Cat Osterman (current USA Olympic team pitcher) wrote a college theme paper in which she studied the effect of a step back versus a non-step back aproach to pitching. Her conclusion was that the step back neither added or subtracted from the speed of a pitcher's pitch. | |
---|---|
1. | Cat Osterman studied a step back with the use of an arm swing (which was legal at the time). The new rules require you to keep both hands together and the ball in your glove during the step back. By taking awaing the arm swing you have negated any thrust you get with your upper body |
2. | Any step back, requires you to straighten your ball hand foot (pivot) prior to starting your forward motion. When pitchers step backward they now have all their weight on the glove hand foot and rarely shift their weight back over their ball hand foot before pushing off the mound. This negates the strong push you get from a loaded (bent) ball side leg. |
3. | It is very hard (near impossible) to load (bend) your ball hand knee prior to pushing off the mound if your weight is behind the mound on the step back. |
4. | By not loading (bending) your ball hand foot you are unable to have a strong push which helps you propell your hips through your pitch and keep your weight over the balls of your feet With a weak ball hand foot push and a strong glove hand foot push, the pitcher tends to have their weight transfered to their heels rather the balls of her feet. Also the week ball hand foot push is usually late, with a straight leg, no power, and tends to drag the pitchers ball hand foot like an anchor, making it almost impossible to power your hips through and finish your arm follow through. Think of throwing over hand, would you ever throw hard and leave your foot draging behind you? |
