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 explained in an X post. "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."

How to watch Thursday's last group matches of the WTA Finals

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.

With college soccer's regular season officially in the books, DI teams around the country are now competing for conference tournament titles and the NCAA championship bids they guarantee.

Each of Division I's 30 conferences automatically send their tournament winner to the NCAA championship pool, with the rest of the 64-team national bracket decided by the governing body's selection committee by Monday afternoon.

The toughest tickets to grab are in the Power Four conferences, which currently house 20 of the Top 25 ranked teams while fresh faces breathe new drama into some established title contests.

Duke soccer still dominating the ACC

With just one loss on the season, No. 1 Duke has dominated the college soccer field this year, outscoring opponents 53-10 to enter the postseason on a 15-match unbeaten streak.

Even more, the Blue Devils have done so in arguably the sport's toughest conference. A full seven of the country's Top-14 teams compete in the ACC.

Duke's journey to a first-ever College Cup title begins with Thursday's ACC tournament semifinals, where the Blue Devils will take on in-state rival and 21-time NCAA champs No. 8 UNC at 8 PM ET, with live coverage on ACCN.

If they can beat the Tar Heels for the third time this season, they'll face either defending national champion No. 6 Florida State or No. 3 Wake Forest in Sunday's tournament final.

SEC sees newcomers stir the college soccer pot

Like Duke in the ACC, No. 2 Mississippi State put together a historic season, scoring their highest-ever program ranking by tearing through the SEC on their way to a one-loss regular-season finish.

While the SEC isn't quite as strong as the ACC, the top teams are well matched. Mississippi State defeated all three of the other ranked teams still in the SEC tournament — No. 5 Arkansas, No. 14 South Carolina, and No. 21 Texas — though only by a single goal in each contest.

For the Bulldogs to book their first-ever conference tournament trophy, they'll first have to beat Tennessee in Tuesday's 5:30 PM ET quarterfinal, airing on the SEC Network.

Big-time turnovers rock Big Ten college soccer

Fresh faces are ruling the Big Ten tournament, where three of the four semifinalists — No. 4 USC, No. 9 UCLA, and Washington — are conference rookies. 

The former Pac-12 trio showed out this season, eclipsing traditional Big Ten powerhouses like No. 22 Penn State and 2023 title-winner No. 16 Michigan State in the race to the tournament title.

The lone conference veteran still in the mix is Rutgers, who'll take on the top-seeded Trojans for the first time this year in Thursday's 2 PM ET semifinal, before the Bruins aim to hand the Huskies a second loss at 4:30 PM ET, both airing on the Big Ten Network.

Pushing toward the NCAA championship bracket in the Big 12

The Big 12 is arguably NCAA soccer's weakest Power conference with just two ranked teams, but that doesn't mean the conference tournament is without teeth.

One of Wednesday's four semifinalists — No. 7 TCU, No. 17 Texas Tech, 2023 College Cup semifinalist BYU, or Kansas — will emerge with the Big 12 trophy and a guaranteed spot in the NCAA tournament. The other three must wait until the selection committee decides their fate on Monday, making every minute left on the pitch a vital one.

How to watch this year's NCAA soccer conference tournaments

All Power Four conference finals are set for this weekend, with the Big 12 kicking things off at 8 PM on Saturday, with live coverage on ESPN+.

Then on Sunday, the ACC and Big Ten finals begin at 12 PM ET, with the ACC airing on ESPNU and the Big Ten on the Big Ten Network.

Later, the SEC trophy will be on the line during the 2:30 PM ET final, broadcast by the SEC Network.

College basketball made its return by unleashing a blockbuster slate of games to tip off the 2024/25 NCAA season on Monday.

While fans will have to wait until Thursday for their first season look at No. 2 UConn's preseason All-American Paige Bueckers, 16 of the preseason Top 25 teams hit Monday's court, including No. 6 Notre Dame, No. 7 LSU, and No. 8 Iowa State.

Paris doubleheader tips off college basketball season in style

It all started with a ranked doubleheader in Paris, France. First, No. 3 USC squeaked by No. 20 Ole Miss 68-66 behind double-doubles from preseason All-Americans JuJu Watkins and Kiki Iriafen.

Even though USC led by 11 points after the first half, they needed both sophomore phenom Watkins's 27 points and 10 rebounds plus Stanford transfer Iriafen's 22 points and 13 rebounds to stave off the Rebels' 40-point second-half surge.

