Multi-line team tennis is Sports Axiom's team format: two teams meet in a fixture, and the fixture is made up of several lines — a configured mix of singles and doubles courts. Each line is a normal tennis match; the team that wins the majority of lines wins the fixture.
Lineups
Team captains submit a lineup per fixture, assigning players to lines under the event's lineup rules. Substitutions between fixtures follow the organizer's published replacement policy.
Standings
Team standings count fixture wins first. When teams are level, the configured tie-break sequence looks at total line wins, then set and game ratios across the tie, mirroring how individual round-robin tie-breaks work.
Scores per line
Every line goes through the standard authoritative score flow. A fixture result becomes final when all of its lines are official.
Sports Axiom events follow the standard rules of tennis unless the organizer publishes event-specific modifications on the event page. The International Tennis Federation is the rules authority for the sport itself; Sports Axiom links there rather than reproducing rulebook text.
