First to 9

Definition

First-to-9 is an extended tiebreak format where the first player to reach 9 points with a 2-point margin wins the tiebreak. This is slightly longer than the standard first-to-7 tiebreak (used at 6-6 in games) but shorter than super tiebreaks (first to 10). First-to-9 tiebreaks are used in some tournaments as a middle ground: they extend tiebreak duration for more decisive play while remaining shorter than full-set play. First-to-9 may be used at 8-8 in games or in pro-set tiebreaks. The format is less common than first-to-7 or first-to-10 but appears in some regional tournaments and club competitions. Service order follows standard tiebreak rotation (alternating every two points). First-to-9 maintains the 2-point margin requirement, meaning a 9-8 lead is insufficient; the leader must reach a 2-point advantage.

Origin: Developed as a compromise tiebreak length between standard and extended formats.
