While there were no fans in attendance due to the COVID-19 pandemic, Williams had her Husband Alexis Ohanian and their daughter Olympia as her special cheerleaders in the stands.
According to People, Serena said: ‘I hope she saw her mama fighting. I don’t think she was playing attention between you and me. I think she was playing with some princesses upstairs.’
Serena will compete against Greece’s Maria Sakkari next.
