A weekend of nonstop NCAA basketball starts now, as the nation's top teams across the ACC, Big 12, Big Ten, and SEC take the court to tip off their battles for Sunday's conference tournament crowns.

After earning early-round byes due to their elite regular-season records, No. 1 Texas, No. 2 USC, No. 4 UCLA, No. 5 South Carolina, and other Top 10 teams will tackle their first postseason games on Friday afternoon.

Beginning play in their respective tournaments' quarterfinals round comes after days of back-to-back competition between lower seeds, meaning Friday's matchups could pit top team's week-long rest against the momentum of potential Cinderella squads like Big Ten No. 11-seed Iowa.

Despite posting a mediocre 10-8 regular-season conference record, the unranked Hawkeyes are currently playing their best basketball of the season, allowing them to confidently advance through the Big Ten tournament’s first two rounds.

After dominating No. 14-seed Wisconsin on Wednesday and upsetting No. 6-seed Michigan State on Thursday, the three-time defending Big Ten tournament champs will face a Friday quarterfinal date with No. 3-seed Ohio State — the nation's No. 13-ranked team.

Rivalry revenge takes center court at conference tournaments

Friday's action is also primed to set the stage for potential high-stakes rematches between regular-season rivals later this weekend.

In the SEC, Saturday's semifinals could see No. 2-seed Texas meet No. 3-seed LSU, with the No. 9-ranked Tigers looking to avenge their February loss to the nation's top-ranked team.

Meanwhile, Sunday afternoon's Power Four finales could be a revenge fest, as teams who either shared or narrowly missed their league's 2024/25 conference titles will potentially face off against the regular-season trophy-winners.

In both the Big Ten and Big 12, the No. 2 seeds — UCLA and Baylor, respectively — could be hunting a season-first victory over No. 1 seeds USC and TCU in their tournament finals.

After splitting the regular-season ACC title with NC State, who claimed the tournament's No. 1-seed thanks to their head-to-head defeat of the Irish, No. 2-seed Notre Dame could have a shot at redemption against the Wolfpack on Sunday.

Similarly, if they make Sunday's game, the Longhorns will aim to humble co-SEC champion South Carolina after the Gamecocks grabbed the tournament's top seed thanks to a coin flip.

This weekend, however, it's not just redemption and hardware on the line. Conference tournament champions will also snag the ultimate prize: automatic entry into March Madness.

Those who fall short will still be fighting tooth and nail to impress the NCAA basketball committee with Selection Sunday looming on March 16th.

Seeking a Cinderella run to a record-breaking fourth Big Ten tournament title, No. 11-seed Iowa's Friday game against No. 3-seed Ohio State is arguably the quarterfinal with the most upset potential. The Hawkeyes and Buckeyes will tip off at 9 PM ET, airing live on BTN.

Should they both advance from their Friday quarterfinals, No. 2-seed Texas's Saturday game against No. 3-seed LSU will be the weekend's can't-miss semifinal, which is set for 7 PM ET on ESPN2.

Sunday will see all Power Four conferences crown their champions. ESPN will showcase three finals, airing the ACC at 1 PM ET, the SEC at 3 PM ET, and the Big 12 at 5 PM ET.

Meanwhile, Sunday's 4:30 PM ET Big Ten tournament championship game will air live on CBS.

Chelsea FC is once again looking across the pond to bolster their roster, with the six-time reigning WSL champions reportedly aiming to make a deal with NWSL side Angel City to acquire ACFC and USWNT forward Alyssa Thompson, per The Guardian this week.

Though the two clubs have yet to reach terms, Chelsea would need to have the deal signed before the WSL transfer window closes next Thursday.

Any agreement for Chelsea to snag Thompson from Angel City will likely feature yet another historic transfer fee, with cost projections topping former Tigres UANL star Lizbeth Ovalle's record $1.5 million transfer to the Orlando Pride earlier this month.

The 20-year-old phenom is currently under contract with ACFC through the 2028 season after inking a three-year extension this past January.

With six goals and two assists in her 16 regular-season appearances in 2025 so far, the 2023 NWSL Draft No. 1 pick is trailing only rookie Riley Tiernan's seven goals on this year's Angel City scoresheet.

