The World Baseball Classic is an international baseball tournament sanctioned from 2006 to 2013 by the International Baseball Federation and after 2013 by the World Baseball Softball Confederation. It was proposed to the IBAF by Major League Baseball, the Major League Baseball Players Association, and other professional baseball leagues and their players associations around the world. It is the main baseball tournament sanctioned by the WBSC, which grants the winner the "World Champion". It previously coexisted with Olympic Baseball and the Baseball World Cup as IBAF–sanctioned tournaments, but baseball has not been on the Olympic program since 2008, after it was voted out by the International Olympic Committee in 2005. The final men's Baseball World Cup was held in 2011, and was discontinued to streamline the international calendar. The 2013 Classic, the third edition of the event, was won by the Dominican Republic in an all-Caribbean World Baseball Classic Final.
The tournament is the first of its kind to have the National Teams of IBAF's member federations feature professional players from the major leagues around the world including Major League Baseball.
