Fantastic from Jack Draper.
An ace saves the first and he comes in behind a brutal forehand to put away a volley at the net for the second.
Deuce.

Alex de Minaur is going nowhere.
A Jack Draper backhand lands in the net for 15-30 and a double fault hands the Australian two break back points...

He's got it!
Alex de Minaur saves the first but Jack Draper then runs around a ball on the backhand side to hammer a forehand winner down the line.
Superb. A semi-final place just got that much closer...

Nothing to worry about for Jack Draper.
That big serve comes to the fore again to make it 40-30 and he finishes it off from there.

Brilliant from Alex de Minaur.
Incredible speed from the Aussie to race in to meet a Jack Draper volley, flicking it down the line for a winner.
30-30 and half a chance for the 10th seed.

He just looks so subdued.

Jack Draper has really put pressure on the Alex de Minaur serve in the match.
But it's been relatively straightforward for the Aussie so far in the third. An ace secures the hold to 15.
'De Minaur yet to reach a Grand Slam semi-final'published at 20:50 British Summer Time 4 September

David Law
Commentator on BBC Radio 5 Live and BBC SoundsAlex de Minaur is yet to reach a Grand Slam semi-final at the age of 25 and he has never won a tennis match from two sets to love down before.
That's what he has got to do today if he is to beat Jack Draper and go to the last four of the US Open.

A couple of big serves and then Alex de Minaur finds the net.
Solid hold for Jack Draper to get himself up and running in this set.

It was all rather odd at the start but it feels like a proper quarter-final now.
Jack Draper did superbly to keep his composure after Alex de Minaur came back at him in the second set.
The Aussie looks far more comfortable now but has he left himself too much to do? We'll see but he starts the third with a comfortable hold.

Jack Draper changes his shirt. He rearranges his shaggy hair.
Can he pull this off? Sam Drury is here to take you through the rest.
Enjoy.

Annabel Croft
Former British number one on BBC Radio 5 Live and BBC SoundsI love Jack Draper's attitude on the court. He's not getting too hyped up when he is hitting great winners.
He is just methodical how he is going about it.
That could have been a potentially tricky banana skin he was up against in that second set but he came through it with flying colours in 57 minutes.

The serve pushes Alex de Minaur out wide and then he stays nerveless under a tricky backhand volley.
He's two sets to the good in his first Grand Slam quarter-final!

Jack Draper plays like a man way beyond his 22 years to wrestle back the momentum in this match.
He will now serve for the second set having had a whole lot of Aussie grit thrown his way in the past 15 minutes.
