Every season, teams that are irrelevant in the offseason come out of nowhere and take division titles, win postseason games and eliminate other more-favored teams from contention.
This past season, the Washington Nationals, Baltimore Orioles and Oakland Athletics were three teams who were preseason afterthoughts, but all ended up in the postseason. Oakland took the AL West from the two-time defending American League Champion Texas Rangers, who went on to get eliminated in the Wild Card game.
The rise of the Orioles pushed the perennially contending Boston Red Sox into last place and the Nationals took first place from the Phillies, who had won the division in every season since 2007.
Which teams are ready to make the leap into the elite category in 2013?
