All the World Cup games scheduled for Wednesday in Panama were lost to rain. As a result, most teams are playing three games in the next two days.
Team USA plays Australia at 12 noon Central, then has a doubleheader Friday with games against South Korea and Venezuela. Canada is scheduled to play a doubleheader Thursday, facing Venezuela and South Korea before facing Cuba at 3:30 on Friday. The Cubans, the Cup's lone undefeated team, plays the Netherlands (the only one-loss team) on Thursday, after the Dutch play Australia earlier in the day. Cuba's doubleheader is on Friday with Canada and Panama.
The entire schedule is available here on IBAF's website.
