Kopech is planning to throw his changeup more in 2023, Scott Merkin of MLB.com reports.
Kopech has reportedly been working on his changeup this offseason and is hoping the pitch helps boost the effectiveness of the rest of his arsenal, which already includes a fastball, a slider and a curveball. According to Baseball Savant, Kopech threw his changeup only 25 times in 2022 -- primarily using it against left-handed batters.
