Two-time defending champion Jannik Sinner knows his way around Rod Laver Arena—but after two wins in Melbourne, his latest Australian Open look is proving far more divisive than his tennis. The world No.

Two-time defending champion Jannik Sinner's title defense at the Australian Open 2026 has progressed without a hitch so far.

At the 2025 US Open, Sinner was soundly beaten by Alcaraz. Since then, the two-time Australian Open champ has made adjustments.

Jannik Sinner lived up to the prediction and reached the third round at the Australian Open without any problems. The world No.2 – who had played just two sets against Hugo Gaston on his debut – left very little room for local idol James Duckworth on the iconic Rod Laver Arena, showing excellent condition both technically and physically.

Jannik Sinner is getting attention over who isn't supporting him at the Australian Open yet.

Jannik Sinner is on track for a third straight Australian Open title after a clinical 6-1, 6-4, 6-2 victory over James Duckworth. The world number two was flawless, setting up a third-round clash with American Eliot Spizzirri.

Jannik Sinner has won 16 straight matches in Melbourne

Novak Djokovic rolled back the years to reach the Australian Open third round but Jannik Sinner, the man who has usurped him as king of Melbourne Park, showed why he is favourite to claim a hat-trick of titles.

Meanwhile, Stan Wawrinka extended his final Australian Open campaign with a gutsy victory over Arthur Gea. Taylor Fritz also booked his spot in round three, with the American defeating Vit Kopriva

Jannik Sinner kicked off his Australian Open defence by spending just 68 minutes on the court after first-round opponent Hugo Gaston retired while trailing 6-2 6-1.

If the 24-year-old really improves not only in this aspect, but also in other parts of the game, he could become an insoluble enigma for his opponents.
