Troicki immediately dismisses the break point with a fine serve. But Murray wins it back with a delicious drop shot.

And what a lob this is from Murray - lashings of top spin, from one corner to the other. The Brit is a break up.

"This is a perfect warm-up for the final later on if Murray can get through this match in two sets."

We seem to be getting through the warm-up fine. It's Troicki's left shoulder which is giving him grief, so it shouldn't affect the serve. They're back out of their seats and away we go...

"The sun might not quite be splitting the trees in west London but it's clear overhead and set to stay that way, so we'll take it. A line of gentleman offering tickets greets new arrivals at Barons Court tube and there are plenty of slightly bleary-eyed spectators through the gates for this early start.

"Troicki has just been out having a gentle hit and Murray will have had to set his alarm a little earlier for the journey in from his Surrey home. The Briton has already won twice in a day this year, seeing off Lukas Rosol and Roberto Bautista Agut in Munich last month, so a double shift should hold no fears."

So apparently Troicki's shoulder "popped out and back in again". You might need a couple of ibuprofen after that.

That's encouraged you to regale us with hideous tales of shoulder injuries.

Phil Shotton: I have seen a guy pop his shoulder back in on his own whilst playing Sunday morning football. It can happen.

Clobovlog: A dislocation can come out and then go back in. It happened to me - my shoulder popped out twice and went back in twice.

Stop this, stop it now.

How would you fancy double duty on a Sunday afternoon? Feel up to the task?

Let us know your thoughts on the action at Queen's, send us your pictures and tell us where you're watching.

"You can't play Andy Murray and beat him unless you are 100%. It's difficult to know how bad Troicki's injury is. He went into shock when it happened. He was saved by the rain and not by the bell."

We pick up the semi-final at 3-3 in the first set. The last piece of action last night was Viktor Troicki going off to receive treatment to a shoulder injury after a fall.

The 29-year-old Serb, ranked 25th in the world, did come back out, and was about to serve against a Murray break point, before the heavens opened. So that's where we start up again, with Murray looking to go a break up.

Although, I've just seen some shots of Troicki having a warm-up swing. He does not look happy and is hitting backhands single-handed (he's conventionally a double-hander). This could end up being the shortest live text commentary in history...

It actually looks like we're going to get something in between the two in West Kensington. I'm no meteorologist, but all of those little cloud icons don't have little wet drops coming out of the bottom of them - and that's a good thing.

Double duty. Twice the fun. Two times the effort.

If Andy Murray is going to win the Aegon Championships at Queen's Club today, he's going to have to play (almost) two matches in one day. His opponent Viktor Troicki also faces that prospect, if he's to lift the title.

Kevin 'Big Kev' Anderson awaits the winner in the final, which will not be before 14:25 BST.

They get underway at 11:00 BST, at 3-3 in the first set and Murray on break point.

But first of all, let's talk about the weather...
