Cut an old bed sheet (or similar material) into pieces 18" by 5". Fold the long side a few times until the cloth is 1" by 18". Form 2 lines, with one line of pitchers down on one knee, resting "glove side" elbow on other knee. Hold arm out (the one resting on knee) parallel to ground (with glove on) no higher than 18" above the ground. Players standing, hold out throwing hand (palm up), draping the folded cloth over their middle finger, and letting it hang down evenly on each side of their middle finger. Loosely holding the cloth in their fist, have pitchers go through normal windups, with the delivery being, slapping their partner's glove with cloth. Check for proper motion, balance and defensive position.
While this partner is rotating their arm in and out the other athlete will hold the KB Powerbands with both hands extended out in front of their body. With knees slightly bent, back straight, and shoulder blades pinched together this athlete will squeeze their abs and hold this position. As their partner rotates the athlete will feel tension build in the abs. Athletes must keep abs tight to avoid being pulled or rotating the hips or arms.
Throw the Blitzball just as you would a regular fastball, but with your two fingers positioned about a half-inch to the outside and the ball should naturally roll off of your index finger to the side when you release it (kind of like throwing a football spiral). This Cutter is thrown just like a fastball with an off-center grip and requires no wrist snapping of any kind. Just make sure that the ball rolls off of the thumb side of your index finger as you release it and the ball should curve sideways a good 3-4 feet (away from a righty batter if you are a righty pitcher and vice-versa).
