Cardinals hopeful Adam Wainwright ready by spring training after surgery

St. Louis Cardinals ace Adam Wainwright underwent surgery to repair his torn Achilles on Thursday and general manager John Mozeliak said there were "no surprises."

"They didn't have to use any extra material to reattach the tendon," Mozeliak said, according to MLB.com. "If the tear is not perfectly straight, there are times where a surgeon may have to use something else to reattach the tendon. But this was not the case."

The surgery was performed by Dr. George Paletta, the Cardinals' former team doctor.

Wainwright's recovery time is estimated to be from nine to 12 months and Mozeliak said he's hopeful the right-hander will be ready for the start of spring training in 2016.

"The key thing is allowing the wound to heal, and that's the most important part," Mozeliak said, according to MLB.com. "I think the message right now is to just be patient. From my standpoint, he's going to be in good hands. He's going to have access to our medical staff day in and day out, and our hope is for the best."

Wainwright suffered the injury Saturday while stumbling out of the batter's box. Wainwright this week came out against the National League adopting the designated hitter in the future to limit injuries to pitchers while batting, despite how his injury occurred.

The Cardinals transferred Wainwright from the 15-day disabled list to the 60-day DL on Thursday.
