The wild card should be a 2 day event. Game 1 on Day 1. Then a double header on Day 2. All taking place at the top wildcard team's home stadium. If the winning team from Day 1 wins again, no need to play Game 3.
So dumb that a team can play a full 162 game schedule, make the playoffs, and then be out in 1 game.
This change would be an awesome way to start the playoffs.
Another idea would be to hold it at a neutral site... the top team would be the home team for all games, but it would be less of an advantage.
