Selected by the Indians in the 22nd round of the 2013 Draft out of Olivet Nazarene University, Heller struggled to throw strikes early in his career before making strides and reaching Double-A for the first time in 2015. The hard-throwing right-hander continued to climb the ladder in early 2016, earning a promotion to Triple-A in late May after a dominant showing back in the Eastern League.
With his strong frame and a lightning-quick arm, Heller generates easy velocity. He operates in the high 90s and can bump triple digits with his heater, throwing the pitch with late arm-side run that makes him difficult to barrel. His slider pairs nicely with his fastball, registering in the low 80s with good tilt and two-plane action, and together they've helped him to pile up strikeouts at every Minor League stop so far.
Though his slider requires some additional refinement, Heller's two-pitch combo, as well as the strides he's made commanding them, could have him working out of the Indians' bullpen sooner rather than later.
