I have a 10 year-old LHP son. He has developed a knuckleball. I did not teach it to him–he just figured it out while playing “wall-ball” in the driveway.
I wasn’t sure how I felt about this when he first showed it to me, but it doesn’t seem to be causing him any problems and he gets a kick out of throwing it–he even put one over the plate for strike three in a game last fall.
Is there any potential harm here?
