There are a lot of notable shifts in the rankings this week after a big week of play in Canada—a Masters 1000 event for the men in Toronto, a WTA 1000 event for the women in Montreal—but maybe the most notable feat comes from a player who doesn’t move at all this week.

After reaching her ninth semifinal of the year in Montreal, Iga Swiatek spends her 72nd week at No. 1 this week, surpassing Caroline Wozniacki for 10th-most weeks at No. 1 in WTA rankings history.

377: Steffi Graf
332: Martina Navratilova
319: Serena Williams
260: Chris Evert
209: Martina Hingis
178: Monica Seles
121: Ashleigh Barty
117: Justine Henin
98: Lindsay Davenport
72: Iga Swiatek
71: Caroline Wozniacki

Swiatek is guaranteed to keep No. 1 for at least another three weeks, as she’s currently out of the reach of No. 2 Aryna Sabalenka—but the top ranking could change hands after the US Open, depending on how the two players (and others) do in Flushing Meadows this year.

Also on the WTA rankings, Liudmila Samsonova jumps from No. 18 back to her career-high of No. 12 after reaching her first WTA 1000 final in Montreal, and American Alycia Parks rises from No. 47 to No. 40—her Top 40 debut—after reaching the second round in Canada.

On this day a year ago, Rune was ranked No. 26. On this day two years ago, he was ranked No. 191.

Meanwhile, over on the ATP rankings, there’s a major breakthrough: Holger Rune moves up from No. 6 to No. 5, his Top 5 debut.

The 20-year-old Dane is just the second man born in 2000 or later to reach the Top 5, and the fifth player born in 2000 or later, male or female, to reach the Top 5 on either the ATP or WTA rankings.

~ Holger Rune [born in 2003, Top 5 debut in August 2023]

Speaking of players born in the 2000s breaking into the Top 5, 2001-born Jannik Sinner nearly did that today too, rising from No. 8 to a new career-high of No. 6 after winning his first Masters 1000 title in Toronto. He’s just 65 ranking points behind Rune now (4,790 to 4,725).

Sinner is now tied with Matteo Berrettini, who has also gone as high as No. 6, for second-highest-ranked Italian in ATP rankings history, after Adriano Panatta, who reached a career-high of No. 4 in 1976.

Alex de Minaur, who made his first Masters 1000 quarterfinal, semifinal and final in Toronto before finishing runner-up to Sinner, rises from No. 18 to No. 12 today, surpassing his previous personal best of No. 15.

And shout out to Aleksandar Vukic, who rises from No. 62 to No. 48 today—his Top 50 debut—after reaching the third round in Toronto. The 27-year-old Australian only just made his Top 100 debut on May 22nd, and now, less than three months later, he’s in the Top 50.
