Emma Raducanu said it was ‘amazing to share the court’ with Serena Williams after defeating her 6-4, 6-0 in the Western & Southern Open first round in Cincinnati. ‘It wasn’t easy, you’re kind of on edge the whole time’ said Raducanu in an interview after the match. The 23-time grand-slam champion recently announced her intention to retire from tennis later this year, in all likelihood after the upcoming US Open.
