* Double-round eliminations; 14 games per team; Teams are then seeded by basis on win–loss records.
* The two teams at the bottom of the standings after the elimination round will be eliminated. The top two teams will advance outright to the semifinals.
* The next four teams will qualify in a single round-robin quarterfinals; the top two teams will advance to the semifinals.
* Semifinals will be a double round-robin affair with the four remaining teams.
