Nova (elbow) hopes to begin throwing off of a mound soon, CBS New York reports.Nova has been throwing on flat ground at the Yankees's minor league complex, and has reported not feeling any pain or tightness after undergoing Tommy John surgery last April. While it's still too early to peg an exact timetable, the 27-year-old said that he is optimistic he'll be back by June at the latest, which would be right in the middle of the typical 12-to-15 month window returning from Tommy John.
