As the 2025 Canadian Open approaches, players face significant ranking point changes influenced by their performances at this event and the 2024 Washington Open. The Canadian Open, a key WTA 1000 event in the North American hard-court season, runs from July 27 to August 7, stretched over 12 days for the first time.

Jessica Pegula, the defending champion, has the highest points at stake with 1,000 points to defend from her 2024 victory in Canada. She did not compete in the Washington Open last year, so her points drop there is zero. Amanda Anisimova, the 2024 runner-up in Canada, will lose a total of 783 points—650 from Canada and 133 from reaching the Washington quarter-finals.

World No. 1 Aryna Sabalenka, absent from both the Washington Open and the Canadian Open this year, will lose 410 points earned from last year’s semi-final and quarter-final results in Washington and Canada respectively. Sabalenka chose to rest after Wimbledon and currently holds a solid lead in the rankings, with 12,420 points before the Canadian Open.

Coco Gauff, ranked second globally and reigning French Open champion, will drop 120 points, having reached the third round in last year’s Canadian Open but not playing in Washington. Wimbledon champion Iga Swiatek holds no points to defend at either event, having not played in either during 2024.

Other notable players including Mirra Andreeva, Jasmine Paolini, and Elena Rybakina did not participate in either Washington or Canada last year, meaning they face no points losses here.

Emma Raducanu, excluded from last year’s Canadian Open due to ranking, will not lose points there but will see her 108 points from a 2024 Washington quarter-final expire. Raducanu’s stronger performance this year, reaching the Washington semi-final, will add 195 points after the Canadian tournament.

The unique scheduling this year, following a 2024 calendar impacted by the Paris Olympics, requires players to drop points from two tournaments. This complex ranking update will take place following the Canadian Open, affecting player seedings and rankings ahead of the US Open.

The Canadian Open, a prestigious Masters 1000 event on the ATP Tour, has seen many tennis legends perform at their best. Here, we spotlight the seven men who hold the highest win percentages at the Canadian Open in the Open Era, considering players with at least 10 matches played.

Boris Becker, a former world No 1, impressed with an 81.82% win rate based on a 9-2 record. Becker claimed the Canadian Open title on his debut in 1986, defeating Stefan Edberg in the final. He also reached the semifinals in 1987 and participated again in 1993.

Björn Borg was a dominant figure in the late 1970s. He secured the Canadian Open title in 1979 after defeating John McEnroe and reached the final in 1980 but retired injured against Ivan Lendl. Borg ended with an 82.61% win rate, holding a 19-4 match record at the tournament.

Rafael Nadal matches Borg’s 82.61% win percentage, the fifth highest in the Open Era. Nadal has claimed the Canadian Open five times: in 2005, 2008, 2013, 2018, and 2019. His 38-8 win-loss record highlights the event as his most successful hard-court tournament.

Novak Djokovic boasts a 84.09% win rate with a 37-7 record. The Serbian won the Canadian Open in 2007, 2011, 2012, and 2016 and finished runner-up to Andy Murray in 2015.

Ilie Năstase, a prominent player in the early Open Era, holds the third-highest win percentage at 84.62%. He won the title in 1972 and reached a second final in 1975, finishing with an 11-2 record.

Guillermo Vilas was a two-time Canadian Open champion in the 1970s, winning in 1974 and 1976. With a 17-3 match record, Vilas holds an 85% win rate.

Leading all others, Ivan Lendl owns the highest win percentage at the Canadian Open, winning six titles (1980, 1981, 1983, and 1987-89) and finishing runner-up in 1982 and 1985. His 57 wins in 66 matches give him an 86.36% winning percentage, underscoring his dominance at this event.

The dominance of Carlos Alcaraz and Jannik Sinner in recent Grand Slam tournaments has raised the question of who might emerge as their future rivals on the ATP Tour. These two multiple-time Grand Slam champions hold the top two spots in the world rankings and have split the last seven Grand Slam titles between them.

Holger Rune, despite a recent plateau, remains a noteworthy contender. At 22, Rune has previously achieved a ranking as high as world No. 4 and secured a Masters 1000 title at the 2022 Paris Indoors. He also claimed the Barcelona Open title in April with a win over Alcaraz and was an Indian Wells finalist this year. With tennis legend Andre Agassi now mentoring him, Rune may still have the potential to mount a serious challenge.

Lloyd Mensik, 19, continues his rapid ascent, highlighted by his March Miami Open victory—his first ATP and Masters 1000 title—which pushed him into the top 25, reaching a career-high of world No. 17. Despite solid performances, Mensik has yet to advance beyond the third round in a Grand Slam, an area he will need to improve to solidify his status among the elite.

Arthur Fils, at 21, has shown significant promise with two ATP 500 titles last year and made history by reaching the quarter-finals of the first three Masters 1000 events of the current season—the youngest to do so since 1990. While an injury at the French Open caused a drop from the top 20, his impressive forehand and confidence make him a player to watch once recovered.

Thiago Seyboth Wild Fonseca, an 18-year-old sensation from Brazil, has already secured an ATP Tour title at the Argentina Open and broke into the top 50 after a strong Wimbledon debut. Known for a powerful forehand and early maturity on the tour, Fonseca is expected to continue his rise in the coming years.

Learner Tien, ranked world No. 67, surprised many with four wins against top-10 players in 2025, including an impressive victory over Daniil Medvedev at the Australian Open. Known for his tactical intelligence rather than sheer power, the 19-year-old American is on the brink of competing with the sport’s best.

Each of these young players exhibits qualities that could eventually see them challenge the current hegemony of Alcaraz and Sinner, though consistency at Grand Slams remains the common milestone yet to be conquered.
