CJ Kayfus underwent season-ending surgery on Friday to repair a broken right ankle.

Kayfus suffered both a fracture and ligament damage in his right ankle while playing for Triple-A Columbus last Saturday. The 24-year-old former top prospect was demoted to the minors back in mid-April after hitting just .182 (4-for-22) with one homer and two RBI over nine games in a bench role. There is no timeline for his return but he figures to be ready for the start of spring training.