Should the transfer go through, Thompson would be the third ACFC player in a week to be moving to the UK, with the NWSL club transferring defender Alanna Kennedy and midfielder Katie Zelem to the newly WSL-promoted London City Lionesses on Wednesday.

As for Chelsea, the Blues have been a major player in recruiting US players over the last few seasons, with Thompson potentially joining her USWNT teammates Catarina Macario and Naomi Girma in suiting up for the WSL side's upcoming 2025/26 season.

Two-time US Open champion Naomi Osaka is looking like her old self this week, as the world No. 24 advanced to the 2025 New York Grand Slam's third round for the first time since 2021 with a straight-set win over the US's No. 47 Hailey Baptiste on Thursday.

"I don't make it my business to know anymore, I kind of just leave it up in the air," said the fan favorite following questions about a possible fifth Grand Slam title run. "I've trained really hard. I practiced really hard. If it happens, it happens."

After taking her lumps on the WTA Tour since returning from pregnancy in 2024, the 2025 US Open marks Osaka's first seeded entry into a major tournament since 2022 — and she appears to be embracing her competitive boost in style, complete with eye-catching outfits and a matching Labubu.

The 27-year-old Japanese national next faces No. 18 Daria Kasatkina in the pair's third career meeting, with Osaka getting the best of the Australian in both previous matchups — most recently at the 2024 Italian Open.

Should Osaka advance to Sunday's Round of 16, she could be on a collision course toward a date with No. 3 Coco Gauff, after the US star advanced past her own emotionally challenging second-round battle on Thursday.

With times still to be announced, Osaka will next battle Kasatkina during the second day of 2025 US Open third-round play on Saturday.

The No. 1 Kansas City Current have been unstoppable this season, riding a 10-match unbeaten streak into Saturday's game against the No. 9 North Carolina Courage and inching closer to claiming a franchise-first NWSL Shield.

The Current's dominant 12-point advantage over the No. 2 Washington Spirit marks the league's largest top-table margin since the Courage finished 15 points ahead in 2018.

Even more, Kansas City tops the NWSL in goals scored (34) while also registering the fewest goals allowed (10), entering the league's 18th weekend of play with a record-tying five consecutive shutouts.

After coming in fourth in 2024, the Current's defense has continued to improve under manager Vlatko Andonovski, while another MVP-level year from star forward Temwa Chawinga has bolstered Kansas City's offense.

Chawinga currently leads the 2025 NWSL Golden Boot race with 11 goals through 17 games, while sitting in the league's Top 3 for both shots and shots on goal.

"I think because we have such a powerful offense, the defensive things, maybe people don't notice as much," Kansas City forward Michelle Cooper said earlier this week. "I think something absolutely important to us is our entire back line and the commitment to get little touches in, to take [advantage] of angles, and block shots."

No. 1 Kansas City will host No. 9 North Carolina — one of just two teams to defeat the Current all season — at 7:30 PM ET on Saturday, with live coverage airing on ION.

The No. 5 New York Liberty are creeping back up the ladder, as the defending WNBA champions continued reversing their recent skid with Thursday's 89-63 win over the No. 10 Washington Mystics — all while the race to the 2025 WNBA Playoffs reaches its boiling point.

While Washington rookie Sonia Citron's 18 points led the game, New York pulled together a true team effort to secure Thursday's victory, with five Liberty players scoring double-digits — including a season-high 16 points off the bench from forward Isabelle Harrison in her return from concussion protocol.

"We're not looking at the other teams at this point," Liberty forward Emma Meesseman said after the game. "We're just looking at ourselves, to maybe send a message to ourselves."

Despite that focus, New York is still contending with injury woes that have overshadowed much of the Liberty's season, taking Thursday's court without starters Sabrina Ionescu (toe), Jonquel Jones (illness), and Natasha Cloud (nose), while leaning on recently returned forward Breanna Stewart.

"We need to win the rest of our games," acknowledged Stewart, with the team gearing up for visits to the No. 4 Phoenix Mercury, No. 8 Golden State Valkyries, and No. 7 Seattle Storm over the next week. "We need to go and be road warriors."

The Liberty will have their hands full against the Mercury this weekend, with Phoenix coming in hot off a three-game winning streak with postseason-clinching top-of-mind.

"It's like a playoff matchup," Stewart added. "It's a big game, big implications, and [we're] not shying away from that."
