Had an interesting discussion with the Freshman coach yesterday at practice…We were talking about setting his kids up on pitch count limits of 60-75 for the first few weeks of the season while we continue to safely bring along these kids’ arms. The point he made was that monitoring pitches is one thing, but what if 40% or 50% are curveballs? Or sliders? Is that same 75 total pitch limit the most effective way to monitor arms, or should it be adjusted downward or upward depending on the individual pitches each different pitcher throws?
In other words, is 75 pitches, all fastballs more or less taxing on the arm than a pitcher like a lefty who throws 35 curveballs and 40 fastballs which still add up to 75 total pitches?
I didn’t have an answer, other than to say we will not allow these kids to throw more than 20% breaking pitches. My goal for the freshman pitchers is to have them develop their fastballs and changeups first! Something we were both completely in agreement with. But it’s something to consider as coaches nonetheless! What do you think? How much of a factor, if any, should the types of pitches a pitcher throws come into play when deciding his pitch count limit (if you set one for your pitchers).
