I remember playing a carnival game where the customer threw three pitches at a target and a radar gun posted the speed of each pitch. The catch was that the customer only saw the speed of the first two pitches and had to guess the speed of the third one. He had to get it right in order to win a prize. Most of the people I watched didn't even get close. It's hard to know how fast a ball will go from pitch to pitch. I had more fun just learning I could still throw a 75 mph fastball at my age.
