Lopez daren't sit down too much at the changeovers. Perhaps, after spending almost eight hours on court in the past 24 hours, he thinks his ageing body might seize up.

The Spaniard took his shirt off in the singles final to reveal some tape on his back and is not moving too sprightly between points now.

That doesn't stop him whacking a thumping forehand winner to bring up those break points...

Lopez gives Murray a wry look as Ram hits the ball at him and he cannot return.

"Let's go!" roars Murray as Salisbury's ball lands long.

Back on serve.

Salisbury double faults. Serving for a set against Andy Murray is quite a big ask, to be fair.

You can see Feliciano is walking very stiffly - every time the ball takes a bad bounce it is not going to be easy.

Salisbury steps up to serve for the set. Lopez returns the ball straight at the Brit's feet to take a 15-0 lead.

But Ram pops a backhand in between Lopez and Murray on the next point to even things up.

Lopez continues to opt to stay standing at the changeover. He must be stiffening up badly now. Only another hour or so to go Feli...

Salisbury can do nothing with a steamroller of a serve from Lopez and the Spaniard holds.

A fan is falling asleep in the stands. Someone tell him this is Murray's big return!

The fairytale may soon be back on track.

Murray hits a return long, but again Lopez saves the day when it's his turn to receive. The Spaniard hits the ball at Ram to win the point.

Lopez isn't sitting down at the changeover, instead bending over in a stretch. Is he worried if he sits down he'll never get up again?
