Johan Santana to throw off mound

PHILADELPHIA -- New York Mets left-hander Johan Santana, who was shut down with shoulder discomfort days after tossing three scoreless innings in a July 28 rehab game with Class A St. Lucie, was scheduled to resume throwing off a mound in Port St. Lucie on Tuesday.

The Mets have not written off Santana appearing in one major league game before the season's end, although the window is narrow for Santana to get enough pitching in to be ready.

"Too hard to say," a team official said.

Santana is trying to return from Sept. 14, 2010 surgery to repair a torn anterior capsule in his left shoulder.

He long-tossed a baseball at 100 feet Monday in anticipation of resuming mound work Tuesday afternoon.

The hope is Santana will get in one official minor league rehab game before those seasons end the first week of September. Santana then could pitch in the fall instructional league in his hometown of Fort Myers, Fla., and even in a comparable fall league in the Dominican Republic afterward.

With the Mets' season ending Sept. 28, the likelihood is Santana will not appear in a major league game, but it's not being written off.

Winter ball in Venezuela is an option open for discussion, but that is several steps down the road and assumes Santana progresses uninterrupted at this point.
