After years of flirting around the 1.00 mark in the GB/FB department (meaning he always had at least as many groundballs as fly balls) New York Yankees‘ catcher Gary Sanchez morphed into a full-on flyball hitter, with a 0.67 GB/FB ratio.
While that recipe is usually good for home runs (more flies equals more dingers) batting average usually suffers, especially when the batter is as slow as Sanchez (23rd percentile sprint speed.)
As a result, his batting average dipped to .232 and his BABIP (batting average in balls in play, which excludes plays such as walks, strikeouts and homers) was a paltry .
