight pitch the next time around, emptying both benches and bullpens.

Lofton had to be restrained by several teammates, a coach and an umpire after spinning away from reliever Mike Crudale's fastball in the fifth inning.

As players sprinted toward the plate, Bonds and Cardinals reserve Eduardo Perez had to be separated, with Cardinals reliever Steve Kline pacifying the Giants slugger.

Managers Tony La Russa and Dusty Baker, who a day earlier gushed about how much they liked each other, started screaming in a heated exchange that forced a pair of umpires to pull them apart.

About the only one to keep cool as Kirk Rueter. Born and raised right across the Mississippi River, he kept winning at the ballpark where he rooted for the Cardinals as a kid.

The big lead enabled the Giants to hold off a rally fueled by home runs from Albert Pujols, surprising Miguel Cairo and pinch-hitter J.D. Drew. Robb Nen pitched the ninth for a save.

Game 2 is tonight with Woody Williams, who hasn't pitched since Sept. 20 because of a pulled muscle in his left side, starting for St. Louis against Jason Schmidt.

Busch Stadium, full of red and ready to erupt from the start, quickly grew silent as Lofton led off the game with a walk and, after an intentional walk to Bonds, scored on Santiago's two-out infield hit.

Morris retired the first two batters in the second, then suddenly lost it. Lofton singled, stole second and scored on Rich Aurilia's single. Kent followed with a single, and that brought up Bonds.

Bond caught up with a hanging curve and lined a one-hop drive off the right-center field wall for a two-run triple, and an RBI single by Santiago made it 5-0.

Lofton struck again with a solo homer in the third, standing near the plate to watch his drive sail over the right-field fence. The speedster casually flipped his bat aside before beginning his trot.

Bell's solo homer made it 7-1 in the fifth and finished Morris. One batter later, the trouble started.

Crudale's first pitch came close to Lofton -- not at his head, but too close for Lofton. Lofton shouted at Crudale before starting to yell at catcher Mike Matheny.

It took a few minutes to restore order, with Giants reserve Shawon Dunston, who formerly played with the Cardinals, eventually settling down Lofton. Dunston also stepped away with his teammate and showed Lofton how he had styled after the home run -- Dunston seemed to disagree with Lofton's imitation, but the point was made.

The 52,175 fans cheered loudly when Lofton flied out, and the crowd was revved up the rest of the way.

Pujols hit a two-run homer in the fifth, but Santiago offset that with his own two-run homer in the sixth for a 9-3 lead.

Cairo, starting in place of injured Scott Rolen, hit a two-run homer in the bottom half. The hit made him 7-for-7 in this year's playoffs.

Drew added a pinch-hit homer in the eighth.

Notes: Rueter is 5-0 in nine regular-season starts at Busch. ... Paul McCartney was in town, giving a concert a few blocks away. Cardinals president Mark Lamping invited the former Beatle to take part in the festivities, but the singer couldn't make it. ... Texas Tech basketball coach Bob Knight, one of La Russa's close friends, was in the Cardinals' clubhouse before the game. ... St. Louis 1B Tino Martinez was 0-for-13 in this year's playoffs before singling in the sixth. ... The last time a team won the NLCS opener and didn't go to the World Series was 1991, when Bonds and the Pirates beat Atlanta in Game 1.
