Pitching
Masterson pitches at a low three-quarter arm delivery with a sliding motion, which some compare to Dennis Eckersley's delivery. His pitching arsenal includes a fastball that reaches 97 mph, a sinker, a slider, and an occasional change-up. It has been claimed that his best pitch is his plus-sinker with a heavy drop.
Masterson throws a variety of fastballs that vary in speed and break, with the speeds reaching between from the upper 80s to the mid 90s. The speed of his slider is in the low 80s, and his change-up ranges from 77 to 81 mph. He can vary his sinker at speeds of 84 to 94 mph, sometimes catching batters off balance.
