After early exits from the 2025 BNP Paribas Open at Indian Wells, US standouts continued to struggle this week, failing to advance past the Round of 16 at the Miami Open.

After ending the dream of a single Sunshine Double winner by outlasting Indian Wells champion No. 6 Mirra Andreeva in Sunday's three-set Round of 32 battle, US contender No. 17 Amanda Anisimova fell to the UK's unseeded Emma Raducanu in straight sets on Monday.

The Round of 16 action also saw world No. 1-ranked Aryna Sabalenka knock out US stalwart No. 14-seed Danielle Collins in two sets — a fate similarly suffered by No. 3-ranked Coco Gauff, who fell to Poland's unseeded Magda Linette by the exact same 6-4, 6-4 scoreline.

"It wasn’t great today," Gauff told reporters after the match. "It hasn’t been the last few weeks — I’m trying to figure that out. Definitely not happy about it."

The 21-year-old star 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.

"It's just a series of not having great results and feeling confident on the court," she said of her current struggles.

The lone US player still on Miami's court is world No. 4 Jessica Pegula, who easily ousted Ukraine's No. 23-seed Marta Kostyuk 6-2, 6-3 on Monday.

Unseeded players shine at 2025 Miami Open

Though five of the WTA's Top 9 players — from Sabalenka to her next opponent, China's No. 9 Qinwen Zheng — advanced to this week's Miami Open quarterfinals, a trio of unseeded athletes are also making deep runs in Florida.

The aforementioned Raducanu is displaying the same tenacity that helped her win the 2021 US Open at just 18 years old, dispatching a trio of US players in No. 8-seed Emma Navarro, unseeded McCartney Kessler, and Anisimova to claim a Wednesday quarterfinal date with US star Pegula.

Also causing chaos in Miami is unseeded 19-year-old Filipino pro Alexandra Eala, who rolled over 2025 Australian Open champion and world No. 5 Madison Keys on Sunday, ultimately earning a shot at No. 2 Iga Świątek on Wednesday.

But first, Gauff's unseeded conquerer Linette will kick off the tournament's quarterfinals by facing No. 6-seed Jasmine Paolini.

The Italian star already ushered Japan icon Naomi Osaka out of the competition in Monday's three-set Round of 16 battle, and will take aim at Linette's similarly impressive unseeded run on Tuesday.

How to watch the 2025 Miami Open quarterfinals

The 2025 Miami Open quarterfinals will kick off on Tuesday, when Magda Linette will face No. 6 Jasmine Paolini at 3:20 PM ET, before No. 1 Aryna Sabalenka takes on No. 9 Qinwen Zheng at 7 PM ET.

The remaining two quarterfinals will take Wednesday's court, with the timing for Emma Raducanu vs. No. 4 Jessica Pegula and Alexandra Eala vs. No. 2 Iga Świątek yet to be determined.

All 2025 Miami Open matches will be covered live on the Tennis Channel.

Top-ranked players cruised through the competition at the 2025 BNP Paribas Open at Indian Wells over the weekend, with few early-round upsets leaving the sport’s best firmly intact as the Round of 32 enters its second day.

Defending champion and world No. 2 Iga Świątek has put together the tournament's most dominant performance so far, with the Polish phenom dropping just four total games in her first two victories over France's Caroline Garcia and Ukraine's Dayana Yastremska.

On the other hand, several lower seeded players suffered early round losses.

Yastremska opened her Indian Wells account by ousting Tunisian star and world No. 32 Ons Jabeur 6-3, 6-1 in Friday's first round.

Meanwhile, Saturday saw Canada's No. 27 Leylah Annie Fernandez and the US's No. 18 Amanda Anisimova fall in three-set first-round battles with Romania's Jaqueline Cristian and Switzerland's Belinda Bencic, respectively.

Sunday's play went mostly according to seeding, with the lone second-round upset win going to Ukrainian Elina Svitolina. The world No. 23 player sent the US's No. 14 Danielle Collins packing with a 6-2, 6-4 defeat.

Top 5 players look to roll to the Round of 16

While Świątek and US standout No. 4 Jessica Pegula booked their Round of 16 spots on Sunday, world No. 1 Aryna Sabalenka as well as US stars No. 3 Coco Gauff and No. 5 Madison Keys will take the court for their second-round matchups on Monday afternoon.

Keys faces perhaps the toughest path to the trophy.

If the 2025 Australian Open champion clears Belgium's No. 28 Elise Mertens on Monday, she could face Gauff in an all-US quarterfinal on Wednesday.

