* indicates statistically significant difference p ≤ 0.05
TOB = Top of Back Swing; FC = Foot Contact; BR = Ball Release
Pelvic Rotation: (-) denotes towards throwing arm side; Trunk Extension = reported as (-); Trunk Flexion = reported as (+); Trunk Lateral Flexion: (+) denotes towards throwing arm side; Trunk Rotation: (+) denotes towards the glove side, (-) denotes towards throwing arm side.
