A blink-and-you'll-miss-it service game from Kyle Edmund. He holds to love.

Alex Ward has a lot of work to do here.

Kyle Edmund boshes a whipped forehand past Alex Ward to move to 0-30. It was a nice finish, if a little too close for comfort on the line.

The world number 50 earns three break points to put the pressure on Ward, and the wildcard sends a forehand wide.

Hmm, Del Potro continues to serve well to get to 40-15 but then double faults, the second one a foot fault that leaves the Argentinian utterly nonplussed.

That call seems to have rattled him. And this won't help - a Kokkinakis forehand that is going out clatters into the net cord and spins back in.

JMDP puts all his frustration into a forehand to get the advantage then crashes another forehand winner to hold. Brutal.

This is a 90-minute practice drill for Andy Murray and he is not holding back - banging down some big serves as part of a chip-and-charge drill with his practice partner, then switching to scuttling around the baseline after returning some deliveries from coach Jamie Delgado.

The assembled snappers looking on have been voicing their concern about his hip after watching him hobble about a bit, but the intensity and length of today's session, after his match on Monday, back up what Murray himself is saying - that he feels better and it is not causing him any significant problems.

Alex Ward has hustled his way back into this, taking on Edmund and forcing his opponent to slap a forehand wide.

That brings up break point, but Edmund chucks some extra spin onto a backhand and Ward nets. Boo.

Now it's Ward that goes long, bringing up a set point, and he'll take the second set!

Many tennis players like to be in a constant dialogue with their box during matches. Not Alex Ward. Probably because he doesn't have a main coach.

Any fist pumps by the 27-year-old from Northampton towards the stand may then be dedicated towards mum Sue.

Sue is beaming as she watches her boy, knowing that win or lose it will be a 60th birthday for her to remember.

Better from Kokkinakis, reeling off a comfortable service game as Del Potro couldn't really get near him.

He needs to follow up these holds with a break soon, though.

So it's all level in the second set on court two but the first was pretty much all Juan Martin del Potro.

The Argentinian showed craft, class, power and touch to get the better of the young Aussie Thanasi Kokkinakis.

The British snappers on Aorangi have a choice of who to aim their cameras at now because Johanna Konta has arrived for her practice session, on the court adjacent to Andy Murray's.

It cannot be often that two British number ones play next to each other as if they were hitting balls down the local park (albeit a local park with some very nice grass courts) but it is Murray's movement, or slight lack of it, which is getting most of the attention at the moment. Konta has also had injury problems, of course, but she is gliding around effortlessly.

Kyle Edmund, a game away from the second set, crouches and slaps two winners beyond Alex Ward.

Deuce comes up as Ward slaps into the net and shouts "come on!" at himself. His energy has just slipped a tad, but that's a magnificent way to bring up the advantage with a big forehand that bounces just on the line.

He'll hold, but Edmund will serve for the set.

Kokkinakis had started to get after the Del Potro serve but JMDP is shutting that down now as he eases out to 40-0.

OK, that's good from the Aussie as he passes for 40-15. Oh, that's gorgeous from the Aussie as he whips a winner cross court.

Damage was done earlier though and Del Potro gets the point he needs to hold.

As Ferrer takes the set 6-3, he and Gasquet deliver a 'wonderful' rally.

With Kyle Edmund, he has weapons in his game but doesn't have a Plan B or Plan C - he doesn't defend well. He is good when he is aggressive but, particularly when he's losing matches, he looks brittle. He has to learn to defend better, have a presence on the court. It's not that he doesn't try but he seems to accept it sometimes when a result doesn't go his way or is being outplayed, rather than trying something different.

Andre Agassi is watching on from up on one of the balconies. He's having to shift now, though - the sun's got in his eyes.

Twice Edmund gets his nose in front, twice Ward thrashes his way back into contention.

A shovel of a shot is long from Ward, though, and Edmund backs up his break with an ace to hold.

Del Potro uses all his craft to move 0-30 on the Kokkinakis serve but the Aussie's serve is on point right now - two aces get it back to 30-30 and an unreturned boomer makes it 40-30.

But a woeful attempted drop shot makes it deuce. His serving continues to save him, though. Advantage Kokkinakis and an ace by the thinnest of margins sees him hold.

Edmund bounces on the balls of his feet before slicing in a backhand that wrong-foots Ward. Ward's response? A stinging serve that Edmund lackadaisically slaps wide.

Winner down the line now from Ward, drawing the oohs of the crowd, but Edmund brings up his first break point as Ward sails a backhand into the net.

Can he take it? Yup - a superb low backhand, completely beating Ward, and that's the break Edmund needed.

Lovely touch from Del Potro to work Kokkinakis all around the court and finish with a deft volley.

Grace followed by power as he crashes another thumping forehand winner. Then a big, unreturned backhand sees Del Potro hold.

My old school teacher always said that the first game of the second set was the most important of the entire match. Important hold for Kokkinakis.
