More mass + technique = velocity
You can hit 90 at 145 pounds.
Ah, fair enough. Lifting might help a boy increase mass, though (with proper nutrition and rest).
Here's what strength increase - in the right places and when done without compromising mobility - does do for velocity. Increased muscle strength, especially in the shoulders and among the 10 muscles that support the ucl throughout the forearm, will allow a pitcher's body to handle more stress and therefore allows for increased velocity. Your body simply won't allow the arm to move faster than it can physically sustain. Your system governs and regulate such movement patterns. More strength = greater ability to handle the greater stresses of increased internal rotation that are necessary for increased velocity.
