Zimmerman boasts a good reportoire of pitches starting with his fastball. A true plus pitch, he works in the 91-93 range consistently. He has good heavy sinking motion on his fastball and will attack hitters on the lower half of the plate with it.

Zimmerman threw a good slider with sharp, late bite to it in college but has stopped throwing it as much at the instruction of the Washington Nationals. In college, he could throw the pitch in the mid-upper 80s and used it as a good out pitch. It is likely that he will continue to use it sparingly to reduce the stress on his body.

Lagging behind these pitches are his changeup and curveball. His curve is becoming a bigger part of his aresenal with the diminishing use of the slider. He throws a big 12-6 curve that sits in the low 70s. He needs to continue to work at getting consistency out of this pitch and hiding it better. It certainly has potential to be a plus pitch but at the moment sits as an average curve.

His change could also use some work. Like the curve, it could be a good pitch but presently sits average.

Fastball tops out in the upper-80s. Velocity used to be in the low-90s, but because of shoulder, MPH is a little slow. Good slider and change-up.
