First, managers hate walks. Therefore, they order pitchers to throw first pitch fastballs. Second, to learn the skills required to throw these pitches require my training and a long time to perfect.

Fastballs come off the ends of the tip of pitche's second and third digits.
Breaking balls come off the inside of the tip of the pitcher's third digit. Screwballs come off the outside of tip of the pitcher's third digit. Four seam fastballs do not fall due to gravity as much as two seam fastballs.

Hitters who hold their bats vertically prefer low pitches.
