Alex de Minaur, the fiancée of fellow tennis star Katie Boulter, cracked a silly joke after her big win in the second round of the Australian Open.

Jelena Dokic has pointed to the success of Alex de Minaur and Katie Boulter to slap down suggestions Stefanos Tsitsipas and Paula Badosa have struggled on the court due to their relationship. Tsitsipas suffered a shock first-round loss at the Australian Open after curious footage showed him looking rather glum while talking to girlfriend Badosa behind the scenes.

Katie Boulter and Alex de Minaur, engaged since December, displayed strong couple vibes at Melbourne Park. De Minaur supported Boulter courtside during her first-round match, providing her with significant motivation.

Katie Boulter said she was inspired by her Aussie fiance and supporters after setting a new British record of six first round singles wins at the Australian Open. The British No.1 struggled with the pressure and Canadian world No.98 Rebecca Marino in a nervy nighttime encounter in the Kia Arena.

Katie Boulter became the sixth British player to win their match in the opening round of the Australian Open this year.

He’s shown what an incredible tennis player he is, and he’s ranked (in) top 10 in the world, and has been there for a whole year, which is not an easy thing to do. I’ve learnt so many different ways of becoming a better tennis player.

Katie Boulter had a humbling message for her partner as he prepared for his opening match at the Australian Open. Alex de Minaur will headline the Rod Laver Arena night session on Tuesday as he begins his campaign to win his home Grand Slam tournament.

Katie Boulter made history at the Australian Open by securing a British record for the most first-round singles victories at the tournament, overcoming Canadian world No. 98 Rebecca Marino in a tense and thrilling match.
