The United Cup announced the first confirmed players for its 2025 edition. The mixed-gender tournament replaced the ATP Cup in 2022 and, like the previous Hopman Cup, features top ATP and WTA players competing for ranking points in preparation for the Australian Open.
This tournament offers a great opportunity to kick off the year competitively, with significant prize money and the chance to earn up to 500 points depending on performance. The champions were the United States in 2023 (4-0 win over Italy) and Germany in 2024 (2-1 win over Poland).
First stars announced for United Cup 2025
There are 18 teams that qualify based on the male and female rankings of their players. The first 6 countries qualify through the ATP ranking of their No. 1 male player, and another 6 countries qualify through the WTA ranking of their No. 1 female player.

The final six countries qualify based on the combined rankings of their No. 1 ATP and WTA representatives. Australia also has a reserved spot as the host nation in case they don’t qualify independently. Each team will consist of three or four players from each Tour.
The first confirmed players for the tournament were the Greeks Maria Sakkari and Stefanos Tsitsipas: “Representing Team Greece in a team competition like that at the beginning of the year allows me to be really patriotic and start the year very strong,” said Tsitsipas.

Zverev/Siegemund won the title for Germany in 2024 by beating Swiatek/Hurkacz in the final.
Additionally, Paris 2024 gold medallist Zheng Qinwen was confirmed to lead China, while Casper Ruud will also compete as Norway’s main player. “I’m delighted to be able to qualify China again for the United Cup,” said Zheng. “The United Cup presents a unique opportunity to play for our country in a mixed-team environment, similar to the Olympics, and we’re excited to share this experience together.”
Tournament Director Stephen Farrow anticipated a great event after announcing the first participants. Speaking about the Greek duo, he said: “Tsitsipas and Sakkari qualified Greece for the first two editions of the United Cup. They are both fan favourites and are looking forward to starting their year with us in 2025.”

He also highlighted the presence of Chinese player Zheng, one of the WTA’s biggest revelations in recent seasons, who participated in the 2024 edition: “Zheng had an incredible 2024. She reached the Australian Open final in January, won gold in Paris, and has maintained her Top 10 ranking throughout the year,” said Farrow. “She’s a great player and a big personality, and we’re thrilled to welcome her back to the United Cup.”

- Vukov is doing this to Lena... AGAIN!!!!! WTA's autonomous collective should be dismantled for allowing Vukov to re-emerge from his hand-slapping suspension. Just ask WTA employees how that's been going lately as they witness his continued verbal abuses. Women's Pro Tennis should start over.
mandoist08-11-2026 - Can't help but suspect Vukov is back to his old self again. Thank you, WTA. Perhaps you can give them a "Battling Couple of the Year Award 2026" ??
mandoist08-11-2026 - Wtf? Why is there no reason? And what about the men's?Bel08-11-2026
- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.
mandoist06-11-2026 - Enough of her bullshit. Go marry someone.
mandoist06-11-2026 - Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
- Having spent weeks and weeks through the years on tour, I can say with confidence that Conchita was (is) one of the very few who realize the surprising level of maturity (and sometimes lack of) which Mirra seems to have developed in such a demanding adult world of Pro-Tennis. While at the same time reminding herself (Conchita, that is) that Mirra is still young and developing mentally and physically. The general public may forget at times, or not at all realize, these modern era young athletes do not have a 'normal' Youth. It's a major sacrifice, among countless sacrifices, these athletes must make. People who blow-off that fact are ignorant and unfair when they blurt out, "They choose fame so they have to put up with the intrusions on their lives". No, they do not.
mandoist05-11-2026 - Okay... someone with a camera was EAVESDROPPING on a private conversation. Shouldn't that be the point of discussion here? Regardless of the sensationalist crap by media, Pegula (and anyone) has a right to an opinion. There used to be an expectation that private conversations were respected, regardless of 'stardom' and whatever other defensive excuses media tries to shove in our faces. Boo-hoo if feelings are hurt. BTW: Having been employed at various tourney venues, etc., I can't tell you how nasty and offensive players can be when discussing their opponents and colleagues... in "private". Well, I could, but won't. I also challenge anyone to deny what Jessica said is false.
mandoist05-11-2026 - Vacherot is Mongasque, rather than Swiss. The tournament was Swiss :DTrwd7702-11-2026
