Severino was optioned to Triple-A Scranton/Wilkes-Barre on Wednesday, Newsday's Erik Boland reports.
EDGE Analysis
After a dominant relief appearance against the Mets last week, Severino was thrust back into the Yankees' rotation, but the matchup at Boston proved too difficult for the 22-year-old right-hander. He gave up five runs on seven hits over 4.1 innings Tuesday, pushing his ERA on the year to 6.42, and the Yankees have evidently made the decision to turn back to Chad Green to fill a rotation spot. It's uncertain what role Severino will fill upon his eventual return this year, but there's little doubt he will compete for a starting job in spring training.
