A cutter is thrown most effectively with a three-quarters delivery and a heavy snap of the wrist. A left-handed pitcher has an inherent advantage against left-handed hitters with pure fastballs, so the development of a cutter to throw to RH hitters is imperative. An ideal cut curve ball will look like a pitch outside and only 'cut' into the strike zone in the last four feet of its flight towards the catcher's mitt. Once the pitch is dialed-in, the ball goes from being a 'take-all-the-way' pitch because it's high and outside, to being called a strike on the inside edge of the plate with the catcher digging it out of the dirt. It's a devastating pitch that often causes a right handed batter's knees to buckle and only able to generate a hapless swing out of pure futility.
