Once you watch it often and you start picking it up then you really start to appreciate the skill and athleticism involved. Batting looks pretty simple, but a 90mph fastball gives the batter something like a third of the second to see it, decide what pitch it is (was it a slider, curve, fastball etc), if it's a strike or a ball, if it's a strike where in the strike zone will it be, what movement it has and to have hit it.
