Not until she has mastered her change up and spotting her fastball. I hate when pitchers tell me they can throw 5 pitches but can't hit their spots with the fastball and don't throw hard enough to make anything move.
I agree. I may show a student different pitches but our main focus during all pitching sessions are hitting spots with velocity and establishing a reliable change up. If I see the girl getting bored I'll show her something but it normally takes an entire season plus time in the winter to develop a pitch that is reliable enough to use regularly in a game.
I strive for 70% in game situations. Some girls are gym pitchers and achieve this goal practicing but fall apart with a batter, umpire, and a host of other distractions. That's why I challenge them to mature in the heart and mind while pitching with me during the winter. I try to help them in the learning curve by simulating game situations throughout the practice session.
For a talented player that willing to practice, my goal would be to achieve the fastball and be working on a change up the 1st year, develop a solid change up and show her 2 more the 2nd year, 3rd year a drop and curve, and 4th year a screw and riseball. If they start with me at 10 years old, they should have 3 pitches mastered to their young ability by high school freshman age. By junior year, they should be able to throw them all and be the highlight of the Kent St Camp!
Oh wait, I guess I fell asleep there for a moment. What did I write?
