2:53pm: The MRI showed inflammation to Severino’s rotator cuff, MLB.com’s Bryan Hoch tweets. He’ll rest for at least two weeks while undergoing treatment, including injections and anti-inflammatories, before picking up a ball. That’ll likely knock Severino out for Opening Day, though it seems the broader prognosis is still generally optimistic.

1:26pm: Severino is going to go in for an MRI, skipper Aaron Boone says (via Kristie Ackert of the New York Daily News, on Twitter).

12:39pm: The Yankees announced today that prized righty Luis Severino would miss his scheduled spring outing. He had begun to warm up but experienced “discomfort” in his pitching shoulder, per the team.

The level of concern is not yet apparent, but the 25-year-old is due for a closer look from medical personnel. Per the team’s announcement, Severino “will undergo further evaluation this afternoon.”

Severino is a key piece for the Yanks, who’ll need all their best players at full strength to do battle with the other American League super-teams. The club’s starting five is set, presuming they all make it through camp unscathed, with the next layer of depth consisting of 40-man members Luis Cessa, Domingo German, Jonathan Loaisiga, and Chance Adams along with non-roster invitees Drew Hutchison and David Hale.

No matter the outlook, Severino is earning a guaranteed $40MM under the contract he and the team struck last month. He has been one of the game’s most productive starters over the past two campaigns, working to a 3.18 ERA with 10.5 K/9 and 2.3 BB/9 over 384 2/3 frames.
