So I've noticed this on a number of occasions this season and it's confusing at best and maddening at worst...
Today, 3-1 count and Votto all but steps out of the box, taking the pitch, before the pitch leaves the pitchers hand. This isn't an isolated example, either. He does this fairly often. I'd think he'd be looking to drive something (one pitch in one spot) on a 3-1 count but he gave up on the pitch before it was delivered.
Now, don't get me wrong, the guy has been the NL MVP thus far, but I just don't understand why he does this. My wife has noticed it as well so I'm not nuts here.
