Thiem 2-6 4-6 6-4 1-0 Zverev*
The Austrian is bounding about the court like a kid on the hunt for Easter eggs.
An easy hold.
*Thiem 2-6 4-6 6-4 Zverev
He does. Hope restored.
We've been here before and know what happens - will it happen again?
Thiem 2-6 4-6 5-4 Zverev*
Two set points as Zverev's sliced backhand finds the net.
Wow!
Can he? Will he?
Thiem 2-6 4-6 5-4 Zverev*
Thiem hands three racquets over to his team in the stands. For the raffle?
Can he break with the one he's holding?

It's been a very flat, very difficult match, it's been almost painful viewing watching Zverev pummel through Thiem.
Thiem 2-6 4-6 5-4 Zverev*
Thiem holds - Zverev must now hold to stay in the set.
An altogether new type of pressure for the German.
*Thiem 2-6 4-6 4-4 Zverev
Zverev's double hander from the back drifts long leaving the Austrian to wrap up this service game.
Keeping in trend with this match, the game goes to deuce as Thiem's backhand drifts into the net.
Deuce.
*Thiem 2-6 4-6 4-4 Zverev
Thiem 30-15 up produces a wayward forehand and then looks at his tool - that wasn't at fault Dom.
30-30.
Annabel Croft
Former British number one on BBC Radio 5 Live
It really is now or never for Dominic Thiem. He can't afford any let-up here.
*Thiem 2-6 4-6 4-4 Zverev
A 126mph second serve and a Thiem forehand that lands long does the trick for the fifth seed.
Nothing separating them in this set.
Thiem 2-6 4-6 4-3 Zverev*
40-15 and it all seems routine until the German produces a double fault.
OK, what now?
Thiem produces a outstanding whipped backhand volley - phenomenal reactions from the Austrian.
Deuce.
Thiem 2-6 4-6 4-3 Zverev*
An ace to open up his service game. No tension in that arm.
Zverev's shot then lands out, although it needed verification from Hawk Eye. 15s each.
Thiem 2-6 4-6 4-3 Zverev*
Thiem eventually holds as Zverev's attempt at a forehand down the line fails even to find the blue of the court inside the Arthur Ashe stadium.
It'll be back.
*Thiem 2-6 4-6 3-3 Zverev
An easy forehand winner at the net and it's 40-30.
Hold?
Not yet as Thiem's looping forehand lands wide of the target.
It's that time again - deuce
*Thiem 2-6 4-6 3-3 Zverev
Thiem's range-finder appears faulty again. The techies need to fix it.
Fixed as a winner and forehand error from Zverev pulls up 30-30.
Annabel Croft
Former British number one on BBC Radio 5 Live
Zverev hasn't panicked. He is standing up to the increased level at the other end of the court.
*Thiem 2-6 4-6 3-3 Zverev
A beautiful forehand half volley sees Thiem stretching as he races to the ball.
The highlight of a relatively easy hold.
Zverev lets out an internal sigh of relief.

Don Wimble: Annabel is spot-on about Zverev's serve - better to go big and miss rather than decelerate and miss a dribbler.
Solomon ibn Gabirol: Zverev is not exactly my cup of tea, but I hope he wins this US Open. Thiem will definitely win a Grand Slam pretty soon too!
Thiem 2-6 4-6 2-3 Zverev*
Thiem races through his own service game to put the pressure back on Zverev.
Can the German hold his game together? He needs a solid hold now, not a shaky one.
Annabel Croft
Former British number one on BBC Radio 5 Live
Zverev is just starting to breath a bit more, there's a bit more tension and he's starting to have to work a bit harder.
Thiem is starting to gain in stature and confidence and it's starting to look a bit different.
