Andy Murray vs Cameron Norrie live: Score and latest updates from the Cincinnati Open

You feel as though Norrie has the slight advantage going into this deciding set. Murray serves first and opens up with a double fault, not the best start. 

Off his second serve Murray then hits a passive forehand and Norrie can pounce with a blistering forehand winner to make it 0-30. Murray is then on second serve next point but he's much more positive with his groundstrokes and earns his first point of the final set. A drop shot followed by volley gets him to parity at 30-30. 

Two points later it's deuce and Murray, as has been the pattern the past few of his service games, is again under pressure. A forehand, hit with some force, into the net earns Murray a service point prompting him to scream out loud. He then holds after another long rally. He's really being made to work hard now.

Norrie is serving for the set and backed into a corner Murray hits out to some effect. A fine forehand return gets him to 0-30 and a point later the two-time Wimbledon champion has three break points. 

Norrie saves the first thanks to a strong first serve, a long forehand from Murray saves him the second, and great power allied to precision culminating in a forehand smashed winner saves Norrie the third. 

The British No 1 is looking far more confident as two aces take us to a deciding set. 

Much better from Norrie BUT Murray had his chances to break at least twice that set. 

Murray is angry with himself after an unforced error - a wayward backhand - allows Norrie into the game at 30-30 having been 30-0 up.  He is under more pressure this set and a big Norrie forehand winner makes it deuce two points later. He's knocking on the door once again, and a brilliant return earns the British No 1 another break point. Another unforced error - a wide sliced backhand - gifts Norrie the break and Murray will be frustrated with himself. 

Norrie breaks. 

Good hold from the British No.1, he holds to 15 and is looing good in this second set. 

For the first time since the break in the opening game of the match Murray is under pressure on his serve with Norrie having a break point at advantage. You feel as though the momentum is with the world No.11 BUT Murray comes up with a big first serve and it's back to deuce - that's a fantastic response. That is undone by a forehand into the net and Norrie has another break point, can he make this one count? No, he cannot as he hits a forehand long - a surprising miss. 

From there Murray digs deep and holds, just...

Murray is within sight of another break point at 0-30 but two wayward backhands - one long, the other into the net - gets Norrie back into the game.

From there a backhand winner down the line and and cute drop shot, that Murray did well to get to, allows the world No 11 to hold to 30. That was a good comeback from Norrie, but once again at 0-30 up and with Norrie on second serve, Murray may be thinking of what might have been...

Norrie is standing further back on his returns of serve and it's paying dividends at 30-30. Murray then gets in a big first serve and shouts on winning the point. It's as though he realises Norrie has gone up a gear this set. 

The next point see Norrie move well around the court, moving Murray about before a forehand smash makes it deuce. 

Murray is keeping his intensity up and wins the game with an ace. That was a battling hold from the two-time Wimbledon winner. 

Three unusual errors in a row from Murray helps Norrie to a 40-0 lead and in the blink of an eye it's a love hold. 

Good confident stuff from Murray. That was as straightforward a service game you can get (bar firing down four aces). He holds to love. 

Norrie is 40-15 up when with most of the court open he decides to play a drop shot that goes wide - he's overcomplicating things at the moment. 

Murray again comes into the net to play two great volleys the second of which wins him the point to get it to deuce. 

A forehand Murray winner saves one service point and at deuce for a second time a wide forehand from Norrie gives Murray a break point. Then, considering the volleys he's pulled off today, Murray misses the easiest net shot he's had today. That would have got him the early break...

Norrie - thanks to a forehand winner and a long Murray backhand - then wins the next two points and holds. 

Could that missed Murray volley prove significant? 

Norrie doesn't look as though he's swinging freely and that's playing into Murray's hands. He plays one great forehand winner that is noteworthy because it stands alone as one of the few forehands that's come right out the middle of Norrie's racquet. 

He is, however, a battler and gets it to deuce in this game - aided, in part, by some poor Murray first serves. But Murray holds firm and takes the next two points to win the set 6-3. 

That was impressive by the three-time grand slam winner. He's moving well, serving well and playing an astute tactical match. 

As for Norrie it looks as though he's just a bit too tentative.

Murray has been quick to come into the net so far - at 0-15 here he attacks the net and plays a great, sliced volley on the run to make it 0-30. 

Norrie, however, gets his first going and fights back well to get to 40-30. At that moment Murray again uses the sliced backhand before volleying for the point - he really is moving well, a good sign for the veteran (I am allowed to call him that, no?!). 

At deuce an unforced Norrie error gifts Murray a break point and it's all he needs as next point the world No 11 comes into the net and is passed brilliantly by Murray who plays a wonderful backhand crosscourt winner. 

That was vintage Murray and all the signs are good for the Scottish star so far. He'll now be serving for the first set. 

Murray uses the sliced backhand well setting up a volley which gets him to 15-0. That's followed up with an ace. He's looking good and doing what he needs to do against one of the form players this year. He holds to 15 and looks in a confident mood. 

Solid from Norrie as he holds to love. 

