johnny appleseed,
not quite. but it's my fault.
bad illustrations.
what i see is you making contact on a pull pitch with your left forearm not in alignment with the bat (straight alignment at contact).
in the bottom illustration of my first post to you, the left forearm and bat almost form a straight line. not so in the top illustration, where the forearm and bat create an angle (albeit slight).
causes:
the right hand is pushing too hard into contact.
the left shoulder is not pulling back (toward the back of the box)
this is a timing issue as well as mechanical.
can't tell if it's a carry-over into game. need game footage.
suggestions:
do some one arm (left) tee work, and have someone record you. stop action at contact and check alignment. notice power diff when in alignment.
also have one of your pitchers throw some cage BP to you @ 60ft. 6 while trying to stike you out - and record that.
just my two cents. trying to help. don't want to conflict with your instructor. good luck.
