According to Steve Popper of the Bergen Record, Johan Santana has not been progressing in his rehabilitation program, and the team is prepared to shut him down if today’s scheduled throwing session does not go well.

In addition, Popper says the Mets feel they would be lucky to have Santana back at all this season.

In September, David Waldstein of the New York Times said Santana did not have arthroscopic surgery to repair the torn capsule in his shoulder – rather, Dr. David Altchek had to make a full incision, and indicated then it was possible he could miss the entire 2011 season.

Santana, who turns 32 today, went 11-9 with a 2.98 ERA in 199 innings over 29 starts in 2010 allowing 236 total base runners.
