Amanda Scarborough is talking about it's not about how many pitches you throw but having 3 pitches you can throw really well. Someone disagreed saying pitchers can and should master several pitches or they will get rung up. She said her 2 daughters are able to do just that. So, I of course looked at her fb page. At least one of her multiple pitch mastering daughters is playing 10u. I laughed and laughed.
