Each time Jannik Sinner steps onto the court, records seem to tumble. The 23-year-old world number one claimed his third Grand Slam title by defeating Alexander Zverev in the 2025 Australian Open final. This victory solidified his status as one of tennis’s most formidable players.
Former Wimbledon champion Pat Cash declared on BBC Radio 5 Live:
“Sinner, if he’s not already, is going to be one of the greatest players we have ever seen.”
A Year That Transformed Sinner’s Career
Sinner’s dominance began in October 2023 during the China Open, where he famously battled illness mid-match but emerged victorious. This marked the start of an incredible journey:
- Record Since October 2023: 98 wins and just nine losses.
- World Number One: Sinner replaced Novak Djokovic in June 2024, winning 47 of his first 50 matches as the top-ranked player.
- Grand Slam Dominance: A 30-2 record at majors since his first Australian Open win in 2024.
Sinner’s consistency has drawn comparisons to legends like Roger Federer and Rafael Nadal. As Pat Cash noted:
“It’s currently a two-horse race for Grand Slams between Sinner and Carlos Alcaraz.”
Sinner’s Evolution On and Off the Court

Sinner’s co-coaches, Simone Vagnozzi and Darren Cahill, attribute much of his success to his maturity and adaptability. Cahill, who previously coached Andre Agassi and Andy Murray, praised Sinner’s wisdom:
“He’s just 23, but sometimes it feels like he’s much older and wiser than we are.”
Key Improvements in Sinner’s Game
- Improved Serve:
- 563 aces in 2024, a 50% increase from 2022.
- Led the ATP Tour in second-serve points won (57.9%).
- Clutch Resilience:
- Saved 73.7% of break points in 2024.
- Won 75% of tie-breaks.
- Physical and Mental Strength:
- Exceptional movement for his 6ft 3in frame.
- A pre-match routine centered on rest, including 10-hour sleep sessions before key matches.
A Storm on the Horizon: Sinner’s Doping Case
Despite his dominance, Sinner faces uncertainty regarding his future due to a doping case. After testing positive for clostebol in March 2024, he was cleared by an independent tribunal. However, the World Anti-Doping Agency (WADA) has appealed, seeking a 1-2 year ban.
The Court of Arbitration for Sport (CAS) hearing is scheduled for April, just weeks before the French Open. Despite this, Sinner has shown remarkable composure under pressure.
His coach, Vagnozzi, said:
“I think Jannik likes this situation, the pressure point, to be in a storm. In this moment, he plays his best tennis.”
A Player for the Ages
Sinner’s unmatched streak of 10 straight-set wins against top-10 opponents and his rapid ascent in the tennis world are redefining expectations for the sport’s future.
Former British player Annabel Croft praised his ability to focus:
“You have to admire how he puts it all to one side and focuses on one point, one day at a time.”
