Andy Murray follows up the break with a hold to love.

The skids could be under Tomas Berdych here. His appetite for the fight needs to be keen if he to keep this on court much longer.

Sam Jamaa: The fact Murray had the mental strength to win that set after facing seven set points is exactly why he will become number one.

Jeanna Skinner: Focus now Andy. We don't need any of that losing concentration malarkey.

One break point - the first of the match - for Murray. Berdych fends him off to take it to deuce.

Here comes a second though. Into a rally. Never mind a racquet, Berdych needs a jet-washer to get Murray off court. As stubborn as week-old chewing gum and finally Berdych pushes the power meter too far, crashing into the net.

An hour and six minutes on the clock - about 15 of which were in that titanic tie-break - and Murray has a set lead and a foot on the windpipe.

Andy Murray gives us a couple of very GIF-able little moments in the opening two points.

First, he shoots some serious shade in the direction of some fan in the stands who has forgotten to turn the flash off on his phone. Absolute daggers.

On the next, Murray finds himself flopped over the netcord as he fails to apply the brakes quickly enough chasing down a drop-shot. Berdych sportingly goes to pick up the Scot's bat which has fallen out of its owner's reach on Czech territory.

Nothing apart from short video clips to take from that game though.

There are a smattering of the Murray Army in the stands.

They greet a zippy Andy Murray ace with a collective "whomph!". Their man does not look being derailed from a tie-break at the very least.

On he ploughs.
