Japan enters as the clear favorite to reach the WBC final after a dominant 6-5 semifinal win over Mexico, showcasing Shohei Ohtani's two-way brilliance and Yuki Matsui's clutch relief pitching, extending their unbeaten run. The USA, priced as the next strongest contender following a 14-2 rout of Cuba, leverages MLB stars like Mike Trout and Mookie Betts despite a thinner pitching staff post-pool play. Trader consensus reflects Japan's superior depth and home-region momentum against the Americans' offensive firepower, with rest advantages minimal ahead of the March 21 championship. Historical head-to-heads favor Japan slightly, but upsets remain possible given international volatility and bullpen fatigue.
