SAN FRANCISCO - The San Francisco Giants broke their longest losing streak in four years by handing Al Leiter the worst start of his career.

Barry Bonds homered, and Marquis Grissom homered and drove in a season-high four runs as Giants beat the New York Mets 11-3 Thursday night, snapping a five-game losing streak.

"We broke out today, which is good," Grissom said. "We feel a lot better after losing five. Our attitude stayed the same. This is a well-grounded team and we knew we could work ourselves out of it."

Leiter (4-2) allowed a career-high 10 runs and 13 hits in 4 2-3 innings. He walked two and struck out three.

"I beat myself up pretty hard," Leiter said. "It was a complete mental breakdown on my part."

The Mets lost their third straight, and sixth of eight overall. They are 0-11 in regular-season games at Pac Bell Park. New York split two playoff games at Pac Bell in 2000.

"It was the first time we haven't played well in quite awhile," Mets manager Art Howe said. Al just wasn't sharp tonight."

The Giants ended their longest slide since an eight-game losing streak from May 12-20, 2000, thanks in part to a six-run fifth inning that was highlighted by Grissom's three-run homer.

"I know how great a pitcher he is," Grissom said of Leiter. "He's got a good cutter and he ran it in on me the first two at bats. I just try to catch the ball out front."

The home run, Grissom's fourth of the season, chased Leiter. Neifi Perez added a two-run single and Benito Santiago later hit an RBI single in the inning.

Kirk Rueter (4-1) allowed three runs on five hits in seven innings.

Bonds' solo homer, which cleared the center field fence to tie the game at 2 in the third, was his 11th of the season and No. 624 of his career, 36 shy of Willie Mays for third on the all-time list.

Rockies 4, Expos 2

DENVER - Greg Norton and Ronnie Belliard each had RBI singles, and the Colorado Rockies scored four runs with two outs in the sixth inning to beat the Montreal Expos in a game that was delayed more than two hours due to rain.

Vladimir Guerrero hit his eighth homer of the season for Montreal, which lost for just the third time in 10 games.

Montreal reliever T.J. Tucker (0-1) gave up all four runs.

Todd Jones (1-1) replaced Colorado starter Jason Jennings in the fifth inning after the second rain delay, and allowed two hits in two innings. Jose Jimenez pitched a perfect ninth for his 11th save in 12 chances.

Braves 15, Padres 6

SAN DIEGO - Julio Franco's two-run triple highlighted an eight-run fifth inning for Atlanta.

There was a scary moment when Padres slugger Ryan Klesko - a former Braves star - was beaned by rookie left-hander Horacio Ramirez (3-2) leading off the fifth. Klesko was knocked to the ground after getting hit near the right ear flap on his batting helmet.

Trainer Todd Hutcheson held a compress to Klesko's head, then helped the woozy player off the field. The Braves were leading 10-3 at the time.

Padres pitcher Jaret Wright hit Chipper Jones in the back on his first pitch of the sixth inning. Plate umpire Jim Reynolds warned Wright and both dugouts.

Andruw Jones and Marcus Giles homered as Atlanta improved to 28-13, the best record in the majors.

The Padres (13-28) lost for the 15th time in 18 games and are tied with Milwaukee for the NL's worst record.

San Diego's bullpen is so taxed that Wiki Gonzalez moved from catcher to pitcher in the ninth and threw a hitless inning.

Padres rookie Roger Deago (0-1), making his second start, gave up seven runs and six hits in 4 1-3 innings.

Cubs 4, Brewers 2

MILWAUKEE - Corey Patterson hit a two-run homer off Brooks Kieschnick in the 17th inning Thursday to give Chicago a four-game sweep.

The Brewers set an NL record for strikeouts in an extra-inning game with 24, two more than the previous mark, set by the New York Mets on May 31, 1964, and tied by Cincinnati on Aug. 8, 1972.

Ending what began as a pitcher's duel between Kerry Wood and Ben Sheets, Patterson connected off Kieschnick (0-1) with two outs for his eighth homer.

Kyle Farnsworth (2-0) pitched three innings for the win, and Todd Wellenmeyer struck out the side for a save in his major league debut. Wood fanned 13 in seven innings.

It was the second-longest game in the majors this season. St. Louis beat Florida 7-6 in 20 innings on April 27.

The Cubs, who won their fifth straight, improved to 5-0 in extra innings this year. The Brewers have lost five in a row.

Astros 6, Pirates 2

PITTSBURGH - Richard Hidalgo drove in two runs with a homer and a double, and Houston beat Pittsburgh for the seventh time in eight meetings the last 11 days.

Roy Oswalt (3-4) limited the Pirates to two runs in six innings and helped himself with a double in the seventh, scoring on Craig Biggio's double. Biggio had two RBIs.

Oswalt didn't come out to pitch the seventh after straining his right groin running the bases. The Astros weren't sure is he would make his next scheduled start.

The Pirates have lost 11 of 13 overall, and 10 of 12 at home. Kris Benson (4-5) couldn't hold a 2-0 lead and gave up three runs and six hits in six innings.

Phillies 6, Diamondbacks 4

PHILADELPHIA - David Bell hit a go-ahead double in Philadelphia's three-run seventh inning.

Bobby Abreu and Ricky Ledee hit solo home runs for the Phillies, who snapped a three-game losing streak and avoided being swept for the first time this season.

Matt Williams and Chad Moeller homered for Arizona, which had won three straight.

Rheal Cormier (1-0) pitched the seventh for the Phillies, extending his NL-leading scoreless streak to 17 1-3 innings. Turk Wendell, who worked the eighth, has yet to allow a run in 14 innings this season.

Jose Mesa got three outs for his 12th save.

Oscar Villarreal (3-3) took the loss.
