THURSDAY: Nova has chosen to have the TJ procedure, tweets Feinsand.

TUESDAY: The Yankees announced that Nova’s second exam confirmed that he has a partially torn UCL, and that Ahmad has recommended surgery.

MONDAY: The Tommy John epidemic that is sweeping Major League Baseball looks to have another victim, as Yankees right-hander Ivan Nova learned after an MRI this weekend that he has a partial tear of the ulnar collateral ligament in his right elbow, writes Mark Feinsand of the New York Daily News. Feinsand says that Nova will be re-examined today by team physician Chris Ahmad, but the very likely outcome is that Nova will be the 15th pitcher to undergo Tommy John surgery this season.

Nova was roughed up by the Rays in his start on Saturday, but he didn’t feel any discomfort in his elbow until the final pitch he threw, writes Feinsand. Nova said he felt a pop on that pitch and was in denial as he was being removed from the game, not believing himself to be seriously injured and wanting to continue pitching to spare his bullpen.

With Nova likely on the shelf through next spring, the Yankees will test their internal depth. Vidal Nuno could be the favorite to take over in the team’s rotation, though other options such as David Phelps and Adam Warren are present. New York could also look to the waiver wire and continue to get by with a patchwork solution until clubs begin making more reliable arms available on the trade market this summer.

Needless to say, the resurgence of Michael Pineda is now even more impactful for the Yankees. Were it not for Pineda’s health, the club would be fielding a rotation of Masahiro Tanaka, Hiroki Kuroda, a declining CC Sabathia and a pair of the aforementioned internal options. Now, manager Joe Girardi tells Feinsand that he will meet with GM Brian Cashman, presumably on today’s off-day, to determine which of Nuno, Phelps or Warren will step into Nova’s spot.
