The team said the so-called "Tommy John operation" was successful and that the 23-year-old left-hander will miss the remainder of the season as well as part of the 2012 season.
Anderson complained of soreness in his left elbow after pitching June 5 and was placed on the 15-day disabled list two days later, his third trip to the disabled list.
He was 3-6 with a 4.00 ERA in 13 starts.
The surgery was performed by Dr. James Andrews in Pensacola, Fla.
