After Cardinals pitcher Adam Wainwright underwent surgery Thursday morning to repair a torn Achilles, general manager John Mozeliak said the team expects Wainwright to make a full recovery, reports the St. Louis Post-Dispatch.

"Everybody I've spoken to is expecting a full recovery," Mozeliak said. "He's young and he's healthy. People usually come back from this and do well. The doctors feel, that his age, he'll recover fine."

Wainwright, 33, is expected to need 9-12 months to make a full recovery, which Mozeliak said was the initial diagnosis.

"No surprises," Mozeliak said, "which probably was the best news. [The doctors] didn't have to use any extra material to reattach the tendon, so now it's rest and recovery for probably the next six-to-eight weeks."

He added that he hopes Wainwright can be ready for spring training next season.

"The message right now is just to be patient," Mozeliak said.
