The pitcher takes a bucket of balls and moves to a point just behind the pitcher’s rubber.
She pitches a ball that crosses over the plate.
If it crosses the plate, the pitcher moves back 5 feet and throws another pitch.
She continues moving back in 5 feet increments and increasing the arc of the pitch until she cannot get it across the plate anymore.
The pitcher then moves back to the location of the last successful throw and tosses 3 more.
Measure this distance and try to beat that mark at the next practice.
