Tournament

The competition had eight teams divided in two groups. In each group, each team played against all others once and the two best advanced to the semifinals. The best team from Group A will play the second team from Group B and vice versa. Ties within a group were broken by the team allowing the lowest number of runs to pass to the knockout round. The competition began on July 14, with the finals on July 19 (rescheduled to July 20 due to rain).
