In her first-ever Grand Slam quarterfinal victory, No. 6-seed Jessica Pegula knocked No. 1 Iga Świątek​ out of the 2024 US Open in straight sets Wednesday night.

Now in uncharted territory, the US tennis star will aim at extending her historic run in tonight's semifinal against unseeded Czech opponent, Karolina Muchová.

Quarterfinal victory proved Pegula's dominance

The 30-year-old Pegula, who has yet to drop a set all tournament, took control of yesterday's match immediately, winning the first game on Świątek's serve — the five-time Grand Slam winner's first broken serve in 26 games.

Świątek, the 2022 US Open champion, committed 18 unforced errors in the first set. Visibly frustrated with her performance, the Polish phenom retreated to the locker room to regroup — a move that ultimately proved unsuccessful in the wake of Pegula's relentless 6-2, 6-4 victory.

After six previous Grand Slam quarterfinal attempts, Pegula celebrated, telling the crowd post-match that "there have been so many freaking times, and I just kept losing.... So thank God I was able to do it. And finally — finally! — I can say, 'Semifinalist.'"

Two US contenders will feature in tonight's semis

Pegula isn't the only contender making her Grand Slam semifinal debut tonight. Before Pegula takes the court, fellow US player No. 13 Emma Navarro will take on reigning back-to-back Australian Open champion No. 2 Aryna Sabalenka.

Sabalenka, who fell to US star Coco Gauff in last year's US Open, hopes for better luck against Navarro — the player who ousted the No. 3 defending champ last weekend.

If both Pegula and Navarro emerge victorious, Saturday's US Open final would be the first contested by two US athletes since Sloane Stephens defeated Madison Keys for the 2017 title. It would also pit two New York locals against each other on their home Grand Slam court: Pegula hails from Buffalo, NY, while Navarro was born in NYC.

Navarro and Sabalenka will kick off tonight's Grand Slam action at 7 PM ET, with Pegula's match against Muchová immediately following. Both semis will air on ESPN.

Ticket prices are skyrocketing across the WNBA, with commissioner Cathy Engelbert addressing the surge after several New York Liberty fans wore T-shirts in protest of the increase.

Donning orange shirts emblazoned with the phrase "We've been priced out," New York fans came together to express their frustrations at a recent game.

The WNBA fans' custom shirts referred to season ticket price jumps of more than 250%, saying the Liberty is asking upwards of $30,000 for 2026 renewals.

Some New York season ticket holders noted that their 2026 renewal more than triples the cost they paid for the team's 2024 championship-winning campaign.

The exponential increase isn't just occurring in the New York market, however — it points to an overall rise in ticket prices across the WNBA.

The WNBA's recent ticket surge has seen seats across the league jumping by an average cost increase of 43% in the last year alone.

"In order to fund all these investments that owners are making, and obviously paying the players more which we will do in this next CBA cycle…that's the reality," Engelbert said on Thursday's episode of In Case You Missed It with Khristina Williams. "That's our responsibility as a league and team owners."

Calling the price hikes a result of "simple economics" and "high demand," Engelbert acknowledged the effect on fans, though did not address potential solutions.

"I realize there's some concern out there, certainly that we don't price out our kind of core fan base," she noted.

Chelsea FC is playing it close to the chest, with big-name new signing Alyssa Thompson and previously injured superstar Sam Kerr waiting in the wings as manager Sonia Bompastor teases a 2025/26 WSL season debut for the pair.

Kerr joined the 18-player game-day roster for Chelsea FC's opening-day victory over Manchester City last Friday, but saw her season debut delayed as the Australian remained an unused sub while Thompson greeted fans from the stands.

This Sunday's matchup against Aston Villa provides another chance for the standouts to take the pitch, as the six-time reigning WSL champs hunt another result.

"With Alyssa, we are looking for her to be able to play. We don't have the confirmation yet, but we are hoping for her to be able to play in this game," Chelsea boss Sonia Bompastor said earlier today. "I think she has already shown some good things this week in training, and we can see what she can bring to the team."

Bompastor went on to call last week's decision to keep Kerr on the bench "my choice," saying "She's doing everything she can to be available for the squad and available to start…. The next step for her is to be involved in a short game in the league, and maybe we'll see that on Sunday."

USWNT fans will not get a glimpse of defender Naomi Girma, however, as the January 2025 Chelsea addition sat out last Friday's clash with a calf injury and remains unavailable.

With the possibility of Thompson and Kerr taking the WSL pitch, Chelsea will visit Aston Villa at 7 AM ET on Sunday, with live coverage of the match streaming on ESPN+.

Splashy new Gotham FC addition Jaedyn Shaw is returning West, as the No. 6 NY/NJ club preps for a Friday night clash against the No. 3 San Diego Wave — Shaw's original NWSL team — days after signing the USWNT prospect from the No. 11 North Carolina Courage.

"I'm so excited to be a part of this incredible club and community," the 20-year-old said after her NWSL-record $1.25 million transfer to Gotham. "I'm looking forward to playing alongside world class players and giving my all to help the team win another championship."

After finding immediate success with the Wave in 2023, Shaw requested a trade to the Courage in January 2025, initiating what turned out to be a short stint in Cary, NC.

"I've grown so much just over the past few months, being at the Courage," Shaw told ESPN on Thursday. "I feel like I've matured a lot. I've had to experience things that I haven't necessarily experienced in my career and having to deal with those things."

Gotham and Shaw are currently "working toward an updated and extended contract," per a team release on Thursday, with the young attacker looking to boost Gotham's offense while adding to her 16-goal and five-assist NWSL career tally.

Shaw could take the pitch for No. 6 Gotham in her new club's Friday night visit to the No. 3 San Diego Wave.

The match kicks off at 10 PM ET, with live coverage airing on Prime.

The No. 1 Kansas City Current are closing in on the 2025 NWSL Shield, gearing up for a Saturday night showdown against the No. 2 Washington Spirit that could inject insurmountable distance between the Current and the rest of the league.

With a 14-point lead at the top of the NWSL standings, Kansas City has already clinched a postseason berth, and the Current only need only a few more results to secure a franchise-first league trophy.

Even more, KC enters Saturday's match on an 11-game unbeaten streak, with the Current hosting the Spirit at their home CPKC Stadium — a pitch where Kansas City has yet to drop a match this year.

Despite that dominance, it may not be smooth sailing for the Current, as Washington's future is beginning to take shape behind recently returned star Trinity Rodman, whose brace lifted the Spirit over the No. 7 Seattle Reign last Sunday.

"She's not back, because she's a different player," Washington head coach Adrián González told reporters about Rodman's level of play. "After her injury, she's more prepared mentally. She's having enough time to get the minutes, the training, and the exposures that she needs with no pressure."
