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.

The USWNT announced their 2025 season finale on Monday, setting a pair of friendlies against Italy at Orlando's Inter & Co Stadium on November 28th and Chase Stadium in Fort Lauderdale on December 1st.

Facing the now-world No. 2 US for the first time in 15 years, Italy's recent run to the 2025 Euro semifinals shot them to No. 12 in the FIFA rankings.

"As we prepare for World Cup qualifying at the end of 2026, we want to play teams from all parts of the world with different styles and different strengths, so getting to play Italy, one of Europe's up-and-coming teams, will be a great way to end the year," said USWNT head coach Emma Hayes in a statement announcing the friendlies.

After an extended break following a series of early July matchups, the US now has five matches left on the books, with the year-ending Italy matches rounding out three already-announced October friendlies.

The USWNT kicks off next month's lineup with two matches against Euro 2025 participant No. 23 Portugal, followed by a third friendly against No. 33 New Zealand.

As Hayes's year of roster evaluation comes to a close, expect stakes to rise as the 2027 World Cup comes into sharper view.

The red-hot No. 2 Las Vegas Aces will hit the court in the 2025 WNBA Playoffs again on Tuesday night, facing off against the No. 7 Seattle Storm in Game 2 of the postseason's first round with an eye on scoring their 18th consecutive victory — and a trip to this year's semifinals.

"You guys celebrate this more than we do," MVP frontrunner A'ja Wilson said, brushing off the team's recent dominance. "The streak stopped in the regular season."

"It's the first to nine wins [for the championship], so that's how we want to approach it," Las Vegas head coach Becky Hammon echoed, voicing a renewed focus on retaking the WNBA crown.

Following the league's new home-away-home first-round format, Seattle has the chance to extend their season on their home court on Tuesday night, as the Storm arrives back in market with few answers after suffering a 102-77 Game 1 loss.

"Our fans deserve for us to play well," said Seattle forward Nneka Ogwumike. "We have to figure out how to do it, no matter what. That's going to be the test on Tuesday."

No. 7 Seattle will try stay alive against No. 2 Las Vegas at 9:30 PM ET on Tuesday, with live coverage of Game 2 of the 2025 WNBA Playoffs airing on ESPN.

With their backs against the wall, the No. 6 Indiana Fever will face down both the No. 3 Atlanta Dream and potential elimination from the 2025 WNBA Playoffs when they host their first home postseason game in nearly a decade on Tuesday night.

"I think you give yourself an edge as the home team. When they punched us, they punched us hard," Indiana guard Kelsey Mitchell said after Sunday's 80-68 loss in Atlanta. "So we have to do the same thing."

"I would like to think that being back at home can kind of give us a sense of comfort, so hopefully we could use it for what it's worth and not take it for granted," she continued.

Mitchell will likely be the key to the Fever's survival, after an onslaught of season-ending injuries forced the three-time WNBA All-Star to step up as a scoring leader — with Mitchell dropping a postseason career-high 27 points in Sunday's Game 1.

"It's a lot of little things," said Indiana head coach Stephanie White following the weekend result. "I like where we are, I'm proud of our group for continuing to fight, and we're going to be better on Tuesday."

WNBA legend Elena Delle Donne is returning to the court, with USA Basketball announcing on Monday that the two-time league MVP will join the 3×3 Women's National Team as its first-ever managing director.

The 36-year-old officially retired in April 2025 after struggling with injuries, capping a career that spanned winning gold at the 2016 Olympics and the 2018 FIBA World Cup with Team USA as well as two WNBA championships.

"Elena has been a member of the USA Basketball family for almost 15 years," USA Basketball CEO Jim Tooley said in Monday's press release. "Her wealth of knowledge of the sport of basketball and our organization will be an asset as we continue our journey."

As part of her duties, Delle Donne will be responsible for selecting the USA Basketball 3x3 team's coaching staff and players prior to the 2028 LA Olympics, the FIBA 3x3 World Cup, and other major international competitions.

"USA Basketball was an important part of my on-court career for a decade and a half. To have the opportunity to continue my journey with the organization, and to help shape and grow the 3x3 program, is something that I take very seriously," Delle Donne said. "I'm excited to get started."

Delle Donne's new position is the 3x3 version of fellow WNBA icon Sue Bird's role, as the newly minted Hall of Famer became the managing director of the USA Basketball women's 5x5 arm in May.

"To now think that I'm going to be on the other side of the phone letting someone know that their dream has come true and they've made the team is going to be such a fulfilling, full circle moment for me," Delle Donne said.
