"The CTBA continues to be a key partner for the WBSC and we are grateful for their expertise and hospitality in putting on another great event and an unforgettable experience for all the teams and players who will compete here," Schmidt added.

From the six teams in the super round, the top two will advance to the final, with third and fourth playing for the bronze medal.
