Australian Open has reached its business end with defending champion Jannik Sinner taking on Alexander Zverev in a battle of ATP’s top-two at the Rod Laver Arena on Sunday. Here’s why both players will be competing under a cloud in the summit clash.

World No. 1 Jannik Sinner fought through blistering heat and an undisclosed ailment to defeat Holger Rune 6-3, 3-6, 6-3, 6-2 and advance to the quarterfinals of the Australian Open on Monday. Sinner, the defending champion, met with the tournament doctor before beginning the match and needed a medical timeout in the third set.

Novak Djokovic was at the centre of another Australian Open row on Monday while Jannik Sinner needed medical attention in fierce heat to battle into the quarter-finals and Iga Swiatek won easily. But American teenage qualifier Learner Tien’s fairytale run is over after he suffered a thigh problem in a four-set defeat to Italy’s Lorenzo Sonego in Melbourne.

Jannik Sinner has become the center of much debate following his brilliant run at the Australian Open. The Italian tennis phenom, fresh off his title defense in Melbourne, grabbed attention not only for his on-court success but also for rejecting an invitation to visit the Quirinale presented by Italian President Sergio Mattarella.

Among them: the Italian has now won his last 10 matches in a row against Top 10 players in straight sets, the first man to do that since ATP rankings began in 1973.

The South Tyrolean star embraced a 73-6 score in 2024, lifting eight ATP trophies and leaving everyone behind. Jannik was the top favorite at this year's Australian Open. World no. 1 survived a scare against Holger Rune and defended the title in style!

Jannik Sinner continues to break new records and the dream of achieving the 'Calendar Grand Slam' may not be a utopia for this player. The world number 1 is increasingly confident in his means and has further improved his game, becoming almost unstoppable on the hard courts where he has won the last three Grand Slam tournaments played.
