I currently throw a 4-seam FB, 2-seam FB, splitter, circlechange, knucklecurve, and a 12-6 curveball. My circlechange is slower than my fastball (I'm not sure how much slower, but I know it's slower). My circlechange isn't straight like a fastball but sometimes moves like a curveball (straight down) or sometimes it curves away from righthanded batters (I'm a righthanded pitcher). Should the circlechange be straight like a fastball or have curveball movement like mine does?
I throw my circle with my thumb and index finger forming the "circle" and my middle finger and ring finger on the ball with a 2-seam grip and the pinky is just touching the ball on the side.
This site shows the circle change thrown differently:
Is their actually a difference between the 2 considering movement and speed?
Does anyone know to throw a Vulcan Change such as the one Eric Gagne uses?
Does anyone know how to throw a screwball?
