Jannik Sinner has made an empathic start to his reign atop the ATP Rankings – and the Italian currently holds an incredible record for players in the top spot.

The 23-year-old currently holds the highest win percentage in matches played while being the world No 1 in ATP history, dating back to when the rankings were first introduced in 1973.

Here, we look at the top seven men in that statistic – with Sinner currently ahead of tennis icons.

7) Novak Djokovic – 86.1%

Djokovic has spent more time at No 1 in history, with a staggering 428 weeks atop the ATP Rankings to his name.

But, despite the sheer volume of matches he has faced while on the top spot, his win percentage as the No 1 still ranks him as high as seventh among the 29 men to hold that ranking.

Djokovic has an impressive 485-78 record as the world No 1, with a win percentage of 86.1%

6) John McEnroe – 86.9%

5) Roger Federer – 88.5%

With 310 weeks as the world No 1 to his name, only Djokovic has spent more time atop the ATP Rankings than 20-time Grand Slam champion Federer.

2) Bjorn Borg – 91.9%

One of the biggest stars in tennis history, Borg was the ATP’s dominant force during the late 1970s and early 1980s.

Across his career, the Swede won 11 major titles and spent 109 weeks as the world No 1 before his sudden retirement aged 26.

Borg amassed a staggering 136-12 record during his time at the top of the ATP Rankings, a win percentage of 91.9% that has stood the test of time.

1) Jannik Sinner – 94%

Though his win rate may fall over time, Sinner’s stunning start to life as the world No 1 currently ranks him first among the 29 men to hold that ranking.

The Italian has played 50 matches since his rise to the top in June 2024 and has tasted just three times, holding a 47-3 record.

That gives Sinner a win percentage of 94% while ranked as the world No 1, placing him ahead of legends of the sport as things stand.
