The
Tommy John Twist, as I discuss
in my main article about the topic, is a
movement I have
long expressed concern about; how
you often see the same twist in the wrists of
pitchers who have had or will need Tommy John
surgery.
Shelby Miller Demonstrating The Tommy John Twist
The Tommy John Twist is the result of teaching pitchers -- and throwers --
to follow one of two cues; to Point the Ball at...
Point the Ball at Second Base or Center Field
I orginally referred to this movement

arm side forearm for an extended period of
time will tend to inhibit the external rotation
of the pitching arm, leading to a
Timing problem and, in the worst case,
what I call
Flat Arm Syndrome.
Jack Flaherty's Tommy John Twist and Timing Problem
Second, pointing the ball at second base
reduces or even eliminates the ability of
the muscles of the forearm to take some of
the load off of the Ulnar Collateral Ligament
(UCL), the ligament that is replaced during
Tommy John surgery.
Shohei Ohtani's Tommy John Twist and Timing Problem
One of the more recent victims of the Tommy
John Twist is Alex Reyes of the Cardinals.

in my
analysis of Alex Reyes' pitching mechanics.
