ANKARA: Spanish tennis superstar Rafael Nadal, who won 22 Grand Slam titles, said Thursday that he will retire at the end of this season. "I am here to let you know I am retiring from professional tennis," Nadal, 38, said in a video on Instagram. "The reality is that it has been some difficult years, the last two especially. I don't think I have been able to play without limitations. I think it's the appropriate time to put an end to a career that has been long and much more successful than I could ever have imagined," he said. Nadal added that he will make his final appearance in November's Davis Cup finals in Spain's Malaga. The experienced tennis player suffered from a hip injury during most of 2023, and previously said that 2024 would be his final season. Called the 'King of Clay,' Nadal won a record 14 French Open (Roland Garros) titles, the last in 2022. In addition, he won the Australian Open and Wimbledon titles twice each, and secured four US Open championships. Source: Anadolu Agency
