Athletes Unlimited is teaming up with Aspiration on a historic, multi-year partnership that will help the league become the first carbon-neutral sports league based in the United States.

The partnership, which runs through 2023, will begin with the inaugural Athletes Unlimited Basketball season in January and continue through AU’s volleyball, lacrosse and softball seasons. Aspiration, a sustainability service solution for consumers and companies, had previously sponsored AU Softball in 2020 and 2021.

“Aspiration is a perfect partner for Athletes Unlimited and we couldn’t be more pleased to expand their presence in our community,” Athletes Unlimited CEO Jon Patricof said in a release. “Our innovative mindsets and core values are precisely aligned, highlighted by a deep-seated commitment to growing our leagues, investing in our athletes and bettering the world around us. Social responsibility is one of the foundations on which Athletes Unlimited was built, and Aspiration’s expertise will help advise and guide us on how we can minimize our environmental impact.”

The goal of the partnership is to implement sustainability into the day-to-day operations of the league and different athlete and fan experiences.

For the first time in Athletes Unlimited history, jersey sponsorship is included in the partnership. For the next two seasons, basketball and volleyball uniforms will feature Aspiration patches. AU will also feature physical and digital signage elements and activations to help promote sustainability across AU’s four leagues.

In collaboration with the league’s media partners, Aspiration will become the presenting partner of five national broadcasts for each of the four leagues every season.

“This partnership is a testament to the continued growth and traction of the fast-growing sector of women’s pro sports, as well as the power of building complementary leagues across four sports, a network of national TV and digital partners, and robust fan engagement platforms,” Patricof said. “Aspiration is joining a growing group of like-minded partners that see the incredible opportunity ahead of us, and know we are just getting started.”

AU will also introduce new campaigns in 2022, alongside The Aspiration Difference programming, that will be unique to every sports league. For example, AU Basketball will incorporate “Trees for Threes,” committing to plant 10 trees for every successful 3-pointer. As part of the “Round the Bases” campaign in softball, 100 trees will be planted for every run scored. The partners are still developing campaigns for volleyball and lacrosse.

Athletes Unlimited will also incorporate Aspiration’s “Planet Protection” program into every ticket sold, contributing to funding carbon removal projects around the world.

Currently, Aspiration is evaluating Athletes Unlimited’s carbon footprint through a comprehensive assessment. Upon its conclusion, AU will work with the company to outline goals for long-term sustainability as well as adequate vision and strategies.

“Teaming up with Athletes Unlimited, a game changer in the sports industry, feels like the perfect fit,” said Aspiration CEO Andre Cherny. “We both are founded on values of conscience and concern for people and the planet. We couldn’t be more excited for the opportunity to share the deep understanding we have when it comes to sustainability, and how we can continue expanding this partnership with Athletes Unlimited.”

Led by undefeated overall No. 1-seed Nebraska, the college volleyball elite will begin their quest for the 2025 national championship on Thursday, when the first round of the 64-team NCAA Division I tournament hits courts nationwide.

The Huskers are still chasing a perfect season, entering the 2025 title hunt on a 30-0 run having dropped just six sets all season — including losing just one set since September 16th.

"I was expecting us to be great, but certainly not undefeated," said Nebraska alumna and first-year Cornhusker head coach Dani Busboom Kelly on a recent episode of the Welcome to the Party podcast. "They continue to exceed our expectations."

Busboom Kelly's roster is loaded with the kind of experienced connection that only comes when the core of players have competed together for three straight seasons — an increasing rarity in the transfer portal and NIL era.

That said, this core has unfinished business on the national stage, with the superstar junior trio of middle blocker Andi Jackson, outside hitter Harper Murray, and setter Bergen Reilly — all AVCA Player of the Year semifinalists — looking to bring the first NCAA trophy in eight years back to Lincoln.

"It's such a special row, because we just know that all of us have been through thick and thin together and our bond is so strong," Jackson told USA Today Sports earlier this week. "[And Busboom Kelly] gives us so much confidence and we know that with her as our coach, we just can play fearless."

Stacked tournament field looks to spoil Nebraska's season

Even with their "fearless" play, a host of stellar opponents await Nebraska in the NCAA tournament gauntlet, hoping to play spoiler — including Busboom Kelly's previous program, the Louisville Cardinals, who await the Cornhuskers as the No. 2-seed in their own regional quadrant.

Fellow No. 1 seeds Texas, Kentucky, and Pitt will also chase their eventual chance at the Huskers via their own regionals, where the Longhorns could see arguably the stiffest competition from both No. 2-seed Stanford — the winningest program in NCAA volleyball history — and defending champion and No. 8-seed Penn State.

