The 2021 U-18 Baseball World Cup or the XXIX U-18 Baseball World Cup is an international baseball tournament held by the World Baseball Softball Confederation for players 18-year-old and younger held in Bradenton and Sarasota, Florida, USA. The event was originally scheduled in 2021, but due to the COVID-19 pandemic, was postponed to 2022.[1]
First round: The twelve participating nations were drawn into two groups of 6, in which single round robin will occur. The top 3 nations from each group advances to the Super Round, while the bottom 3 nations from each group advance to the consolation round.
Consolation round: The 6 nations in this round play one game against the teams they have not played yet. (example: The 4th placed team from Group A will play the bottom three teams from Group B)
Super round: The format in the super round is similar to that of the consolation round. Each team plays the top three teams from the opposing group. (example: The 1st placed team from Group B will play the top three teams from Group A) The standings for this round will include the 2 games played against the 2 other second-round qualifiers from the team's first-round group, and the 3 games played in the second round, for a total of 5 games. The 3rd and 4th-place finishers advance to the bronze-medal game, and the 1st and 2nd-place finishers advance to the gold-medal game.
Finals: The Finals consist of the Bronze Medal Game, contested by the 3rd and 4th-place finishers, and the gold-medal game, contested by the 1st and 2nd-place finishers.
