The clay season on the Hologic WTA Tour began last week with two long-standing tournaments: the Charleston Open, held since 1973, and the Copa Colsanitas Zurich in Bogota, established in 1998.
For the second year in a row, both events crowned local champions. Jessica Pegula, after reaching the Charleston semifinals for the past two years, secured her eighth career title and first on clay as the top seed. This victory marks Pegula`s success on all three court surfaces: hard, grass, and clay.
Pegula has moved up to No. 3 in the PIF WTA Rankings, equaling her career-high and regaining the position of American No. 1 from Coco Gauff. She previously held the No. 3 rank 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 Bogota title, securing her third victory at this tournament. The 23-year-old has risen one place to No. 53.
Kenin and Kawa Highlight Resurgent Finalists
Unseeded finalists at both tournaments made significant strides 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. Kenin, who had fallen as low as No. 168 last September, 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. Her week in Bogota was demanding, requiring 7 hours and 10 minutes to qualify, saving a match point in the second round, and upsetting top seed Marie Bouzkova on her way to the final. Kawa has climbed 67 places from No. 223 to No. 156.
Teenage Talents Pareja, Kovackova, and Tagger Advance
A generational milestone was reached as 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, advanced to the semifinals, showcasing her strong forehand. Pareja has surged 215 places from No. 550 to No. 335.
Pareja previously showed promise as a 15-year-old wild card qualifier at last year`s US Open, reaching the final qualifying round. Bogota was only her 10th professional event, and she is currently the highest-ranked 2009-born player, ahead of Hannah Klugman (No. 559) and Maaya Rajeshwaran Revathi (No. 655).
The leading 2010-born player, Jana Kovackova, is also making progress. Junior No. 11 Kovackova is the youngest player with a WTA ranking, and recently won the Antalya ITF W35 title in her fourth professional event. She is the first 2010-born player to win a pro title, jumping 356 places from No. 1,061 to No. 705 this week. Her older sister, 16-year-old Alena Kovackova, is also a promising player, ranked No. 13 in juniors and No. 820 in WTA rankings.
Another teenager, 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 as a qualifier in Terrassa, climbing 178 places from No. 744 to a career-high of No. 566.
