With that 2019 data in hand, Anderson appears to have spent the offseason refining his arsenal. It’s hard to say anything conclusive given that he only threw 83 breaking balls in 2020, but the pitch resembled his “best” breaking balls from 2019: per Statcast, it dropped three inches less, to the point that his average fastball actually rose relative to spin-less motion.
