Keeping your head up

how do you cure the problem that hideki okajima has where he cannot keep his head up while he is about to throw

Lots of reminders and practice. But if that doesn’t work, one trick is to tell the pitcher to throw sidearm. They probably won’t lower their arm slot all the way to sidearm but enough to get the head upright.

i wouldnt consider that a problem
it gets his arm up and the batters arent used to seeing that motion
it gives his pitches a little extra break

plus he has worked with that delivery his whole career
he gets his head up in time not to get hot shotted
