With John Maine on the disabled list, Oliver Perez (pictured) is scheduled to start Friday night against Florida on four days’ rest. The Mets need to find a starter for Saturday, perhaps rookie left-hander Jon Niese. In other injury news, right fielder Ryan Church (post-concussion syndrome) was slated to work out before tonight’s game, GM Omar Minaya said. The Mets are waiting for doctors to clear Church for a minor league rehab assignment.

Second baseman Luis Castillo, on the disabled list with a strained left hip flexor, was scheduled to play a rehab game tonight for Single-A St. Lucie.
