It's not a round though..it's a blink. You play 162 game season for it to end with a Dan UGGLA error, an Omar Infante HR, or Joe Blanton unexplainably finding his best stuff for one day? Baseball is and always has been the law of averages. You run hot, you run cold, and over enough time the numbers bear out what you are. A one game play-in is the exact opposite of that. I understand what you're saying about wanting to reward the division winners, but a one game play-in is a mockery to me. Make four divisions or two divisions and eliminate the WC all together if you want to "punish" that team.
