Seriously. I don't get when even people that believe there should be instant replay in baseball always add, "But NOT for balls and strikes!" I would rather an ump have someone in his ear telling him what the K-zone said over any other replay they have in baseball. I think strike zones that differ between half-innings affect way more games than anything else. Are these people that don't want balls and strikes to be included thinking it will be some sort of challenge from the player? Just let K-zone call it. Let the ump stand there and he can give us the result. This. I don't buy any of this "it's part of the game" garbage. The strike zone should be the strike zone, no matter the umpire, the pitcher on the mound, the umpire's mood, or any other factor.
