Rehabbing pitchers progressing

John Maine is expected to throw 85 pitches on Friday with Triple-A Buffalo, in his second rehab start in the minors. Based on how he performs for the Bisons, Maine could rejoin the Mets' rotation after that outing or be asked to make one more minor league start.

Meanwhile, Oliver Perez is facing batters in a controlled setting in Port St. Lucie, Fla. Former major league catcher Mike DiFelice, who is slated to manage Kingsport when its season opens next week, is catching Perez at the team's complex.

Reliever Sean Green, who was diagnosed with a fractured rib and has been out since mid-April, is slowly working his way back. Green now has twice thrown a baseball on flat ground.
