Well you never know, Deb. Now he has the set!

4-1 and in Zverev's favour. Magic!!! Keep it up Sasha!

Well done, Zverev, Nite Aileen.

Such a roar goes up when Denis strikes again. I'm beginning to fall asleep over the keyboard so I may go back to bed at the end of this set;think there might be a third.

Not much to choose between them at the moment. Shapovalov has upped his game a bit but there are still those unforced errors to contend with. The match is anybody's at the moment.

Its the numerous unforced errors from Denis which could be his undoing. These will probably fade as his game matures but they are many at the moment.

Set 1 to Sascha. Got a feeling he will be the winner here and I think he will have a better chance against Fed tomorrow, a match which is at a reasonable time of 8 p.m. on Sky.

Zverev breaks! Could be the set too.

Denis holds! If all games are this long we are going to be here some time.

Evening Aileen.  Hope I can stay awake for this clash of the Titans who are off to a good start it seems.

Enjoy, ladies.  I'm not a night owl, unless it's Andy playing, in which case I force myself!  I'd like to see Denis win also, so give a shout out on my behalf! 

Will do, Elly. My nights are very broken up sometimes, more's the pity. At least this week there's tennis and Aileen of course.

I wasn't interested in watching the Zverev/Anderson match, but Denis plays Alexander next, which could be very interesting!
Start time not before 1am BST, so another one for night owls like me.

Aileen, that's just about the time I wake up and can't go back to sleep. If that happens tonight, I'll join you on MW, it looks as if it could be a very good match.

Watching the young Canadian, Shapovalov, play del Porto. Plenty of support in the crowd for their young man, only 18 I believe, but del Porto always a favourite for me.

I'm routing for Cilic. He's won the American Open if I'm not mistaken and he played well against Muller who knocked out Nadal. Nice guy too. Anybody but Fed, he's had it too many times, it's someone else's turn if Andy can't have it. Probably won't get through the semis but you never know.

Yes indeed. I too hope he rests and gets lasting treatment, Aileen. Thankyou too Nigel, excellent report. Andy will always be a very special person to us all.