With tickets to the 2025 Final Four in Kansas City on the line, the NCAA volleyball bracket's 64 squads will start serving at 16 campus sites on Thursday.

How to watch the first round of the 2025 NCAA volleyball tournament

This year's NCAA volleyball finale begins when No. 5-seed Colorado takes on unseeded American University at 3 PM ET on Thursday, kicking off a two-day first round of 32 matches — with No. 1 Nebraska looking to handle Long Island University in their initial tournament tilt at 8 PM ET on Friday.

All games in the early rounds of the 2025 Division I tournament will air live on ESPN+.

US tennis star Coco Gauff continues to win off the court, with the 2025 French Open champion topping Sportico's list of the 15 Highest-Paid Female Athletes for the third consecutive year.

Fueled by $23 million in off-court endorsements, the $31 million earned by the 21-year-old world No. 3 WTA player edged out the $30 million total income that fellow tennis star and world No. 1 Aryna Sabalenka garnered in 2025.

Unsurprisingly, a full 10 athletes on the Sportico Top 15 list are tennis stars, a direct result of the fact that all four Grand Slams and the Masters 1000 tournaments boast equal prize money between the men's and women's competitions — a shift that began with the 1973 US Open.

That established expectation of gender equity in prize money has tennis far outpacing salaries in most other women's sports.

Also making the Top 15 are two LPGA golfers — world No. 1 Jeeno Thitikul (No. 15 on the Highest-Paid Female Athletes list) and US star No. 2 Nelly Korda (No. 7) — as well as popular Olympic skiier Eileen Gu (No. 4), WNBA superstar Caitlin Clark (No. 6), and USA gymnastics legend Simone Biles (No. 11).

Notably, Gu, Clark, and Biles as well as Venus Williams (No. 14) all proved the power of endorsements on this year's list, with nearly all of the quartet's earnings coming from sponsorship deals.

As WNBA CBA negotiations rage on, revenue sharing continues to be a wedge issue for both sides of the table, with the league office and the WNBPA eyeing the terms of the most recent proposal from differing viewpoints.

The Athletic reported on Wednesday that the WNBA believes it has offered the revenue-sharing salary model that the players have pushed for throughout the CBA talks, leaving athletes to claim 50% of the "sharable" portion of league revenue.

How the WNBA will determine the "sharable" cut is uncertain, though sources claim the compensation structure on offer will result in players taking home less than 15% of the league's total earnings.

That percentage is likely to take a further hit over the lifetime of a new CBA, according to the league's multi-year earning projections.

"I don't feel like there's any cultivation of a culture of trust [in the CBA talks]," WNBPA president and Seattle Storm star Nneka Ogwumike told The Athletic. "I feel like we've been heard, but not listened to, and I'm hoping that that changes in this 40-day extension, because what we want to do is get a good deal done."

Parental leave, draft combine, and more enters the WNBA CBA talks

Along with the issue of revenue sharing, the latest WNBA offer also reportedly outlined other proposals, such as the institution of a required offseason draft combine, the elimination of team housing, and the possible extension of the competition calendar by starting earlier and/or finishing the season later.

As for the WNBPA's Tuesday counteroffer, the players union is seeking to eliminate the core designation and shorten the current four-year rookie contract to three years.

The WNBPA is also asking to add non-birthing parental leave, retirement benefits, and reimbursements for mental healthcare.

The WNBA and WNBPA will meet again to negotiate sometime this week, with talks racing toward the second-extension deadline of January 9th, 2026.

After setting a new NCAA basketball record by scoring 100+ points in eight consecutive games, the No. 5 LSU Tigers will face their season's first true test when they visit the preseason-No. 7 Duke Blue Devils as part of the 2025 ACC/SEC Challenge on Thursday night.

"We don't play nobody in our nonconference schedule," senior guard Flau'jae Johnson told JWS in November. "From December on out, that's when it gets really [exciting]."

With their history-making string of lopsided wins under their belt, the Tigers will try to keep the streak alive against a now-unranked Duke side on a three-game losing skid.

The Blue Devils will rely on leading scorer and rebounder Toby Fournier for a spark, with the sophomore forward averaging 15.8 points per game despite Duke's 3-5 start.

As for LSU, the title-hunting Tigers will look to stat undefeated behind Johnson's team-leading 17.0 scoring average, as well as the 16.1 points per game put up by junior star transfer MiLaysia Fulwiley.

"Ballers just want to ball, like hoopers just want to hoop," Johnson said of LSU's quick cohesion this season. "You find different ways to bond and gel with teammates."

How to watch LSU vs. Duke on Thursday

Duke will host No. 5 LSU in the 2025 ACC/SEC Challenge at 9 PM ET, with live coverage airing on ESPN.
