Report: Jake Westbrook had surgery
Dr. James Andrews performed the surgery within the past 10 days in Birmingham, Ala., the newspaper said.
Westbrook, a right-hander, will become a free agent after the World Series concludes. He went 4-4 with a 3.48 ERA in 12 starts for the Cardinals since being acquired from the Cleveland Indians on July 31.
The newspaper report said the surgery would not affect Westbrook's offseason preparation.
