Ok here they are, and mind you they both have the same arsenel:
Fastball= high outside
Change = slow roller
Drop= just bad
Screw= one of them throws this well
Curve= the other one throws this well
Screw change = again one throws this well
Rise= Catcher refuses to give the sign, she hates running to the backstop to get it.
Drop curve= By this time I'm overwhelmed and never call it.
Ok... I've been reading through all these posts and I have to comment.
First... A pitcher can throw a screw, drop, curve, rise, change, or fastball. THAT IS IT!!!!!!!
Second... Changing speeds on a pitch is
NOT a different pitch. It is still the same pitch. That is called pitching when you try and confuse the hitters timing with a speed and location change on the same pitch.
I have been through the mill with my daughter. She graduated college(DII) last spring and paid her way through it with her pitching. The only pitches she had was a great rise, average drop, great curve, very good screw, and fair change. If I counted that she threw all the pitches at different speeds she would have been throwing 15 different pitches, not including a fastball that she quit throwing in games at 14. For her college career she averaged 7.8 K's per 7 innings. Her highest was 10.6 her soph year. The last time a gun was put on her was in her junior year in HS. She was throwing a legit 63 mph. I did clock her once with a real police radar gun when she just turned 14. She was throwing 59-60 mph at that time. Never had a gun on her in college. By then it was all about movement, not speed.
At 12U there are very few pitchers who can legitimately make the ball move in all four directions. It takes a year to learn how to really throw a REAL breaking pitch so that it ends up where you want it most of the time. Not a spinny fastball at a spot. My daughter learned her pitches in this order. Rise from 12-13. Drop 13-14. Curve 14-15. Screw 16-17. She also worked on several different changes through the years with varying success. During the last two years of HS and through college she would work on two different pitches each time she practiced. Before a tournament she would work on them all throwing a simulated game with me calling balls and strikes. It worked well for her. It kept her pitches sharp and it also helped with her ability to move from pitch to pitch during a game. It also helped with having to make adjustments on the fly during a game.
Speed is great. Movement great. Changing speeds is great. When you have a pitcher who can do all three you have a pitcher, not a thrower. The final piece to being successful in the circle is knowing which pitch to throw a hitter to get the result you want in a given situation. Too many coaches at the younger levels who call the pitches have no idea how to control a hitter to get the needed results in different game situations. Too many of them call pitches like there are no runners on base.
