Italian Matteo Berrettini cruised into the quarter-finals of the men's singles at Wimbledon with a confident straight-set victory over Ilya Ivashka.

Berrettini lost just one service game to the Belarusian as he sealed victory with a stylish forehand winner.

He will next face Felix Auger-Aliassime or fourth seed Alexander Zverev.

Russian Karen Khachanov booked his place in the last eight by winning a five-set thriller against American Sebastian Korda 3-6 6-4 6-3 5-7 10-8.

An enthralling final set on court 18 featured a remarkable 13 breaks of serve, as Khachanov squandered three opportunities to serve out for the match at 5-4, 6-5 and 7-6.

At 9-8 Khachanov, seeded 25th, eventually managed to hold his serve to win a gruelling match in three hours and 49 minutes.

"I would say it's not common, but it is what it is with the nerves," Khachanov said of the 13 breaks.

"When you are returning better, you start to read the serves better, and then in play, in the rallies, both of us were more stressed, more tight.

"At the end, the one who deal betters with this wins the match. It was more about this rather than who plays better."

Khachanov will face Canada's Denis Shapovalov, after Andy Murray's conqueror breezed through with a 6-1 6-3 7-5 win over Roberto Bautista Agut of Spain.

Fifth seed Andrey Rublev of Russia has been knocked out as Hungarian Marton Fucsovics produced a brilliant comeback to triumph 6-3 4-6 4-6 6-0 6-3.

World number 48 Fucsovics will face top seed Novak Djokovic in the next round after the Serb's routine 6-2 6-4 6-2 win over Chile's Cristian Garin.
