"Miomir's on fire, Draper's looking terrified!"

The Serbs are not singing that as Freed From Desire is blasted out by the DJ at the end of the set - but it'd have been funny if they had.

Well, funny for them - not for the Brits.

I think right now just dig in and compete, which is of course something that comes easy to Jack Draper. You just have to lift that energy. It's not easy when you've played your heart out for an hour and you have nothing to show for it.

Well you can't really ask for more than that.

Draper quickly forgets that opening set and digs in to hold his opening service game to love.

A few encouraging words from Leon Smith in the ear of Jack Draper at the break.

The young Brit did not play badly in that opener but it was a consistent performance from Kecmanovic.

Brilliant from Kecmanovic to come into the net and set up the winner.

Draper looks disappointed with that as Serbia take an important lead.

Better from Draper to win the point on his serve.

But no! He double faults again and puts the set in sight for Kecmanovic.

5-2.

Oh no.

Superb ball-striking from Kecmanovic and Draper finds himself quickly on the backfoot.

4-1.

These nervewracking moments at the business end of a set is where the captains earn their corn, particularly with a couple of young(ish) players.

Britain's Leon Smith goes for his usual relaxed demeanour, legs crossed and arms on the bench as some smoothing words try to coax the best out of his young charge.

Serbian counterpart Viktor Troicki is stood like Liam Gallagher - arms behind his back and bending over like he's using Kecmanovic's face as a microphone.

One team will be feeling Supersonic after this tie-break...

Kecmanovic starts well to take the point on his serve then seems to put Draper off by challenging a call. It works and the Serb gets himself a mini-break up.

A superb rally from the baseline sees Draper come out on top in the point and he's on the board in the tie-break.

2-1.

Perfectly held by Draper. It's been a gripping contest and no surprise that we're heading to a tie break in this opening set.

This has been a gripping contest with very few frills.

Been more about knocking seven bells out of the ball rather than flicks of finesse.

But the guile Draper showed to save the first set point could prove key.

That illustrated his current levels of confidence and he kept his nerve again to wear Kecmanovic down on the second.

Nobody in this arena can confidently claim to know which way this pivotal opening set will go.

Kecmanovic still hasn't flinched.

Draper will have to serve to stay in the set.

A glorious passing shot from Draper takes us to 30-30 on the Kecmanovic serve and the Brit is not going away.

He's playing some really good tennis. But so is the Serb.

Brilliant from Draper to win the rally and keep himself in this set.

The Brit is really having to dig in here.

A big serve and that is a crucial, crucial hold. He was on the brink of losing the set but battled back for the hold.

What a shot under the most extreme of pressures! An incredible time to produce the backhand dropshot. Jack Draper knew exactly where he wanted to place it.

An equally sumptuous shot from Draper's backhand saves set point but the Brit sends a forehand wide to take us back to deuce.

Draper challenged the call but no luck this time.

It looks like Draper has got his service game well under control but lets Kecmanovic back in with a long forehand for 30-30.

An absolute beauty of a backhand from a sprinting Kecmanovic and Draper can only watch it sail past him.

Break and set point.

Miomir Kecmanovic hasn't really blinked so far. He's kept up a really high level.

Draper berates himself as he nudges his return into the net.

No hesitation from Kecmanovic in this game and he strolls to a hold to love.

The Brits weren't silenced for long!

Draper's resilience and perseverance drags him back into the game as he battles to earn a crucial hold.
