Anderson takes a rare lead against the serve, but Murray scuppers that with an ace down the middle that hits the padding at the back with a satisfying thud.

Anderson's eyes light up on a serve that pitches up, he winds up, optimistic, and slices his backhand wide. Murray makes a good challenge to go 40-15 and hen a backhand rally comes to an end when Anderson floats into the net.

"Murray has been hitting the ball well for several months now, his success on Europe's clay courts honing the groundstrokes and the switch to grass apparently not proving too tricky. Anderson is predictably strong on first serve but

"Murray has pounced on any second serves, grabbing the fleeting chances that can come and go on grass."

"Get down! get down!" shouts Andy Murray. Who either is in the mood for dancing, or is imploring himself to get lower to the ground on those baseline shots.

More big serves from Big Kev and a love hold.

We're not getting the rallies and intricate tennis we saw earlier in the Troicki match. Aside from Murray's break in the first set, each man's serve has looked pretty safe. Anderson particularly looks unlikely to make an indent on the Murray serve.

Anderson has faced adversity at Queen's already this week - he survived being match points down against Lleyton Hewitt in the first round. Can he find a way to throw Murray off his stride?

Big Kev goes 30-0 up, but Murray is all over a second serve and then finishes off with a backhand to put the pressure on.

Anderson holds though with, you guessed it, an ace.

Helen Kingman: I personally find the constant aces by Anderson boring, that's not what I want to watch

Grant Rolland: You wouldn't think Andy had played earlier, such an athlete.

Murray puts in a couple of good serves himself. But the highlight is a slice backhand that drops on the line and almost bananas back on itself there's so much spin. It's the shot that wins the set for the Brit.

Speaking of which, there are four big serves and an easy hold for Anderson.

This has come from an anonymous texter, but I liked the story

I was once on a tennis holiday in Spain. Kevin Anderson was there on a training camp at the same time so I cheekily asked if I could face a couple of serves. Being a very nice guy he said "yes" and promptly sent down a couple of second service bombs with such incredible spin they bounced right over my head. Never even got a racket on them.

There are rallies threatening to break out at times, but they generally end with Anderson undoing himself at the baseline. The final point is a sweet serve and forehand combo from Murray for a love game.

"Murray looks like he's got plenty of time, he's reading the ball, seeing it early and playing it so well. It looks like the only way he'll get into any trouble is if he loses concentration."

Anderson needed that game. The trusty serve sees him through and that's 100 aces for the tournament. Amazing.

"It's amazing how Murray has gained such control of this match so quickly. He's able to hit every shot and he's looked the winner of this tournament for quite some time. He's the man."

Big Kev won't be used to this. He can play the groundstrokes, and is obviously decent at getting around, but he definitely won't match Murray on those fronts.

Murray is confident. He disguises a backhand drop shot as a backhand drive. Anderson has no idea where it's going.

And Murray holds with a charging cross-court forehand dished up with a load of lovely top spin.

"A 141mph serve would knock the racquet out of most people's hands but Murray got it back and made Anderson play. Anderson will be amazed he got it back."

Andy Murray gets a sniff from a great return, putting it on Anderson's toes. It allows Murray to whip a forehand winner to the corner. Murray is simply making Anderson play the shots, and it works again to go 15-30.

And what about that backhand? Murray winds up and releases to Anderson's left and it's not coming back.

Anderson, angry, slams a 141mph serve. But Murray returns and Anderson, rattled, pops the volley into the net.

Tom, Whitstable: Looking for Omens anyone? In 2013 Murray had won 2 titles by this stage, including a Masters. Then he won Queens and Wimbledon. In 2015, Murray has so far won 2 titles including a Masters, so if he wins today, history repeating itself remains on track

Neil: There is that aura around Murray again like at the Olympics. He looks so calm and confident. Can't see him being beaten

Murray pulls ahead to 30-0 but Anderson gets his big frame down to an attempted pass down the line to go 30-30 - Murray slips in .his attempt to reach it.

A 96mph serve from Murray does the business (Anderson serves above 110mph by the way). And Anderson spoons from the baseline to end what threatened to be a rally.

Murray gets back the first Anderson serve, but can't get to the subsequent volley.

Murray sitting really deep on Big Kev's serve but then stepping in at the last second, changing Anderson's perspective between the toss up and contact.

Murray has returned all three serves so far, but just one point to show for it. And we have Anderson's first ace. And then another. Game held.

Breaking news. Andy Murray has been chased by an insect.

The Scot does very well not to swing at it with his racquet. Instead, he stays calm and nudges it away. Although he's still a little apprehensive about it returning.

Murray reminds Anderson that he's not the only one with a decent serve. The South African fails to return four of them and it's a comfortable start for Murray.
