In best of three I would absolutely back Andy but two more is a lot more of a toll physically.
It gives Tsitsipas more time to get himself in the match. They've never played against each other and I think a lot of the youngsters have grown up watching Andy but it is very different actually taking him on, especially when he's playing this well.
I think this set is going to be a lot closer.
*Murray 6-2 0-1 Tsitsipas
It's a double fault for Andy Murray on his opening point.
He misses with a wide first serve on the next, but Tsitsipas is audibly frustrated as a poor shot takes the pressure off Murray for now.

Tom Kirkham: Yes good start Andy Murray. Come on!
*Murray 6-2 0-1 Tsitsipas
A flying start to the second set by Stefanos Tsitsipas.
The third seed lands two aces on his way to a comfortable hold to love.

The first-serve percentage is 64% but Andy looks so dominant on the first ball after that.
He is trying to play really aggressive. Tsitsipas is maybe a bit too far behind the baseline to do real damage in the rally.
Andy is trying to move forward a bit more than usual to close out the point at the net.
It is not what we expected at all. I'll take more of this thank you very much.
Watson 1-6 0-0 Juvan
Britain's Heather Watson is not having such a good time over on court 10.
She's just lost the first set 1-6 to Slovenia's Kaja Juvan.
In happier news Harriet Dart - who won the first-set tie-break against France's Caroline Garcia - has just broken back to get back on serve at 2-2 in the second set.

Murray is so fired up.
He knew he had to get a really good start here and he has come out so prepared, so energised,

What a phenomenal start by Andy Murray.
Murray 6-2 0-0 Tsitsipas
But Andy Murray gets the job done!
What a first set that was from the current world number 114.
Plenty for Stefanos Tsitsipas to think about.
*Murray 5-2 Tsitsipas
Tsitsipas forces deuce to get his first real opportunity to apply some pressure to the Murray serve.
The Greek saves another set point with a stunning lob which lands perfectly on the baseline. The third seed certainly isn't finished in the first set.
*Murray 5-2 Tsitsipas
This time, Tsitsipas comes out on top at the end of a great point, forcing Murray to chase out wide before finishing things off at the net for 30-30.
Murray isn't fazed at all, and responds by working Tstsipas around the court before closing in to execute a delicate winner.
Set point.

Tsitsipas has been so inconsistent from the back of the court.
Andy is playing well but I think he could even play better than this.
*Murray 5-2 Tsitsipas
A couple of errors from Tsitsipas put Murray within two points of the set, but Murray hits a backhand into the tramlines for 30-15...
*Murray 5-2 Tsitsipas
He looks very, very good Stuie. Stefanos Tsitsipas has yet to really get going, so it'll be interesting to see what happens if or when he does...

Stuie Neale: Andy looks good here
*Murray 5-2 Tsitsipas
A confidence-boosting hold to love for third seed Stefanos Tsitsipas, but it's a long way back from here.
Andy Murray will serve for the set.
Murray 5-1 Tsitsipas*
Tsitsipas slaps a forehand into the net as Murray moves to 40-0, before the Greek gets on the board as Murray just misses the baseline.
That's as good as it gets for Tsitsipas, who nets once more, and Murray is one game from the opening set.
Laura Robson
Former British number one on BBC Radio 5 Live Sports Extra
I've been surprised at the level Andy has come out with. I am equally surprised at how Tsitsipas has come out.
He has not looked like he's mentally there yet. I thought this was going to be the other way round.
We can never rule Andy out but over the last few weeks I have not seen this level from him.
If he can sustain this, we will be very happy British tennis fans.
*Murray 4-1 Tsitsipas
Sharp is certainly the word.
Andy Murray appears to be moving effortlessly around the court, and with a great turn of speed when required.
He's about to serve for a 5-1 lead.
