SW19 Diary: Pippa leaves Barton and Co in the shade

The diary has noted before the lack of footballers at the Championships but Joey Barton came to the rescue yesterday by turning up on Centre Court – Barton's doing the English summer circuit, having been at Glastonbury last weekend.

What odds the estranged Newcastle midfielder popping up at the Henley Regatta next week? Also there to watch the men's semi-finals was Jack Wilshere, who went along with Perri Shakes-Drayton, one of Team GB's rising stars.

Read all about it: Indy's feats make Judy sit up

The name Indy de Vroome caught our eye early – there are not many competitors called after this newspaper – and she's still going. The unseeded 15-year-old from the Netherlands has reached the last four of the girls' singles and has Judy Murray tipping her for great things.

Broady raises the bar with wrong end of stick

Misunderstanding of the week. During Liam Broady's press conference he was asked what his father did for a living. "He's a landlord," said Broady. Questioner: "Will he do a free bar if you win?" Broady: "He's not that sort of landlord."
