WBCI also announced two changes in the competitive structure of the tournament. The 2009 World Baseball Classic will feature a double-elimination format during the first two rounds of play, as well as the introduction of cross-over Semi-Final games. The double-elimination format takes the place of the roundrobin pool-play system used in the inaugural event. For Rounds One and Two, the first two teams with two losses will be eliminated from the competition, with the two remaining teams moving on. In both rounds, teams in the final game will compete for a Pool Championship prize, as well as seeding in the following round (see tournament bracket below). The winners of each Round Two Pool will play the opposite Pool's runners-up in two single-elimination Semi-Final games. As in 2006, the winners of the Semi-Final games will advance to the one-game tournament Final to compete for the World Baseball Classic Championship.
