Katie Boulter has created some history at the Australian Open but not before a hilarious gaffe after her first-round win.
On her first appearance in a main draw of a Grand Slam outside of Wimbledon, the 22-year-old put in a solid performance.
British No. 2 Katie Boulter scored a freakish and brilliant first-round win over Ekaterina Makarova, an experienced Russian with a fine record in Melbourne, after playing the first-ever 10-point tie-break to be contested at a grand-slam singles tournament.
However she appeared to celebrate at 7-4 in the super tie-break, confused about the new format.
To Boulter's credit, she quickly regrouped after the confusion and went on to claim a 6-0, 4-6, 7-6 (10-6) victory over Makarova, an accomplished 30-year-old opponent who reached the semi-finals here in 2015.
Katie Boulter celebrated her first round win a little early forgetting the new tie-break rules.
Boulter will face No 11 seed Aryna Sabalenka in the second round.
She remained calm after losing the second set and held her nerve when serving at 6-5 down in the third, with four fearsome serves to clinch the game to love.
The British No 2 arrived at Melbourne Park on the back of securing a deal with David Beckham's and Neymar's agent, Simon Oliveira.
