Team USA's Coco Gauff will play her first match of 2026 against Argentina's Solana Sierra, who won her opener. Comeback Player of the Year Belinda Bencic will meet France's Leolia Jeanjean. Maya Joint and Elise Mertens are also in action as play gets underway in Sydney.

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.

Asked who she enjoyed watching, Gauff named three Grand Slam champions on the ATP Tour. “I mean, Jannik [Sinner] and Carlos [Alcaraz] are pretty fun to watch. I like watching Daniil [Medvedev] just because you never know what he'll do on the court,” Gauff added.

Coco Gauff bounced back from her singles defeat by partnering with Christian Harrison for the clinching mixed-doubles win as the United States eliminated Spain from the United Cup.

Coco Gauff reveals she likes to tune into Daniil Medvedev's matches for one simple reason, and that's never knowing what the Russian will do on the court. On Friday, the United States team held its pre-tournament press conference at the United Cup.

Coco Gauff caused a stir when she suggested American tennis fans were the 'worst' for supporting their players.
