Heller was recalled from Triple-A Scranton/Wilkes-Barre on Tuesday.
With Anthony Swarzak being placed on the DL, the Yankees opted to bring Heller back to the big club for additional bullpen depth. Heller has yet to pitch in an MLB game, but has been fantastic over 49 games at the Triple-A and Double-A levels this season. After said games, Heller owns a 1.69 ERA and 0.83 WHIP.
