PITTSBURGH (AP) — Right-hander Jameson Taillon, considered the Pittsburgh Pirates' top pitching prospect, will have Tommy John surgery and will miss the entire season and likely part of 2015.
Dr. David Altchek will perform the surgery in New York at a date to be determined.
Taillon, 22, began feeling pain in his elbow with two weeks remaining in spring training after being assigned by the Pirates to their minor league camp. Doctors prescribed two weeks of rest, but Taillon again felt pain when he tried to throw again.
While Taillon does not have a fully torn ligament, Altchek felt it was compromised to the point where surgery was necessary. Taillon will be out 12 to 18 months.
