Djokovic has done a Houdini in that game.
*Millman 0-1 Murray
A pretty routine opening hold of serve for Andy Murray as he closes out with a dead-eyed ace down the middle.
John Millman was just waving that one on its way as he lunged left in vain.
Lois Savage: Djokovic doesn't look right to me..but I am not expert.
Niall Griffiths: Sam Querrey wins the Jordan Henderson Look-A-Like competition hands down

Djokovic 6-7 1-6 6-3 2-2 Querrey*
This isn't pretty at the moment. Djokovic mis-hits, Querrey mis-hits. It's all over the shop.
The American hits long and Djokovic saves two break points to win the game. A proverbial get out of jail free card for the Serb.
Millman 0-0 *Murray
Andy Murray to serve first, here we go.
John Millman is a Liverpool supporter.
"I think on my dad's side of the family, they're all (Manchester) United supporters, and the team they hate the most is Liverpool. So being an annoying little six-year-old, you probably go against the team they hate the most," he said as he explained his Anfield allegiance.
"Since then, football is probably growing in Australia, and the amount of travel that I have done since I finished school, you see just how big the game is. Yeah, I'm a very passionate Liverpool supporter. And I love Jurgen Klopp."
Djokovic 6-7 1-6 6-3 1-2 Querrey*
A fantastic dropshot from Sam Querrey completely out-foxes Novak Djokovic and the American moves to 15-30.
But then he shanks a forehand. That was ugly.
But wait...break point Querrey. Ah, no. It's gone. The 28-year-old returns into the net on Djokovic's second serve.
Deuce time.
Millman v Murray
John Millman, a 27-year-old who is up to 67th in the world after battling back after shoulder surgery, has played Andy Murray once before.
The Aussie took it to three sets, but was undone 6-1 5-7 6-3 in Brisbane in 2013.

Querrey certainly hanging in. It's not often in the big events you see Djokovic with 11 break points and only taking two of them.

All the heat now coming from the world number one, all the break points and pressure on Querrey. Novak's coach Boris Becker, a golden bear of a man in the players' box, nods his ursine head in approval.
*Djokovic 6-7 1-6 6-3 1-2 Querrey
Novak Djokovic ends up in a heap on the floor as he tries to get on the end of a huge Sam Querrey serve. Looks like a hard landing for the Serb, but he appears to be ok.
Querrey has now saved four break points in this game, and he moves to advantage.
Then he serves an ace to seal the game.
Millman v Murray
John Millman has been located.
The Australian puffs his cheeks out as he strides out on court with Andy Murray looking loose and limber as he follows in his wake.
The Centre Court crowd give a rousing reception to the greatest Briton.
Millman v Murray
The line judges are in place, the ball kids are standing to attention, but apparently we are missing one John Millman.
Sue Barker informs BBC One viewers that the Australian has gone Awol behind the scenes.
The Australian was probably lured outside by the rare appearance of that giant mysterious golden orb in the sky.
*Djokovic 6-7 1-6 6-3 1-1 Querrey
Three straight points for the world number one and he moves to break point.
A nifty little forehand winner from Sam Querrey saves it for now, but then he hits wide in an erratic manner. Another break point.
This time the American saves it with an ace. Back to deuce.
Djokovic 6-7 1-6 6-3 1-1 Querrey*
Annnd we're back on again.
No time for a quick knock. We're back under way straight away on Court One.
This weather is off the hook.
The shower was brief, the sun is back out and the covers are off.
Right, after the latest round of hokey-cokey, I think we are ready to see some tennis on Centre - with Andy Murray v John Millman - and around the grounds.
The tennis journalists at the All England Club are earning their weather stripes.
