Here we go, then. Rafael Nadal is serving for the first set.

Andy Murray has been talking about his Wimbledon campaign which came to end with defeat alongside Serena Williams in the mixed doubles.

"I think I achieved a lot," he said. "Considering the lack of matches, I did OK. The most positive thing is that my body felt good. My hip anyway was feeling good, so that was positive."There's a lot of physical work now trying to get stronger and to get a good balance with all the muscles around my hip.

"I think I'm doing some physical testing next week. I did some pre-Queen's. It will be interesting to see what's happened these last four weeks where I've been obviously playing tennis but doing not much training, to see how things have progressed or not."Then I'll do four to six weeks of training. Then I'll have some testing done after that again. Hopefully, I will have progressed again. But I've still got, like I said, quite a long way to go."

Another great serve from Nishikori to send Federer out wide - the Swiss player returns long.

Saved again.

Aaaand another ace.

Two more and Querrey holds.

Must be nice having a 138 mph serve to rely on when times are tough.

Another break point for Federer!!!

The eyes of the world are watching us...

Federer is increasing pressure on the returns. But his record of challenging continues - it's abysmal!

They then sang: "He's Back"*

Deuce.

*They didn't

Another set point, another ace.

Oopsie. A double fault gives Nadal another set point.

As Hall and Oates once sang: "He's Gone"*

Two break points.

*It was actually She's Gone

Querrey saves the first set point with an ace (obvs) and the second with a serve and volley.

This is ridiculous. Nadal challenges Querrey's serve and it's out by millimetres. The Spaniard did the same earlier. He's been gifted with telescopic eyesight as well as epic tennis skills it seems. Some people have all the luck.

Nadal takes advantage of the second serve and has two set points.

The first serve percentage for Federer has increased and he is winning the points easily now.

Nishikori is trying something different - I like it, it keeps the opponent guessing, what's he going to do next?

That Federer service game flashed by the eyes of Nishikori.

It even included a double fault.

The pressure is back on the eighth seed.

That escalated from Nadal not losing a point on his serve to break point quite quickly.

The Spaniard stumbles with another double fault, but Querrey spins a backhand into the net and his glimmer of opportunity has fizzled out. Nadal holds.

Nishikori is once again made to work hard for his hold.

But hold he does.

Another huge serve and Querrey's return is long. Back to deuce.

Querrey hits winner after winner at Nadal and he just keeps getting them back. Eventually the American finds an angle even Nadal can't chase down to get to deuce.

Then Querrey hits a winning volley. Break point.
