The Yankees’ rotation is absorbing another significant blow with the news that right-hander Clarke Schmidt appears likely to undergo Tommy John surgery, manager Aaron Boone said before Saturday’s Subway Series game against the Mets at Citi Field.

Yankees pitcher Clarke Schmidt likely needs a second Tommy John surgery that would sideline him for the remainder of this season and much of next year, a huge blow to New York’s injury-riddled rotation.

One day after he was placed on the injured list with forearm tightness, it was determined that New York Yankees right-hander Clarke Schmidt likely will undergo Tommy John surgery. Yankees manager Aaron Boone told reporters Saturday afternoon that Schmidt has a tear in the ulnar collateral ligament of his right elbow.
