MLB to add two more Wild Card teams

Major League Baseball is set to add two more Wild Card teams to its playoff format, an expansion that could occur as soon as next season.

The expansion will be fairly simple. The American and National League will each get an additional wild card team. A one-game playoff will begin the postseason. The playoffs will then follow their current three-round format -- Division Series, League Championship Series, and World Series.

Commissioner Bug Selig said Thursday that MLB would like to have the expansion in place for next season.

With the addition of the two wild card spots, 10 out of the 30 major league teams will make the playoffs.
