45. Justin Dunn

Pitcher for the Seattle Mariners Justin Dunn talks about how he transformed from a runt touching 70 mph as a freshman into the low-90s arm that became drafted out of high school, how the methodology of Alan Jaeger and the implementation of long toss into his routine allowed him to capitalize on his athleticism mechanically and learn how to manage his workload throughout his career, and how simplification of his process and mastery of his secondary pitches have allowed him to develop into a big leaguer.
