For once, try to educate yourself on WHY "palm to the sky" is important. No one who has actually read BM's Internal Rotation thread could come up with a different conclusion which tells me you HAVE NOT read it. Have you done the simple drill where you hold your arm out from your body and rotate your palm to the sky and then to the ground and back up to the sky 5x as fast as you can? Your hand will BLUR because this is the fastest action in the human body. Use it to your advantage when pitching.That's further down than 9 oclock or 3 oclock and that's probably a curve ball. The hand is more vertical at the 9/3 (righty to 3rd for pitches, such as riseball). And I have looked at multiple pictures (video is blurry or bad angle), often of the same pitcher, and the hand is at 3rd, not the sky. Many of the top PCs in the nation, say it is at 3rd (see RiBa video on this site) so let's stop this silly argument. To the sky is for spinning the ball. A 9 year old does not need to do it.
Palm to 3rd at 9:00 is like taking a three quarters swing versus taking a full swing with "palm to the sky". Why cheat yourself from generating more spin and velocity?
