The break on the pitch is shorter than that of the curveball, and the release technique is 'between' those of a curveball and a fastball. The slider is similar to the cutter, a fastball pitch, but is more of a breaking ball than the cutter.The slider is also known as a yakker or a snapper. good, hard slider has a slight break across the plate and a slight drop on its plane to the hitter. It is important when throwing a slider, or any breaking pitch in baseball, not to come around the baseball.
