Changing Pitchers: Price, Nola, and Cahill
I’ve been writing some variant of this pitcher transformation article from the beginning of spring training containing information from spring training velocities to pitch mix changes. With a new pitch or extra velocity, a pitcher can quickly change from one talent level to another. With the season now in full gear, the major preseason changes are known but now it’s time to start finding those pitchers who are slowly transforming themselves mid-season. Every week I hope to focus on these pitchers.
David Price
The 33-year-old Price continues to be a fastball/changeup pitcher. He keeps hitters off guard by throwing three different fastballs (cutter, sinker, four-seam). As his velocity has dropped, he’s started relying on his changeup increasing its usage from 14% in 2017 to 22% last year and finally 29% this year. The pitch has been dynamite with a 21% SwStr% and helped propel his strikeout rate from a 9.1 K/9 last year to career-high 10.5 K/9 this season. He’s pulling the old-man trick of throwing his non-fastballs more to stay relevant.
Rant: I’m not sure why pitchers wait until they start declining to make the change. Why not make the change immediately and become an ace.
