Yankees ace Luis Severino is returning to New York to get an MRI and be re-evaluated by Dr. Chris Ahmad after playing catch in Tampa, Florida, on Monday, manager Aaron Boone said.

Severino, who was shut down at the beginning of March due to rotator cuff inflammation in his right shoulder, isn't experiencing pain, but the Yankees want to run tests to figure out why he isn't feeling well enough to hit the mound, Boone said.
