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.

LOVB volleyball is coming back to cable, as the pro volleyball league announced a Wednesday night primetime partnership with USA Network for its 2026 season.

With the rookie card of Indiana Fever star Caitlin Clark still doing numbers, trading card manufacturer Panini America is debuting Caitlin Clark Chronicled this week, dropping a limited-edition release on Monday that features a 22-page collectible book and 100-card set of the WNBA standout.

The book spans images of Clark on and off the court, and includes eight four-card packs and 32 randomly inserted trading cards, as well as autographed exclusives.

"I'm excited to launch 'Caitlin Clark Chronicled' with Panini America and share some of my favorite moments on and off the court from my first two years in the WNBA," Clark said in Monday's statement. "We wanted to create something different that combined great photography with trading cards, including some special exclusives. I am proud of this collection and hope fans enjoy it."

The WNBA superstar is an exclusive Panini partner in the trading card and autographed memorabilia space, with Clark making headlines last July when her one-of-one autographed rookie card sold for more than $600,000 — setting a new world record for a women's sports card.

Panini's limited edition Clark collection is currently available for purchase at Target stores and Target.com.

Tensions remain high between the WNBA and WNBPA, after The Athletic reported on Monday that the latest CBA proposal from Players Association more than doubles the league's revenue share offer — suggesting a deepening rift in negotiations.

The union outlined a deal that would give players around 30% of total WNBA and team revenue — a significant leap from the league's proposed 15% share.

According to sources, the WNBPA also suggested linking the salary cap to the previous season's total revenue, factoring in player benefits and the number of teams in the league.

The move intends to undercut an accusation from the WNBA that the players have yet to put forward an economically viable revenue sharing model.

The union's proposal begins at 29% of the prior season's total league grosses, then grows to 34% by the final year of the CBA with a one-time adjustment for the new 11-year, $2.2 billion WNBA media rights deal.

Notably, the league recently rejected a flat 33% revenue share CBA proposal, prompting this week's 1%-per-year increase system in response.

It's clear that the WNBA office and the WNBPA are at odds, but the union is showing their work as both sides strive for a CBA that will keep players on the court in 2026.

Olympic swimming icon Katie Ledecky has done it again, becoming the first woman to break the 15-minute mile with a time of 14:59.62 at her namesake Katie Ledecky Invitational in Maryland.

Smashing her own US record of 15:01.41, Sunday's sub-15 minute mile gives Ledecky the 1,650-meter freestyle's eight fastest times, with US teammate Erica Sullivan earning the ninth-best in 2019.

"This is a special one for sure," Ledecky said afterwards. "This has been a goal of mine, to break 15 minutes in the 1,650, for probably eight or nine years. So, just putting in the hard work, believing that I could do it someday, and to do it at this meet, is really special."

The 28-year-old Washington, DC, product is the most decorated women's swimmer in the history of the sport, prompting Nation's Capital Swimming — where Ledecky got her start at age six — to name their annual event in her honor earlier this year.

"I definitely was a little nervous before the race, just knowing there were a lot of eyes on me and all that," she continued. "But I knew I could just relax and have fun with it, and whatever happened, happened."

Ledecky's next major competition will likely be the TYR Pro Swim Series, which kicks off in Austin on January 14th, 2026.

The domestic competition series will be covered across NBC Sports platforms.
