Green was recalled from Triple-A Scranton/Wilkes-Barre on Friday.
Green received the promotion with Chris Parmelee landing on the DL with a hamstring strain. The 25-year-old right-hander has been impressive while with the Railraiders, not allowing more than two earned runs in any start this season, which covers 61.2 innings. He'll look to bring that same type of consistency when he takes the hill in the near future for the Yankees.
