Grigor Dimitrov plonks his first serve down the centre, and Edmund nets his return!
It's all square on Rod Laver Arena, after just over an hour.

What a rally! Edmund is out of it, in it, and then wins it with a two-handed backhand that Dimitrov slaps over the baseline for 30-30.
That's a miss from Edmund though, forehand finding the net, and it's set point to Dimitrov.
*Dimitrov 4-6 5-3 Edmund
A lazy flick of the wrist, followed by a well-timed volley, help Kyle Edmund race to 40-0, before Dimitrov's one-handed backhand adds another touch of class.
Edmund chucks in a double fault of his own, before smashing over a winner in emphatic style. Dimitov will serve for the set.
Image source, ReutersJiten Chandarana: Even if this set is gone, Kyle has to start serving first in the third and try and stay ahead in the score.
Dimitrov 4-6 5-2 Edmund*
Not to get too technical, but that was a rubbish service game from Dimitrov, and yet somehow, he's managed to hold.
Can Edmund make him serve this second set out?

The level of play has dropped in the last 10 minutes and it all seems to be down to nerves. Edmund has really let Dimitrov off the hook there.
Dimitrov 4-6 5-2 Edmund*
Grigor Dimitrov is off the hook, as an Edmund forehand and then a backhand go out.
He's a game away from taking the second set.
Dimitrov 4-6 4-2 Edmund*
Saved with a decent first serve!
There's a yell from Dimitrov as he picks the right moment to nail his first serve. Deuce.
David Law
Radio 5 live commentator at Melbourne Park
This is just extraordinary. He's double-faulted for the third time in the game.
Dimitrov 4-6 4-2 Edmund*
Dimitrov can be his own worst enemy sometimes.
Another double fault, the third of the game, and here's break point to Edmund...
Dimitrov 4-6 4-2 Edmund*
Ugh. An ace from Grigor Dimitrov is book-ended by two ugly double faults - it's not quite clicking and DImitrov looks to his box in disgust.
Edmund lets him off the hook with a billowing return to a loose second serve, before Dimitrov pirouettes forward and curves a spectacular backhand down the line.
Oh, but that's a poor forehand from Dimitrov, into the net, and it's deuce!
Dominic Inglot
British doubles player on Radio 5 live at Melbourne Park
Kyle shouldn't be disincentivised to go into the net just because Dimitrov passed him there. Don't be discouraged, keep taking it to him.
*Dimitrov 4-6 4-2 Edmund
A bit of chuntering from Grigor Dimitrov as he gets pushed further towards the back of the court, and his forehand eventually flies long.
Edmund shimmies into an elegant forehand volley, before he spears a big forehand somewhere into the stands. He holds, though.

Dimitrov 4-6 4-1 Edmund*
A bit of to and fro from both players as they're pushed wide - Dimitrov draws the error out of Edmund first, before Edmund responds with a nice slice of his own.
Another attempt at the forehand down the line from Edmund, and it's another miss. It's 40-30, and Dimitrov holds after a bit of a tussle.

Tim Addicott: Edmund is playing well, I think unlucky so far in the second. Dimitrov though has stepped it up - he had too!
Dawn Third: Second set not going his way but really think Kyle could do this. Even when under pressure he keeps his cool these days. Really matured as a player over the last six months or so. Go Kyle!
*Dimitrov 4-6 3-1 Edmund
Edmund draws the error out of Dimitrov's forehand - can he make it count?
Yes he can! A slice wrongfoots Dimitrov, and he nets. Edmund holds for the first time in this set.
*Dimitrov 4-6 3-0 Edmund
Grigor Dimitrov challenges Kyle Edmund's first serve, and it's in by the tiniest of tiny margins.
So casual from Dimitov, though. He blocks Edmund's serve and the sprawling Brit can't control his return. Deuce number four arrives.
*Dimitrov 4-6 3-0 Edmund
Clever from Dimitrov, forcing Edmund to run around behind the baseline, before coming up and volleying a winner over.
A spinny backhand from Dimitrov meets Edmund's stonking forehand, and it's Dimitrov that comes off the worse. As you were.
*Dimitrov 4-6 3-0 Edmund
Strong first serve from Kyle Edmund helps his cause enormously, but another forehand is slapped over the tramlines.
Back to deuce.
