Easy, just have a .500 record or better during the regular season and you are in! Teams will qualify for the post season tournament based on their regular season league record. Teams need to have a .500 or better record to advance to the post season.
What is a .500 record? This is just looking at the overall winning percentage of the regular season games. A .500 record means the team had either the same amount of wins as losses, or more wins than losses. This can be calculated by dividing the number of wins by total games played.
