Jeff Karstens hasn’t appeared in the majors since 2012 due to injury and today he took to Instagram to announce his retirement from baseball:

Karstens, 32, didn’t pitch at all last season while rehabbing from labrum surgery. He’ll finish his career with a 26-40 record and a 4.44 ERA over 91 starts and 47 relief appearances between the Yankees and Pirates. He was a useful pitcher during his time with Pittsburgh, posting a 3.59 ERA with 5.8 K/9 and 1.7 BB/9 between 2012-2013.
