Teams that are classified as Major in the USSSA rankings are eligible to play in Sportsplex baseball tournaments listed as AAA (playing up), Open, or Majors.
- Major teams must play up at least one age division. Example: 10-year-old Major teams must complete in the 11-year-old AAA division or higher in order to enter the tournament.
- If a Major team wins a AAA tournament, it becomes ineligible to enter another AAA event at the Sportsplex for the rest of the spring and summer season.
- Major teams may enter AAA one event at a time. Multiple tournament entries will not be allowed because they may block AAA teams, which should have first priority in these events.
