It was a day filled with plenty of twists and turns at Wimbledon that was headlined by two major upsets – Rafael Nadal and top seed Angelique Kerber’s exit. Roger Federer, meanwhile, moved into the quarter-finals of the competition for the 15th time.

Roger marches on, Nadal crashes out in a thriller

Rafael Nadal suffered fresh Wimbledon misery on Monday as the two-time champion crashed to a stunning 6-3, 6-4, 3-6, 4-6, 15-13 fourth round defeat against Luxembourg’s Gilles Muller. Earlier, the match see-sawed with Muller getting the better of Nadal by taking a two-sets-to-love lead. But, the resilient Spaniard powered through in the third and fourth sets to take the match into the fifth set.

Muller, seeded 16th, will make his first Wimbledon quarter-final appearance against former US Open champion Marin Cilic. Meanwhile, Federer’s search for an unprecedented eight Wimbledon crown was well and truly alive as he outclassed Grigor Dimitrov 6-4, 6-2, 6-4 to reach his 50th Grand Slam quarter-final.

Federer will face Canada’s Milos Raonic, the sixth seed for a place in the semi-finals. Raonic, the 2016 runner-up, reached the Wimbledon quarter-finals on Monday with a 4-6, 7-5, 4-6, 7-5, 6-1 win over Germany’s Zverev.

Kerber’s poor season continues, Halep closes in on becoming No 1

Angelique Kerber crashed out of Wimbledon and lost her hold on the world No 1 ranking as the German was beaten 4-6, 6-4, 6-4 by Spain’s Garbine Muguruza. In the course of the highly-entertaining, two-hour-18-minute match, where Muguruza came up with 55 winners, Kerber only managed to reply with 27 of her own.

Second seeded Simona Halep ended Victoria Azarenka’s hopes of becoming the first mother in 37 years to win Wimbledon with a 7-6(3), 6-2 fourth round victory on Monday.

Nadal’s nasty tryst with a doorframe

Rafael Nadal bashed his head on a doorframe as he prepared to step onto court. The Spaniard bent down to fix his shoelaces then jumped up – unfortunately right in the doorway – only to crack his head. He fell about laughing with opponent Gilles Muller before their marathon match.

Scarf to the rescue

– As the epic encounter between Nadal and Muller went past the 10-10 point in the final set, the low setting sun was reflecting off a panel into server Nadal’s eyes. The umpire asked for the fans in front of it to stand up but eventually a woman’s scarf was draped over it.
