postseason begins, only telling you a player's ERA or batting average or whatever since the start of the postseason (or even since the start of the World Series).

For example, tonight's starting pitchers and Bumgarner (0-0, 0.00 ERA) and Shields (0-0, 0.00 ERA). Their stat lines are full of zeroes because they haven't recorded any stats in the World Series yet.

No kidding! Why don't they just tell us what their stats were during the regular season. That's the information we care about.
