Murray 6-2 4-4 Tsitsipas*
Andy Murray is rolling back the years! He sprints in from the baseline to nail a forehand back at Tsitsipas, which the Greek can only deflect into the net for 15-30.
It gets even better for Murray. Two break points!

There is a lack of intensity from Tsitsipas.
He holding his service games because he is a good server but he is not even trying to get into the return games.
Murray 6-2 4-4 Tsitsipas*
Tsitsipas gets on the board but Murray is too far in front and takes the game. Who will blink first in set two?
*Murray 6-2 3-4 Tsitsipas
It's a case of same again for Andy Murray, as he seeks another straightforward hold to set up another shot at the Tsitsipas serve.
And it's so far, so good. Murray continues his good serving to move 40-0 ahead.

Over to you, Tsitsipas. It's a hold to love for Andy Murray to make it 3-3 in the second set.
*Murray 6-2 2-3 Tsitsipas
No such trouble for Murray, as yet, in this service game.
After a couple of misses from Tsitsipas, a blistering ace down the middle makes it 40-0.

Tsitsipas is serving well now and playing with authority.
*Murray 6-2 2-3 Tsitsipas
After all that hard work from Murray, it's another rapid hold to love for Tsitsipas as he looks to immediately put the pressure back on the Briton.

And he gets it!
Facing two break points, Murray battles back impressively to hold.

It is starting to feel like an important game this.
*Murray 6-2 1-2 Tsitsipas
Tsitsipas is denied the first opportunity as a Murray ace flies past him - and he's forced into the net on the second break point. To deuce we go.
*Murray 6-2 1-2 Tsitsipas
Luck is on Tsitsipas' side as a backhand from the Greek clips the top of the net and drops out of Murray's reach.
That sets up two break points...

Simon Bell: This looks like the old (young) Andy Murray.

At Wimbledon there was not this intensity. Andy was mentally there but his body was letting him down.
He still looks fresh and he is moving around really well.
*Murray 6-2 1-2 Tsitsipas
That's really nicely done by Andy Murray. He wrongfoots Stefanos Tsitsipas with a backhand down the line for 15-0.
Tsitsipas responds with a cheeky drop volley at the net, though.

David Melton: I think Murray will need to get this done in three.
Chris Doherty: I'm counting four misshits/double hits already by Tsitsipas and most seem to be on his backhand. Not surprised Murray is focusing on that side.
Francesca Gunn: I want to be confident with Andy but Tsitsipas always takes a set or two before he settles… but c'mon Andy!!
*Murray 6-2 1-2 Tsitsipas
Tsitsipas gets things started on serve with an ace, and after a couple of Murray misses another ace seals back-to-back love holds for the Greek in this second set. He's beginning to settle into this.

A closer game. It felt like Tsitsipas was getting a little bit more in the rally and trying to do something a bit different.
Interesting times.
