Every efficient pitching delivery will exhibit some degree of shoulder tilt. Shoulder tilt as I have repeated many times before is a “result” and not an “action”. When the back foot drives the back hip away from the pitching rubber the shoulders will “tilt” as a result.
What should not happen is the shoulder tilt occurring before knee lift because then it becomes an “action” and not the “result” of driving the back hip away from the pitching rubber.
Shoulder tilt should be maintained as the delivery progresses forward to foot touch. The degree of the slope will start to level off as the foot plants so the shoulders can work around the spine to create the shoulder angle.
The shoulders create the arm angle delivering the throwing arm along the angled pathway they created.
The photo above is a great illustration of maximum efficiency along the shoulder line.
Mariano Rivera and Justin Verlander utilize the same degree of their slope from shoulder tilt to shoulder angle.
In other words, if Rivera has a 15 degree shoulder tilt then he will have a 15 degree shoulder angle.
This is how the elite utilize their shoulders working off the spine generating tremendous leverage to deliver the throwing arm.
Analyze your pitchers to make sure they are utilizing the line of the shoulders properly to enhance efficiency.
When the proper shoulder tilt (or shoulder angle) is consistent it will most importantly help with arm safety but at the same time increase velocity, accuracy and command. This alone can unlock your potential as a pitcher in a short amount of time.
