One of the off-season topics for the St. Louis Cardinals is the
question of the shortstop and whether Tyler Greene is someone that
can count on or whether, as they did in 2011 with Ryan Theriot
and Rafael Furcal, they need to find another option.
Based on what I see in Tyler Greene's swing, I don't believe
that, over the course of a full season, Tyler Greene is going to
be able to deliver significantly better numbers than he has
delivered over the past three years. Let me explain why I say that.
The clips above shows Tyler Greene hitting a home run to left
field. While this ball went a long way, I have some concerns
with the hitting mechanics that Tyler Greene used to hit this
The first thing that I see in the swing of Tyler Greene is
something that is relatively easy to fix. The thing to notice is
how much Tyler Greene's back foot moves. That is an indication
that Tyler Greene is bleeding off energy and may have to swing
harder as a result. That could be a good thing because it
indicates that, if Tyler Greene was able to fix this problem, he
could swing just a bit easier and, perhaps, improve his average.
The biggest thing that I see in Tyler Greene's swing is a
fairly serious problem with his back
The thing to notice is how, as he starts his swing, Tyler
Greene's back elbow slides forward of his hands. This is something that you don't see in the swings of
high-level hitters. Instead, good hitters tend to keep their
hands forward of their back elbows because that improves
their leverage and helps to keep their swings short.
Albert Pujols' Swing
However, you do see this pattern in the swings of hitters
who hit well through the AAA level but who struggle at the
major league level.
The clip above shows the back arm and elbow of Matt Pagnozzi.
He has yet to manage to hit well at the major league level.
His swing shows the same pattern; notice how his back elbow gets
ahead of his hands for several frames.
Another Leaky Back Elbow
The clip above, of a client of mine, shows the same pattern.
Notice how his back elbow slides forward of his hands and his
back hip. This lengthens his swing just enough that, while
he is able to hit well at the AAA level, he still hasn't managed
to get this flaw out of his swing and struggles to hit well at
the major league level.
I have spent a significant amount of time working with the
hitter above and suggesting ways of dealing with his problem
with his back elbow. Given that he hasn't been able to fix this
problem, you have to wonder if Tyler Greene will be able to fix
his problem and will ever live up to his billing, at least at
