For only the second time in 13 career tries, 20-year-old US tennis star Coco Gauff defeated former World No. 1 Iga Świątek in straight sets at the 2024 WTA Finals on Tuesday, guaranteeing Gauff a spot in Saturday's semifinals.

No. 3 Gauff clinched the 6-3, 6-4 result in one hour and 48 minutes on Riyadh’s Center Court to join Aryna Sabalenka as the first two players to book tickets to the semifinals.

"I knew going into the match, despite our head-to-head [history], I had a lot of confidence and I felt like I was playing great tennis," Gauff said after the match.

The first and only other time Gauff defeated Świątek was at the 2023 Cincinnati Open, when the pair battled to a 7-6(2), 3-6, 6-4 finish. Gauff went on to win that tournament, just weeks before earning her first Grand Slam championship by winning the 2023 US Open.

Gauff's Tuesday win also guarantees that Sabalenka will finish the calendar year as World No. 1, bolstered by her 2024 US Open win and her strong performances this week.

Semifinals take shape

While Sabalenka and No. 7 Qinwen Zheng both advanced from the Purple Group on Wednesday, ending No. 4 Jasmine Paolini's and No. 5 Elena Rybakina's WTA Finals runs, Gauff and Świątek each have one more group match on the tournament's docket.

Gauff will aim to win the Orange Group outright by defeating No. 8 Barbora Krejčíková on Thursday. As for Krejčíková, she'll be competing for a shot at advancing over Świątek, who will look to defeat alternate Daria Kasatkina to claim the final semifinals spot.

Pegula withdraws with injury

Kasatkina is stepping in at the eleventh hour after Gauff's compatriot, No. 6 Jessica Pegula, withdrew from the competition with a left knee injury on Wednesday.

The 30-year-old Pegula, who was already eliminated from advancing after falling 6-3, 6-3 to Krejčíková on Tuesday, has nursed the injury since before the WTA Finals began.

"What started as a really small issue flared over the last two matches and I just can’t continue tomorrow," Pegula tweeted. "I’m sorry to the fans and tournament. I really had a great week of prep and had high hopes here but it just wasn’t meant to be."

Świątek and Kasatkina will kick off the final group-stage day at the 2024 WTA Finals at 7:30 AM ET, with Gauff taking on Krejčíková at 10 AM ET. Both matches will air live on the Tennis Channel.

The PWHL is continuing to break records, as Sunday's 2025/26 Takeover Tour stop in Washington, DC, saw 17,228 fans pack into Capital One Arena to see the No. 2 New York Sirens top the No. 4 Montréal Victoire 2-1 — setting a new US women's hockey attendance record in the process.

The benchmark surpasses the previous US record set this past November, when the Seattle Torrent welcomed 16,014 fans to their inaugural home opener.

Sunday's DC crowd also sees the US mark inch closer to the overall professional women's hockey attendance record, set in April 2024 when 21,105 PWHL fans sold out Montréal's Bell Centre to watch the Victoire take on the Toronto Sceptres.

"Washington, DC, showed up in such a big way, and the energy our fans brought into the arena turned this game into something truly special," PWHL EVP of business operations Amy Scheer said of the first-ever PWHL game in the nation's capital. "Moments like this capture the joy of our sport and the momentum behind the league."

The third-year league is currently racing through its best-attended month on record, drawing more than 154,000 fans across the last 16 games while averaging crowds of 8,726 across all 49 games so far this season.

The Kansas City Current delivered some concerning news this week, with the NWSL club revealing that star striker Temwa Chawinga remains sidelined with an hip adductor injury while the league's 2026 preseason gets underway.

The team currently lists the reigning back-to-back NWSL MVP under a season-ending injury (SEI) designation, a category earned after Chawinga picked up the injury in mid-October, leaving the Kansas City attacker benched for the Current's quarterfinal loss to eventual 2025 NWSL champions Gotham FC.

"It's hard because of the nature of the injury," incoming Kansas City head coach Chris Armas told The Athletic last week. "With Temwa, we've got to be very careful, but she's looking great and doing lots of good work on the return to play."

Also on the Current's SEI list is standout winger Michelle Cooper, with the 23-year-old rising USWNT star suffering a foot injury in Kansas City's final regular-season match of 2025.

"It was a little bit of a tough ending here after, honestly, an amazing historic season," said Armas. "Hopefully they are back as soon as possible, but it's still unclear."

Both Chawinga and Cooper will have some time to recover before Kansas City kicks off their 2026 NWSL regular season against the Utah Royals on March 14th — with teams allowed to lift a player's SEI status any time once the season begins.

The world's top tennis stars are rolling in Melbourne, as the first round of the 2026 Australian Open wrapped early Tuesday morning with only a few ranked seeds suffering early defeats.

World No. 15 Emma Navarro was the highest-ranked US player to fall in the first round, with the 24-year-old exiting the season's first Grand Slam in a 6-3, 3-6, 3-6 loss to Poland's No. 50 Magda Linette on Sunday.

No. 11 Ekaterina Alexandrova also stumbled in the first round, with her Melbourne run ending in a three-set loss to Turkey's No. 112 Zeynep Sönmez on Saturday before No. 68 Peyton Stearns ousted fellow US star and 2020 Australian Open champion No. 30 Sofia Kenin in straight sets on Sunday.

Many contenders still remain in the hunt, however, as the entire WTA Top 10 cruised through their opening matchups to advance to the Slam's second round.

That said, fans will miss out on one highly anticipated showdown, as wild card entry Venus Williams's first-round loss ended the 45-year-old tennis icon's path to a second-round clash with US favorite No. 3 Coco Gauff.

The 2026 Australian Open continues when the Slam's second round kicks off with a Tuesday night slate that features stars like No. 1 Aryna Sabalenka, No. 3 Coco Gauff, and No. 7 Jasmine Paolini.

Tuesday's action begins at 7 PM ET, with all Melbourne matches airing live across ESPN platforms.

The ongoing dominance of UConn basketball has started to break records, as the top-ranked Huskies humbled unranked Notre Dame 85-47 on Monday — keeping their perfect 2025/26 NCAA season intact.

Monday's 38-point margin of victory marked the largest in the teams' 20-year rivalry, with the win also snapping the Huskies' three-game head-to-head losing streak against the Fighting Irish.

"UConn showed why they're the best team in the country," Notre Dame head coach Niele Ivey said postgame.

Even more, UConn sophomore forward Sarah Strong added her own individual history to Monday's tally, becoming the third-fastest Husky to reach 1,000 career points, with the 19-year-old trailing only program legends Maya Moore and Paige Bueckers — who each did so in 55 games to Strong's 59 — in the race to reach that stat.

"I would love to see if anybody has scored 1,000 points by taking less shots than she's taking," said UConn head coach Geno Auriemma. "She's so efficient."

"It means a lot to me I guess, but I wouldn't be able to do it without my teammates," Strong said after leading the Huskies with an 18-point, 11-rebound double-double on Monday night.
