Girls throw like their fathers
This is more of an observation than anything else. But teaching as many pitching lessons as I do, I’ve had occasion to watch a lot of girls play catch with their fathers. And it’s amazing how closely the throwing mechanics of the daughter reflect those of her father.
If Dad stands face-forward and pushes the ball, so does his daughter. If Dad wraps his arm around his head when he throws, so does his daughter.
I don’t seem to recall that so much with boys. Not sure why — maybe boys receive more training at an early age, or perhaps they just spend more time throwing on their own. It’s my firm belief that to a boy, duck+rock=throwing practice. A girl would never draw the same conclusion.
In any case, whatever the reason, step back and watch sometime. You’ll see I’m right.
For those of you who are fathers, definitely keep that in mind. However you throw is how your daughter is likely to throw. So if you want your daughter to succeed, work on your own throw first. It could help shortcut her path to being the player she wants and needs to be.
