World No. 3 Coco Gauff took down No. 2 Iga Świątek in straight sets at Sunday's United Cup final, helping to secure a big US team win at the Australian Open tune-up tournament.

"It's great to win a team event, the only team event I've ever won, so I'm super excited," Gauff said after the match.

With Sunday's victory, Team USA owns two of the three titles in the annual 18-country contest, adding the 2025 trophy to their inaugural 2023 hardware. Świątek's Poland, on the other hand, fell short for the second year in a row after also earning runner-up status behind 2024 champion Germany.

Gauff doesn't skip a beat in 2025 kickoff

After winning every set in the new year, Gauff remains undefeated in 2025 play, maintaining the momentum she built by closing out her 2024 campaign with victories at both October's China Open and November's WTA Finals.

The 20-year-old faltered in her attempt to defend her 2023 US Open title, falling in the fourth round of the Grand Slam's 2024 edition last September. In the wake of that disappointing result, Gauff parted ways with coach Brad Gilbert, and began tweaking her game to solidify her style — with a particular focus on grip strength.

Behind new coach Matt Daly, the changes to Gauff's grip improved both her serve and her forehand — the latter something Świątek had exploited to consistent success over Gauff, with the Polish star logging 11 wins in the pair's first 12 meetings.

The era of Świątek's dominance over Gauff seems to have ended, however, with the US phenom now adding two straight wins over Świątek to the pair's all-time tally, tacking Sunday's victory on top of their 2024 WTA Finals tilt — a tournament in which Gauff also defeated world No. 1 Aryna Sabalenka.

Her trend of downing top-ranked international tennis stars continued at the United Cup, where Gauff also defeated No. 31 Leylah Fernandez, No. 19 Donna Vekic, and 2024 US Open semifinalist No. 21 Karolina Muchová en route to the US team title.

"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," Gauff added on Sunday.

First 2025 Slam to test Gauff's momentum

Gauff's hot streak will face its first major 2025 challenge when tennis' first Grand Slam of the year, the Australian Open, kicks off on January 12th to run through January 25th.

The Melbourne tournament will see Sabalenka, who opened her 2025 account with an 18th career title at the Brisbane International on Sunday, try to become the first three-peat Australian Open women's champion this century.

However, Gauff is primed to interrupt that feat, with the US star poised to give the back-to-back defending champ a run for her money.

The 2025 Wimbledon Championships wrapped its second round on Thursday, with the grass court Grand Slam seeing just 15 of the tournament's 32 seeded players advance to the Friday and Saturday's third round.

A full half of the WTA's Top 10 players did not survive the week, with 2024 Wimbledon finalist and world No. 5 Jasmine Paolini joining four first-round star exits by falling to unseeded Kamilla Rakhimova in a three-set, second-round battle on Wednesday.

At the same time, unseeded fan favorites like Japan's No. 53 Naomi Osaka and England's own No. 40 Emma Raducanu secured third-round spots at the London Slam, joining top surviving contenders like No. 4 Iga Świątek and defending Wimbledon champion No. 16 Barbora Krejčíková.

Notably, a full five US players managed to move ahead, tied for the largest national contingent still standing at the tournament.

Led by 2025 Australian Open champion No. 8 Madison Keys, the US group also includes No. 10 Emma Navarro and No. 12 Amanda Anisimova, as well as unseeded players No. 54 Danielle Collins and No. 55 Hailey Baptiste.

With matches against Świątek and No. 7 Mirra Andreeva, respectively, Collins and Baptiste have a tough third round ahead — though Navarro's battle against the 2024 champ Krejčíková arguably headlines Saturday's slate.

How to watch Wimbledon this weekend

While world No. 1 Aryna Sabalenka is still holding strong in the dwindling field, this year's Wimbledon play is proving that the London Slam is anyone's to take, as the grass court humbles even the sport's top stars.

Expect the twists and turns to continue as tennis's best battle for spots in Sunday's Round of 16.

Round-of-32 Wimbledon play kicks off at 6 AM ET on Friday, with live continuous coverage of the tournament airing on ESPN.

The 2025 European Championship is officially underway, as Euro action kicked off with a group-stage upset on Wednesday.

Though the 2025 UEFA tournament's opener was a sweltering affair amid a European heat wave, world No. 26 Finland prevailed, earning a 1-0 upset win over No. 14 Iceland in Group A.

Finnish winger Katariina Kosola played hero, curling in the winning goal in the match's 70th minute — just 12 minutes after Iceland midfielder Hildur Antonsdóttir picked up the competition's first red card.

