The ACC converted the tournament to a round robin format in 2007.
From TheACC.com: The top two teams from both the Atlantic and Coastal divisions, as determined by conference winning percentage, in addition to the four teams with the next best conference winning percentage, regardless of division, will be selected to participate in the ACC Baseball Championship.
The two division champions will automatically be seeded number one and two based on winning percentage in overall conference competition.
The remaining teams will be seeded (three through eight) based on winning percentage in overall conference competition without regard to division.
All ties will be broken using the tie-breaking provisions Archived 2016-03-03 at the Wayback Machine.
