Rankings Winners & Losers: Andreescu cracks Top 15, Osaka back to top

After a legendary week in Toronto, where she became the first Canadian woman to win the Rogers Cup in 50 years, Bianca Andreescu made a major move up the WTA rankings this week, rising from No. 27 to No. 14. She's not just making her Top 20 debut, but also shattering her previous high of No. 22.

The 19-year-old beat No. 5 Kiki Bertens, No. 3 Karolina Pliskova and No. 10 Serena Williams (via first-set retirement) en route to the title to improve to 7-0 in her career against Top 10 players. Could the Canadian be Top-10 bound herself?

“This has definitely got my confidence level up here,” Andreescu said. “Being able to deal with all the pressure and all the expectations from everyone, I’m just really proud with how I dealt with everything. And hopefully this win can give me momentum going into the US Open.”

Andreescu withdrew from this week’s Western & Southern Open in Cincinnati, but she’ll have a great opportunity to continue her climb in New York: She lost in the first round of qualifying last year.

Naomi Osaka, who reached the quarters in Toronto before falling to Serena, rises from No. 2 to No. 1 this week, taking the top spot back from Ashleigh Barty, who spent the last seven weeks there. This will be Osaka’s 22nd career week at No. 1 as she spent her first 21 weeks at the top earlier this year. It may be a short stint, though since both Barty and Pliskova have a shot at taking it from her in Cincinnati.

There were more WTA players moving up the rankings after strong performances in Toronto. Finalist Serena rose from No. 10 to No. 8, her highest ranking since coming back to the tour as a mom. Sofia Kenin, who scored her first win over a No. 1 against Barty en route to the Toronto semifinals, rose from No. 29 to a new career-high of No. 22. Qualifier Marie Bouzkova soared from No. 91 to a new high of No. 53 after reaching the semifinals; the Czech just broke into the Top 100 three weeks ago.

Roberto Bautista Agut, who has had a breakthrough year at the Grand Slams—he reached his first quarterfinal at the Australian Open and then his first semifinal at Wimbledon—rises from No. 13 to a new career-high of No. 11 after reaching the quarterfinals in Montreal, where he fell to Gael Monfils. The Spaniard first reached No. 13 in October 2016, and nearly three years later, he’s finally bettered it.

After reaching the first ATP Masters 1000 final of his career in Montreal, where he fell to No. 2 Rafael Nadal, Daniil Medvedev inched up from No. 9 to a new career-high ranking of No. 8, trading spots with Karen Khachanov, whom he had beaten in an all-Russian semifinal on Saturday.

And despite losing his opening match this past week, Kei Nishikori moved up from No. 6 to No. 5, marking his first time in the Top 5 since the week of April 17, 2017. The Japanese has been as high as No. 4.

There were a few notable drops this week, too: Grigor Dimitrov, a quarterfinalist in Canada last year, fell from No. 54 to No. 74 after losing first round this year; Robin Haase, also a quarterfinalist in Canada last year, fell from No. 86 to No. 123 after losing in qualifying this year; and two former No. 1s on the women’s side, Venus Williams and Maria Sharapova, both slipped after first-round losses in Toronto this year, the American going from No. 56 to No. 65 and the Russian from No. 81 to No. 97.