"The result is important for our confidence," Kosola said after Finland's first major tournament win since the 2009 Euro. "It was the kind of goal I have been practicing a lot."

"It's terrible to lose and we feel frustrated," said Iceland head coach Thorsteinn Halldórsson. "It is an even group and we knew Finland were good, but our first half wasn't good enough."

Elsewhere, No. 16 Norway closed out Wednesday's slate on top of Group A, taking three points by defeating host No. 23 Switzerland in day's second match.

Led by captain and 2018 Ballon d'Or winner Ada Hegerberg — who pulled the match even with a second-half strike — Norway battled to a 2-1 comeback win, despite the Swiss side outshooting and out-possessing the Norwegians.

How to watch this week's 2025 Euro action

Group B steals the 2025 Euro spotlight on Thursday.

While No. 13 Italy snagged a 1-0 opening win over No. 20 Belgium to kick off the day, 2023 World Cup champions and tournament favorite No. 2 Spain will face No. 22 Portugal at 3 PM ET.

Friday's Group C slate will pit No. 12 Denmark against No. 6 Sweden at 12 PM ET, before No. 3 Germany contends with No. 27 Poland at 3 PM ET.

Closing out the first group-stage matches will be arguably the toughest draw of the 2025 Euro pool.

Saturday's Group D slate features major tournament debutants No. 30 Wales against the No. 11 Netherlands at 12 PM ET, with No. 10 France taking on defending champions No. 5 England to cap the day at 3 PM ET.

Live coverage of 2025 Euro matches will air across Fox Sports platforms.

The world No. 1 USWNT ruled the pitch on Wednesday night, shutting out North American rivals No. 8 Canada 3-0 to finish the international window on a high note.

Catching the Canada backline sleeping, US midfielder Sam Coffey opened the scoring at the 17-minute mark before 19-year-old Claire Hutton claimed her first-ever USWNT goal by heading in a Rose Lavelle corner kick in the game's 36th minute.

Houston Dash forward Yazmeen Ryan then padded the US tally in the waning minutes of the match, finding the back of the net just eight minutes after subbing onto the field.

Despite fielding a young roster, the US overpowered a veteran-heavy Canada side in almost every category, topping their Northern neighbors in shots, shots on target, possession, and — most notably — set pieces.

Canada ultimately couldn't match the game's mental pace or physical battle, as the USWNT scored all three goals off dead ball situations — a free kick, a corner kick, and a throw-in.

"It's not about the opponent," US head coach Emma Hayes said after the match. "It's about what we do, and I felt that was extremely dominant."

With Wednesday's contributions, the USWNT finishes the summer window with 11 goals scored across the three friendlies — and zero goals conceded.

The US now enters an extended break before reconvening for another as-yet-unannounced friendly series in October — but players will be expected to perform in the meantime.

"I said to the players in the end in the huddle, if you want to compete to win the biggest things, it's not what you do here that matters," said Hayes. "It's what you do when you go back to your club."

The 2025 WNBA regular season returns on Thursday night, with teams at the top of the league standings looking to prove their mettle against close competition across the long holiday weekend.

The No. 5 Seattle Storm have arguably the toughest weekend assignments, taking on the No. 4 Atlanta Dream on Friday before tackling the No. 3 New York Liberty on Sunday.

Four middle-of-the-pack teams will look to close in on a double-digit season win tally while the league's frontrunners strive to maintain their advantage in this weekend's slate:

• No. 7 Las Vegas Aces vs. No. 8 Indiana Fever, Thursday at 7 PM ET (Prime): Though still without star Caitlin Clark, the Fever hope to harness their 2025 WNBA Commissioner's Cup victory momentum against an Aces side tied with Indiana with an 8-8 season record.

• No. 5 Seattle Storm vs. No. 4 Atlanta Dream, Thursday at 7:30 PM ET (WNBA League Pass): Seattle will look to make strides against a strong Atlanta side while putting last Sunday's stinging 84-57 loss to up-and-comer Golden State in their rearview.

• No. 6 Golden State Valkyries vs. No. 1 Minnesota Lynx, Saturday at 8 PM ET (WNBA League Pass): The rising Valkyries must face a Lynx side hunting redemption, as the league-leaders look to bounce back from their stifling Tuesday Commissioner's Cup upset loss.

• No. 5 Seattle Storm vs. No. 3 New York Liberty, Sunday at 1 PM ET (CBS): With injured Liberty center Jonquel Jones still sidelined, the Seattle Storm will have a chance to steal a weekend game against the reigning champs, as New York struggles to re-find their footing.

With the 2025 WNBA All-Star break looming, early top performers must keep standards high if they want to hold the line when the season crosses the midway point.
