The Problem with a
Injury problems directly related to hitting are generally pretty
rare. Yes, on occasion you will see hitters develop problems
with their obliques, but these are rarely chronic or
career-ending. However, there is one thing that does seem to
increase the risk of developing shoulder problems.
A one-handed finish.
To be clear, I
like one-handed finishes. Among other things, they can keep
hitters from cutting their swings short.
However, the picture above of Hanley Ramirez (which is NOT
photoshopped) shows the
problem with a one-handed finish. Notice how his upper arm is
externally rotating and his hand is well behind his coronal
plane (basically, his back). This (obviously) puts tremendous
strain on the shoulder, and I have seen labrum problems in
hitters who have one-handed finishes.
The problems tend to fall under the umbrella term of
If you choose to use a one-handed finish, you need to be sure to
not cut your shoulder rotation short and you need to not let
your bat hand get behind your shoulders. If you cannot do this,
and/or if you have problems with your non-throwing shoulder, you
should consider using a two-handed finish.
