The third photo in O.B. Left's sequence tells the tale:
His Head is centered. He has wonderful Pivot Lag (lower body leading the upper from the top) and has executed a beautiful Sweep Release. As a result, he comes into the ball with textbook Left Arm and Right Forearm Flying Wedge alignments.
Left Arm straight.
Right Arm bent.
Left Wrist Flat.
Right wrist Bent.
I have seen his action in person, and believe me . . .
