In the biggest upset of the 2025 Australian Open so far, 19-seed Madison Keys defeated world No. 2 Iga Świątek in a back-and-forth three-set semifinal early Thursday morning.

Entering as the tournament's only athlete to win every set, five-time Grand Slam champion Świątek conceded more games to Keys than in her previous five Australian Open matches combined.

Keys's speedy serve and heavy forehand paired with a Świątek double-fault pushed the match to a tie-break decider, with the US star ultimately winning 5-7, 6-1, 7-6 (10-8).

"It just became who can get that final point and who can be a little bit better than the other one," Keys said post-match. "I'm happy it was me."

Keys's victory is just the latest chapter in a 2025 Australian Open run that's seen her beat three Top 10 contenders in Świątek, No. 6 Elena Rybakina, and No. 10 Danielle Collins. Those victories earned the 29-year-old her own Top 10 spot in next Monday’s WTA rankings.

With Thursday's win, Keys booked her second-ever Grand Slam championship match, returning to the sport's top stage for the first time since the 2017 US Open.

One last challenge awaits Keys

To claim her career's first Grand Slam trophy, however, Keys will have to defeat reigning champion and world No. 1 Aryna Sabalenka, who comfortably downed Spain's No. 11 Paula Badosa 6-4, 6-2 on Thursday in pursuit of a third-straight Australian Open title.

In their five previous meetings, Keys has only beaten Sabalenka once, topping her in Berlin in 2021.

Sabalenka won their most recent bout in the 2023 US Open semifinals. However, that three-set slog was similar to Keys's gritty victory over Świątek and, if she can maintain the composure and energy she displayed on Thursday, the US star's momentum could fuel her to similarly stun Sabalenka.

Saturday's Australian Open final between Keys and Sabalenka will take the court at 3:30 AM ET, with live coverage on ESPN.

Five-time Olympic medalist and USA track star Gabby Thomas will miss this month's 2025 World Athletics Championships in Tokyo due to a lingering Achilles injury, the 28-year-old sprinter announced on Tuesday.

Thomas, who captured a full trio of gold medals at the 2024 Paris Games, has been dealing with the injury since May, going on to re-aggravate it in July prior to August's 2025 USATF Outdoor Championships, in which she placed third in her favored 200-meter race — narrowly booking her spot at the World Championships by a mere one-thousandth of a second margin.

"I understand that it will be disappointing for some track fans to hear this news, but I've finally come to the realization that it's OK to be human and take care of myself," she said in a statement.

"As an athlete you always want to keep grinding, but sometimes you simply can't outwork an injury," Thomas explained. "Sometimes it's about patience and making the right decision for the long term. All the best to my Team USA teammates fighting for medals in Tokyo."

As one of Team USA's top talents in the 200-meter dash as well as the 4×100- and 4×400-meter relays, Thomas plans to return to competition in 2026.

Bay FC forward Asisat Oshoala is on the move, finalizing a transfer to Saudi Arabian club Al Hilal this week after making 38 appearances for the 2024 NWSL expansion team.

"Asisat has been an incredibly important part of Bay FC history, not only with her impact on the pitch but also through the energy, professionalism, and kindness she brought every day," Bay FC sporting director Matt Potter said in a Tuesday statement. "She is a world-class player and an even better person, and we are grateful for everything she contributed to our club."

One of Bay FC's splashiest signings ahead of their inaugural season, the former Barcelona star led the franchise with seven goals during its debut campaign — including the club's first-ever goal in the team's initial match.

However, the 30-year-old Nigerian national and six-time African Women's Footballer of the Year has since seen her NWSL playing time drop, logging just 12 appearances in 2025 so far.

Oshoala isn't the first high-profile NWSL player to transfer to the 10-team Saudi Women's Premier League since its 2022 debut — the same year that the Middle East country founded its women's national team.

Following the Orlando Pride's 2024 Shield and Championship-winning season, Brazilian star Adriana joined Saudi side Al Qadsiah FC for a then-club-record $500,000 transfer fee.

Unrivaled 3×3 Basketball is doubling down on NIL, spotlighting the offseason league's deep roster of NCAA talent in its "Future Is Unrivaled" (FIU) collection drop on Tuesday.

The new merch line features FIU-branded sports apparel and accessories alongside one-offs like pleated skirts, button-ups, and jackets, all backed by a social media campaign starring college stars Lauren Betts (UCLA), Sienna Betts (UCLA), Madison Booker (Texas), Audi Crooks (Iowa State), Azzi Fudd (UConn), MiLaysia Fulwiley (LSU), Hannah Hidalgo (Notre Dame), Flau'Jae Johnson (LSU), Ta'Niya Latson (South Carolina), Olivia Miles (TCU), Kiki Rice (UCLA), Sarah Strong (UConn), Syla Swords (Michigan), and JuJu Watkins (USC).

After first signing NCAA stars Paige Bueckers and Flau'Jae Johnson in late 2024, Unrivaled added more than a dozen of college basketball's biggest names to its "Future is Unrivaled" Class of 2025 earlier this summer.

While they cannot play in the upstart league prior to turning pro, the NIL signees did participate in July's Unrivaled Summit, a multi-day event in Miami that focused on skill development, content creation, brand building, social media strategy, and community service.

Unrivaled basketball's investment in the next generation of superstars underlines the 3×3 venture's growing influence in the sport, as it becomes a wedge issue in the WNBA's ongoing CBA negotiations while prepping to tip off a second season in January.

The No. 5 New York Liberty finally punched their ticket to the 2025 WNBA Playoffs, as the 2024 champs secured a postseason berth thanks to a Tuesday night loss by the No. 8 Indiana Fever — despite their own 66-58 defeat at the hands of the surging No. 6 Golden State Valkyries.

With star guard Sabrina Ionescu still sidelined with injury, the Liberty only scored 26 first-half points in the matchup, becoming just the second reigning title-holders to fall to a first-year expansion team in WNBA history.

"We just lost a game," New York head coach Sandy Brondello said afterwards. "Obviously, we're in the playoffs, but we still lost a game. Liked the second half, didn't like the first half that much."

With the Fever falling 85-79 to the No. 4 Phoenix Mercury, tension in the WNBA standings has hit a new high as four teams — No. 6 Golden State, No. 7 Seattle, No. 8 Indiana, and No. 9 Los Angeles — battle for the last three playoff spots.

Golden State is hot on the heels of New York, shooting to become the first-ever expansion team to make the playoffs in their debut year as their magic number dwindles down to two — with four games left on the Valkyries' regular-season docket.

"We're in playoff mode right now!" Golden State center Temi Fagbenle, who put up a team-leading 16 points in Tuesday's win, told the Valkyries' crowd.

The No. 6 Valkyries have a chance to close in on history during their Thursday date with the last-place Dallas Wings, which tips off at 10 PM ET on WNBA League Pass.

Meanwhile, the No. 5 Liberty will look to regroup during their Friday visit to the No. 7 Seattle Storm, which airs live at 10 PM ET on ION.
