Another baseball pitching tip...

You must be able to throw a change up. Most good high school, college and professional hitters try to anticipate the fastball. They'll sit on the pitch because they can drive it. But if you show that you can effectively change speeds, you instantly make it more difficult for a hitter to anticipate the pitches he's looking for.

Hitting is timing. To be good at pitching, you must disrupt that timing. Develop a quality change-up - and don't stop working on it until you're confident enough to throw it for strikes in 3-2 counts.

Practice it....
