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

The top seed in the $10 million tournament that began with 18 nations in contention clinched the trophy when Fritz defeated Hubert Hurkacz 6-4, 5-7, 7-6 (7-4) after Gauff outclassed Iga Swiatek 6-4, 6-4 in Sydney.

The Americans also won the 2023 title in the inaugural edition of the tournament, which serves as a tuneup for the Australian Open.

With the second singles contest locked at one set apiece, Fritz raised his level at 3-3 in the tiebreak of the decider to see off Hurkacz and spark a huge celebration.

“Congratulations to Poland on a great week,” said Fritz, addressing a dejected Polish side that finished runner-up at the tournament for a second successive year.

“They’re an incredibly tough team and the margins were very small. I feel that it could have gone either way.

“I want to thank my team, unbelievable support. The vibes all week were amazing. That’s one of the things that makes our team so great and one of the reasons why we’ve been able to do so well.

“We’ve just really come together. It’s amazing.”

Gauff stepped up her preparation for the year’s first Grand Slam, which begins Sunday, with her second straight win over world No. 2 Swiatek in a blockbuster showdown that gave fans at Ken Rosewall Arena their money’s worth.

The world No. 3, who beat Swiatek en route to the WTA Finals title last season, squandered a 2-0 lead in the first set but battled back to gain the upper hand as her opponent committed 19 unforced errors.

In another high-octane set that followed, Gauff recovered a break to level at 4-4 and went on to secure a win that ensured she ended her singles campaign at the tournament unbeaten.

“I have the belief that I’m one of the best players in the world. When I play good tennis, I’m hard to beat,” said Gauff, who also beat Leylah Fernandez, Donna Vekic, Zhang Shuai and Karolina Muchova in the event.

“Today I think I played some great tennis. I’m glad I was able to get a point for Team USA. It was tough today, I’m not going to lie.”
