PHILADELPHIA — Pat Burrell got a curtain call, Rudy Seanez heard fans chanting his name and Jason Marquis sent the crowd into a frenzy without even being in the ballpark.

Burrell hit a three-run homer in the eighth and the NL East-leading Philadelphia Phillies beat the Atlanta Braves 6-2 Monday night for their 10th win in 11 games.

The Phillies reduced their magic number for clinching their second straight division title to four after the New York Mets lost 9-5 to Marquis, who hit a grand slam, and the Cubs to fall 21⁄2 games back. Philadelphia’s magic number for clinching a playoff berth is three.

“This is the time of year when all the little things count,” Burrell said. “You can’t afford mistakes.”

Kelly Johnson hit a two-run homer for the Braves, who helped the Phillies by winning two straight against the Mets over the weekend.

With the score tied at 2, pinch-hitter Greg Dobbs singled off Jeff Bennett (3-7) to start the bottom of the eighth. Greg Golson ran for Dobbs and scooted all the way to third when Bennett’s pickoff attempt sailed down the right-field line.

After Bennett retired Jimmy Rollins on a sharp grounder to second, Chase Utley was intentionally walked. Jayson Werth then hit a hard grounder to third baseman Martin Prado’s right. Prado made the backhanded play, but Golson beat the throw home, sliding under Clint Sammons’ tag.

“That was a big moment for me,” Golson said.

Braves manager Bobby Cox wasn’t pleased with his catcher’s effort.

“Sammons didn’t get in front of the plate or the guy’s an easy out,” he said.

Burrell ripped a two-out shot off Julian Tavarez to the seats in left to extend the lead to 6-2. Burrell, who came in batting .176 since Aug. 1, came out of the dugout to acknowledge the towel-waving crowd.

The Phillies were four games behind wild card-leading Milwaukee and trailed the Mets by 31⁄2 after losing to Florida on Sept. 10. Then they swept a four-game series against the Brewers at home and followed with a 5-1 road trip.

“I think things can go our way,” manager Charlie Manuel said. “We got five games left. That’s what we’re looking at.”

Fans waved their white-and-red “Fightin’ Phils” rally towels while keeping a close eye on the scoreboard. They stood and cheered when Marquis — Chicago’s starting pitcher — hit a grand slam to give the Cubs a 6-2 lead over the Mets in the fourth inning at Shea Stadium.

The Philly faithful were so giddy they even gave reliever Seanez a rare standing ovation and serenaded him with chants of “Rudy” in the eighth.

Johnson led off the inning with a double to right that just eluded the diving Werth. He went to third when center fielder Shane Victorino kicked the ball for an error.

But Seanez retired Omar Infante on a liner to shortstop Rollins. Jeff Francoeur followed with a high bouncer to Rollins, who threw out Johnson at the plate. Scott Eyre (5-0) came in to get the final out.

Phillies starter J.A. Happ allowed two runs and five hits in 6 2-3 innings. The left-hander beat the Braves last week for his first win in the majors.

“This is what we dream about in the minors, getting a chance to come up and prove ourselves,” Happ said.

Cubs 9, Mets 5

At New York, Jason Marquis became the second pitcher to hit a grand slam against the Mets this season, and Chicago clinched home-field advantage throughout the NL playoffs while damaging New York’s postseason chances.

Struggling to avoid another late collapse, the Mets slipped 21⁄2 games behind first-place Philadelphia in the NL East and had their wild-card lead cut to one game over idle Milwaukee.

Marquis (11-9) drove in five runs and pitched effectively into the seventh, a big game in his hometown with friends and family in the stands. Derrek Lee also homered and Reed Johnson had a pair of RBI singles for the NL Central champions in the opener of a four-game series that could be a postseason preview.

D-Backs 4, Cardinals 2

At St. Louis, Brandon Webb won his 22nd game and Stephen Drew homered to help Arizona creep closer in the NL West.

Three weeks after hitting for the cycle against St. Louis right-hander Joe Pineiro, Drew came within a triple of another and drove in two runs. Conor Jackson had two hits and an RBI for the Diamondbacks, who have won seven of eight and are two games behind the idle Dodgers with six games to go.

Felipe Lopez and Cesar Izturis had three hits apiece for the Cardinals, who have lost 10 of 12. St. Louis’ magic number is one to be eliminated from postseason contention.

Reds 7, Marlins 5

At Cincinnati, Joey Votto homered and doubled, helping the Reds rally from a four-run deficit and beat Florida in a makeup game.

The loss dropped Florida five games behind New York in the NL wild-card race.

Votto hit a go-ahead double during a six-run burst in the seventh inning. Jerry Hairston Jr. drove in two runs with a bases-loaded single to tie it, and pinch-hitter Andy Phillips later delivered a two-run single.
