Wimbledon 2023: Carlos Alcaraz, Novak Djokovic, Daniil Medvedev, Aryna Sabalenka Enter Round Of 16

Carlos Alcaraz reached the last 16 at Wimbledon on Saturday after a tough battle against Nicolas Jarry as defending women's champion Elena Rybakina prepared to face Britain's last hope Katie Boulter. Rain returned to the All England Club, meaning play on Centre Court started under the roof. Top seed Alcaraz is seen as the biggest threat to Novak Djokovic, who is gunning for a record-equalling eighth men's title and 24th Grand Slam crown overall. But the Spaniard, who won the grass-court Queen's tournament last month, was made to work hard for the win by his Chilean opponent, seeded 25th, before prevailing 6-3, 6-7 (6/8), 6-3, 7-5. Alcaraz bounced back from losing his first set of the tournament to lead 2-1 but narrowly avoided going a double break down in the fourth set before rediscovering his mojo.

"I'm really happy with the level that I played to get through this really tough match," said a relieved Alcaraz.

He added: "It was really, really close. He has great shots... I would say the key is to believe all the time and stay focused."

Alcaraz, attempting to become the third-youngest player in the Open Era to win the title after Boris Becker and Bjorn Borg, was playing his second match in two days after rain delays earlier in the week.

Djokovic, by contrast, moved serenely into the last 16 late on Friday, beating Stan Wawrinka in straight sets.

Men's third seed Daniil Medvedev lost the first set against close friend Marton Fucsovics but recovered to win 4-6, 6-3, 6-4, 6-4.

Greek fifth seed Stefanos Tsitsipas, who beat Andy Murray in a five-set thriller over two days in the second round, eased past Serbia's Laslo Djere in straight sets.

Last year's surprise women's champion, Rybakina, who has not hit top form so far,
