Coco Gauff and Taylor Fritz might be the best Team USA tennis duo since the Bryan Brothers and the Williams Sisters. The top-ranked Americans on the ATP and WTA Tours, Gauff and Fritz, lead Team USA in the 2026 United Cup set to begin January 2 in Perth and Sydney, Australia.
The United States won the 2023 and 2025 United Cup titles. Germany, led by Alexander Zverev and Laura Siegemund, won the championship in 2024.
Defending an international title is tough in any sport. However, Gauff and Fritz are the dynamic duo with the right mix of offense and defense, temperament, and big-match experience to defend Team USA’s title.
Why The United Cup Format Favors Team USA
The United Cup format features 18 teams divided into three groups. Each group session consists of three matches: one men’s singles match, one women’s singles match, and one mixed doubles match. Both singles matches will feature the team’s No. 1-ranked singles player, and that’s why this United Cup format favors Team USA.
Team USA has the highest combined rank of men’s and women’s singles players in the field. Poland’s Iga Swiatek is the only female player in the United Cup draw ranked higher than Gauff. Canada’s Felix Auger-Aliassime is ranked No 5, a spot above Fritz. However, Canada’s top-ranked female, Victoria Mboko, is ranked No. 18.

Not that Gauff and Fritz won’t face other tough opponents. Jasmine Paolini and Flavio Cabolli, ranked No. 8 and No. 22, are playing for Italy. Despite recent struggles, Greece’s Stefanos Tsitsipas and Maria Sakkari are also a difficult duo.
However, Gauff and Fritz bring the most combined star power, hard-court prowess and mixed doubles experience. Fritz has been a Top 10 player the past four years, and Gauff is again the highest-paid female athlete in the world, winning on and off the court.
These two have a great chance of winning their singles matches, and if one loses, they are solid in mixed doubles. A team only needs to win two matches per session.
Team USA has Mackenzie McDonald, a solid singles player, and Christian Harrison, a Top Ten doubles player, to back up Fritz. Varvara Lepchenko and doubles specialist Nicole Melichar-Martinez could pair with Fritz if Gauff is exhausted. But Guaff rarely gets tired.
Why Coco Gauff Is The Ultimate Team Player
The saying that good defense wins championships usually applies to football and basketball teams. However, Gauff’s defense keeps Team USA in points and matches.
Gauff’s court IQ and ability to construct points are top-notch. Her athleticism allows her to chase down would-be winners, which is one reason Gauff is difficult for opponents. She’s relentless, frustrates big hitters and is one of the best returners in the game. In 2025, she won 48.8 % of her return games.
However, she led the WTA in doubles faults. This is where Fritz’s strength makes up for her weakness. When Gauff gets in trouble on a second serve, Fritz can end the point at the net.
Gauff is also positive on the court. Although seven years younger than Fritz, Gauff displays on-court maturity beyond her age. She can keep Fritz from fizzling late in matches.
Last year, Gauff’s United Cup performance followed a WTA Final title in late 2024, boosting her confidence before the 2025 Australian Open.
Taylor Fritz Looking To Win His Third United Cup
Fritz could help Team USA win a third United Cup. Fritz led the team of Frances Tiafoe, Madison Keys, and Jessica Pegula that captured the title in 2023. During that run, Fritz played doubles with Pegula.
The common denominator in Team USA’s dominance in United Cup play, Fritz is a proven hard-court winner. He’s reached the quarterfinals at the Australian Open, the final of the 2024 U.S. Open, and played a pivotal role in Team World’s win over Europe at the 2025 Laver Cup, where he stunned Carlos Alcaraz and upset Alexander Zverev.
Fritz reached a career high No. 4 in 2024, after losing to Jannik Sinner in the final of the U.S. Open. He also reached the 2024 ATP Final, where he lost to Sinner. Sinner and Alcaraz aren’t playing in the United Cup. Fritz has a 3-1 record against Auger-Aliassime. His biggest threats are Tsitsipas (2-3) and Norway’s Casper Ruud (1-3).
Why Coco Gauff And Taylor Fritz Work Well Together
In 2024, Gauff and Fritz led Team USA at the Summer Olympics. They reached the quarterfinals, where they lost to Canadians Auger-Aliassime and Gabriela Dabrowski, who won the Bronze medal. But that was on clay, not Fritz’s best surface.
Besides having playing styles that complement each other, Gauff and Fritz respect one another.
“Don’t doubt Taylor Fritz,” Gauff said in a post-final press conference after winning the 2025 United Cup.
“It was great. We played the majority, almost every single match except for one, Coco played first so always put me up 1-0, so I felt like it put so much pressure on me, because I didn’t want to be the one to lose it for the team because she already won,” said Fritz.
The pressure will be on Gauff and Fritz to bring home another title for Team USA. These two Americans are the dynamic duo to get it done.
