PHILADELPHIA -- Brett Myers tossed seven gritty innings, Jimmy Rollins had three hits and two RBI, and the Philadelphia Phillies completed their first four-game sweep of the Los Angeles Dodgers in 23 years with a 5-0 win Monday night.

Philadelphia remained a half-game behind the NL East-leading New York Mets with its eighth victory in 10 games since losing four straight at Dodger Stadium. The Mets visit Tuesday for a two-game set.

It was the Phillies' first four-game sweep over the Dodgers since Aug. 29 to Sept. 1, 1985, at Los Angeles. Philadelphia had never swept the Dodgers in a four-game series at home.

Mets 9, Astros 1

NEW YORK (AP) -- Carlos Delgado hit a pair of three-run homers and Mike Pelfrey pitched his second straight complete game, leading New York over Houston.

Jose Reyes also had a big night at the plate, and Pelfrey came within two outs of his first major league shutout. The six-hitter followed his first career complete game, when he allowed three hits in a 6-3 victory over Atlanta last Wednesday.

Cubs 12, Pirates 3

PITTSBURGH (AP) -- Aramis Ramirez hit a three-run homer and Chicago beat Pittsburgh to improve baseball's best record.

Two slumping hitters, Jim Edmonds and Kosuke Fukudome, also had big games as the Cubs moved to 81-50 -- the first time they've been 31 games above .500 since they ended the 1984 season 96-65.

Rockies 4, Giants 2

SAN FRANCISCO (AP) -- Jeff Francis got his first victory in more than two months, Yorvit Torrealba homered and the Colorado Rockies won for the eighth time in 10 games, beating the San Francisco Giants 4-2 on Monday night.

Francis was winless in his last five starts but maintained his recent domination of the Giants by allowing seven hits over seven innings and repeatedly pitching his way out of trouble after giving up two runs in the first inning.

Padres 4, D-backs 2

SAN DIEGO (AP) -- Jody Gerut hit a two-run homer off Jon Rauch in the bottom of the ninth inning, and the San Diego Padres snapped a seven-game losing streak by beating the Arizona Diamondbacks 4-2 Monday night.

The loss kept first-place Arizona three games ahead of Los Angeles in the NL West. The Dodgers lost 5-0 at Philadelphia.
