Clay season is in full swing, as the world's top tennis talents hit the court at the 2025 Madrid Open this week, seeking strong performances on the tricky surface before contending in the French Open next month — the clay court's Grand Slam.

The second round of the 2025 Madrid Open kicked off early Thursday morning, with much of the sport's Top 25 hunting the WTA 1000 event's title.

Leading the field is clay specialist Iga Świątek, as the world No. 2 player will look to defend her 2024 Madrid trophy and stir up momentum for the month ahead.

Despite ceding her No. 1 ranking to Aryna Sabalenka late last year, Świątek is nearly impossible to beat on clay, with four French Open championships already under her belt.

The 23-year-old, however, is coming off a quarterfinal upset loss to eventual champion No. 18 Jeļena Ostapenko at last week's 2025 Stuttgart Open — a clay-court tournament Świątek's won twice.

That said, Świątek is off to strong start in Madrid, where she defeated No. 72 Alexandra Eala 4-6, 6-4, 6-2 on Thursday — enacting revenge on the teen Philippines phenom after Eala defeated her in the 2025 Miami Open final last month.

Gauff seeks 2025 season turnaround on clay

Along with Świątek, other players to watch this week include US favorites No. 3 Jessica Pegula, No. 4 Coco Gauff, and No. 5 Madison Keys.

Keys and Gauff will begin their 2025 Madrid Open runs on Thursday, while Pegula will start serving in the second wave of the tournament's round of 64 on Friday.

Gauff has seen past success on clay, reaching the French Open final back in 2022 — to face eventual champion Świątek.

The 21-year-old star, however, is in the midst of a particularly frustrating 2025 run, having yet to advance past the quarterfinals of any competition since winning the 2024 WTA Finals.

"I've started to believe that you can just turn it around any week. And just as quickly as you can go on a tear, you can also lose," Gauff said this week.

The 2025 Madrid Open runs through Saturday, May 3rd. Continuing live coverage will air on the Tennis Channel.

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.

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."