Then, a potential date with 2024 US Open winner Sabalenka — who Keys defeated to secure her first-ever Grand Slam win — awaits in the tournament's penultimate round.

The conclusion of the tournament's second round is currently underway, with live coverage airing on the Tennis Channel.

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.

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.

With the US Open's first round coming to a close, both surprise performances and expected wins headlined the season's final Grand Slam heading into today's second round.

Naomi Osaka pulls off stunning upset with US Open win

Looking decidedly dangerous, 2020 US Open champ Naomi Osaka — a wild card entry at 88th in the world — beat No. 10 Jeļena Ostapenko in straight sets on Tuesday.

After stepping away for mental health reasons and the birth of her daughter, yesterday marked Osaka’s first top-10 win in over four years.

"Last year, I was watching Coco play, and I so badly wanted to step on these courts again and I didn’t know if I could," an emotional Osaka told reporters after the victory. "Just to win this match and to be in this atmosphere means so much to me."

Other past US Open champions see mixed results

Joining Osaka in the second round are fellow US Open winners Iga Świątek (2022) and Coco Gauff (2023). No. 3 Gauff aced her first match 6-2, 6-0 on Monday, but No. 1 Świątek faced a tougher challenge from Russian Kamilla Rakhimova on Tuesday.

The Polish phenom made 41 unforced errors, coming dangerously close to a forced third set before a tiebreaker allowed Świątek to continue her hunt for a sixth Grand Slam title.

Other past US Open champs weren’t so lucky, with 2019's Bianca Andreescu and 2021's Emma Raducanu joining 2017's Sloane Stephens on the ousted list.

Retiring Danielle Collins exits final Grand Slam singles tournament

While most of the 32 seeded singles players survived round one, US star Danielle Collins's run ended on Tuesday. Coming off a solid fourth-round Wimbledon exit, the world No. 11 fell to No. 49 Caroline Dolehide 1-6, 7-5, 6-4, despite defeating the fellow US pro in five of their six previous meetings. 

Collins, who announced her plan to retire after this season in January, suffered an abdominal injury at the Olympics that saw her miss the Toronto and Cincinnati US Open tune-ups.

Ash Barty continued to roll on Thursday, breezing past Madison Keys 6-1, 6-3 to reach the final of the Australian Open. She’s the first home player to reach the women’s final since Wendy Turnbull in 1980.

With the win, Barty’s hopes of becoming the first women’s home champion since Chris O’Neil in 1978 are still alive.

Having dropped just 21 games in six matches, Barty recorded the fewest games lost en route to a Grand Slam title match since Serena Williams dropped 16 en route to the 2013 US Open final. It’s also tied for fourth-lowest this century: Williams dropped 19 at the 2012 US Open, sister Venus dropped 20 at Wimbledon in 2009 and Serena also dropped 21 at the 2013 French Open.

Throughout the 62 minute match, Barty racked up 20 winners to 13 unforced errors. Keys, meanwhile, had only eight winners to 24 unforced errors.

“It’s tough,” Keys said of Barty’s play after the match. “It sucks. She’s just playing incredibly well. I mean, you have a game plan in your head, but she’s just executing everything so well.”

The Australian will next take on No. 27 American Danielle Collins, who upset No. 7 Iga Swiatek 6-4, 6-1 to reach her first Grand Slam final. It was Collins’ seventh career top 10 win.

When asked about Collins, Barty called her “one of the most fierce competitors out here.”

“She loves to get in your face and loves to really take it on,” Barty said. “It’s going to be a challenge for me to try and neutralize as best that I can, but it is certainly nice to see her back out here playing her best stuff.”

While Barty leads the head-to-head against Collins 3-1, the American hasn’t lost a complete match since Indian Wells last October, marking a streak of 11-straight wins. She had to retire to Alison Riske in the Linz Open semifinals in November.

The 28-year-old slammed home 27 winners and only 13 unforced errors on Thursday. Her aggressive approach to the game was no match for Swiatek, who said as much after the match.

“I was prepared for her playing aggressive game, but I think that was the fastest ball I have ever played against on a match,” Swiatek said. “For sure in practices I have hit maybe the same speed, but on matches it’s different because players don’t want to take that much risk. But it seemed for her that it wasn’t even risky because she was playing it with control.

“So I am impressed, and huge respect to her because she’s playing a great game. I’m just curious how it’s gonna look like on the final, and I’m gonna for sure be watching and learning.”
