Ueno has no hips, and throws around her body, much like a batter would use pelvic twist to give them rotational momentum in their swing. If you've ever coached youth, and had girls pitch like this (it's fairly common unfortunately, For some reason some instructors release the ball at the seam on the side of the pants) you have all kinds of problems when they hit puberty. They either give up because they get tired of smacking themselves or they develop crazy lean, sideways pelvic tilt, or non-linear arm whips to get "around" the issue. If they stayed open in the first place they would never have had to make this adjustment. I'd never want a girl to be taught to pitch like Ueno pitches. . . sure, she gets results, but you wonder how many kids have ended up with health issues trying to emulate her.

Your post comes off as a "scare tactic".
Ueno, despite being short, is an incredibly accomplished pitcher. IMO she is doing a lot correct, and IMO you do a disservice to the pitching community when you scare people away from sound mechanics without factual information for doing so.
Try again ... what exactly is Ueno doing that allows her to throw at 70mph, despite having short levers?
