World No. 1 Ash Barty is retiring from tennis, she announced Wednesday in a video posted to her Instagram account.

The three-time Grand Slam champion is less than two months removed from her Australian Open win. The 25-year-old became the first Australian player to win the major since 1978. She also became the second active player next to Serena Williams to win majors on all three surfaces.

After her Australian Open win in January, she withdrew from Indian Wells and the Miami Open, citing an ongoing need for recovery. At the time, she said she aimed to return for the Billie Jean King Cup in April.

On Wednesday, though, Barty shared her plans to retire from the sport in a video with her close friend and former doubles player Casey Dellacqua.

“I just know at the moment, in my heart, for me as a person, this is right,” Barty said. “As a person this is what I want. I want to chase after some other dreams that I’ve always wanted to do and I’ve always had that really healthy balance, but I’m really really excited.”

This is not the first time that Barty has stepped away from tennis. In 2014, she took a break, citing burnout and the overwhelming pressure and travel required. Her hiatus came three years after winning the Wimbledon junior championship at age 15.

She took up cricket, playing professionally in Australia, before again picking up her racket and returning to tennis in 2016.

Following her return, Barty won the 2019 French Open on clay and the 2021 Wimbledon on grass, and then she won on the hard courts at Melbourne Park in January. Since first turning pro in 2010, she has won 15 tour-level titles in singles and 12 in doubles. She’s spent the past 114 weeks atop the world rankings, bringing her career total to 121 weeks.

She retires having earned $23,829,071 on tour.

“I know I’ve done this before, but in a very different feeling,” Barty said. “And I’m so grateful to everything that tennis has given me. It’s given me all of my dreams possible, but I know that the time is right now for me to step away and chase other dreams.”

She’s not the first tennis player to walk away at the top of their game. Justine Henin retired in May 2008 at No. 1 in the world, having spent 61 consecutive weeks atop the rankings, also at the age of 25. She returned two years later, reaching the 2010 Australian Open final before retiring for good in 2011.

Revealing that the conversations about walking away began after she won Wimbledon, Barty said that there was “just a little part of me” that wasn’t fully satisfied. Then came the Australian Open.

“To be able to win Wimbledon which was my dream, my one true dream that I wanted in tennis, that really changed my perspective,” she said. “Then came the challenges of the Australian Open and I think that for me just feels like the most perfect way, my perfect way to celebrate what an amazing journey my tennis career has been.

“I’m fulfilled, I’m happy, and I know how much work it takes to bring the best out of yourself…I just know physically I have nothing more to give and that for me is success. I’ve given absolutely everything I can to this beautiful sport of tennis and I’m really happy with that.”

US Soccer submitted its World Cup bid book to FIFA last week, naming 14 US stadiums among the 2031 tournament's 20+ proposed North American host venues.

The four-country joint bid for the 2031 World Cup spanned cities across host nations USA, Mexico, Costa Rica, and Jamaica, with the quartet collectively identifying 50 potential stadiums while also designating their proposed core of 20 venues.

In the US, stadiums in Atlanta, Charlotte, Houston, Los Angeles, Kansas City, and Seattle made the proposed shortlist, as well as Arlington, Texas, and East Rutherford, New Jersey, among others.

Mexico City, Guadalajara, Monterrey, and Torreón made Mexico's primary proposal, while Costa Rica and Jamaica put forward San Jose and Kingston, respectively.

The bid includes both soccer and football venues, with secondary venues also listed as possible options in eight of the first-choice US cities.

Additionally, the bid book pegged Atlanta as the World Cup draw host and Dallas as the tournament's international broadcast center, though FIFA will likely not make final decisions on 2031 venues until after the 2027 competition in Brazil.

"By proposing more than the required 20 sites, the joint bidders demonstrate a commitment to securing the best possible hosting conditions and ensuring the tournament represents the full diversity of our region on a global scale," FIFA stated.

The WNBA and WNBPA agreed to a second CBA extension late Sunday night, officially pushing the contract's deadline to January 9th, 2026, to allow for 40 more days of negotiations.

Like the original CBA extension from October 31st to December 1st, either the WNBA or WNBPA now has the option to terminate the agreement with 48 hours of notice.

"We expect substantive movement from the league within this window," the players union told Front Office Sports, while the WNBA issued a statement saying both parties are "continuing to work toward a new agreement."

While total annual compensation offers have reportedly crossed the million-dollar mark for players earning the league's maximum, the WNBA's salary model — particularly in regards to revenue sharing — remains a core issue.

According to sources, the WNBA's proposal offers players a revenue-sharing option only after reaching certain minimums, while the WNBPA continues to advocate for a bigger cut of the exponentially growing league.

The players union is also reportedly advocating for a salary cap that increases with the league's income, rather than at an arbitrarily fixed growth rate.

With important offseason processes like the planned two-team expansion draft to stock incoming 2026 WNBA franchises the Portland Fire and Toronto Tempo now delayed until a new CBA is in place, the pressure is approaching new highs on both sides of the negotiating table.

No. 4 Texas blew past two top-ranked opponents last week, setting the tone for the 2025/26 NCAA basketball season with back-to-back wins over No. 3 UCLA and No. 2 South Carolina to earn the Players Era Championship trophy on Thanksgiving Day.

Fifth-year senior Rori Harmon was named tournament MVP, putting up a game-leading 26 points and breaking the Longhorns' career assists record in Wednesday's 76-65 defeat of UCLA before hitting the game-winner to lift Texas over the Gamecocks 66-64 in Thursday's title game.

"I just read the vibe and flow of the game," Harmon said afterward. "[Texas head coach Vic Schaefer] called the play at the end of the game, and I've been in this moment before, so it felt good coming out of my hands."

Texas's win added fuel to the burgeoning SEC rivalry, with the teams squaring off five times in the last year — and South Carolina riding a narrow 3-2 advantage.

"I'm not upset at all," Gamecocks coach Dawn Staley said postgame. "This is going to help us because there are a lot of things to unpack in it."

"If you can give [Texas] a run for their money in that way, I mean, you're on to something," she continued. "I like our resiliency. We've just got to clean up some things at the end of the game."

How to watch Texas, South Carolina this week

Both Texas and South Carolina have another ranked matchup on this week's NCAA docket, with the No. 4 Longhorns taking on the No. 12 UNC Tar Heels while the No. 2 Gamecocks face the No. 23 Louisville Cardinals.

Both games tip off at 7 PM ET on Thursday, with Texas vs. UNC airing live on ESPN2 while South Carolina vs. Louisville airs on ESPN.

After a year of testing and experimentation, the USWNT will look to close out 2025 on a high note on Monday night, when the world No. 2 squad faces No. 12 Italy in the second of the pair's winter friendlies.

"I've been very clear on the process to develop players and what we have to go through, so I'm not zoomed in on three losses," US manager Emma Hayes said of the team's 2025 shortcomings. "If I was, I wouldn't make changes."

"We work in an environment we're really proud of," she continued. "It's a very inclusive environment, diverse environment, and all these things contribute to the culture that hopefully leads to long-term success."

In line with her ongoing rotational philosophy, Hayes indicated that fans in Fort Lauderdale on Monday could see a departure from the combination of players that defeated Italy 3-0 in Orlando on Friday — as well as new tactics from the 2025 Euro semifinalists.

"My whole argument is that no matter who plays, the level of performance should still be high," Hayes said.

The US saw 16 players debut this year — the most since 1985 — with 51% of the team's combined 39 goals and 26 assists in 2025 involving a player under 25 years old.
