"Riseball Drills"
    Learning to throw the most devastating pitch in fastpitch takes alot of work and practice. Here are a couple of ideas on how to develope a riseball.
    Body Positioning: On a riseball your weight should be down and back and the pitching side should callapse slightly to "get under" the ball. Think about sitting back on a low stool when you try to throw this pitch or think about making a backward "C" from your heel up to your shoulder.
    Practicing Spins in a Short Distance: Because the spin of the ball is opposite of a fastball spin your wrist, fingers and thumb must all do something completely different from what they do on a fastball. I would suggest starting at about 5 feet away from your catcher and try to get the ball to spin backward by just letting your hand move from a foot behind your hip to a foot in front and letting the ball slide off the back side of your fingers and do this till you feel comfortable and successful with the spin. Then move back 5 feet and do the same but swing your arm a little further each way finishing with the thumb out. Repeat this until you get about 2/3 of your regular pitching distance then try to make a full arm circle. All these should be done with a small stride and don't bring your side through (follow through). This process should be repeated till you get to your full distance, then try the release with your full motion.
    Football Drill: Try playing catch with a 12 inch football and throw it like a softball with a full motion at all times trying to make a tight spyral. This movement is very similar to the way a riseball should be released and will help in its development. I hope these ideas help.
