Snowman,
It has to do with the tournament format. Unless it's changed, the format is total points based upon the results of group games. That said, based on everything I've heard about Lexington, and the historically good teams at Greenville and Wando, I'm thinking it's highly possible for those 3 to swap results in such a way that a 3 game winner from Group A meets a 3 game winner from Group C for the championship.
