I would've been dead-set against the idea of any baseball playoff expansion, but Jayson Stark has me sold- why not two wild cards per league, playing a three-game series, with the winner playing the team with home-field advantage?
The way it is now, there's not much advantage to winning the division- but under the Stark System? It would make both the regular season and playoffs more interesting. Sort of like when the NFL used to have the Wild Card Game.
