National team appearances in the World Baseball Classic

This article lists the performances of each of the 23 national teams which have made at least one appearance in the World Baseball Classic.

In 2013, Canada and Chinese Taipei re-qualified while Panama and South Africa were respectively replaced by Brazil and Spain.

Other teams to have reached the quarterfinals (previously the second round) are Chinese Taipei (2013), Italy (2013, 2023), Israel (2017), and Australia (2023).

[citation needed] The WBC does not hold a third-place playoff, so the ranking of the third- and fourth-placed teams is determined by the WBSC.

Japan owns the best overall winning percentage in WBC games at .789 (30–8 record), bolstered by its 7–0 mark en route to the 2023 title.

Along with Japan, three other nations have advanced to at least the second round in all five WBCs: Cuba, Puerto Rico, and the United States.

Cuba lived up to its history of strong international play by reaching the finals of the inaugural WBC in 2006 before losing to Japan.

Cuba did make it back to the semifinals in 2023, only to suffer a blowout loss to Team USA in the countries' first-ever WBC meeting.

The worst performance of defending champions was by the Dominican Republic in 2017, eliminating in the second round (now the quarterfinals).
