Unlike a typical double-elimination-style bracket, if the winner's bracket champion -- who would be 2-0 at the time -- falls to the loser's bracket champ (who is 2-1), there would be no additional game. This means a team could finish with only one loss, but still miss out on qualification if it loses the final game.
The winner-take-all style should create plenty of drama, with one game between the group's two best teams deciding who advances to the World Baseball Classic. The first such game will take place Feb. 14 in the group featuring Australia, New Zealand, Philippines and South Africa.
Twelve teams have already qualified for the '17 Classic, meaning four spots remain available. After February's qualifiers in Sydney, three other four-team qualifiers will take place in Mexicali, Panama City and Brooklyn. They will also use the modified double-elimination format, with each winner advancing to the World Baseball Classic.
