The Yankees optioned Gil to the rookie-level Florida Complex League following Thursday's 6-4 win over the Rays.
Gil handed out four free passes in two innings Thursday, leading to an unearned run. He has been used infrequently this month, as Thursday's outing was just Gil's fourth of September. A corresponding move was not immediately announced, but the Yankees figure to add a fresh arm or two ahead of Friday's doubleheader against Baltimore.
