Senzel will undergo season-ending surgery to repair a torn tendon in his right index finger.
Senzel suffered the injury during Friday's game with Triple-A Louisville. He is expected to be fully recovered by spring training, with a chance that he will be back in action for the Arizona Fall League or winter ball if the organization elects to go that route. Across 44 games with the Bats, the infielder hit .310/.378/.509 with six home runs, 25 RBI and eight stolen bases. This is obviously an unfortunate setback for the Reds' top prospect, especially since he was likely to receive a big-league call-up later on this summer.
