Important

Players are responsible for checking their schedule of play one day before the tournament. Failure to attend a scheduled match may result in a default.

Authority

The STA Tournament Supervisor / Referee shall act as final on-site authority for the interpretation of the applicable STA Tournament Rules & Regulations, ITF Code of Conduct and Rules of Tennis. Abuse of officials by parents may result in suspension of the player's future STA tournament participation.

1.1 Competition Format

All events shall be played on a Round-Robin system.

1.2 Orange Ball: 10-Under Format

Match Format
  • All matches will be played on a time-based format of 6 minutes.
  • If scores are tied after 6 minutes, players will play one deciding point to determine the winner.
  • Players will change ends after every 6 points played.
  • The format of play may be changed at the referee's discretion.
Serving Order & Scoring
  • The serving order is in 1221 format.
  • The first server, Player A, serves 1 point.
  • Service switches to Player B, who serves 2 consecutive points.
  • Service switches back to Player A, who serves 2 consecutive points.
  • Service switches to Player B, who serves 1 point.
  • This completes one 1221 serving cycle.
  • After changing ends, the 1221 serving pattern continues, with the next point served by the player who served last.
  • The winner earns 1 point for winning the match.
  • Simple numerical scoring is used: 1, 2, 3, 4... instead of the traditional 15–30–40 system.

1.3 Round-Robin Ranking Method

Players are ranked based on their number of match wins. The player with the most wins is ranked highest.

Two players tied

The tie will be decided by the head-to-head result, with the winner ranked higher.

Three or more players tied

If the head-to-head results do not determine the ranking, players will be ranked by their percentage of total points won across all Round-Robin matches.

Calculation: Total points won ÷ Total points played × 100

The player with the higher percentage will be ranked higher.

If the player who was left out would have been seeded, the error in seeding may be corrected by switching the positions of the affected players. The seeding positions will remain.

If a player is defaulted for not showing up for a match because of an administrative error, the Referee can reinstate the match and players must play the reinstated match as scheduled by the Referee.
