Fist pump - first set in the bag in 32 minutes.

Muguruza's 'helper' Conchita Martinez yelps in delight then settles back into her neutral emotion pose.

A huge exhale from Djokovic. He's landed a double fault to waste one match point.

That was lovely play from the back of the court by Kuznetsova - she was the conductor and... er... Muguruza was her instrument on the string?!

Andy Murray's next opponent, American Sam Querrey has been around between the showers, though, and looks very cheerful ahead of Wednesday's quarter-final. He's not giving too much away, though...

Q: "How are you feeling, Sam?"

A: "Average, but that's good for me."

Another hold for Djokovic, after another game featuring more intense baseline rallies.

The Centre Court crowd have been given an extra treat today with this match.

But it could be all over very soon.

Crikey!

A game which became a baseline battle finishes with Kuznetsova going long with a forehand. She's been broken to love. Not nice.

That was far too easy for the Spaniard.

Muguruza could go back into the top 10 with a win here - no doubt, she'd also like to win Wimbledon.

Yikes!

Garbine Muguruza faces break point in her second service game, but she saves.

The 2015 finalist is finding it a tad bit difficult to get over the line in this deuce battle, but she's helped out by an over-zealous backhand swipe from her opponent.

Former player and Fed Cup captain Conchita Martinez, who is helping the Spaniard during the tournament, looks concerned - but possibly she has the same expression when things are going well.

Anyway, it's all going to serve.

Plenty going on now the rain has stopped and the covers are off, including Jamie Murray in mixed doubles action with Martina Hingis on court two.

Take your pick here.

Andy Murray was not short of intensity when he was on court and hitting balls in his practice session at Aorangi Park this morning but, off it, he was looking very relaxed. The rain definitely wasn't bothering him as he strolled back to the locker room.

How's about a second serve ace to get us going, followed by a forehand winner down the line?

Done.

Djokovic then miscues a forehand for 30-15, before Mannarino nets.
