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 . </P> <P> Along with Japan, three other nations have advanced to at least the second round in all four WBCs: Cuba, Puerto Rico, and the United States . Despite having access to more MLB talent than any other nation, Team USA posted an underwhelming 10 - 10 overall record through the first three WBCs, with only one appearance in the semifinals . The Americans broke through in 2017, going 6 - 2 on their way to their first WBC title . Cuba lived up to its history of strong international play by reaching the finals of the inaugural WBC in 2006 before losing to Japan . However, subsequent Cuban teams have failed to make a significant mark on the tournament, making three straight second - round exits and going just 2 - 7 in second - round games since 2009 . Meanwhile, Caribbean rival Puerto Rico made consecutive appearances in the WBC finals in 2013 and 2017, albeit losing both, and stood second to Japan for the most all - time WBC wins (20) after the 2017 tournament . </P>
