WHAT IT MEANS: They’re the comeback kings.

For the MLB-leading 11^th time this season, the Mets produced a comeback victory. It lifted them to a 10-6 win Wednesday at Citizens Bank Park and their first sweep of a three-game series in Philly since June 2006.

The Mets (18-13) moved five games over .500 for the first time since July 19, 2010, when they were 49-44.

The reeling Phillies, at 14-18, dropped four games under .500 for the first time since May 9, 2007 -- exactly five years ago. (Don’t look up how that season turned out in the NL East.)

The Mets had rallied from a 2-0 deficit in Monday’s series opener, then a 4-0 deficit Tuesday for victories. This time, they trailed 4-2 after six innings.

PEN PALTRY: After Cliff Lee departed at 84 pitches in his first outing since returning from the disabled list, the Mets rallied with a three-run seventh against reliever Kyle Kendrick. The first five batters reached, then Andres Torres delivered a run-scoring groundout to give the Mets a 5-4 lead.

Kirk Nieuwenhuis opened the frame with a walk. Justin Turner and Ike Davis consecutively doubled. Rob Johnson walked to load the bases. Then Kendrick plunked pinch hitter Lucas Duda to force in the tying run and set up Torres’ at-bat.

It marked the Phillies’ fifth blown save in their past 10 games.

Kendrick remained in for the eighth and surrendered a leadoff double to David Wright, then broken-bat RBI double to Scott Hairston as the Mets claimed a two-run lead. Later that inning, after Hunter Pence dropped a routine fly ball in right field, Davis launched a mammoth three-run homer off the façade of the second deck in right field against Jose Contreras to give the Mets a 9-4 cushion. It was Davis’ first long ball since April 18, against Atlanta’s Jair Jurrjens.

The Phillies had taken a 4-2 lead in the bottom of the sixth while chasing Dillon Gee on a tiebreaking double by Freddy Galvis and RBI single by Laynce Nix.

HEY THERE MR.: D.J. Carrasco pitched the ninth in his first 2012 appearance with the Mets. He allowed one run.

WHAT’S NEXT: A day off at South Beach for the Mets on Thursday. The Amazin’s then open a weekend series against Jose Reyes and the Marlins on Friday -- their first glimpse at Miami’s new stadium. The opener, which features southpaws Johan Santana and Mark Buehrle, is the 8,000^th regular-season game in Mets history. And, presumably, the 8,000^th game in franchise history without a no-hitter. Reyes went 1-for-12 during the series at Citi Field.
