Il Nuovo Postiglione - Alcaraz in Wimbledon last 16 as seeds tumble again

The Spanish second seed eventually overcame German world number 125 Struff 6-1, 3-6, 6-3, 6-4 to stay on track for a third straight Wimbledon crown.

But Alcaraz will have to cut out his errors if he is to become just the fifth man in the Open era perform that feat.

"I knew it was going to be really difficult. I had to be really focused. His game suits the grass with the big serves," said the 22-year-old.

"It's stressful. To be honest, I was suffering in every service game today, 0-30, break points down.

"I'm really pleased that I was fighting, running for every ball and making great shots."

Alcaraz, watched by former England captain Gary Lineker and former world heavyweight champion Anthony Joshua, made 28 unforced errors in an inconsistent display on Centre Court.

But he conjured enough moments of magic to eventually subdue the world number 125 and book his place in the fourth round, where he will meet Russia's Andrey Rublev.

Alcaraz had been pushed to the brink in a five-set win over 38-year-old Italian Fabio Fognini in the first round and looked below his best again in a second-round victory over British amateur Oliver Tarvet.

- Women seeds crash -

The women's draw is bereft of star names after the departure of a succession of top players.

Keys' 6-3, 6-3 defeat by Germany's Laura Siegemund means only world number one Aryna Sabalenka is still alive at the All England Club out of the top six women's seeds.

Coco Gauff, Jessica Pegula, Jasmine Paolini and Zheng Qinwen have already fallen by the wayside.

On the men's side, half of the top-10 seeds have gone, though Alcaraz and world number one Jannik Sinner are still standing.

US sixth seed Keys had won 13 of her 14 Grand Slam matches this year, but made 31 unforced errors in a lacklustre display against 37-year-old Siegemund, ranked 104 in the world.

Sabalenka will be desperate to buck the trend when she faces a potentially tricky encounter against former US Open champion Emma Raducanu in the third round.

Raducanu ousted 2023 Wimbledon winner Marketa Vondrousova in the second round and is in the mood to cause an upset.

"I think having won against Marketa, she's also a really top opponent, so that gives me confidence. I feel amazing," said the 22-year-old.

"Of course, Aryna is number one in the world, she's been so dominant in the women's game," she said. "I know it's going to be a massive challenge."

Earlier at the All England Club, Japan's four-time Grand Slam champion Naomi Osaka lost in three sets to Russia's Anastasia Pavlyuchenkova, ranked 50th in the world.

Osaka has not reached the fourth round of a Grand Slam since she won the Australian Open in 2021 but is still hungry for success.

"I feel like while I still have the opportunity to try to do it, I want to, even though I get very upset when I lose, but I think that's my competitive nature. That's also the younger sister syndrome," she said.

There were also wins for Britain's Sonay Kartal, 13th seed Amanda Anisimova and Elise Mertens.

US men's fifth seed Taylor Fritz avoided a third straight five-setter, beating Spains' Alejandro Davidovich Fokina 6-4, 6-3, 6-7 (5/7), 6-1.

Britain's Cameron Norrie saw off Italian Mattia Bellucci in straight sets to qualify the quarter-finals for the first time since 2022, when he reached the last four.

Highly promising Brazilian teenager Joao Fonseca was ousted by Chilean qualifier Nicolas Jarry.

It took US men's 10th seed Ben Shelton just 71 seconds to complete his second-round match, sealing a 6-2, 7-5, 6-4 win against Australia's Rinky Hijikata after the match was halted on Thursday due to failing light.
