US tennis player Madison Keys earned her first-ever Grand Slam title on Saturday, taking down back-to-back defending champ and world No. 1 Aryna Sabalenka in the 2025 Australian Open final.

On the heels of a three-set semifinal ousting of No. 2 Iga Świątek last Thursday, Keys' 6-3, 2-6, 7-5 Saturday victory made her the first player to upset both the world No. 1 and No. 2 in the same Grand Slam since Svetlana Kuznetsova did so at the 2009 French Open. The 29-year-old is also the first to do it in Melbourne since Serena Williams in 2005.

Only three other WTA players have racked up more Grand Slam main draws before winning their first title. On Saturday, Keys tied Caroline Wozniacki for making the most Australian Open main-draw singles appearances before lifting the trophy.

Keys's Australian Open run included five wins over seeded opponents, four of them in the WTA's Top 10 entering the tournament. Plus, with five three-set victories, Keys tied the record for the most three-set wins at any of the four Grand Slams.

However, none of those records compare with winning her first major.

"I’ve wanted this for so long," Keys said holding her trophy during the post-match ceremony.

Keys' championship was years in the making

Keys burst onto the pro scene on her 14th birthday back in 2009, and has been a Top 20 mainstay for most of the last decade.

The US star has appeared in at least the quarterfinal round of all four majors multiple times. However, she had only one Grand Slam final under her belt prior to this weekend's championship match — a 2017 US Open loss to Sloane Stephens.

Ultimately, it took relinquishing her desperation to win a Slam to actually snag that elusive trophy.

"I've done a lot of work to no longer need [winning a Grand Slam]," Keys explained after her win. "I really wanted it, but it's no longer the thing that was going to define me, and kind of letting go of that burden, I finally gave myself the ability to play for it."

Slam win returns Keys to the WTA's Top 10

The WTA updated their rankings early Monday, with Keys's breakthrough performance boosting her to No. 7 — her first Top 10 slot since January 2023. The new rank also ties her career-high, with Keys first peaking at No. 7 in October 2016.

Keys's rise also solidifies the US as arguably the nation most flush with the sport's top talent. The US now boasts four players in the Top 10, with Keys joining No. 3 Coco Gauff, No. 6 Jessica Pegula, and No. 9 Emma Navarro. No other nation has more than one athlete in that elite tier.

That said, the WTA's best stayed put in Monday's rankings. Despite their Australian Open losses, all four top seeds — Sabalenka, Świątek, Gauff, and No. 4 Jasmine Paolini — retained their top spots.

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.
