The clay season on the Hologic WTA Tour began last week, featuring two long-standing tournaments: the Credit One Charleston Open, held since 1973, and the Copa Colsanitas Zurich in Bogota, which started in 1998.
For the second year in a row, both events saw local champions triumph. Jessica Pegula, who had reached the semifinals in Charleston for the past two years, secured her eighth career title and her first on clay as the top seed. This victory marks Pegula`s achievement of winning titles on all three court surfaces: hard, grass, and clay.
Pegula has moved up one position to No. 3 in the newest PIF WTA Rankings, equaling her highest career ranking and regaining the position of American No. 1 from Coco Gauff. She previously held the No. 3 spot in October 2022 and again in September 2023 after reaching the US Open final.
Osorio Achieves Bogota Three-Peat
Camila Osorio, Colombia`s highest-ranked player, successfully defended her title in Bogota, winning her third title at this event. The 23-year-old has climbed one place to No. 53 in the rankings.
Kenin and Kawa Highlight Resurgence of Finalists
Unseeded finalists at both tournaments made significant gains in the rankings. Sofia Kenin reached her 10th career final, her first on clay since Roland Garros 2020, where she was defeated by Pegula in an all-American final, the third of the year. After falling to No. 168 last September, Kenin continues her comeback, jumping 10 spots from No. 44 to No. 34, her highest ranking since the end of 2023.
Katarzyna Kawa of Poland reached her second career final, six years after her WTA main-draw debut in Jurmala. The 32-year-old`s week in Bogota was a test of stamina. She spent 7 hours and 10 minutes just in qualifying, saved a match point in the second round, and upset top seed Marie Bouzkova on her way to the final. Kawa has leaped 67 places from No. 223 to No. 156.
Teenagers Pareja, Kovackova, and Tagger Make Strides
A generational milestone was reached last week when 16-year-old Julieta Pareja became the first player born in 2009 to compete in a WTA main draw after qualifying for Bogota. The American teenager (with Colombian heritage) continued her success by reaching the semifinals, with her strong forehand being a key weapon. As a result, Pareja has jumped 215 places from No. 550 to No. 335.
Pareja`s potential was previously seen when, as a 15-year-old qualifying wild card at the US Open last year, she reached the final qualifying round. Bogota was only the 10th professional tournament of her career, and she is currently the highest-ranked player born in 2009, ahead of Hannah Klugman (No. 559) and Maaya Rajeshwaran Revathi (No. 655).
The leading player born in 2010 is also climbing the ranks. Junior No. 11 Jana Kovackova is currently the youngest player with a WTA ranking. In just her fourth professional event, the 14-year-old Czech player won the Antalya ITF W35 title two weeks ago, becoming the first player born in 2010 to win a professional trophy. She has surged 356 places from No. 1,061 to No. 705 this week. Kovackova`s older sister, 16-year-old Alena, is also a promising talent, ranked No. 13 in juniors and No. 820 in the WTA rankings.
Another teenage talent, 17-year-old Lilli Tagger, achieved her best career result. The Austrian player, known for her one-handed backhand, won her first ITF W35 title two weeks ago as a qualifier in Terrassa, and has jumped 178 places from No. 744 to a new career high of No. 566.
