ATLANTA -– The lineups are in for the Mets’ 7:35 p.m. showdown here with the rival Braves.

Be forewarned, though, because the weather outlook here in Atlanta isn’t promising. Lots of rain in the immediate forecast, so this one might not get in.

If it does come off, the Mets — who have John Maine making his season debut — will field pretty much the same order they’ve been using all week:

SS Jose Reyes

2B Luis Castillo

3B David Wright

CF Carlos Beltran

1B Carlos Delgado

RF Ryan Church

LF Angel Pagan

C Brian Schneider

P John Maine

Here is the Braves’ lineup, with RHP Tim Hudson (0-0, 2.57) on the mound:

SS Yunel Escobar

CF Mark Kotsay

3B Chipper Jones

1B Mark Teixeira

C Brian McCann

RF Jeff Francoeur

LF Matt Diaz

2B Martin Prado

P Tim Hudson
