Hello crivea24,

Welcome to Physics Forums!
Apply the Law of Conservation of Momentum to the act of pitching a baseball.
[...]
Here's a hint. Assume that at the beginning, before the pitch is thrown, the relative velocities of the ball, the pitcher and the Earth, are all zero. So how does Conservation of Momentum relate the momentums of the ball, the pitcher and the Earth after the pitch is thrown?

(I'm not sure if you are supposed to ignore angular momentum or not, for this problem. But no matter which way you model the system, momentum ends up being conserved, one way or the other. [as long as you model enough of the entire system such that there are no external forces or torques])
