Before Game 1 started, the St. Louis Cardinals had 2.3 to 1 odds to win the World Series 2011.
After Game 1, the Texas Rangers have a 2.1 to 1 odds to win the World Series 2011.
To hedge this you would have place a bet on both of these equally. And you would have expected Chris Carpenter and the Cardinals to win Game 1. In which they did.
These odds were shown on Intertops.
If you had these bets in. You would have made profit no matter which teams win the series.
