At least two of the nation's best NCAA basketball teams will see their undefeated 2024/25 campaigns end this weekend, when a pair of cutthroat college clashes tests the limits of four championship contenders.

First, No. 6 Notre Dame will visit No. 3 USC on Saturday, before No. 1 South Carolina takes on the Trojans’ crosstown rival No. 5 UCLA on Sunday.

Saturday's NCAA showdown features superstar sophomores

All eyes will be on preseason All-American sophomore guards JuJu Watkins and Hannah Hidalgo when the Irish contend with their season's first ranked opponent on Saturday.

Already a phenom, Watkins became the fastest Trojan to 1,000 career points last Friday — and she did it by a mile. The previous record-holder, legend Cheryl Miller, needed 48 games to hit the same mark.

As for Hidalgo, she's already hit the century mark across Notre Dame’s four matchups to average 25 points per game — the fifth-best offensive rate in the country.

The Irish's other secret weapon, guard Olivia Miles, is also back, returning from her February 2023 ACL tear with a vengeance in the Irish's season opener. Already averaging 18.3 points per game, Miles has also banked 27 assists over Notre Dame's four games — more than twice that of any of her teammates.

Between Hildago and Miles, plus ND's admittedly lopsided matchups so far, the South Bend squad has blasted their opponents by a 42.5-point average scoring margin this season.

It's a similar story for USC, who have been on a tear since their narrow 68-66 season-opening win over then-No. 20 Ole Miss. The Trojans thrashed their next three opponents by outscoring them by a gobsmacking average of 57 points.

The Trojans will need all that offense, plus the stylings of Watkins and All-American forward Kiki Iriafen, to handle the Irish on Saturday. Notre Dame holds the 8-2 all-time series advantage between the two teams, though they haven't squared off since 2011. Should USC emerge victorious, it will be their first win over the Irish since 2006.

Sunday puts powerhouses in the paint

The subsequent Sunday battle between UCLA and South Carolina — who set a program-record 43-game win streak on Wednesday — will likely be decided in the paint, where both team's superstars thrive.

The Gamecocks' depth keeps their stat sheet fairly balanced, making junior forward Chloe Kitts’s team-leading rates in scoring and rebounding that much more impressive.

That said, her UCLA counterpart, junior center Lauren Betts, has been dominant. By averaging a double-double across the Bruins' four tilts with 21.5 points and 11.5 rebounds per game, Betts is already sparking National Player of the Year commentary.

Both squads began their 2024/25 campaigns with tight wins, but while UCLA's came over then-No. 17 Louisville, South Carolina was nearly shocked by unranked Michigan. On the other hand, the Gamecocks are the only team to have handled a Top-10 opponent so far this season, confidently downing then-No. 9 NC State just six days after their near-disaster with the Wolverines.

Sunday's showdown kicks off a gauntlet of four ranked matchups in five games for South Carolina. Even though UCLA haven't defeated the Gamecocks this century, the Bruins are the biggest challenge to the reigning champions' undefeated streak on their 2024 docket.

Depending on which version of South Carolina shows up, a combination of the bigs and each team's overall consistency will likely determine Sunday's victor.

The host of the 2022 Men's World Cup is back in the headlines, with Middle East nation Qatar reportedly in talks with FIFA to house the inaugural Women's Club World Cup in January 2028.

Despite recent gains on the men's side, the Qatar women’s national team is currently unranked due to a lack of official matches — founded in 2009, the squad has not competed in any official capacity in 12 years.

The lack of support for the nation's women's team is unsurprising given Qatar's concerning human rights record — one that the soccer world has long called into question, particularly concerning the treatment of women, migrants, and the LGBTQIA+ population.

The reported aim to host the 2028 Women's Club World Cup would constitute another example of Qatar sportswashing those international human rights concerns using the country's close relationship with the international soccer governing body — one bolstered by the fact that FIFA president Gianni Infantino resides in the Qatari capital, Doha.

Despite this week's reports, FIFA said they have yet to receive a formal bid for its first-ever women's club competition.

With 16 teams expected to compete from January 5th through 30th, 2028, European clubs are already bracing for calendar disruptions thanks to the Women's Club World Cup's winter kick-off.

