Tennis fans in Sydney were treated to an electrifying display of skill and determination as Australia's beloved Alex de Minaur led his nation into the United Cup quarter-finals with a spectacular performance that had the home crowd on their feet.

De Minaur, affectionately nicknamed "Demon" by his loyal fans, demonstrated why he's ranked sixth in the world with a commanding 6-4, 6-1 victory over 18th-ranked rising star Jakub Mensik. The win was even more impressive given that De Minaur had faced disappointment in his opening match, showing the mental fortitude that has become his trademark throughout his career.

"Something I've done really well in my career is bouncing back, so I'm happy I bounced back today," said a pleased De Minaur after his singles victory. His ability to regroup and refocus serves as an inspiration to athletes everywhere about the importance of resilience.

But the Australian star wasn't finished yet. In a thrilling finale, De Minaur teamed up with Storm Hunter for the decisive mixed doubles rubber, where the pair delivered another straight-sets victory to seal Australia's progression to the quarter-finals. The energy in the Sydney arena was palpable as the home crowd celebrated their team's advancement.

The United Cup, which features 18 teams competing in this prestigious ATP-WTA season-opening event, has proven to be an exciting showcase for both established champions and emerging talent. Belgium and the Czech Republic also secured their places in the last eight, with the Czechs advancing despite their 2-1 loss to Australia—a testament to the competitive format that keeps every match meaningful.

In Perth, fans witnessed another display of world-class tennis as Italy's Jasmine Paolini, ranked third in the world and a two-time Grand Slam finalist, secured her first win of 2026 with a 6-2, 6-3 victory over France's Leolia Jeanjean. Paolini's positive attitude shone through despite Italy's exit from the competition.

"First matches are always tricky. I'm happy how I felt on court today," Paolini reflected. "We could not win the group this year but we did our best and fought to the last ball." Her gracious perspective exemplifies the sportsmanship that makes tennis such a beloved sport worldwide.

The tournament continues to build excitement as the quarter-finals approach. Wednesday's matches promise more thrilling action, including defending champions the United States taking on Greece, and Switzerland facing Argentina in Perth. Tennis enthusiasts in Sydney will be treated to world number two Iga Swiatek leading Poland against the Netherlands.

For Australian fans, De Minaur's resurgence couldn't come at a better time, with the Australian Open set to begin later this month. His performance has given home supporters every reason to be optimistic about the nation's prospects at their home Grand Slam.

The United Cup continues to prove itself as the perfect way to launch the tennis season, bringing together the world's best players in a team format that creates unforgettable moments of national pride and sporting excellence.
