The only way you can experience realistic pitch movements, as much as the game will allow, is for you to play on Legend at pitch speeds maxed to 10, 2 seams and sinkers will have that snap and fastballs will have that zip. If you are playing DD, or modes where you're forced to play with Default sliders/settings you will be playing arcade baseball, pitch movement/speeds is basically what your grandma would be able to throw at you.
