Workouts for baseball pitchers?

Hello. I am also a competitive baseball player... And I am now 15 years old. My fastball is now maxing out at around 82MPH and averages around 79 - 80 MPH.... I am 6'4 and 225 pounds and the speed definatly came from the workouts that I have been doing. You Physique sounds just like what mine was last year... I went to the 90 MPH Club and signed up... It cost a bit of money but It helped me throw about 5 MPH harder over the summer. Check it would help out alot.
