Lately, I've been growing increasingly uncomfortable with my
existing method of classifying arm action flaws. I have been
feeling that the terms
Inverted W, Inverted L,
and Hyperabduction don't
accurately characterize all of the types of flaws that I see.
Jensen Lewis' Inverted V
The photo above of Jensen Lewis is a perfect example of an
Inverted V. Notice the fairly conventional GS arm orientation,
but the PAS elbow well above and behind the level of the
shoulders in a position of Hyperabduction and the PAS hand at the level of the shoulders.
A significant Inverted V, and a resulting timing problem, is what you see in the clip above, and photo below, of Joel Zumaya.
Joel Zumaya's Inverted V
You can also see an Inverted V in the arm action of a number of other pitchers.
Billy Wagner's Inverted V
Aaron Heilman's Inverted V
Jake Peavy's Inverted V
This generally puts their elbows and shoulders at greater risk, although some of this risk can be mitigated by pitching out of the bullpen.
