Joe Kelly struck out Matt Kemp on an absolutely filthy changeup

Red Sox reliever Joe Kelly pitched a scoreless sixth inning with two strikeouts in Game 1 of the World Series on Tuesday. That success was built on a foundation of a fastball that sat in the upper 90s and even touched 100 mph. But, as is often said, a 100-mph fastball alone isn't enough to dominate Major League hitters.
