Sensational! Thiem digs himself out of a hole by sticking with Tsitsipas and forcing him into an error.
Thiem clenches his fist, Tsitsipas berates himself. Back on serve!

BBC Sport at the O2 ArenaI've no idea who the crowd are cheering for anymore. It's a mix of both names but what I can tell you is it is very, very loud.

Well, Tsitsipas goes 0-15 behind before a hefty first serve down the middle unsettles Thiem and after a couple of exchanges he knocks a forehand long for 15-15.
Tsitsipas glides forward to push Thiem wide and deep, finishing off the point with a carefully-watched overhead.
A 30-15 lead turns into a 40-15 one for the Greek when Thiem overcooks another forehand from the baseline.
Thiem nails a punched crosscourt forehand for 40-30, then goes long - again - to hand over the game.

This is the point where Thiem ambushed Zverev yesterday in the first set of their semi-final. I'm not expecting a similar choke from Tsitsipas...

Groans and an anxious look from Team Thiem as their man coughs up a double fault for 15-15. Hmmm. The Austrian resets quickly though and gets back into the groove, wrapping up another hold with an ace. Danger averted.
Over to you again, Stefanos...

An ace gets Tsitsipas off to the perfect start, a second serve out wide hit long by Thiem makes it 30-0.
First serve in, another point won. And again. Tidy, very tidy. He's won 88% of first service points in this set.
