That would be Englishbey Hitting. This would be the equivalent of what Steve Englishbey would call his tall and fall drill. Its not identical but its pretty close.
The bolded part above is the critical. Specifically, what do you find interesting about it?
This is what I found on his home page...
Two Key Elements in an Elite-Level Swing:
(1) generate tremendous explosive power from the middle of their body and
(2) use their upper body in the most efficient way to transfer that explosive power to their bat head.
His "Swing Components" page is coming soon and this is pretty vague, so there isn't much to work with. =) Do you have a video so we can all check it out hit "Tall and Fall" drill?
