Former world No. 1 tennis star Naomi Osaka hit another setback on Wednesday, falling in straight sets in the first round of the 2025 BNP Paribas Open at Indian Wells to Colombia’s unseeded Camila Osorio.
Osaka earned her first-ever WTA title at Indian Wells, defeating Daria Kasatkina to become the event's 2018 champion.
Wednesday's 6-4, 6-4 loss marked the now-No. 56 Osaka's first return to the court since an abdominal injury forced an early end to her impressive 2025 Australian Open run.
"It feels like a bump in the road," said the four-time Grand Slam champion after the match. "I don’t feel like I played well at all, but I still feel like I had so many chances to be in the match."
The match was Osorio's Indian Wells debut, with the No. 53 player now standing as the only Colombian woman to ever defeat a former world No. 1 player.
"It's a dream come true," said Osorio. "I really wanted to play on this court and was really excited and looking forward to playing a champion like Naomi, so I can't believe it."
WTA stars aim for title, rankings boosts at Indian Wells
Indian Wells serves as the opener for the Sunshine Double, a pair of early-season high-profile WTA 1000 events that sees the world’s top players hitting the US hardcourt. The annual tournament duo includes this week's event in California and, later this month, Florida's Miami Open.
Positioned in the tennis calendar's longest break between Grand Slams, the Sunshine Double often gives players a competitive opportunity to build up their rankings by accruing points in the lead-up to May's French Open.
To that end, the world's top contenders will all enter the Indian Wells fray on Friday, including No. 1 Aryna Sabalenka and the tournament's defending champion, No. 2 Iga Świątek.
The event's convenient West Coast locale also attracts a wealth of US entrants, with No. 3 Coco Gauff, No. 4 Jessica Pegula, and 2025 Australian Open champion No. 5 Madison Keys joining fellow Stateside competitors No. 8 Emma Navarro, No. 14 Danielle Collins, and No. 18 Amanda Anisimova on this week's Indian Wells court.

US tennis player Madison Keys earned her first-ever Grand Slam title on Saturday, taking down back-to-back defending champ and world No. 1 Aryna Sabalenka in the 2025 Australian Open final.
On the heels of a three-set semifinal ousting of No. 2 Iga Świątek last Thursday, Keys' 6-3, 2-6, 7-5 Saturday victory made her the first player to upset both the world No. 1 and No. 2 in the same Grand Slam since Svetlana Kuznetsova did so at the 2009 French Open. The 29-year-old is also the first to do it in Melbourne since Serena Williams in 2005.
Only three other WTA players have racked up more Grand Slam main draws before winning their first title. On Saturday, Keys tied Caroline Wozniacki for making the most Australian Open main-draw singles appearances before lifting the trophy.
Keys's Australian Open run included five wins over seeded opponents, four of them in the WTA's Top 10 entering the tournament. Plus, with five three-set victories, Keys tied the record for the most three-set wins at any of the four Grand Slams.
However, none of those records compare with winning her first major.
"I’ve wanted this for so long," Keys said holding her trophy during the post-match ceremony.
Keys' championship was years in the making
Keys burst onto the pro scene on her 14th birthday back in 2009, and has been a Top 20 mainstay for most of the last decade.
The US star has appeared in at least the quarterfinal round of all four majors multiple times. However, she had only one Grand Slam final under her belt prior to this weekend's championship match — a 2017 US Open loss to Sloane Stephens.
Ultimately, it took relinquishing her desperation to win a Slam to actually snag that elusive trophy.
"I've done a lot of work to no longer need [winning a Grand Slam]," Keys explained after her win. "I really wanted it, but it's no longer the thing that was going to define me, and kind of letting go of that burden, I finally gave myself the ability to play for it."
Slam win returns Keys to the WTA's Top 10
The WTA updated their rankings early Monday, with Keys's breakthrough performance boosting her to No. 7 — her first Top 10 slot since January 2023. The new rank also ties her career-high, with Keys first peaking at No. 7 in October 2016.
Keys's rise also solidifies the US as arguably the nation most flush with the sport's top talent. The US now boasts four players in the Top 10, with Keys joining No. 3 Coco Gauff, No. 6 Jessica Pegula, and No. 9 Emma Navarro. No other nation has more than one athlete in that elite tier.
That said, the WTA's best stayed put in Monday's rankings. Despite their Australian Open losses, all four top seeds — Sabalenka, Świątek, Gauff, and No. 4 Jasmine Paolini — retained their top spots.
In the biggest upset of the 2025 Australian Open so far, 19-seed Madison Keys defeated world No. 2 Iga Świątek in a back-and-forth three-set semifinal early Thursday morning.
Entering as the tournament's only athlete to win every set, five-time Grand Slam champion Świątek conceded more games to Keys than in her previous five Australian Open matches combined.
Keys's speedy serve and heavy forehand paired with a Świątek double-fault pushed the match to a tie-break decider, with the US star ultimately winning 5-7, 6-1, 7-6 (10-8).
"It just became who can get that final point and who can be a little bit better than the other one," Keys said post-match. "I'm happy it was me."
Keys's victory is just the latest chapter in a 2025 Australian Open run that's seen her beat three Top 10 contenders in Świątek, No. 6 Elena Rybakina, and No. 10 Danielle Collins. Those victories earned the 29-year-old her own Top 10 spot in next Monday’s WTA rankings.
With Thursday's win, Keys booked her second-ever Grand Slam championship match, returning to the sport's top stage for the first time since the 2017 US Open.
One last challenge awaits Keys
To claim her career's first Grand Slam trophy, however, Keys will have to defeat reigning champion and world No. 1 Aryna Sabalenka, who comfortably downed Spain's No. 11 Paula Badosa 6-4, 6-2 on Thursday in pursuit of a third-straight Australian Open title.
In their five previous meetings, Keys has only beaten Sabalenka once, topping her in Berlin in 2021.
Sabalenka won their most recent bout in the 2023 US Open semifinals. However, that three-set slog was similar to Keys's gritty victory over Świątek and, if she can maintain the composure and energy she displayed on Thursday, the US star's momentum could fuel her to similarly stun Sabalenka.

