Serena Williams became the latest high-profile player to pull out of the Miami Open on Sunday, saying she was withdrawing in order to concentrate on her recovery from recent oral surgery. The 23-time Grand Slam champion joins Roger Federer, Rafael Nadal and Novak Djokovic among the stars to have pulled out of the event, which was cancelled last year due to Covid-19. "I am disappointed to withdraw from the Miami Open because of recent oral surgery," Williams said in a statement quoted by US media. "Miami is a special tournament for me because it's my home and I am sad I won't be able to see the incredible fans this year, but I look forward to coming back soon," the former world number one said. rcw/jc
