When a player goes into a slump, we, as a society, have gotten pretty good at determining the cause. In baseball, slumps are often just bad luck. For his career, Milwaukee Brewers outfielder Ryan Braun’s career batting average on balls in play (henceforth, BABIP) is .302. In 2018 it seemed like every single scorching liner he hit happened to find a glove, and it showed in his stats, as his BABIP hit a career low .274. For his career, Ryan Braun averages a line drive 18.9% of the time, but last year he vastly exceeded that with a LD% of 23.
