Madrid Open: Aryna Sabalenka comes from a set down to beat Naomi Osaka

World number one Aryna Sabalenka came from a set and a break down to beat Japan's Naomi Osaka in the fourth round of the Miami Open and progress to the quarter-finals.

Four-time Grand Slam champion Sabalenka secured her 15th consecutive victory of the year - and ninth in a row in Madrid - by winning 6-7 (1-7) 6-3 6-2 in two hours and 20 minutes.

The 27-year-old had not lost a match in the Spanish capital since 2023 but she was tested early on by fellow four-time major winner Osaka, who was playing some of her strongest tennis of the season.

Also in the last 16 on Monday, American third seed Coco Gauff suffered a 4-6 6-1 6-7 (5-6) defeat by Czech Linda Noskova.

Gauff, who was lost to Sabalenka in the Madrid final last year, was 4-1 up in the final set and 4-2 ahead in the deciding tie-break before Noskova, seeded 13th, battled back twice to claim her spot in the last eight.

American Gauff, who has been unwell with a stomach virus, will drop from third to fourth when the updated world rankings are released, with Poland's Iga Swiatek replacing her.

The reigning French Open champion was ruthless in the second set after losing the first and looked a safe bet to advance to the next round at the expense of Noskova, after breaking the 21-year-old for a second time in the third set.

But world number 13 Noskova produced an impressive comeback in front of the Spanish crowd as Gauff faltered and will face Ukrainian Marta Kostyuk in the quarter-finals on Wednesday.

Kostyuk, 23, won 6-2 6-3 against American Caty McNally to celebrate her ninth victory in a row and back-to-back Madrid quarter-finals.

"Sometimes I get lost on court, especially in the second [set], as it happened today," said Noskova. "I had to find my rhythm all over again in the third [set]."

Meanwhile, Sabalenka will take on American Hailey Baptiste, who defeated Belinda Bencic 6-1 6-7 (14-16) 6-3 in her fourth-round match, on Tuesday.

She defeated Baptiste, 24, in the quarter-finals of the Miami Open on her way to winning the title last month.
