MIAMI — Mike Pelfrey will try to snap the Marlins’ hex over him this season when he leads the Mets against Florida right-hander Ricky Nolasco here tonight in the second game of a three-game series at Dolphin Stadium. Pelfrey has challenged Johan Santana for the designation of staff ace in the second half, winning 11 of his past 13 decisions, but he is an ugly 0-3 with a 10.66 ERA in three starts against the Marlins this year. Pelfrey will be opposed by Nolasco, who is 1-1 with a 3.48 ERA in four starts against the Mets in 2008.

As for the lineup, no changes by Jerry Manuel tonight after Friday’s gripping, 5-4 comeback win in the ninth inning that was powered by Carlos Beltran’s eighth career grand slam. Manuel did say, however, that he would be willing to pinch-hit more for right fielder Ryan Church with Church hitting just .188 in his past five games.

The Mets’ bullpen also could be short-handed tonight, with Manuel revealing that Duaner Sanchez (knee), Scott Schoeneweis (back) and fill-in closer Luis Ayala (groin) are all nursing injuries.

Here is the overall order for the 75-60, first-place Mets:

Jose Reyes SS

Luis Castillo 2B

David Wright 3B

Carlos Delgado 1B

Carlos Beltran CF

Ryan Church RF

Daniel Murphy LF

Brian Schneider C

Mike Pelfrey RHP (13-8, 3.70)

The 68-67 Marlins, who are in third place and seven games out in the East, are going with:
