Coco Gauff and Taylor Fritz have powered the U.S. into the semifinals of the United Cup mixed teams tennis event.

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.

"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.

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.
