The Mets will honor their 1969 world champions tonight, then try to deal the first-place Phillies another Citi Field loss when Tim Redding takes the mound against impressive young right-hander JA Happ.

Redding is making his first start since being moved back into the rotation following Thursday’s release of Livan Hernandez. Redding, though, is considered merely a temporary solution, and Jerry Manuel has said the veteran righty will be evaluated on a start-to-start basis.

Redding and the Mets face a considerable chore in Happ, who is 9-2 with a 2.66 ERA in his first full season in the majors. On the plus side, Happ is 0-1 with a 5.03 ERA in five career appearances against the Amazin’s. Here is the 57-65 Mets’ order for the scheduled 7:30 p.m. game:

Angel Pagan CF

Luis Castillo 2B

Gary Sheffield RF

Jeff Francoeur RF

Fernando Tatis 3B

Daniel Murphy 1B

Omir Santos C

Wilson Valdez SS

Tim Redding RHP (1-4, 6.53)
