Thursday's 2024 NCAA volleyball semifinals aren’t just an all-No. 1 seed affair, they also pit conference rivals against each other on the sport’s biggest stage.

With one all-ACC and one all-Big Ten semifinal on deck, the sport's top conferences are poised to face off in Sunday's championship game. But while the Big Ten will look to add another piece of hardware to its deep volleyball trophy case, the ACC is aiming to snag their first-ever NCAA title in the sport.

The ACC teams hunting history

Thursday's first match features Pitt against Louisville, as each looks to become the ACC's first national volleyball champion. Both rivals have been knocking on the door of NCAA glory in recent years, with the Panthers falling in the last three national semifinals, while Louisville advanced to the Final Four in 2021 and became the conference's first-ever finalist in 2022.

Notably, this will be the third straight year that the ACC rivals have met in the tournament. The Cardinals took down Pitt 3-2 in their 2022 semifinal, while the Panthers ousted Louisville with a reverse sweep in last year's Regional final.

Both squads have been Top-5 teams all season, led by some of the country's top players. Pitt sophomore Olivia Babcock's service aces and kills rates topped the ACC this year, earning her the conference's Player of the Year award. Babcock shifted into an even higher gear in the postseason, setting an NCAA tournament record with her 31 kills against Oregon in the Panther's Regional semifinal.

Veteran outside hitter Anna DeBeer continues to be Louisville's workhorse, leading the Cardinals on their Regional stat sheet after a season in which the grad student crossed the 1,000 mark in both career kills and digs.

With the Final Four set in Louisville, the Cardinals have already won the home-court advantage lottery entering Thursday's semifinal. That said, for a chance at earning a national championship in front of their fans, Louisville will need to survive this year's overall top team — a Pitt squad who've already taken down the Cards twice this season.

The Big Ten's perennial contenders

Boasting 32 semifinal appearances and 21 championship matches resulting in 12 national titles between them, Big Ten rivals Penn State and Nebraska will put their deep Final Four experience to the test against each other in Thursday's nightcap.

Nebraska has been near-perfect all tournament, dropping just one set, while Penn State has lost four — the most of any of the semifinalists.

The Nittany Lions, however, had the Huskers' number in the regular season, handing Nebraska their only conference loss all year and snapping their 25-match win streak in the process.

To again humble the Huskers, Penn State will need a repeat of their November block party that stifled Nebraska's offense, all while continuing their own attack, led by outside hitter Jess Mruzik. The grad student is on a postseason hot streak, coming in clutch by hammering at least 20 kills per match over Penn State's last three contests.

Nebraska, who didn't have a single senior on last year's roster, returned nearly all of their 2023 superstar team. Outside hitters Merritt Beason and Harper Murray fuel a relentless Cornhusker attack, while Nebraska's defense thrives behind libero Lexi Rodriguez — one of the four 2024 AVCA Player of the Year finalists.

Both Nebraska and Penn State will take Thursday's court with redemption on their minds. The Huskers are hungry to finish the job after being swept by Texas in last year's final. Penn State, on the other hand, are seeking a return to the mountaintop in their first semifinal appearance since 2017, when they fell to eventual champions Nebraska.

How to watch the 2024 NCAA volleyball Final Four

Pitt and Louisville will kick off Thursday's NCAA semifinal action in an all-ACC battle at 6:30 PM ET, with Nebraska and Penn State’s Big Ten dual set to start 30 minutes after the first match ends. Both matches will air live on ESPN.

The guaranteed ACC vs. Big Ten national championship match is set for 3 PM ET on Sunday, with live coverage on ABC.

Two key upsets headlined Thursday's WNBA bill, sending the Phoenix Mercury soaring into third place in the league standings while the No. 6 Golden State Valkyries continued to outwit opponents.

The red-hot Mercury snagged their fourth straight win by taking down the No. 2 New York Liberty 89-81 on Thursday night, overcoming an 35-point performance from two-time MVP Breanna Stewart with five double-digit Phoenix scorers.

Meanwhile out West, the Valkyries stifled a surging No. 7 Fever, downing Indiana 88-77 in part by holding star guard Caitlin Clark to just 3-for-14 from the field — and 0-for-7 from behind the arc.

"We were being disruptive, we know that she doesn't like physicality, we know that she wants to get to that left step-back," Golden State head coach Natalie Nakase said about the Valkyries' strategy to effectively contain Clark.

Though the No. 1 Minnesota Lynx and 2024 WNBA champions New York still hold court atop the table, Thursday's actions proves that other squads are making some unexpected in-roads.

Putting together an impressive road record are the Mercury, who will ride a 4-2 away record into their Saturday matchup against the No. 11 Chicago Sky — the last stop on a four-game road trip that's been perfect for Phoenix thus far.

