Oliver Perez pitched in front of Jerry Manuel and Dan Warthen, and Manuel said "He's healthy and ready to go."
Perez may be activated as soon as after tonight's game. Josh Thole is in tonight's lineup, but may be sent down after the game in Perez's place.
Perez has been on rehab, and if the Mets do reactivate him, it's not a given he'll start on Thursday. He may be used as a lefty specialist and long reliever to eat up innings.
Mets manager Jerry Manuel did say he'll advocate keeping Thole in the majors.
