The NL East race just got a lot more interesting.

Greg Dobbs had a pinch-hit grand slam and the Philadelphia Phillies beat the Mets for the eighth straight time yesterday, completing another sweep of sloppy New York with a 10-6 victory. The Phillies pulled within 3 1/2 games of first-place New York. They won 12 of 18 against the Mets this season, including a franchise-best three series sweeps.

Philadelphia, which entered play 1 1/2 back of San Diego in the wildcard race, has 13 games left while New York has 14 remaining.

Carlos Beltran hit a tying, three-run homer for New York, which committed six errors and matched a season high with 11 walks. It was the most errors by the Mets since they had six on September 13, 2002, at Montreal.

David Wright hit a solo homer in the seventh to become the third player in franchise history to reach 30 homers and 30 stolen bases in a season. New York hitting coach Howard Johnson and Darryl Strawberry also accomplished the feat with the Mets.

The Phillies swept four home games from New York in late August, cutting their division deficit to two. The Mets pushed the margin back up to seven last week, then quickly let Philadelphia back in the race again.

Beltran’s 29th homer tied it at 5 in the fifth, but the Phillies responded with five runs in the sixth.

Mets reliever Guillermo Mota (2–2) failed to retire any of the three batters he faced. Pat Burrell walked, Ryan Howard reached on second baseman Luis Castillo’s error and Aaron Rowand walked before Mota was replaced by Jorge Sosa.

Sosa walked Jayson Werth to force in a run before Dobbs hit a 1-2 pitch into the first deck in right for his first career grand slam and third pinch-hit homer. It also was the Phillies’ second pinch-hit slam of the season.

Dobbs also hurt the Mets on Friday night, lifting the Phillies to a 3-2 win with a pinch-hit sacrifice fly in the 10th inning.

Geoff Geary (3–2) pitched two innings in relief of Adam Eaton to earn the win for Philadelphia, which has won six straight at Shea Stadium.

Shoddy play hurt New York all day and throughout the series.

Oliver Perez walked Eaton on four pitches with two outs in the second inning Sunday, loading the bases. Jimmy Rollins hit a grounder to shortstop Jose Reyes, who bobbled the ball and threw it through Castillo’s legs.

Reyes was charged with two errors on the play, allowing two runs to score and stopping his career-best errorless streak at 43 games. Left fielder Moises Alou couldn’t handle Rollins’ fly ball to the warning track in the fourth, allowing the speedy leadoff hitter to reach third on the error. Chase Utley followed with a double to make it 4–1.

New York also made several mistakes during Philadelphia’s 5–3 win Saturday. Castillo was doubled off second on a fly ball to left in the first, and Reyes was thrown out trying to steal third with two outs. Beltran also misplayed Rollins’ eighth-inning line drive into a two-run triple.
