Katie Boulter has the distinction of winning the first 10-point tiebreaker under the Australian Open's new system for determining level deciding sets.

Boulter beat Ekaterina Makarova 6-0, 4-6, 7-6 (6), including 10-6 in the tiebreaker in which the first player to reach 10 with an advantage of two points clinches the match.

In the men's singles draw, the first four sets will feature a seven-point tiebreaker at 6-6, with the final set going to a 10-point tiebreaker at 6-6.

In women's singles play and men's and women's doubles and mixed doubles, the deciding set of three sets will be played with a 10-point tiebreaker at 6-6.

Wimbledon announced in October it will have a standard first-to-seven-points tiebreaker when the deciding set reaches 12-12.

The U.S. Open was the first Grand Slam tournament to introduce final-set tiebreakers, with a first-to-seven-points game at 6-6.

The French Open is the only remaining Grand Sam still decided by a long deciding set by advantage.
