A screwball in baseball is a pitch thrown in the opposite direction of a curveball or slider. A right-handed pitcher who throws a screwball breaks from left to right, vice versa for a left-handed pitcher.
It is the reverse of a curve. A screwball from a right handed pitcher will move right and from a lefty it will move left.

A "Screwball" is thrown by a right-handed pitcher, with the holes facing the the left. It is hard to throw a Screwball with a brand new wiffleball, so experiment with scuffing the ball on concrete or sanding it with sandpaper. To throw this pitch you will need to supply a decent amount of force (40+ MPH) and keep the holes spinning completely parallel during the flight of the ball.
