Alex de Minaur is just not playing with the usual energy, vigour and electric pace but it may change, he may be able to work his way into this quarter-final match.

There's a look about Alex de Minaur who seems forlorn at the moment.
He's certainly not looking a figure of energy.
Jack Draper is just going about his business in the right way, head down, he's got to ignore what is going on.
A very weird start to this match, a bit clunky.
Draper 4-1 De Minaur*
While I attempt to work out what I'm watching, Jack Draper races through a far more comfortable service game than the last. The serve found the mark and he ended with a whipped forehand cross-court.
He heads to the chair by far the happier.

That's out as well!
Scattergun is the way I'd describe this from Alex de Minaur. Some of it is good. A lot is rubbish.

Draper 2-1 De Minaur*
Sloppy. Two double faults and now an unforced error off the racquet of Jack Draper.
For only the second time in the tournament he is broken, wiping out that early advantage.

Alex de Minaur has been very tentative in the early exchanges between the two of them. I don't think he looks in great shape.
Jack Draper is bringing intensity, striking into the corners and powering those forehands.
I just think that de Minaur is a little off.
