This time last year, Jacob Fearnley was ranked 646 in the ATP Rankings.

He had competed in just one Challenger-level event.

But on his Australian Open debut, the world number 92 is through to round three.

"The next Andy Murray" someone in the crowd tells him as he walks around to say thank you to his supporters and sign autographs. "I don't think so," Fearnley replies.

Next up? He looks set to face world number two Alexander Zverev.

What I've picked up over the last three games is the court positioning of the young man from GB [Jack Draper], he seems to be a little tighter to the baseline so he's taking time away from Thanasi Kokkinakis.

Not yet. The crowd think it's in, but Jack Draper's clenched fist silences them. Back to deuce.

Thanasi Kokkinakis finds the line with a backhand winner, bringing up a break point.

Is Jack Draper's hard work in the last game going to go to waste?

The umpire has a real fight on her hands getting this crowd to be quiet after Jack Draper misses the slice to gift Thanasi Kokkinakis a 15-30 lead.

They're not so noisy when the Australian finds the net on the next point.

YES! Jack Draper has done it. He's levelled the set and he's made this very interesting indeed.

The British number one has had enough of this crowd, and he points to his ear and calls for some appreciation.

Where has this come from?! Jack Draper, after firing down a superb backhand winner, has got himself three break back points.

Jacob Fearnley will have two more match points on his serve!

Oooh. Two unforced errors from Thanasi Kokkinakis and Jack Draper has got himself another half chance to break back.

Arthur Cazaux digs deep to save a first match point and force Jacob Fearnley to serve this out.

What a moment for the British 23-year-old.

Here we go then. Can Thanasi Kokkinakis serve out the victory and reach the third round of his home Slam for the very first time?

Or does Jack Draper have something up his sleeve to stop the Australian?

It is perfection from Jack Draper, he has done all he can to stage and he's saying show me some appreciation for what I am doing.

You can see the nerves are creeping in for Jack Draper with that ball toss and it gets a few jeers from the crowd, who are doing their best to put the Briton off.

He's not done yet. Draper holds his hands up as Thanasi Kokkinakis fails to reach the drop shot.

Jacob Fearnley will have a first match point on Arthur Cazaux's serve!

Jacob Fearnley burst out of the blocks with a backhand winner to leave himself three points away from extending his Australian Open to a third match.

But the Briton, positioned way beyond the baseline, narrowly misses the line to bring Arthur Cazaux to 30-30.

It crowd are getting rowdy as they feel like victory is closing in for Thanasi Kokkinakis, who blasts another one of those forehand winners around the net post and in to draw level at 30-30.

And then another as he takes us to deuce.

Super impressive game from Jacob Fearnley, who recovers from a double fault to get over the line and move one game from victory.

Fearnley, making his debut at an overseas Grand Slam, is so, so close now to a place in the third round.

Boom! What about that for a second serve. Thanasi Kokkinakis is determined to give Jack Draper no second chances as he moves one game away from a place in the third round.

Draper has to stand firm here.

Jack Draper is chewing his bottom lip and is looking around wide-eyed, slightly dazed.
