It ain't half hot mum!

-- With temperatures up to 33 degrees at Wimbledon on Saturday, ball boys and ball girls, or BBGs as they are known at the All England Club, have had their on-court shifts cut from one hour to 45 minutes.

"They also wear hats which cover the back of their necks and ears. They keep well-hydrated," explained Sarah Goldson, the ball boys and ball girls manager.

There are also 'spares' on hand who take the place of any boy or girl feeling unwell in the heatwave.

"Some courts are hotter than others so with spares, we can rotate quickly."

Run for cover

-- As well as the heat, ball boys and ball girls have to be pretty nimble on their feet, especially when big servers Nick Kyrgios and Milos Raonic are around.

Two youngsters have been hit this week by a couple of missiles but Goldson says they are trained to get out of the way.

"We have training with players who hit the ball hard and those who don't serve it as hard as others," she said.

"They are aware they need to get out of the way. It's rare to get hit although it's not great when it happens.

"But they know they need to get out of the way as quickly as possible."

In the ink

-- Alex De Minaur, who faced Rafael Nadal on Centre Court, revealed the number 109 tattooed on his chest. It was to mark his selection as the 109th player to Australia's Davis Cup team.

Zero points

-- France's Benoit Paire wasn't happy the umpire in his defeat to Juan Martin del Potro on Court Two, claiming the official wasn't doing his job effectively.

"Zero is because when you stay on the chair and you don't make an overrule and you just announce the score, I think I can do the job. So we don't need one chair umpire if it's just to stay and say the score. Because for me, he has to do his job, he has to take some risk, he has to make some overrule," he explained.

- Who's saying what -

"This year, I was trying to enjoy, not just tennis, but life, the food like strawberries and cream, the burgers and lobster, all the shops. When you play singles and doubles, I need to find tiny time to run out to get all these foods."

-- Hsieh Su-Wei after her shock win over world number one Simona Halep

"I was young and I was a little bit stupid."

-- Benoit Paire on why he once said he hated playing at Wimbledon

"It's just incredible his physicality. That's probably what shocked me the most, just his presence. You watch him on TV, and you can't really appreciate how hard he hits every single ball and how much intensity and just brute force goes into every one of his ground strokes."

-- Alex De Minaur on Nadal after losing in straight sets to the world number one

"This chair umpire mistake in the benefit of Kyle Edmund vs Novak is a top3 if all times. Triple mistake on the same point ! The ball doubled, it is out and the racquet of Kyle hit the net. Still he got the point and saved a break point this way."

-- Serena Williams's coach Patrick Mouratoglou tweeting on the 'double bounce' controversy that robbed Djokovic of a break in the fourth set of his clash with the British player.

"I felt like somebody unplugged me in the fourth set."

-- Alexander Zverev after his loss to Ernests Gulbis

- Royal Box watch -

Bumper day in the best seats as the middle Saturday sees a host of sports stars and members of the armed forces honoured.

He was joined by star golfers Sergio Garcia and Matt Kuchar, Olympic gold medallists Mo Farah, Jessica Ennis-Hill and Nicola Adams and boxers Carl Froch and David Haye.

Li Na, Billie Jean King and Rod Laver were on hand to represent tennis.
