The World Baseball Classic started as a cockamamie idea in Bud Selig's noggin, but it's turned out to be quite the sucess. The last two finals were held in San Diego and Los Angeles, respectively, and in 2013, the powers that be are sticking with California, awarding the semi-finals and final games to San Francisco and AT&T Park.
The World Baseball Classic used to be held every three years, before the International Baseball Foundation switched the format to every four years. The 2013 games will be the first since 2009, which were won by Japan for the second consecutive tournament. The finals were held at Dodger Stadium in front of over 54,000 people -- a near sell-out.
