'Brave' Magda Linette ousts Coco Gauff, Fils tops Tiafoe on tough Monday in Miami for U.S.

Home favorites hit a wall on a trying Monday at the Miami Open, with Coco Gauff and Frances Tiafoe among the U.S. stars sent packing.

Gauff, a resident of nearby Delray Beach, was ousted by Magda Linette. The unseeded Pole capitalized on four of her six break points for a 6-4, 6-4 victory that marked the fifth Top 5 win of her career.

“I think it was really important for me to keep pressing Coco's serve to make sure she feels the pressure. I'm glad that I was returning well,” Linette told press.

“I was really brave. Then I was able to back it up with pretty solid service games because she's really tough.”

Jasmine Paolini stands between Linette and the semifinals, following her 3-6, 6-4, 6-4 comeback against Naomi Osaka. The third-ranked Gauff hit 12 double faults and dropped to 0-3 in the round of 16 at Hard Rock Stadium.

Her countrywoman Amanda Anisimova, who ended Mirra Andreeva’s 13-match win streak Sunday evening and won the season’s opening WTA 1000 event in Doha, was overmatched by Emma Raducanu. The 2021 US Open title holder cruised, 6-1, 6-3, to achieve her best result on the 1000 stage.

“I feel comfortable. I feel like in my environment, in my surroundings with the people I'm with, I feel pretty relaxed, and I can be myself and expressive and true to myself. That's important for me,” shared the Brit.

Ninth seed Zheng Qinwen finished off Ashlyn Krueger, 6-2, 7-6 (3), to book a last-eight clash with Aryna Sabalenka. The world No. 1 improved to 7-0 against Danielle Collins, advancing past the reigning champion, 6-4, 6-4. Collins will depart the Top 20 next Monday as a result.

Meanwhile, Tiafoe went down in a spirited first-time meeting between competitors separated by one ranking place. World No. 18 Arthur Fils battled to a 7-6 (11), 5-7, 6-2 victory on Grandstand, having saved six set points in the opener and later seeing the 17th-ranked Tiafoe save two match points on his serve at 4-5 in the second set.

The 20-year-old is bidding to reach the quarterfinals at both Sunshine Double stops and next gets top seed Alexander Zverev, a 6-4, 7-5 winner over Jordan Thompson. Tiafoe fell to 9-6 on the year.

Tomas Machac continued his strong 2025 start by easing past Reilly Opelka, 7-6 (1), 6-3. The No. 20 seed did not face a break point in out-serving his 6-foot-11 opponent by taking 48 of 58 points overall at the line.

Compatriot Jakub Mensik awaits this month’s Acapulco champion in the round of 16. The 19-year-old earlier took out Indian Wells champion Jack Draper before backing it up by defeating Roman Safiullin, 6-4, 6-4.

Taylor Fritz and Jessica Pegula ensured their nation got into the win column, respectively. Fritz avenged his Dallas defeat to Denis Shapovalov, 7-5, 6-3, while Pegula dismissed Marta Kostyuk, 6-2, 6-3.
