Nobody has ever asked me to make a first pitch. IF i was ever asked i would have to warm up my arm for half an hour, and i would throw a strike (probably) and look good doing it. However if i ran out to the mound cold and just threw that first ball in front of 70,000 fans the ball might not make it to home plate. The first three or four throws are painful and all over the place as my arm is old cold and traveled.
My 1st couple of throws feels like sand in my rotator cuff. 25 years of high school baseball batting practice has taken a toll.
