Serena Williams will be fit to defend her US Open title after recovering from the virus which ended her Wimbledon.
The world number one, 32, was forced to pull out of her doubles match with sister Venus earlier this month after struggling to serve.
But she makes her return at the Bank of the West Classic at Stanford University on Wednesday and will be ready for the US Open when it starts on 25 August.
She said: “I feel very good. I feel very happy to be here, so it’s good.”
Williams was beaten in the third round of the singles at Wimbledon by France’s Alize Cornet, before retiring from the doubles a few days later.
