Wild card entrant Alexandra Eala of the Philippines continued her epic 2025 Miami Open run on Wednesday, as the world No. 140 took down No. 2 Iga Świątek in a 6-2, 7-5 straight-set stunner.

Without massive power as part of her game, the 19-year-old leaned hard on her fast feet and intelligent shot-making, earning 43 of her 77 points from serve returns.

"My coach told me to run, to go for every ball, to take all the opportunities I can because a five-time [Grand] Slam champion is not going to give you the win," said Eala.

At the same time that Eala was disrupting Świątek's rhythm, the tournament's defending champion struggled with her serve and ultimately committed 32 unforced errors in the loss.

"She was really aggressive and she kept her focus, and some of these shots were pretty out of nowhere," commented Świątek after the match, as she joined a growing list of big-name departures from the Florida competition.

Eala emblazons her name into Filipina sports history

As one of the sport's top junior prospects, Eala won the girls' doubles title at both the 2020 Australian Open and 2021 French Open, before taking the girls' singles championship at the 2022 US Open.

Even so, "being a successful junior doesn’t mean you are going to be a successful professional," Eala acknowledged.

Her dramatic Miami Open run begs to differ, as Eala dismissed two other Grand Slam winners from the tournament en route to her Wednesday’s quarterfinal date with Świątek.

First, she sent Latvia's No. 25 Jeļena Ostapenko — the 2017 French Open winner packing in Friday's Round of 64, then dispatched 2025 Australian Open champ No. 5 Madison Keys in Sunday's Round of 32 — both in just two sets.

Her trio of Miami Open wins over Top 30 players now counts as the total tally for her entire country, with Eala also becoming the first-ever Filipina to advance to a WTA semifinal.

With the WTA's next rankings updates, she will also become the first player from the Philippines to crack into the Top 100 — a mark Eala will launch past as her victory over Świątek already guarantees her at least a No. 75 ranking.

"I'm just in disbelief right now," Eala said in her on-court interview. "I'm so happy, and so blessed to be able to compete with such a player on this stage."

The Filipina teen's next hurdle in her historic run is US star No. 4 Jessica Pegula, who she'll face at 8:30 PM ET on Thursday, with a Saturday championship date against world No. 1 Aryna Sabalenka guaranteed for the victor.

Thursday's semifinal between Eala and Pegula will air live on The Tennis Channel.

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.

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.
