The world's top tennis stars are rolling in Melbourne, as the first round of the 2026 Australian Open wrapped early Tuesday morning with only a few ranked seeds suffering early defeats.

World No. 15 Emma Navarro was the highest-ranked US player to fall in the first round, with the 24-year-old exiting the season's first Grand Slam in a 6-3, 3-6, 3-6 loss to Poland's No. 50 Magda Linette on Sunday.

No. 11 Ekaterina Alexandrova also stumbled in the first round, with her Melbourne run ending in a three-set loss to Turkey's No. 112 Zeynep Sönmez on Saturday before No. 68 Peyton Stearns ousted fellow US star and 2020 Australian Open champion No. 30 Sofia Kenin in straight sets on Sunday.

Many contenders still remain in the hunt, however, as the entire WTA Top 10 cruised through their opening matchups to advance to the Slam's second round.

That said, fans will miss out on one highly anticipated showdown, as wild card entry Venus Williams's first-round loss ended the 45-year-old tennis icon's path to a second-round clash with US favorite No. 3 Coco Gauff.

The 2026 Australian Open continues when the Slam's second round kicks off with a Tuesday night slate that features stars like No. 1 Aryna Sabalenka, No. 3 Coco Gauff, and No. 7 Jasmine Paolini.

Tuesday's action begins at 7 PM ET, with all Melbourne matches airing live across ESPN platforms.

World No. 75 Alexandra Eala opened her 2025 US Open campaign with a bang on Sunday, upsetting Denmark's No. 14 Clara Tauson 6-3, 2-6, 7-6 (13-11) to become the first-ever Filipina player to win a Grand Slam match in the Open Era.

"I'm so blessed to be the first to do this, I take so much pride in representing my country," Eala said following the victory. "It makes what I do bigger than myself."

The 2025 tennis season has been a banner year for the rising star, as a 2025 Miami Open run saw Eala defeat both 2025 Australian Open champ No. 6 Madison Keys and six-time Grand Slam winner No. 2 Iga Świątek en route to becoming the first-ever Filipina to advance to a WTA semifinal.

The 20-year-old has played professionally since graduating from Spain's Rafael Nadal Academy in 2023, with Sunday's win coming just three years after Eala claimed the 2022 US Open girls' championship.

The crowd in Queens was overwhelmingly behind their former junior champ on Sunday — a boost that Eala was quick to acknowledge in her post-match interview.

"To be Filipino is something I take so much pride in," Eala told reporters. “I don't have a home tournament, so to be able to have this community here at the US Open, I'm so grateful they made me feel like I'm home."

"This match is one for the books for me," she summed up.

Eala now moves on to the US Open's second round, hitting the court again on Wednesday against an as-yet-undetermined opponent.

The first round of the 2025 US Open continues on Monday and Tuesday, with live coverage of the New York Grand Slam airing across ESPN platforms.

The grass court chaos of Wimbledon didn't disappoint this week, as the unpredictable surface claimed more than one surprise victim in the 2025 Grand Slam's first round.

A full 10 of the London tournament's 32 seeded players fell in the competition's first round, including four of the WTA's Top 10: World No. 2 Coco Gauff, No. 3 Jessica Pegula, No. 6 Qinwen Zheng, and No. 9 Paula Badosa.

"I should just play no tournaments, get no wins, then roll into Wimbledon, and maybe I'll have better results," US star Pegula joked after her two-set Tuesday loss to Italy's No. 116 Elisabetta Cocciaretto, referencing her recent wins.

Gauff's short Wimbledon outing also represented a new challenge for the 21-year-old standout, as the top-ranked US tennis player struggled to bounce back after winning the 2025 French Open last month.

"I feel like mentally I was a little bit overwhelmed with everything that came afterwards," Gauff told ESPN. "So I didn’t feel like I had enough time to celebrate and also get back into it."

The upsets continued as Wimbledon entered its second round on Wednesday morning, claiming several more seeded players like world No. 5 Jasmine Paolini and No. 15 Diana Shnaider, though both No. 1 Aryna Sabalenka and unseeded fan favorite Naomi Osaka cruised into the Slam's third round on two-set wins.

No. 8 Madison Keys now leads the US contingent, with fellow US contender No. 12 Amanda Anisimova joining the 2025 Australian Open champion in snagging their own two-set, second-round victories on Wednesday.
