The 23-year-old will have the surgery performed by well-renowned surgeon Dr. James Andrews and this injury is a huge blow to the organization.
Williamson was selected in the third-round of the 2012 draft and smacked 25 home runs last season with a .292 batting average at Class-A San Jose. He was batting .318 this year with 27 hits, three home runs and 11 RBI's in 23 games.
He was placed on the disabled list last week and recovery time will be shorter compared to pitchers who have had Tommy John surgery. Los Angeles Dodgers outfielder Carl Crawford had the surgery back in August 2012 and was playing eight months later.
