They will get laughed off the field in college. It is amazing how once they get to that level all of the nonsense quickly goes by the wayside. For my DD it is long toss, walk throughs, and then get down to business with a full motion. If she struggles with a pitch she may get close to the catcher, isolate her lower body and work on the release/spin for a few minutes.
Too many pitchers spend valuable warmup time doing pointless drills. I spent some time last weekend with a Big 10 coach who was a fixture in the mens game. Talking pitching, he knew of my DD and asked how much time I had her and my other students spend on drills? When I told him next to none it was obvious that he was pleasantly surprised.
I think the best response to the wrist flip question is from Bill Hillhouse when he demonstrates an overhead wrist flip while asking why they do not do that before throwing overhand.
What i have learned from the best of the best instructors that keep us in line around here, is that a forced wrist flip will impead the natural energy of the whip. A looser wrist will flip faster. can someone now explain how the wrist articulates the different spins with this in mind?
My DD does not do wrist flips when warming Up. And I wouldn't be happy if she started.
But on the flip side (no pun intended), for almost every team she's been on, the coach's have always had each player on the team get on a knee and do little overhand wrist flips to warm up there throwing. When did this get started? Do coaches see another team doing it and think, that looks smart, lets loosen up the wrists. It drives me nuts, but I chalk it up as a waste of a few minutes of practice time.
The wrist doesn't articulate the different spins. The fingers do.
