Andy Murray delighted fans at Wimbledon with a logic-defying four-hour comeback win that ended at 10.30pm last night – while berating the umpire over the ‘dangerous’ grass on Centre Court after becoming the latest player to slip.

The three-time Grand Slam winner came back from two sets down to triumph against German opponent Oscar Otte and win his second round match in front of a delirious Centre Court crowd.

However, he also became the latest player to take a tumble in what critics are dubbing the wettest Wimbledon in a decade. 

At one point, as he chased a lob shot from his opponent, he completely lost his footing, with his left leg straightening under him and his knee seeming to hyper-extend. 

As he got back to his feet, he called out to chair umpire Aurelie Torte, telling the official the court was ‘so dangerous’.

That was his second slip of the match, after he was earlier left grabbing at his left groin following another fall – the same area he previously injured. 

He joined Novak Djokovic, Kei Nishikori, John Isner and Bianca Andreescu in slipping yesterday – a day after US tennis superstar Serena Williams was forced to retire when she fell over on Centre Court and appeared to hurt her ankle. 

Murray previously said after Miss Williams retired: ‘Brutal for @serenawilliams but centre court is extremely slippy out there. Not easy to move out there.’ 

Yet despite the fall, Murray showed true grit as he battled back from two sets down to storm his way to a stunning victory. It was almost as hard for wife Kim Sears, who went through the full range of emotions as she watched from the stands. 

It came just two days after Murray endured a similarly-gruelling four-hour first round win that had also exhausted the crowd’s emotions.

After Murray took the first set the tables soon turned, with a determined Otte snatching the second and third sets. 

In a nail-biting fourth set, Murray became the latest star to fall on Centre Court – a tense moment following the years of groin and hip injury issues that saw him take a four-year break from Wimbledon before hip surgery. 

Murray battled back to secure the fourth set 6-4 to the delight of roaring crowds who erupted into a championship-style winning cheer.

And Centre Court roared when the stubborn Scot clinched the fifth set and a ticket to the third round.   

Murray had previously said he was resigned to not having his wife and four children – Sophia, five, Edie, three, Teddy, one, and a third daughter, born in March – watching him due to the coronavirus restrictions.

But Kim was able to attend today and could be seen clapping from the stands in a floral blouse and sunglasses. 

Speaking after his victory, Murray thanked the crowd for getting him ‘fired up’ during the final sets that secured his astonishing Second Round win, admitting the clash was a ‘tough match.’

He said: ‘What an atmosphere to play in at the end, the whole crowd is amazing but there was a few guys in there who were getting me fired up and I needed everyone’s help tonight.’

The exhausted tennis ace noted that he had fallen a few times during the clash, lamenting the ‘slick courts’ that saw Serena Williams retire when she fell over on Centre Court and appeared to hurt her ankle.

He added: ‘I obviously get a rest day tomorrow the hopefully I can come out on Friday and play in another atmosphere like this, and hopefully perform well.’   

The tense clash came after tennis pros yesterday took a tumble while playing at Wimbledon for a second day after heavy rain led to slippery grass in the wettest start to the grand slam in ‘almost a decade’.

Murray and Coco Gauff were among those to comment on the surface yesterday, while eight-time Wimbledon champion Roger Federer said he had previously found the surface to be more slippery when the stadium roof was shut due to a build up of humidity. 

A Wimbledon spokesman has defended itself against criticism of its grass, claiming the club was satisfied with the quality of the surface and that it had been the wettest start to a tournament ‘in almost a decade’.

Mr Federer said this year’s problems are not new. ‘Those first two matches are always extremely difficult. But it’s always been like this,’ he said. ‘I feel for a lot of players, it’s super-key to get through those first two rounds because the grass is more slippery, it is more soft.

‘As the tournament progresses, it usually gets harder and easier to move on.’ 

In 2013, several players slipped on one day, including Maria Sharapova and Victoria Azarenka, who was left injured. The day was dubbed ‘Wacky Wednesday’ by newspapers.  

Mr Federer said he believed the Centre Court roof made the grass more slippy, saying: ‘I do feel it feels a tad more slippery maybe under the roof.

‘I don’t know if it’s just a gut feeling. You do have to move very, very carefully out there. If you push too hard in the wrong moments, you do go down. 

Analysing why this may be the case, Joseph Page of Joe’s Lawn Care told MailOnline: ‘Moisture is more likely to build up in an enclosed space, particularly with fans and players in there.

‘It’s a bit like being inside a greenhouse. However, there will be ventilation and air con in there so I couldn’t comment on the technicalities of this particular situation. 

‘The groundsmen will be assessing everything by the hour and looking after things so well.

‘You need a higher level of moisture in the turf to keep it green in the first place, so it’s always a play off between keeping the surface moist but also dry enough so the ball can bounce.’   

Federer added: ‘I do feel it feels a tad more slippery maybe under the roof. I don’t know if it’s just a gut feeling. If you push too hard in the wrong moments, you do go down.’
