In 2021, both his changeup and curveball produced a swing and miss roughly 40% of the time he utilized them. Those two pitches are the chief reasons for his superb chase rate and above average strikeout clip. According to Baseball-Savant, when hitters chase Montgomery’s changeup out of the zone, they swing through it 47.9% of the time. The curve is the pitch that’s made the most marked improvement, though. Without a huge uptick in usage, the looping curveball lept from a 50% Chase Miss percentage in 2020 to 63.9% in 2021. No one can seem to lay off the enticing pitch, and when the bat leaves their shoulder, it rarely finds the ball.
