Pitching Mechanics Analysis Michael Pineda

There has been extensive discussion among Yankee fans about whether new
Yankee pitcher Michael Pineda has the Inverted W or not. The bottom line on
Michael Pineda's pitching mechanics is that I do not see the Inverted W in
Michael Pineda's pitching mechanics, but I do see some things that concern me.

First, Michael Pineda doesn't have a classic Inverted W. While his elbows do
get a bit high, it's borderline at best.

You can see some hints of a timing problem in the two pictures above, and in
the picture directly above in particular. The thing to notice is how Michael
Pineda's arm is passing through 90 degrees of external rotation but his glove
side elbow has pulled back significantly and his shoulders have rotated
significantly. That suggests that his arm is a bit late.

You can see the same thing in the pictures above of Michael Pineda; notice
how his Pitching Arm Side (PAS) forearm is vertical and at 90 degrees of
external rotation and his Glove Side (GS) elbow is well behind his back. That
is often an indication of a timing problem.

However, what Michael Pineda does isn't as drastic as what Stephen Strasburg
does; notice how much later Stephen Strasburg's PAS forearm is. Strasburg's
PAS forearm is closer to horizontal whereas Michael Pineda's PAS forearm is
closer to vertical, which is a significant difference.

What concerns me the most about Michael Pineda's arm action is that he seems
to show the ball to Center Field. Many people teach this, but it's both
unnecessary and potentially injurious.

If you look at high speed clips of Michael Pineda, you can see his PAS
forearm rotate around at the last second as gets his hand into position to
throw the ball. That late torqueing can create a timing problem and can
increase the load on both the elbow and the shoulder.

In the high-speed clip above, notice how he shows the ball to Center Field
and how this causes his arm to be late and appears to create a timing
problem. He also does all of this with his PAS elbow quite high, and possibly
above the level of his shoulders in a position of Hyperabduction.

推 lolity:因為「標準」的姿勢是W(ex.Maddux)，所以稱不標準姿勢為倒W
