Former World No. 2 Paula Badosa withdrew from the U.S. Open on Friday due to a recurring back injury. Badosa, currently ranked No. 12, hasn't played since losing to Britain's Katie Boulter in the first round at Wimbledon on June 30. The U.S. Tennis Association said that Switzerland's Jil Teichmann will replace Badosa in the field. France's Alize Cornet is next in line if someone should pull out. Badosa, 27, reached the quarterfinals of the U.S. Open last year, her top showing at the grand slam event in New York. "It is with a heavy heart that I am announcing my withdrawal from this year's U.S. Open," Badosa said on social media. "This decision was incredibly difficult to make. After the amazing run I had in New York last year and the deep connection I felt with the city and the fans, stepping away from this tournament is very emotional for me. "The U.S. Open has always meant a great deal to me and I have created some of my most special memories there." The Spaniard had her best grand slam performance in January when she reached the semifinals of the Australian Open. Her career-best No. 2 ranking was achieved in the spring of 2022. The U.S. Open tournament starts Aug. 24, with the women's final set for Sept. 6.
