Where's Barry? He could probably explain this better than me.
Each league has 4 teams playing in 2 different playoffs giving you two winners, who then play each other, and that winner goes to the World Series.
Stay around and, perhaps you can learn as the playoffs begin. They begin as soon as the season is over. There are just a few games left to play, and many of the playoff spots are still up in the air. That's because it's been a really tight race.
My team, the Cubs, are really making me sweat.
