Eugenie Bouchard's surprise victory over Ana Ivanovic, the No 12 seed, meant that both the women behind last year's surprise Gangnam-style YouTube hit are still strutting their stuff on the grass. Bouchard and her best friend on tour, Laura Robson, both 19 and born less than a month apart, persuaded the likes of Maria Sharapova and Jo Wilfried Tsonga to take part in the video that has now had nearly 375,000 views.

Referee gets his knickers in a twist

Never mind the spate of injuries, pants was the issue of day three. Roger Federer may not be allowed to sport coloured soles to his trainers but Wimbledon rules state undergarments, as the regulations term them, can be any colour of the player's choosing so long as they are "covered" when the player is standing. Alizé Cornet sported red "hot pants" during her second-round victory without catching the referee's eye.

Nice to see you, to see you nice

An eclectic gathering in the royal box: double Olympic gold medallist Mo Farah – who took his father-in-law as his guest – Stephen Fry, Sir Bruce Forsyth and the daily Middleton, this time two for the price of one with Mr and Mrs in attendance.

Spotted: The man who bans women

Also up in the royal box was Peter Dawson, the chief executive of the Royal and Ancient, which sees nothing wrong in holding the Open at a club that will not accept women members. Wimbledon has admitted them since day one in 1868. "I totally believe in equality, but I also believe there are times when men need to socialise with men and women with women," says Dawson.

Weather watch

Dry and intermittent sunshine, with rain arriving in the evening. Maximum temp 19C.
