After the Rays acquired Jalen Beeks from the Boston Red Sox for eventual World Series martyr Nathan Eovaldi, it was clear that his changeup would become a weapon the Rays employed, but that change in approach has reached an extreme in 2019.
Jalen Beeks has doubled up on his changeup usage this year (18% to 34%) at the expense of his cutter (20% to 6%). This was an anticipated change in that Beeks fessed up that his cutter was going to go by the wayside during Spring Training, but the anticipated offsetting pitch was supposed to be the return of his slider.