Norrie isn't going to overpower anyone but what he lacks in power he makes up for with a delicate touch. At 15-15 the world No 11 comes into the net and plays a delightful drop volley that would have flummoxed almost everyone. Murray, though, is opening up his shoulders and holds to 30. He's looking strong out there and confident to boot. 

It's been a fascinating encounter so far, Murray's first serve and forehand speed are both working well. 

Thanks Rob for stepping onto the blog from the swimming pool that is currently Lord's...panic over, was a false alarm at Telegraph Towers and I am back in front of this British battle. 

The good Murray response from the early break looks as though it's going to be capitalised on as the Scot has two break points at 15-40. Norrie is struggling with the conditions and on second serve Murray can attack the world No 11. But after a long rally, in which the Scot seemed on top, Murray hits long and is down to one break point. That's saved by Norrie thanks to a good first serve. 

From deuce the world No 11 recovers well taking the next two points and we're all square. 

After all that breaking palaver, Murray holds to 30, Norrie's two points coming off a double fault and a lob that tested Murray's ability, or rather his hip's ability to turn quickly and chase it back to the baseline from the net. 

Deft, running backhand drop by Murray ties it up at 15-all. Norrie's first serve isn't all that reliable either so far and he hooks a forehand cross off his second serve long after being pushed back by Murray's withering backhand. 

Norrie makes it 30-all, defending the attempted pass at the net with a neat drop volley to earn game point but Murray takes it to deuce after a fine baseline rally ends with a blistering forehand crosscourt winner.

Murray gives himself the chance of an immediate breakback with whippy power, drawing the error. Can Norrie defend the break point on his second serve? No, he plants a running forehand into the net and Murray breaks back quam celerrime.

Break back.

Norrie takes an immediate love-15 lead rather fortuitously with a framed forehand that loops over Murray and kisses the line. Up goes a hand in apology. Murray, wearing a blue and yellow short, double faults to make it 15-30, double faults with his second serve by quite a long way but follows it up with a good, wide serve to level it up at 3--all.

Murray's first serve isn't functioning and he invites Norrie into the net and he earns a break point off a flukey net cord. 

Murray can't defend the break point off his second serve and powers his second shot of the point into the net.

Break of serve.

Rob Bagchi here, stepping into the breach during a Lord's rain delay. 

Norrie has won the toss and elected to bat receive.

There's a fire alarm at Telegraph Towers and I have to make a swift departure. Back with all the action ASAP! 

And we're not far from the opening game of this all-British encounter.

Have only faced each other once before on the ATP Tour and it's Murray who won that encounter. It came in 2019 in Beijing with the Scot winning in three sets. 

But it's Norrie who goes into this clash as favourite. He's the world No 11 (to Murray's current ranking of 47) and has two titles this year to the all-time great's none. 

Here's what Murray had to say about his opponent ahead of today's match. 

"Cam's one of the best in the world and I want to beat him."

In Cincinnati. Blue skies and temperatures approaching 30 degrees later on. Delightful...

Let's have a quick look at last night's battle of the US Open winners - or in other words Emma Raducanu's impressive win over Serena Williams. 

It was easily Raducanu's most composed and authoritative performance since her memorable win at Flushing Meadows, and, hopefully, will prove to be a confidence-boosting victory. She goes against Victoria Azarenka in what should prove to be a tough encounter. 

But it was a night that really belonged to Serena Williams - for many the GOAT...For Serena fans it was a tough watch with the 23-time grand clam winner in the home straight of her remarkable career. 

Here's a good read from Fiona Tomas on what is likely not to be a fairytale ending to Serena's brilliant career.

Andy Murray is expecting no shocks when he faces compatriot Cameron Norrie at the Western & Southern Open in Cincinnati today. 

The two Britons face each other in the second round of the Masters tournament after both were taken to gruelling three-setters by foes new and old. 

Three-time grand slam champion and Duracell Bunny Murray survived a thrilling encounter with long-time rival Stan Wawrinka. The Scot showed a lot of courage and grit, two characteristics he's shown in spades throughout his career, in the deciding set, battling back from an early break to ultimately claim victory 7-6 (5), 4-6, 6-4.

That's set up a Battle of Britain with him facing the world No 11 and British No 1 Norrie. And knowing each other well, Murray is predicting no surprises out on court today. 

"He is very different to how Stan plays, being a lefty," Murray said. "[He's] flat on the backhand, heavy topspin on the forehand. We have spent a little bit of time on the court together, so there won't be many surprises out there for me."

One thing Murray may be concerned about was the toughness and physicality of his win over Wawrinka. 

"The court is pretty lively when the weather is like this. Physically I feel tired," he said.

"I had some issues with cramp during the match, the same as Washington, so that is something I need to get on top of.

"I tried to take the ball on a little more and finish points at the net. I wasn't that successful when I came up, but the intention was there. I was a little more offensive on the second-serve return. Last game I was just fighting, trying to find a way through."

Norrie booked his place in the round of 32 contest after eventually coming through his match against rising star Holger Rune.

The world No 11's path to victory mirrored Murray's as he ultimately overcame his teenage opponent 7-6 (5),4-6, 6-4.

Stay here for all the action from what is likely to be a hugely intriguing clash between the two Brits.
