With Will Smith, Dustin May, and Gavin Lux, it is easy to overlook the emergence of rookie pitcher Tony Gonsolin last season. The 25-year-old made his Major League debut in June, joining the rotation for a few turns in August, pitching effectively, earning a 4-2 record with a 2.92 ERA/3.86 FIP, along with an 8.32 K/9 compared to 3.38 BB/9 over 40 innings.
For pitching enthusiasts, what stood out the most about Gonsolin was his split-finger fastball. Baseball America ranked Gonsolin’s split, which they categorize as a changeup, the best among righty prospects in baseball.
