Two first-time winners and the World No.1 captured singles titles last week.

Iga Swiatek captured her fourth title of the 2023 season and extended her lead atop the Hologic WTA Tour Rankings. She now holds a 645-point advantage over No.2 Aryna Sabalenka. This week marks the 70th week at No.1 for Swiatek, who has held the top ranking since April 4, 2022.

One week after making her Top 60 breakthrough, Aranxta Rus becomes the oldest player in tour history -- at 32 years old -- to win her first WTA singles title. With the title run in Hamburg, Rus reaches a career-high ranking of No.42, up 18 spots from last week. She becomes the first Dutchwoman to move into the Top 50 since Kiki Bertens held the No.25 spot the week of Aug. 9, 2021.

This week's results

Elisabetta Cocciaretto won her first career singles title, in Lausanne, paving the way for the Italian to make her Top 30 debut this week. She moves ups 12 spots, from No.42 to No.30. At 22 years, 187 days old, she becomes the youngest Italian to make her Top 30 debut in 22 years when a 21-year-old Francesca Schiavone reached the Top 30 on Nov. 5, 2001.
