Thanks. I am of a similar mind. My thought is that a 2 seamer is a great risk management option as moving down in the zone it’s more likely to produce a ground ball. I like a 4 seamer in to increase perceived velocity.
I feel like is a ton of flexibility in a 2 seamer. Deeper in hand to take more off and give it more sink. More index pressure to get more horizontal.
His coach is very focused on sinker and change with my son. Prior to this coach, he wasn’t able to move anything armside. He was supinated early and cut his 4 seam without trying and has a naturally good curveball.
It feels like a more healthy approach to focus on pronation pitches. His arm slot is really deceptive. The ball comes out from behind his head really late and with the amount of layback he has the ball shows late.
Thanks for your thoughts. I love talking baseball and trying to learn as much as possible of the nuance that I never learned as I stopped playing Freshman year when it became clear that D-1 baseball was out of my reach but D-1 swimming was realistic with full time focus (it worked).
