Sanchez had a biceps tenotomy, which provided more relief from pain. It's essentially the surgical equivalent of what Edgar Renteria did during the playoffs against Atlanta, when he tore his bicep away from the tendon taking a swing during a game.
"We tried to rehab for three to four weeks to avoid this, but after several different opinions we decided —especially with the calendar — to go ahead and scope the shoulder," Giants trainer Dave Groeschner told the Tribune. "Basically, they cut his bicep tendon and cleaned up the back of his shoulder. He had no repairs or anything.
"I think he'll be behind in spring training because he'll be rehabbing, but I think all the doctors he saw agreed that he should be back pretty quickly from there and he'll be able to play baseball games in March, for sure."
Sanchez had three different opinions on the shoulder, including two orthopedists the Giants employ and an independent one in Los Angeles. The Giants' orthopedist in Arizona, Dr. Gary Waslewski (son of the former major league pitcher by the same name), performed the 30-minute procedure.
"It's always a concern when you have to do surgery for a second time on the same body part, but I think talking with the doctor after the surgery, he was pretty pleased with the results," Groeschner said.
Had the Giants not played all the way through the World Series, Sanchez might have avoided the surgery.
"If we had more time and we didn't play the whole month of (October) we could have given him some more time for treatment and rehab," Groeschner said. "But we don't, so we had to do something, and Freddy was on board. He just wants to get better and be ready for the start of the season."
The Giants aren't sure how the injury might have occurred.
