Teams that make it past the Second Round of the WBC could get to play two exhibition games against MLB teams in Arizona. If Japan makes it, they could play the San Diego Padres and Seattle Mariners.
If Japan advances to the Championship Round, they will head to Arizona on the 12th. Practices will begin on the 13th and the two exhibition games will take place on the 14th and 15th.
