After a singles loss and social media drama earlier in the week, Coco Gauff did all her talking on court Wednesday in the United Cup quarterfinals. Gauff won twice — once in singles and then a clinching victory in mixed doubles — to send the Americans into the semifinals in Sydney on Saturday. Gauff beat Maria Sakkari 6-3, 6-2 to give the defending champion United States a 1-0 lead over Greece.
