First serve out.

Murray then goes long.

15-40.

Double-break point.

One saved with a sliced drop at the net.

"What is that serve?" Murray says after he fires down an 86mph effort which Verdasco has no problems dealing with.

Verdasco then produces the point of the match with a unbelievable topspin lob after chasing down Murray's forehand.

15-30.

Murray seals as 'Dasco's double-handed backhand comes off the post.

Murray's fitness was always better than 95 percent of the players, but today that may be a different scenario. It will be interesting to see how he holds up.

No messing from Cameron Norrie, who consolidates the break with a quick hold of serve - the British number two takes a 4-1 lead in 17 minutes in the second set.

30-30.

30-40.

Murray has break point thanks to the computer that calls Verdasco shot wide.

This is Abraham the NYPD dog. He’s lovely and just before this picture jumped up to say hello to me. Plenty of police presence every day at the tennis. Today the dogs have lots of rests and extra water.

What a great point between the pair. The Spaniard pulls out a stunning backhand smash that Murray chases down only for his opponent to pump back.

15-0.

15-15.

The Spaniard then goes wild with a forehand and then mutters to himself again.

15-30.

Ninth seed Dominic Thiem has completed his fightback, whizzing through the fifth set against Steve Johnson to book his place in the third round. Spending more than three and a half hours on court in this heat will have taken it out of the Austrian though.

A quick exchange of holds at the start of the second set, before Cameron Norrie steams to three break points - and only needs one!

Dusan Lajovic rattles a forehand into the tape, and the Brit gets the breakthrough in the second.

Plenty of shade inside Ashe - except for the upper tier of the stand opposite the chair umpire.

Unsurprisingly that area is sparse. Those sat there are, almost to a person, wearing a hat. Sensible folk.

30-0.

Verdasco then sneaks a topspin forehand down the line.

30-15.

40-15.

Then Murray booms down his third ace of the match.

We're still on serve.

Ice towels await.

40-0.

Followed by a stunning forehand by Verdasco to seal.

We've rushed through these two opening games of the second set.

How about a rally guys? I know it's hot.

Verdasco appears to be basking in having taken the first set as Murray eases to 30-0.

Murray then makes his fourth double fault.

The Scot keeps his cool - yes, not like that in this heat - to fire an ace down the T to hold.

Did I say earlier it didn't actually feel that hot sat courtside on Ashe? An hour later the beads of sweat are dripping.

Both players simultaneously whip off their shirts at the changeover, timing which Gaz, Dave and Horse would have been delighted with in the Full Monty.

No change of shorts, however...

Cameron Norrie fends off three set points to scramble back to deuce, but eventually Dusan Lajovi prevails with the first set in 33 minutes.

The Serb takes it 6-2. Work to do for the British number two.

'Dasco saves.

Deuce.

Advantage Spaniard.

Another attempt at a flat forehand at the net Fernando? He makes it.

First blood Verdasco.

'Dacso again looks for a wide-angled slapped forehand winner, but it clips the net and loops wide.

Break point for Murray.

30-40.

The looks to his box, where wife Kim and mum Judy are sat with his coaching team, are getting longer and more intense from Murray as he battles to stay in the set.
