who has won the most world baseball classic
World Baseball Classic A total of 20 nations have competed in the WBC proper, with 14 appearing in all four editions. Japan has been the most successful, as the only nation with multiple WBC titles (2006, 2009), the nation with the most wins in WBC play (23), and as the only nation to reach the championship round in all four WBCs. The Dominican Republic owns the best overall winning percentage in WBC games at .750 (18-6 record), bolstered by its 8-0 mark en route to the 2013 title. A surprising first-round elimination in 2009 stands out as the Dominican's only poor showing.
