Green was called up from Triple-A Scranton/Wilkes-Barre and will start Sunday's game against the Padres, ESPN New York reports.
The Yankees were in need of a spot starter in order to keep CC Sabathia from starting in a National League park, so Green's services will be called upon for at least one start. It was a bit of a mixed bag in Green's only other start in the majors, as the 25-year-old allowed six runs (four earned) over four innings, but he's been terrific in the minors to the tune of 1.54 ERA and will draw a favorable matchup against San Diego.