As for Ole Miss, guard KK Deans made an early season statement by leading her team with 19 points. All-SEC shooter Madison Scott put up another 14. Out of the gate, the Rebels expertly disrupted the Trojan offense, forcing USC to commit 26 turnovers in their season opener.

Later, No. 5 UCLA followed USC in bringing a season-opening win back to California. Led by star center Lauren Betts's 18-point, 12-rebound double-double, the Bruins — who committed 22 turnovers — defeated No. 17 Louisville 66-59.

Despite the loss, Louisville freshman guard Tajianna Roberts made a major splash, racking up 21 points in her college basketball debut.

Notably, the first-ever Paris NCAA basketball game was contested to open the 2023/24 season. At that time, South Carolina defeated Notre Dame, kicking off an undefeated run all the way to the 2024 NCAA Championship — a path USC and UCLA will be eager to follow after Monday's victories.

Other Monday matchups showcase NCAA basketball talent

Overseas battles aside, much of the NCAA's opening day pairings were dominated by ranked schools. Top-25 teams triumphed over lesser opponents, none more so than No. 19 Florida State's 119-49 win over North Florida.

However, the day's most intriguing ranked-unranked matchup is still to come, when No. 1 South Carolina takes on Michigan in Las Vegas.

With the exception of Chicago Sky rookie Kamilla Cardoso, the Gamecocks return every starter and most of their bench from last season's championship roster. They'll look to extend their unbeaten run into this season, starting with the Wolverines.

South Carolina women's basketball will tip off against Michigan in Las Vegas at 7:30 PM ET on Monday, with live coverage on TNT.

The 2024 NWSL Playoffs are officially set, with Portland and Bay FC clinching the final two postseason spots this weekend.

The Thorns punched their ticket with Friday's 3-0 win over Angel City thanks to a trio of first-half goals from attackers Christine Sinclair, Sophia Smith, and Morgan Weaver. The victory officially extends Sinclair's pro career by at least one more match, and saw the soccer legend notch her final goal in front of a Providence Park home crowd in her 200th regular-season game.

Then on Saturday, a brace from forward Racheal Kundananji boosted Bay FC to a 3-2 win over Houston, snagging the 2024 expansion team the postseason's No. 7 seed in the process. Even more, Bay became the winningest first-year team in NWSL history with 11 wins, surpassing 2022 expansion team San Diego's 10 victories.

Top NWSL playoff teams build postseason momentum

The top four playoff-bound teams rolled through their last regular-season matches, with Orlando, Washington, Gotham, and Kansas City securing both victories and important postseason momentum.

Notably, Shield-winners Orlando snapped their two-game skid with Saturday's 3-2 win over Seattle, giving Pride fans hope for some more 2024 hardware.

North Carolina and Chicago, however, floundered in losses. Washington striker Ashley's Hatch's 37th-minute goal was the difference-maker in North Carolina's 1-0 loss on Saturday, the Courage's first home defeat since April 2023, when they also fell to the Spirit on a Hatch game-winner.

Like the Courage, the Red Stars locked up their playoff spot weeks ago, but their 3-1 Sunday loss to KC had arguably the most potent impact on the postseason picture. The combination of Chicago's defeat and victories from Portland and Bay sent the Red Stars down to eighth place on the table, their lowest standing in the league all season.

Chawinga officially clinches NWSL Golden Boot Award

The other big weekend winner was KC's Temwa Chawinga. Chawinga officially took the 2024 Golden Boot title behind her league-record 20 goals and six assists, despite sitting out the Current's Sunday victory with a knee injury.

Also impressing from the injured list this season is Spirit rookie Croix Bethune, who finished as the year's NWSL assist leader. Before her season-ending meniscus tear in August, Bethune notched 10 assists to tie the NWSL record held by Tobin Heath.

How to watch the 2024 NWSL Playoffs

The NWSL's first-ever eight-team bracket is locked up, with the quarterfinals kicking off on Friday.

No. 1 Orlando will face No. 8 Chicago at 8 PM ET on Friday, streaming live on Prime, with No. 4 Kansas City battling No. 5 North Carolina on Saturday at 12 PM ET on CBS.

Sunday's doubleheader will air on ABC, with No. 2 Washington hosting No. 7 Bay FC at 12:30 PM ET before No. 6 Portland visits No. 3 Gotham at 3 PM ET.