Saturday's Australian Open final between Keys and Sabalenka will take the court at 3:30 AM ET, with live coverage on ESPN.
World No. 3 Coco Gauff exited the 2025 Australian Open on Monday night, falling 7-5, 6-4 to Spain's No. 11 Paula Badosa in the Grand Slam's quarterfinal round.
Gauff's recent improvements seemed to fade in her first loss of the year, which saw the 2025 United Cup champ record 41 unforced errors, including 28 missed forehands and six double-faults.
As a result, Badosa advances to her first-ever Grand Slam semifinal, a marked comeback after a 2023 injury nearly ended her career.
"I would never think that, a year after, I would be here," Badosa said post-match. "I've been through a lot."
Sabalenka looms after quarterfinal victory
Badosa moves on to face back-to-back defending champion Aryna Sabalenka on Thursday, as the world No. 1 sets her sights on becoming the first three-peat Australian Open women's champ this century.
Sabalenka advanced past No. 27 Anastasia Pavlyuchenkova in an early Tuesday morning quarterfinal to reach her 10th major semifinal in her last 11 Grand Slams.
The 6-2, 2-6, 6-3 victory didn't come easily, though, as Pavlyuchenkova managed to snap the 26-year-old's 25-set Australian Open winning streak which dates back to her 2023 final win.
"I’m really glad that at some point I was able to put myself back together," said Sabalenka about the tough match. "I was able to keep fighting, keep trying, and I was able to turn around this match. It was a really difficult one."
US players to close out Australian Open quarterfinals
The Melbourne Slam's remaining two quarterfinals each place a US tennis star in the spotlight on Tuesday.
Fresh off ousting No. 10 Danielle Collins and No. 6 Elena Rybakina in the third and fourth rounds, No. 19 Madison Keys will square off against No. 28 Elina Svitolina for a shot at the semis. This will be Keys's first match against the Ukrainian since taking a two-set victory over Svitolina in Adelaide in January 2022.
The nightcap pits three-set specialist No. 8 Emma Navarro against perennial contender No. 2 Iga Świątek, marking the second-ever meeting — and first since 2018 — between the 23-year-olds.
The Polish phenom has yet to drop a set all tournament, and has seemed near-unbeatable after losing just four games across her last three matches. That said, Navarro has proved she just won't quit, leading the WTA in three-set contests over the last year — and gritting out a 24-9 record in the same span. Consequently, the longer Tuesday's match runs, the more it will likely favor the US star.

No. 19 Madison Keys will clash with No. 28 Elina Svitolina starting at 7:30 PM ET on Tuesday, with No. 8 Emma Navarro's bout against No. 2 Iga Świątek beginning at 9 PM ET.
Both Tuesday quarterfinals will be broadcast live across ESPN’s platforms.
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.
