SAN FRANCISCO -- As anticipated, Giants closer Brian Wilson will undergo reconstructive surgery, commonly known as Tommy John surgery, to repair his right (throwing) elbow Thursday.
Famed orthopedist James Andrews will perform the procedure on Wilson, 30, at his Pensacola, Fla., clinic. Giants team orthopedist Ken Akizuki will be on hand to assist. Andrews also handled Wilson's first Tommy John surgery in 2003. Wilson resumed pitching in 2004, made his Major League debut two years later and proceeded to make three National League All-Star teams.
Asked whether Wilson could resume pitching after about a year, which would be an accelerated recovery, Giants head athletic trainer Dave Groeschner remained noncommittal.
"I guess anything's possible, but we'll see after the surgery," Groeschner said.
Wilson pitched erratically but recorded a save last Thursday at Colorado. One day later, he informed the Giants' medical staff of his physical discomfort. The Giants then made Wilson's injury public Saturday while declaring him out for the season.
Right-hander Santiago Casilla has inherited the closer's role in Wilson's absence. Casilla pitched a shutout ninth to save San Francisco's 4-2 triumph Tuesday over Philadelphia.
Manager Bruce Bochy said that he expected Wilson to rejoin the team during its 10-day, nine-game homestand that starts April 27.
