Jannik Sinner has added another achievement to his impressive resumé. He has defended his first Grand Slam title by winning the Australian Open for a second successive year, in a tournament dominated by HEAD players.

In Sunday’s final in Melbourne, the 23-year-old Italian beat his fellow HEAD tennis ambassador Alexander Zverev to claim his 19^th career singles title and his third major. He is now unbeaten at hard-court Grand Slam tournaments since losing to Zverev in five sets in the fourth round of the 2023 US Open.

Sinner was a little under-the-weather in his fourth-round match against Holger Rune, on a day in which temperatures in Melbourne reached the mid-30s Celsius. But he was superb two days later in beating Alex De Minaur in the quarter-finals, and then dismissed Ben Shelton in the semis before winning the all-HEAD final.

“Triumphing in Melbourne confirms Jannik as the leading player in today’s tennis,” said Ottmar Barbian, executive vice-president of HEAD’s racquet sports division. “But as well as leading the sport, he leads one of the most successful groups of HEAD players in the history of our brand. Many of our ambassadors did well at the Australian Open, notably Novak Djokovic, Sascha Zverev, and Coco Gauff, and others have done well in recent months, such as the US Open runner-up Taylor Fritz and the Wimbledon champion Barbora Krejcikova. It is immensely satisfying to see the work we have put into making the finest frames become associated with the very best in the sport.”

Sinner’s win was a popular one among the home fans, given that he has been coached since early 2023 by the former Australian player Darren Cahill. During the tournament, Sinner said 2025 was likely to be the last year he and Cahill will work together, as Cahill plans to retire at the end of the year. “I feel very, very lucky and happy to be his last player on tour,” Sinner said of Cahill after his second-round match. “He has been an amazing, amazing coach and person, not only for me but for all the other players he has worked with.”

Sinner, who comes from San Candido in the German-speaking area of northern Italy and spoke German at home during his childhood, was a proficient skier from the ages of 8 to 12. Having chosen to specialise in tennis, he won the ATP NextGen title in 2019, and has now won three majors, four Masters-1000 tournaments, the ATP Finals, and two Davis Cups for Italy.
