Santana tossed four innings last Friday in the instructional league in Fort Myers, Fla. He will long toss and play light catch through Saturday, then shut down his activity for the winter with the instructional league ending.
"Johan feels very good and is looking forward to 2012," GM Sandy Alderson said in a statement. "We are optimistic that Johan will be able to begin and maintain a spring training schedule with all other Mets pitchers next February and will be ready for the start of the 2012 season."
Santana underwent Sept. 14, 2010 surgery to repair a torn anterior capsule in his left shoulder. He did not appear in the majors this season.
