The U-18 Baseball World Cup is the 18-and-under baseball world championship sanctioned by the International Baseball Federation (IBAF) and its successor, the World Baseball Softball Confederation (WBSC), and was first held in 1981 in the United States. Because it is a world championship, the results of the U-18 Baseball World Cup affect the WBSC World Rankings. [1]
