Although rain could still wash this one out, the lineups are in for today’s game between the Mets and Dodgers at Shea Stadium in what could be the last chance for Mike Pelfrey (pictured) to stay in Willie Randolph’s rotation. With Pedro Martinez set to return Tuesday in San Francisco, the Mets appear likely to create a roster spot for him by sending Pelfrey to the minors or Claudio Vargas to the bullpen. How Pelfrey pitches today will be crucial.

Meanwhile, neither right fielder Ryan Church (concussion) nor second baseman Luis Castillo (hip flexor/quadriceps strain) are playing today, but both are hopeful of returning to action in Sunday night’s finale of the four-game series.

This is how the 26-27 Mets will look:

Jose Reyes SS

Endy Chavez RF

David Wright 3B

Carlos Beltran CF

Carlos Delgado 1B

Damion Easley 2B

Brian Schneider C

Fernando Tatis LF

Mike Pelfrey RHP (2-6, 5.33)

Pelfrey has never faced the Dodgers, so no numbers are available.

LA, which reached .500 at 27-27 with Friday night’s win and is second in the NL West, will go with the following order:

Juan Pierre LF

Matt Kemp CF

Jeff Kent 2B

James Loney 1B

Russell Martin C

Andre Ethier RF

Blake DeWitt 3B

Luis Maza SS

Chad Billingsley RHP (4-6, 3.68)

Here are Billingsley’s numbers against the Met hitters.
