The Yankees have long been a model team for developing high leverage relievers from their farm system. From Mariano Rivera, to Dellin Betances, to Jonathan Loáisiga they have developed a lengthy track record, making the following exercise extremely interesting. There are a few different candidates with a timeline in the next year or two who have the stuff to get outs in high leverage situations. A few you probably know, but there is one you probably do not.
I am obligated to start with the most obvious candidate, Luis Gil. He stormed onto the scene this year with three scoreless starts to begin his career.
