Roger Federer's cheeky dig amid 'disgraceful' Wimbledon farce

His rivals are faced with an unenviable task, but Roger Federer couldn't help but poke fun at some of his younger opponents in the face of a farcical situation at Wimbledon.

Federer is awaiting the outcome of the match between Daniil Medvedev and Hubert Hurkacz to find out who he will face in the quarter finals.

'NOT RIGHT': Ash Barty caught in 'disgraceful' Wimbledon furore

Play between Medvedev and Hurkacz got underway overnight on Monday, but play was suspended due to rain and will resume on Tuesday with Medvedev leading 6-2, 6-7 (2/7), 6-3, 3-4.

The delay is a cruel blow to both players, with the winner set to face a fully rested Federer on Wednesday - just a day after the resumed match is completed.

Fans were already raging that the World No.2 was forced to play on the outside court without a roof, and they were left incensed when play was suspended on Monday.

Despite Centre Court (with a roof) being free after Federer's match and around two hours left before the 11pm curfew, officials decided not to move the Medvedev match in order to complete it.

Federer was asked about the decision in his post-match interview, calling it "unfair".

"It is not fair for anyone," he said.

"I have been in these situations before - but these guys are young and they can recover.

"Unfortunately they are very, very good too, so hopefully it rains again tomorrow... I'm kidding, I'm kidding!"

Fans were left seething on social media, with many labelling the decision not to move Medvedev's match indoors a "disgrace".

Some pointed out that Wimbledon officials have moved matches onto Centre Court in the past due to rain or bad light on outside courts.

At 39 years old, Federer became the oldest man in the modern era to win through to the top eight of the tournament thanks to his straight-sets win over Italy's Sonego.

Federer wins through to 58th Grand Slam quarter final

The Swiss, who will turn 40 next month, was deadlocked at 5-5 in the first set when a torrential downpour on Monday sent the players back into the locker room with Sonego down break point.

The 20-minute disruption, during which the roof was closed over a soggy and windswept Centre Court, did Sonego no favours. He immediately produced a double fault under the floodlights to surrender his serve.

That provided Federer with the spark he needed to motor through the rest of the contest after converting only two of the nine break points he had earned during the first set.

When Federer faces either Medvedev or Hurkacz, it will mark the 58th time in his career that he has contested at grand slam quarter final.

Novak Djokovic reached his 12th Wimbledon quarter-final on Monday to pull even with Arthur Gore, who had a 117-year head start, while a parade of newcomers also made the final eight.

First-timers on the men's side included Canadian Denis Shapovalov, Italian Matteo Berrettini, Marton Fucsovics of Hungary and Russian Karen Khachanov, who won a bizarre fifth set to beat American Sebastian Korda on his 21st birthday.

Djokovic, the two-time defending champion, held every service game to tie Gore and beat No.17 Cristian Garin, 6-2 6-4 6-2.

Three-time champion Gore first played Wimbledon in 1888. Djokovic made his debut in 2005, and they share third place on the men's all-time list for most men's quarter-final berths, behind Roger Federer's 18 and Jimmy Connors' 14.

"It's a privilege to break records in the sport that I truly love," Djokovic said. "I'm devoted to this sport as much as I think anybody out there on the tour. I just try to do my best."
