Jason Bay homered twice and Pittsburgh scored a season-high nine times in the second inning to back Sean Burnett's first career shutout and help the Pirates to an 11-0 win over the Montreal Expos last night in San Juan, Puerto Rico, before 7,436.

Burnett (3-2) scattered 10 hits, struck out three and walked none, helping to shut out Montreal for the 13th time this season. It was Pittsburgh's fourth shutout.

Bay went 4 for 5, with a single, double and two homers. He drove in four runs, hitting solo shots in the fourth and the sixth. It was Bay's third multihomer game of the year and the fourth of his career.

Pittsburgh sent 15 batters to the plate in the second, got seven hits and scored nine times, chasing Expos starter Shawn Hill.

Bobby Hill tripled with the bases loaded when Carl Everett lost track of the ball in the lights. Hill scored on Jason Kendall's grounder and Bay hit a two-run single in his second at-bat of the inning. Tike Redman hit two run-scoring singles in the inning and Randall Simon also had one.

The Pirates' previous season-high was eight, done June 27 against Cincinnati.

* PHILLIES 7, BRAVES 6: Tomas Perez's pinch-hit, RBI single in the 10th helped host Philadelphia overcome a five-run deficit and two three-run homers by Rafael Furcal to beat Atlanta.

Chase Utley hit a solo homer off John Smoltz with one out in the ninth to tie it at 6 and Mike Lieberthal had four RBI, including a three-run homer in the eighth.

* METS 6, MARLINS 3: Ty Wigginton homered and had an RBI double, leading visiting New York to victory. Mike Cameron also homered for the Mets, who scored four runs in the eighth to win for the seventh time in nine games.

* CARDINALS 6, CUBS 1: Jason Marquis kept visiting Chicago reeling and St. Louis got home runs from Edgar Renteria, Albert Pujols, Jim Edmonds and Tony Womack.

Greg Maddux (7-7) gave up three of the homers as the Cardinals won their ninth in a row at home, including the first seven games of a nine-game homestand.

* REDS 3, BREWERS 0: Aaron Harang tied his career high with 10 strikeouts and Wily Mo Pena homered in visiting Cincinnati's win over punchless Milwaukee.

Since spending most of June on the disabled list with a sprained ligament in his right elbow, Harang (5-2) has allowed just one earned run in 182/3 innings.

* ASTROS 3, DODGERS 2: Andy Pettitte outpitched former teammate Jeff Weaver and also drove in a run, and Jose Vizcaino's tiebreaking RBI single in the eighth helped visiting Houston to victory.

* GIANTS 8, DIAMONDBACKS 3: Moments after Barry Bonds matched his major league record for intentional walks with No. 68, this one courtesy of Randy Johnson, Luis Gonzalez dropped Edgardo Alfonzo's bases-loaded liner to left field for an error that allowed the go-ahead runs to score in San Francisco's home victory.