At least five teams from Europe and two each from Asia, Africa, South America, and North America will compete, with the remaining three clubs determined by a 2027 qualifying tournament.

US Figure Skating is hoping to make Olympic history this year, naming powerhouse trio Alysa Liu, Amber Glenn, and Isabeau Levito to the official 2026 Winter Games roster on Sunday as Team USA aims to end a 20-year medal drought in Milan next month.

Glenn earned her spot after winning her third-straight national title on Friday, with reigning world champion Liu and 18-year-old 2024 Worlds runner-up Levito chasing her onto the 2026 US Figure Skating Championships podium.

"Just so grateful. That was terrifying," Glenn said after her win. "And I had to skate after two incredible ladies brought down the house."

Liu is the only US women's singles skater returning with Olympic experience — at just 16 years old, she took sixth place in Beijing — but the group's national podium tally adds to Team USA's renewed confidence.

"All we've got to do, is do our job," said 26-year-old Glenn. "I think the US ladies have come so, so far in the last two decades that if all three of us do our jobs in Milan, then more than likely someone's going to be up there [on the Olympic podium]."

While the US women will first take the ice in the team competition on February 6th and 8th, the trio will begin contending for individual glory by skating their short programs at 12:45 PM ET on February 17th, airing live on USA Network.

The 2026 Olympic podium will then be finalized in the free skate competition at 1 PM ET on February 19th, with live coverage on NBC.

Incoming Denver Summit FC rookie Jasmine Aikey capped her Stanford career by earning the top honor in NCAA women's soccer, lifting the 2025 MAC Hermann Trophy last Friday.

Aikey is now the sixth Cardinal to win the award, joining fellow alums and USWNT standouts like Kelley O'Hara (2009), Christen Press (2010), Catarina Macario (2018, 2019), and Andi Sullivan (2017).

"I am so happy that Jasmine's hard work and dedication paid off, as she is one of the most talented and competitive student-athletes I have ever coached," said Stanford head coach Paul Ratcliffe in the school's Friday announcement.

The 20-year-old topped both Stanford and the ACC in goals scored this season with 21, tallying 11 assists as she led the Cardinal to both the 2025 ACC Championship and last month's College Cup Final.

Even more, her dominant season saw Aikey claim the 2025 MAC Hermann Award over fellow finalists and ACC stars Jordynn Dudley, a junior forward for reigning NCAA champion Florida State, and Izzy Engle, a Notre Dame sophomore attacker and the 2025 ACC Offensive Player of the Year.

With her Friday win, Aikey also made history as just the second student-athlete to win both the Hermann Trophy and the Academic All-America Team Member of the Year, joining Portland alum and international soccer's all-time leading scorer, Canada legend Christine Sinclair.

The forward won't be resting on her laurels for long, however, with Aikey now gearing up for next month's NWSL preseason after signing a two-year deal to join 2026 expansion side Denver Summit last Thursday.

"I'm ready to get to work and help set the standard in Denver," remarked the newly minted pro in a club statement.

As top tennis talents turn toward the 2026 Australian Open, this week's WTA rankings refresh hints at the drama to come as the year's first Grand Slam nears.

Following her strong 2026 United Cup showing against world No. 2 Iga Świątek, Team USA favorite Coco Gauff jumped to No. 3, leapfrogging fellow US star No. 4 Amanda Anisimova along the way.

Meanwhile, reigning Australian Open champion Madison Keys hit a slight skid, falling two spots to No. 9 after unwavering No. 1 Aryna Sabalenka ousted her from last week's Brisbane Open quarterfinals.

Sabalenka aside, Switzerland's No. 10 Belinda Bencic might have the hottest hand heading into Melbourne, busting into the Top 10 after winning all five of her 2026 United Cup singles matches — including a dominant three-set victory over Poland's Świątek.

Bencic also made history in this week's rankings update, becoming the first returning mother to crack the WTA's top tier since US tennis icon Serena Williams did so in 2021.

"I think it's been a huge goal, maybe a huge ride after the whole comeback, to come back and prove this to myself, that it's possible," Bencic said this week.
