The all important transition
The inside game of over center projection in Javelin, Cricket, badminton, Tennis, Quarterbacking, Baseball field throwing and pitching has evolved towards throwing off of the center of body rotation with your center of mass being projected centered in linear direction. This means at initial forward force the arms, glove and ball must have arrived into linear centering by getting their pendulum swing centered also. The only way directional centering at drive from initial drive to end drive can be achieved is by the ball arrival and proper humeral upper rotation with shoulder alignment then locking at the start of initial forward force. This is the critical mechanic that differentiates the Marshall driveline and field throwing from traditional pitching drivelines; this critical difference is worth up to 300 points when calculating the MTS. From this start the all-important transition can occur.
The main difference in the Marshall top-half mechanic and the traditional one is in the
transition at the back where with the traditional motion the pitcher brings his hand up with his elbow above the hand with the hand on top of the ball, this action leads to the transitional turnover being late, loopy, centripetal and all the rotational energy is wasted into a bad loading position on bone to bone connective tissue UCL instead of muscle to tendon to bone to joint forward to the next muscle and so on Kinetically linked. This incorrect force application leads to then wasted early energy transfer when the elbow comes around then forward as the ball is actually going backwards from “forearm bounce” causing UCL degradation and a shorter drive force and rotational deceleration at ball forward drive. Unfortunately traditional pitching philosophy dictates that the “pie throwing” position is not the way to bring it back and up so this all-important transition cannot be attained.
When the hand is brought up with the thumb up or underneath it gives you a chance to
To fully supinate as far back as you can reach so that you can transition into pronation at initial drive from this farthest back initial force position thru to the finish. From this starting position comes all of the other beneficial linear drive possibilities (velocity and deception) and reductions with injurious drive mechanics and finish mechanics.
This transition is best and most sinuously produced with the Marshall pitch a cutter called the Torque fastball where the hand is driven in the most powerful pronated position creating powerful safe pronation snap from a radial flexed wrist and pronated forearm extension. You should see my High schoolers (16 thru 19 biologically aged) throw the 6 lb ladies shot put with maximal effort with this particular pitch, now that is getting strong specifically.
