Things change in baseball. Sometimes slowly but they change.
On November 22, 2011, a new contract between Major League Baseball and its players union was ratified, and as a result, an expanded playoff format adding two clubs will be adopted no later than 2013 according to the new Collective Bargaining Agreement.
The new format was finalized for the 2012 season on March 2, 2012, and will use the 2–3 game schedule format for the Division Series for the 2012 season only. A new one-game, wild-card round will be added in each league between the teams with the best records who are not division winners.
The new postseason system, which would have allowed the Red Sox and the Braves to avoid their historic collapses. Forced into a one game playoff with Cardinals, the Braves lost 6-3.
The change increases the reward of a winning a division title, but opened the door of the possibility of a third-place team winning the World Series.
