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.

Former Chicago Sky guard Allie Quigley made her retirement official on Tuesday, announcing her exit from professional basketball in a piece for The Players Tribune, nearly three years after her final WNBA game in September 2022.

The 14-year league veteran spent the last decade of her career playing for her hometown team, helping lead the Sky to a WNBA championship in 2021 while also picking up three All-Star nods and two WNBA Sixth Woman of the Year awards.

With a career average of 10.9 points per game and 39.4% shooting from beyond the arc, Quigley also claimed four 3-Point Contest victories, winning in 2017, 2018, 2021, and 2022 to set a record that still stands across the WNBA and NBA.

Chicago's all-time leading scorer for years, Sky guard Courtney Vandersloot — Quigley's wife — usurped her crown just two weeks ago.

"I love knowing that I can look back on my career and say it was really, really good — but it was part of the beginning of something truly great," Quigley wrote.

Explaining that she "never actually meant to do an Irish goodbye," Quigley initially took time off to become a mom, a process that took longer than expected.

Alongside Vandersloot, Quigley welcomed their first child, daughter Jana Christine, on April 8th — an event that spurred her to officially announce her retirement.

"[A]s special as the Sky winning a championship felt, and as proud of a moment as that was, bringing a baby into the world is our accomplishment we're most proud of," said Quigley.

On Tuesday, 2024/25 UEFA Champions League winners Arsenal announced that the Gunners are making the 60,704-capacity Emirates Stadium their permanent home for all WSL matches on the heels of last season's successful nine-game run in the north London venue.

Arsenal dominated the WSL in attendance during their 2024/25 campaign with a total of 415,000 tickets sold, a 20% increase over the Gunners' 2023/24 season.

Even more, the club averaged crowds of over 34,000 fans for the team's nine matches hosted at the men's side's historic Highbury home.

Both Arsenal's and the league's season-high attendance came in February, when 56,784 fans packed Emirates for the Gunners' North London Derby match against Tottenham.

While all of Arsenal's 11 WSL home games will kick off at Emirates, the reigning European champs will open their UWCL defense at the significantly smaller, 4,500-capacity Meadow Park, with future Champions League matches moving to Highbury should the Gunners advance to the tournament's knockout rounds.

"For us, this is just the beginning, and bringing every WSL match to the Emirates is another step for more supporters to be part of this special journey," said Arsenal head coach Renée Slegers in a club statement. "We'll come back next season, with fire in our hearts, more determined, more ambitious, and more together than ever."

Women's teams are big business, with global sports business conference SPOBIS International reporting this week that average WNBA franchise valuations rose to $90 million in 2024, while NWSL clubs weighed in at $104 million — doubling their 2023 mark.

In May, the reigning WNBA champion New York Liberty sold shares at a $450 million valuation, qualifying them as the world's most valuable women's sports team.

SPOBIS's top five includes the WSL's Chelsea FC ($326 million) alongside NWSL side Angel City FC ($250 million), the WNBA's Dallas Wings ($208 million), the Kansas City Current ($182 million), and the Las Vegas Aces ($140 million).

US women's sports teams hold a key advantage in the race to the top of the valuations table, with WNBA and NWSL squads able operate independently from men's systems.

Having separated from their men's side last year, Chelsea FC was the only non-US team to make the list, bolstered by Reddit co-founder Alexis Ohanian's $26.6 million purchase of a 10% stake in the 2024/25 WSL champs last month.

Other European teams in line for similar value boosts include OL Lyonnes and the London City Lionesses, both independently owned and operated by Washington Spirit owner Michele Kang.

With many factors contributing to a team's overall value — namely capital, media deals, viewership, ownership structures, and popularity — it's tough to predict the next big thing in women's sports, but these numbers point to a red-hot market across major pro leagues.

US Soccer is heading back to college, announcing Tuesday that the federation is launching a NextGen College Soccer Committee (NCS) to help solidify NCAA soccer's place in the national development system.

The NCS will "aim to integrate the college game more deeply into the broader US Soccer ecosystem, while ensuring it remains a strong, sustainable platform for student-athlete education, player development, and community engagement."

As professional soccer careers become more viable on the women's side, an increasing number of prospects are opting to sign directly with clubs out of high school rather than follow the traditional collegiate track.

Skipping college to go pro is common in other countries, where many clubs run their own academies for promising young players.

To "properly consider the development pathway and progression to college soccer," US Soccer is also working with pre-professional organizations like Elite Clubs National League, Girls Academy, and other US youth leagues.

Members of the NCS include Kansas City Current co-owner Angie Long, NWSL COO Sarah Jones Simmer, and former Duke standout and current MLS executive Ali Curtis.

With Tuesday's announcement, US Soccer appears to be acknowledging the challenges of maintaining NCAA soccer's appeal in the face of increasingly diverse pro opportunities — while also doubling down on the value of the college game.

"College soccer is integral to the fabric and future of our sport in this country," said US Soccer CEO JT Batson. "The individuals joining this group bring unique perspectives and expertise that will help us build a model where college soccer can thrive in a modern, connected system."
