Your head should be rotated looking at the pitcher and your knees slightly flexed. Your hands should be gripping the bat with your middle knuckles aligned and brought up to ear height and held directly above your back shoulder.

2. Shoulder Girdle: While in the Stance the left shoulder girdle will Abduct (protract), while the right shoulder girdle Adducts (retracts) using the middle/lower fiber of the trapizius and rhomboids to support the bat and elevate it to the proper height.

(pronator teres) The left elbow is elevated and flexed.(Biceps brachii, brachialis, and shoulder joint). The biceps brachii, brachialis and brachio radialis are concentrically loaded and prepared to go to the next step.


5.Hip girdle: Pelvic girdle is slightly tilted anteriorly (Rectus Femoris & Psoas).
