*Draper 6-7 (3-7) 6-3 3-6 7-5 3-3 Kokkinakis
Three big points in a row to stop Thanasi Kokkinakis' momentum and hush the Melbourne crowd.
But he can't get the hold over the line as Kokkinakis comes up with a blazing backhand that squeezes past Draper at the net. Deuce.

The first time I've seen in Thanasi Kokkinakis smile in quite a few hours. It's unbelievable, the defence from Jack Draper, the attacking from Kokkinakis.

It just had to happen to these two guys, it was always going to go to five [sets] and it was always going to be a killer for the one that came out on the wrong end of it.

Thanasi Kokkinakis was making a real show of his painful shoulder right in front of Jack Draper's coaching team in between games there.
I wonder if he's trying to use that to his advantage and playing some mind games with the British number one.
It certainly looks that way as he gets the better of Draper and opens up a 0-30 lead with a brilliant overhead at the net.

Jack Draper has got a swagger to his step as he wrongfoots Thanasi Kokkinakis with a piercing forehand down the line.
The Australian, meanwhile, looks exhausted when he wins the next point with an equally brilliant winner. 30-15.
Draper 6-7 (3-7) 6-3 3-6 7-5 3-2 Kokkinakis*
Winner after winner after winner for Jack Draper. All Thanasi Kokkinakis can do is throw his racquet in a wild attempt to reach the ball.
A short and sweet service game for the 23-year-old. He'll want to keep it that way.
*Draper 6-7 (3-7) 6-3 3-6 7-5 2-2 Kokkinakis
Thanasi Kokkinakis, somehow, is still going. He's been struggling physically from the very start but he's still making this very difficult for Jack Draper, working the Briton hard around the court.
That earns him the hold and even more love from the crowd on John Cain Arena.

Jack Draper is maintaining a solid level of tennis right now, not going crazy in rally mode, not trying to blast winners.
*Draper 6-7 (3-7) 6-3 3-6 7-5 2-1 Kokkinakis
We're officially past the four-hour mark now and we're no closer to finding a winner.
Jack Draper has found his forehand and he powerfully fires two winners past his Australian opponent on his way to the hold.
He gets his nose in front, but we're still on serve as things stand.

I can only imagine the pain and the damage of what it will be like when he [Thanasi Kokkinakis] wakes up tomorrow morning, win or lose.
*Draper 6-7 (3-7) 6-3 3-6 7-5 1-1 Kokkinakis
Jack Draper is on a roll, while Thanasi Kokkinakis seems to be slowing down.
Rather than celebrating his service hold, he gives a big grimace and an angry yell towards his coaching team. That looked like a real struggle.
Draper 6-7 (3-7) 6-3 3-6 7-5 1-0 Kokkinakis*
Cool, calm and collected from Jack Draper. A solid service game ended with a delicate drop shot that Thanasi Kokkinakis has absolutely no chance of reaching.
*Draper 6-7 (3-7) 6-3 3-6 7-5 0-0 Kokkinakis
A reminder that both of these players needed more than four hours to win their first-round matches, and they're going to need the same again today.
The clock has struck 11pm in Melbourne and we're fast approaching the four-hour mark.

The reactions of Thanasi Kokkinakis are starting to slow up, he's not alert when the return comes back into play, there is some sloppy footwork causing some of these errors.
*Draper 6-7 (3-7) 6-3 3-6 7-5 0-0 Kokkinakis
Thanasi Kokkinakis looks a bit peeved off with the umpire.
Jack Draper has left the court for a bathroom break and the Australian wants to receive some treatment on that shoulder problem that has been bothering him, but the umpire tells him that must happen at the change of ends.
He shakes his head, annoyed, before going over to talk tactics with his coaching team.
*Draper 6-7 (3-7) 6-3 3-6 7-5 0-0 Kokkinakis
Against the odds, we go to a fifth set! Jack Draper looks like he's got a new sense of confidence and he lifts his hand aloft in celebration as Thanasi Kokkinakis goes wide on the second set point.
We've got a real match on our hands now. Draper has made this very exciting indeed.

Thanasi Kokkinakis has lost his way slightly. Another miss hands Jack Draper two set points.

This will be pretty special if Jack Draper can force a fifth set here. He looked down and out not long ago.
Two misses from Thanasi Kokkinakis open up a 0-30 lead for the British number one.

This time last year Jacob Fearnley was ranked 646th in the world, but he now reaches a Grand Slam third round for the first time in his career.
Draper 6-7 (3-7) 6-3 3-6 6-5 Kokkinakis*
Jack Draper is clinging on for dear life but the serve comes up clutch and he places the pressure back on Thanasi Kokkinakis, who will now serve to stay in the set and force a tie-break.