Already flipping the script on expectations is Golden State, with the 2025 expansion team rising despite relying on a hodgepodge roster as several players compete at EuroBasket 2025. The Valkyries will aim to keep their winning momentum in their Sunday clash with the No. 12 Connecticut Sun.

How to watch the Mercury, Valkyries this weekend

Both of Thursday's victors will be back in action this weekend, with Phoenix facing Chicago at 1 PM ET on Saturday, airing live on ABC.

Then on Sunday, Golden State will host Connecticut at 8:30 PM ET, with live coverage on WNBA League Pass.

In another weekend full of WNBA action, all eyes are on Las Vegas, as the No. 8 Aces will try to curb a two-game losing streak against two formidable opponents.

A successful weekend for Las Vegas could hinge on three-time WNBA MVP A'ja Wilson's potential return from injury, with the star forward recently upgraded to "questionable" after landing in concussion protocol last week.

Overall, the margin for error has narrowed in the middle of the WNBA pack, as talented teams continue to translate quality performances into consistency.

• No. 5 Seattle Storm vs. No. 8 Las Vegas Aces, Friday at 10 PM ET (ION): The Aces will try to end their free fall in Friday's head-to-head battle with a Seattle side that can beat anybody at their best.

• No. 7 Indiana Fever vs. No. 8 Las Vegas Aces, Sunday at 3 PM ET (ESPN): Las Vegas next faces a Fever team still smarting from Thursday's away loss to the Golden State Valkyries, with both teams narrowly clinging to positions above the playoff line.

• No. 2 New York Liberty vs. No. 5 Seattle Storm, Sunday at 7 PM ET (WNBA League Pass): The Liberty have a comfortable hold on second place, but with two losses in their last three games, New York is flirting with danger entering their Sunday game with Seattle — particularly if star big Jonquel Jones is out after suffering a knock to the ankle on Thursday.

Ultimately, there's no rest for the weary in the WNBA, as a series of difficult matchups can see a single error quickly slide into a losing streak.

The final NWSL weekend heading into the league's six-week summer break has arrived, giving teams one more chance to prove themselves before regular-season play pauses to make way for major international tournaments.

With a five-point gap separating No. 1 Kansas City from No. 2 Orlando in the NWSL standings, the Current will enter the break as the 2025 Shield frontrunners regardless of this weekend's results.

Despite Kansas City's grip atop the table, there's still plenty of room for movement both above and below the postseason cutoff line, as clubs across the NWSL look to wrap their midseason finales on a high note:

• No. 1 Kansas City Current vs. No. 10 Angel City FC, Friday at 8 PM ET (Prime): Angel City has a shot at launching themselves above the cutoff line on Friday, but they'll have to snap the Current's five-game winning streak to make it happen.

• No. 8 Gotham FC vs. No. 9 Bay FC, Saturday at 7:30 PM ET (ION): Gotham and Bay FC enter the weekend tied on points while staring at each other from on opposite sides of the playoff line — meaning a Saturday win for either club could set the tone for the rest of the 2025 season.

• No. 3 San Diego Wave FC vs. No. 4 Washington Spirit, Sunday at 10 PM ET (CBS Sports): The weekend's only top-table clash could see San Diego sprint back into second place — unless Washington leapfrogs the upstart Wave to claim the third-place spot.

The LPGA Tour has turned its attention to Texas, with the 2025 KPMG Women's PGA Championship — the third major of the pro golf season — teeing off in Frisco to a flurry of first-round action on Thursday.

All of the sport's Top 100 athletes are participating in this week's event, including No. 1 Nelly Korda, who sits in a 14th-place tie with an even-par first-round performance, and surging US dark horse No. 50 Lexi Thompson, who tied for 10th in her Thursday return from a brief retirement.

However, leading the pack heading into Friday's second round is Thailand's world No. 2 Jeeno Thitikul, who finished the first day of competition atop the leaderboard with a score of 4-under-par.

Australia's No. 24 Minjee Lee also posted a strong start, capping Thursday at 3-under to sit in second place.

While the sport's best chase victory on the links, the 2025 KPMG Women's PGA Championship is already making history off the green.

Not only is it the first-ever women's major to tee off at Frisco's Fields Ranch East, the tournament also increased its purse to $12 million on Tuesday — nearly tripling the $4.5 million prize pool from just four years ago and tying the US Women's Open for the LPGA Tour's highest payout in the process.

The third LPGA Grand Slam of 2025 continues through Sunday.

Friday's second round will air live on the Golf Channel, while coverage of Saturday and Sunday's final rounds will air across NBC and Peacock.
