Willie Randolph is going with a typical day-after-night lineup for this afternoon’s nationally televised matchup between Mike Pelfrey (pictured) and the Diamondbacks’ unbeaten Brandon Webb. Moises Alou, who just returned Friday from a two-month absence, is getting the day off along with second baseman Luis Castillo as the Mets (15-12) try to win here at Phoenix’s Chase Field for the 15th time in their past 16 games since 2004.

Carlos Delgado is also back in the No. 5 in spot, at least for one day, in this Mets’ lineup:

Jose Reyes SS

Ryan Church RF

David Wright 3B

Carlos Beltran CF

Carlos Delgado 1B

Damion Easley 2B

Raul Casanova C

Endy Chavez LF

Mike Pelfrey RHP (2-1, 4.43 ERA)

Here are Pelfrey’s numbers against the Diamondbacks.

Despite Friday night’s 7-2 loss to the Mets, the Diamondbacks still have the best record in the majors at 20-9. Their lineup is virtually unchanged from the series opener:

Chris Young CF

Stephen Drew SS

Eric Byrnes LF

Conor Jackson 1B

Justin Upton RF

Mark Reynolds 3B

Augie Ojeda 2B

Chris Snyder C

Brandon Webb RHP (6-0, 1.98)

Here are Webb’s numbers against the Mets.

Incidentally, the roof is closed here this afternoon and will remain that way.
