Tennis's first Grand Slam of 2025 kicks off on Saturday, with the sport's heaviest hitters convening in Melbourne for the Australian Open.

World No. 1 Aryna Sabalenka — the reigning back-to-back Australian Open champion — enters as the tournament's first overall seed for the first time. However, she'll see stiff competition by way of No. 2 Iga Świątek, No. 3 Coco Gauff, and No. 4 Jasmine Paolini.

"For me being the one to chase... I like that feeling," Sabalenka told reporters this morning. "That's what drives me and helps me to stay motivated because I know that I have a target on my back."

Tough roads to the trophy litter Australian Open draw

Each top contender faces a tricky tournament draw, with upset potential lurking in every quadrant.

Sabalenka could meet 2024 Olympic gold medalist and WTA Finals runner-up No. 5 Zheng Qinwen as early as the quarterfinals, as long as she survives a first-round matchup against 2017 US Open winner Sloane Stephens.

Reigning WTA Finals champion Gauff's quadrant is in Sabalenka's half of the field, setting up a possible rematch of last year's semifinal. As for the 20-year-old US star's path, earlier rounds could see Gauff contending with tough competitors like 2021 Australian Open champ Naomi Osaka, 2024 US Open semifinalist Karolína Muchová, and 2024 US Open finalist No. 7 Jessica Pegula.

Świątek and Paolini could also meet in a semifinal, though fellow top competitors No. 8 Emma Navarro and 2020 Australian Open winner Ons Jabeur stand in Świątek's way while No. 10 Danielle Collins and 2022 Wimbledon champion No. 6 Elena Rybakina have been drawn into Paolini's quadrant.

How to watch the 2025 Australian Open

The 2025 Australian Open's first round starts on Saturday at 7 PM ET, with Sabalenka's first-round match set for 3 AM ET on Sunday.

Live coverage for the tournament will air across ESPN platforms.

The 2025 WNBA preseason continued on Tuesday, as teams size up their rosters with less than 10 days to go until the regular season tips off.

After missing the playoffs last year, the Chicago Sky is showing out under new head coach Tyler Marsh, complementing their weekend win over Brazil with a 74-69 victory against 2024 championship contenders Minnesota on Tuesday.

The Sky successfully leaned into their young core, pairing second-year bigs Angel Reese and Kamilla Cardoso with new backcourt talent like rookie Hailey Van Lith. Also lifting Chicago this season are veteran leaders Ariel Atkins and Courtney Vandersloot.

"Hailey is great, she's like a sponge," Vandersloot said after Tuesday's game. "She's listened to everything I say. I think the best part of it is that we can compete in practice — we're going to make each other better."

With Tuesday's win, the Sky join the Indiana Fever and Las Vegas Aces in winning both of their 2025 WNBA preseason matchups so far, with Chicago forecasting quite the turnaround from last year's losing record.

"We understand that nothing that's happened in the past, good or bad, impacts what we're doing moving forward — and that's with any team," Marsh told reporters this week.

After a quietly active offseason and several key draft picks, the 2025 WNBA season could see the Sky right the ship — as long as Chicago keeps striking a balance between their young firepower and seasoned leaders.

Five-time Olympic gold medalist Sue Bird is taking over as managing director for the USA women's basketball team, per multiple reports on Tuesday.

Bird will move into the key leadership position with Team USA in the lead-up to the 2028 LA Olympics, where the women's side will shoot for a record-ninth consecutive gold medal.

The legendary point guard's hiring is a significant departure for USA Basketball, with the 44-year-old now responsible for selecting the team's players and coaches.

Until now, Team USA relied on an Olympic committee to oversee roster decisions and build national team camps. The decision to institute a managing director, however, will shift the women's program to mirror the leadership structure that the men's side first implemented in 2005.

Bird's first major test at the helm will be next year's FIBA World Cup, which tips off in Germany in September 2026.

That said, the work toward that international title will begin with World Cup qualifying this coming November, when national teams will hit the court immediately after the WNBA wraps up its 2025 postseason play.

The selection and evaluation committee for USA Basketball never shied away from difficult decisions, but this week's switch to a single-entity structure will put Bird directly on the hook for the program's success — with an Olympic record streak on the line.

The US Olympic and Paralympic Hall of Fame announced their Class of 2025 on Tuesday, with this year's iconic cohort headlined by tennis titan Serena Williams and track legend Allyson Felix.

Alongside four-time Olympic gold medalist Williams and seven-time gold medalist Felix — the most decorated woman in Olympic track and field history with 11 total medals — four other women and one women's team snagged spots in the 2025 class.

Joining the pair are gymnastics icon Gabby Douglas, a two-time team gold medalist and the first Black woman to take individual all-around gold in Olympic history, and three-time beach volleyball gold medalist Kerri Walsh Jennings.

Additional inductees include the gold medal-winning 2004 USA women's wheelchair basketball Paralympic team, five-time Paralympic gold medalist in track Marla Runyan — the only US athlete to have competed in both the Paralympic and Olympic Games — and multi-sport specialist Susan Hagel.

Hagel competed in six Paralympic Games across three different sports — archery, track and field, and wheelchair basketball — picking up four gold and two bronze medals along the way.

Barrier-breakers honored as Class of 2025 Legends

Also earning Hall of Fame honors are two trailblazing Black women, named as the Legends of the Class of 2025.

Renowned volleyball player and 1984 silver medalist Flo Hyman — whose work to bolster Title IX as well as her role helping Team USA to their first-ever Olympic medal in women's volleyball were crucial to growing the sport in the US — will be posthumously celebrated.

Honored alongside Hyman will be 1976 Olympic bronze medalist Anita DeFrantz, the first and only Black woman to medal in rowing.

DeFrantz, the International Olympic Committee's (IOC) first-ever woman member, is still helping to make Olympic history, casting the deciding vote to elect the IOC's first woman president this past March.

The Class of 2025 is the 18th overall group and first since 2022 to enter the Hall of Fame.

Following their July 12th induction, the US Olympic and Paralympic Hall of Fame will bloom to 210 individual and team members.
 
 

The WNBA starts a new chapter on Tuesday, as the Golden State Valkyries — the league's first expansion team since 2008 — take the court in a preseason showdown against fellow California side Los Angeles.

"It'll be our franchise's first game," Valkyries forward Kayla Thornton told the media from training camp. "I'm just excited to get to the court."

Drawing from both April's college draft and an earlier expansion draft within the league, the Valkyries' roster is still a work in progress as they attempt to form a distinct playing style under first-year head coach Natalie Nakase.

Backed by an inaugural training camp lineup that appears to prioritize international talent, the team already waived Maryland standout Shyanne Sellers after drafting the guard 17th overall last month.

Cinderella selection Kaitlyn Chen — taken No. 30 overall from 2025 national champion UConn's roster — is now Golden State's only NCAA draftee.

"It's just that I have to choose the best 12 that are going to fit. Doesn't mean it's the most talented, it means it's the best 12," Nakase said of the Saturday decision to waive Sellers.

Along with the pains of refining a 2025 roster and building team culture, the WNBA's 13th team — the league's first new addition since the Atlanta Dream joined — is also experiencing the natural growing pains of expansion.

Golden State Warriors Sports — the ownership group behind both the Valkyries and the NBA's Golden State Warriors — recently rebranded to simply "Golden State" to indicate equity among its properties.

The Valkyries will make their WNBA debut in a preseason exhibition game against the LA Sparks at 10 PM ET on Tuesday.
