A dominant United States lifted their second United Cup mixed team tournament title in three years after they beat Poland 2-0 on Sunday with Coco Gauff and Taylor Fritz both winning their singles matches.

Coco Gauff overcame second-ranked Iga Swiatek 6-4, 6-4 in the opening singles of the United Cup mixed teams tennis event and the United States went on to win the final by beating Poland 2-0.

Coco Gauff says she is feeling great and plans to play "confident tennis" in a United Cup showdown versus Iga Swiatek. On Saturday, the top-ranked American female tennis player impressively handled the business against Karolina Muchova, dismantling the Czech 6-1 6-4 to help the United States reach the final in Sydney.

Coco Gauff led the United States to its second United Cup title with a statement 6-4, 6-4 win over world No. 2 Iga Świątek a week before the start of the Australian Open.

Coco Gauff has just clinched back-to-back wins over Iga Swiatek for the first time in her career after beating the world No. 2 6-4 6-4 in the opening match of the United States and Poland final at the United Cup.

"I couldn’t get my serve in the court my first serve suffered because I was hitting myself because I was trying to get my first serve in the court because I didn’t want to hit a second serve,” said a dejected Coco Gauff last season after losing against World No.
