Top six ATP players with highest winning percentage as World No. 1

Jannik Sinner continues to steal the spotlight on the ATP Tour following his Australian Open 2025 title defence.

Italian star tennis player Jannik Sinner found himself face-to-face with Alexander Zverev in the final of the Australian Open 2025. It was a high-stakes encounter with plenty at stake for both players. Sinner was looking to get ahead of Nicola Pietrangeli for most Grand Slam wins by an Italian. Zverev was looking to etch a German name on the list of winners, the first since Boris Becker in 1996. 

Jannik Sinner won in straight sets in a battle between the world No. 1 and No. 2 players on the ATP Tour. It has been a prolific unbeaten run for Sinner since he won his maiden major in Melbourne a year ago.  

Having won his third major, the Italian has recorded a prolific run since the 2024 season got underway. Sinner matched some of the biggest names in tennis, securing a high percentage of wins as ATP No. 1. The 23-year-old player reached the top spot in the ATP rankings for the first time upon the completion of the 2024 French Open.

Here, we take a look at the top six ATP players with the highest winning percentage as World No. 1.

Jannik Sinner – 47-3 – 94%

Sinner has picked up from where he left off in 2024, extending his domination in what looks like a one-horse race. Alcaraz exited in the last eight to Djokovic. The Serb retired after a set was played in his semi-final against Zverev. At this point, the Australian Open 2025 trophy was all but in the bag for Sinner. He defended his title with a clinical 6-3 7-6 (7-4) 6-3 win over Zverev.

Sinner is now 47-3 since becoming World No. 1, translating into a 94% win rate. The win over Zverev was his tenth such result in a row in straight sets against the ATP top ten. He is in his 34th week as No. 1, two shy of Alcaraz, who has spent 36 weeks as No. 1. 

Bjorn Borg – 136-12 – 91.9%

Swedish legend Bjorn Borg, also known as ‘The Ice Man,’ earned 136 wins for 12 losses during his stint as ATP No. 1. Bjorg has won 89.8% of matches at majors, and his most successful run was at Wimbledon(5). On the grass courts of SW19, he finished with a 51-4 record and a winning percentage of 92.7%. Between 1976 and 1981, Bjorg won on the top of his game and celebrated with an unbeaten 41-win undefeated streak. As World No. 1, he accumulated a 136-12 record, winning 91.9% of matches played. 

While he never lifted the Australian Open trophy, by the time he retired at 26, he had added six French Open titles and another four at the US Open. His rivalry with John McEnroe was most talked about, having crossed paths with the American 14 times in just four years (1978-81). Borg spent a total of 109 weeks as World No. 1.

Jimmy Connors – 408-45 – 90.1%

Jimmy Connors had a love affair with New York, winning five US Open titles between 1974 and 1983. His 40-9 record in New York contributed to his 408 (90.1%) match wins as World No. 1. Connors holds the Open Era record for most titles won (109). He finished four consecutive years between 1974 and 1978 as the top-ranked ATP player. The American spent 160 weeks on the trot after attaining the top ranking in July 1974.

Connors’s main rivals were Bjorn Borg, John McEnroe, and Ivan Lendl. In addition to his five US Open trophies, the American lifted two at Wimbledon and one in Melbourne. Despite his professed love for Paris, Connors would only make the last four at the French Open, with appearances in 1979, 1980, 1984, and 1985.

Ivan Lendl – 362-44 – 89.2%

Ivan Lendl was a bit of a late bloomer in the Open Era, not winning a Grand Slam until 1984, six years after turning pro. That year, he won the French Open with a five-set win over John McEnroe. It was Lendl’s fifth title round appearance, and the Czechoslovakian-born player’s first of eight Grand Slams Lendl would go on to win. The other trophies he won were two more in Paris, three in New York, and two in Melbourne.   

Lendl kept the ATP No. 1 spot for 270 weeks, of which 157 were consecutive. He finished as a year-end No. 1 on four occasions and amassed 94 titles in his 16-year career. He trails Connors in overall win percentage by a whisker with a 362-44 (89.2%) win-loss record as No. 1.

Roger Federer – 430-56 – 88.5%

Roger Federer spent a total of 310 weeks as ATP No. 1, 237 of them consecutively. During his long stretching stint as the World No. 1, he finished with a record of 430-56 (88.5%). His 430 match wins at the top of the ATP rankings are the most by any player in the Open Era. 

The Swiss maestro stamped his authority at Wimbledon, winning eight titles at the hallowed venue and his first in 2003. Federer matched the five-win streak of Bjorn Borg at Wimbledon in 2007 and came close to going one-up on the legendary Swede in 2008. A sixth consecutive Wimbledon title did not materialize as it was Rafael Nadal’s turn to take home the trophy after a thrilling five-set contest in which Federer came back from two sets down to take the match to a decider.

John McEnroe – 226-34 – 86.9%

John McEnroe is seventh on the list of ATP players with the most weeks at No. 1 (170) and ahead of his rival Bjorn Borg. McEnroe spent 58 of those 170 weeks uninterrupted as World No. 1.  McEnroe tasted success at Wimbledon and the US Open. However, success in Paris and Melbourne eluded the Americans. Yet, McEnroe amasses a 226-34 (86.9%) record at Grand Slams. 

It was McEnroe who hastened Björn Borg’s retirement at the age of 25 when he broke his run of five consecutive Wimbledon titles by defeating the Swede in the 1981 Wimbledon final. McEnroe made New Yorkers happy with four US Open titles (1979, 1980, 1981 and 1984). He also picked up three Wimbledon titles (1981, 1983 and 1984).  In 1984, McEnroe flirted with the Coupe des Mousquetaires but saw his hopes dashed by compatriot Ivan Lendl.
