Jeff Karstens Announces Retirement
Former Pirates and Yankes right-hander Jeff Karstens took to Twitter yesterday to announce that he has officially retired from the baseball.
Karstens, still just 32 years of age, hasn’t pitched in the Majors since 2012, as a series of shoulder injuries that culminated in 2013 surgery to repair the labrum and rotator cuff in his right shoulder slowed and ultimately ended his career.
