So the conventional wisdom is that the change-up should be approx. 20-25% slower than the fastest pitch but as I watch more D1 games on TV with speed readings, you see many pitchers throwing 65-67mph and their change-ups are 40-45mph (or 30-40% slower) and they are effective with the slower pitch. Does the fact that some coaches tell players not to swing at change-ups unless you have 2 strikes on you, account for the effectiveness of slow change-ups?
