"Today we celebrate one of the most exciting moments on the road to the Premier12 and the Tokyo 2020 Olympic Games," said WBSC President Riccardo Fraccari. 

"The stakes have never been as high for an international baseball competition and we expect some very high-pressure, intense and exciting games as well as big surprises in the opening round."

An official promotion video, entitled "Is Your Country Ready II", was also unveiled.

WBSC collaborated with WORKS, a UK-based branding agency that has worked on football's World Cup.
