Hello and welcome to LIVE updates of the first of our semi finals from the 2020 ATP Tour finals. It’s world number one, Novak Djokovic against US Open champion, Dominic Thiem. It’s a repeat of this year’s epic Australian Open final and should be a cracker.

ATP STATS: Only two players have defeated Djokovic, Rafael Nadal and Roger Federer at least five times each. Thiem : 5-7 vs. Djokovic, 6-9 vs. Nadal, 5-2 vs. Federer.

Andy Murray: 11-25 vs. Djokovic, 7-17 vs. Nadal, 11-14 vs. Federer.

GAME, SET AND MATCH! - DJOKOVIC 5-7 7-6 6-7 THIEM. What a turn around! Thiem rampages back from 0-4 down in the tie break to take it 7-5 on his sixth match point. The Austrian pounded away at Djokovic with a stupendous number of winners and reaches the final after a two hour and 54 minute epic.

Tie break latest: Thiem kicks off with a double fault and gives himself a mountain to climb. He then blows a forehand long but grabs a mini break back with one that lands in. It’s 4-2 to the world number one at the change of ends.

DJOKOVIC 5-7 7-6 6-6 THIEM. Domi corks a trademark backhand down the line which would have had the crowd on its feet if there was one! It’s the best he can muster in trying to nick it at the death as Nole leans on the old faithful of his serve to take us into a tie-break decider.

DJOKOVIC 5-7 7-6 5-6 THIEM. The Austrian will be happy to get out of that one unscathed. He dumps two forehands into the net for 30-30 and then Djoker has a good look at the return of serve, but blows it. Cue an outpouring of anger as he berates himself in Serbian. It doesn’t help as he leaks another crosscourt forehand seconds later to ensure Thiem is guaranteed another tie break at worst.

DJOKOVIC 5-7 7-6 5-5 THIEM. The No.3 seed benefits from a huge slice of luck when another blockbusting shot cannons into the net and bobbles over. It could unsettle Novak at 15-15 – but it doesn’t. The five-time winner hits a clean crosscourt winner off the forehand to seal a relatively routine hold.

DJOKOVIC 5-7 7-6 4-5 THIEM. A quite sensational Djokovic backhand down the line earns a ‘bravo’ from Thiem. The Serb looks keen on the break, but can’t get a look-in from 30-30 as a 10th ace sets up Domi to stay ahead. No margin for error for the Serbinator from here.

DJOKOVIC 5-7 7-6 4-4 THIEM. First sign of any real danger for the server. Djokovic fires just long to dangle deuce in front of his opponent. He pulls some funny faces in response but finds some big serves to snatch the hope away.

DJOKOVIC 5-7 7-6 3-4 THIEM. Now then. Thiem registers his 42nd winner with a delicate drop shot before Djokovic tries to finally up the ante. He has the point on his racket for 30-30 but blows another volley at the net. A service winner then seals the hold as we enter the business end of the set.

DJOKOVIC 5-7 7-6 3-3 THIEM. The US Open champion can’t do much on the return and Djokovic reaches parity in the blink of an eye.

DJOKOVIC 5-7 7-6 2-3 THIEM. The Dominator continues to, er, dominate most of the rallies. He moves way past the 30-mark for winners to eek his nose in front once more. Djoker has shown amazing defence at times, but if Thiem hits a purple patch, no one can really live with that type of hitting. Credit to the world number one that he’s very much in with a chance of winning this.

DJOKOVIC 5-7 7-6 2-2 THIEM. It’s almost like the players are saving themselves in this early spell of sparring. The top seed gets outfoxed by a delightfully angled volley at the net, but it’s the only blow Thiem can land. All square.

DJOKOVIC 5-7 7-6 1-2 THIEM. The serving procession continues, though Thiem does enjoy unloading that crisp forehand as he takes the game for the loss of one point.

DJOKOVIC 5-7 7-6 1-1 THIEM. Djokovic retorts with his own comfy hold to 15. Very much the calm before the storm.

DJOKOVIC 5-7 7-6 0-1 THIEM. That’s a highly impressive response to the major disappointment of that tie break. Thiem serves big and hits big off that forehand to kick the decider off with a statement of a love hold.

SET! - DJOKOVIC 5-7 7-6 THIEM. We are going the distance! Thiem has four match points, but can’t get over the line. The world number three drills a backhand into the net on Nole’s second set point and the Serb snares it 12-10. Amazing drama!
