Hello and welcome to LIVE updates of the final of the 2020 ATP tour finals. It’s the world number three against the world number four as US Open winner Dominic Thiem locks horns with the in-form Daniil Medvedev. Let’s hope for a blockbusting show as London bids farewell to the season-ending finale.

GAME, SET AND MATCH!– MEDVEDEV 4-6 7-6 6-4 THIEM. The comeback kid does it again. Medvedev hits back from a set down, just like he did against Rafael Nadal, to claim the biggest title of his career to-date. The Russian serves it out to 30 on his first match point after a brilliant two hour and 42 minute final against the US Open champion. It proves to be another disappointment for Thiem, who must make do with being the runner-up for the second straight year.

MEDVEDEV 4-6 7-6 5-4 THIEM. Big credit to Thiem again. He looks shattered, but unloads a succession of backhands to turn a 15-30 dilemma into a cracking hold. He poses the serve-out question. Will Medvedev keep his nerve?

MEDVEDEV 4-6 7-6 5-3 THIEM. It’s looking good for Daniil. He chalks up a superb love hold with another foray into the net and is one game away from the title.

MEDVEDEV 4-6 7-6 4-3 THIEM. Domi stays in touch with a morale-boosting love hold, but needs to find something special now with his energy levels clearly dropping.

MEDVEDEV 4-6 7-6 4-2 THIEM. That’s really disappointing for Thiem. He scorches a crosscourt return to make deuce from 40-15 down. Clutch serving puts Daniil back in front, but then Domi misses a clear-cut pass to allow the Muscovite to consolidate.

Ninth time lucky and all of that...

BREAK! – MEDVEDEV 4-6 7-6 3-2 THIEM. Wow. That was some game of tennis. Thiem shows incredible defiance to fend off two more break points, but this time the Russian refuses to be denied. He makes a surprise dart into the net on the third and beautifully volleys away a winner.

MEDVEDEV 4-6 7-6 2-2 THIEM. No such drama for Daniil. He swaggers to a quick-fire love hold.

MEDVEDEV 4-6 7-6 1-2 THIEM. The Bear tears through what looks like a sloppy service game from the Austrian to tee up triple break point. A near miss on a fizzing return and a brave second serve from Thiem see the No.3 seed save all of them. Clutch play from there helps the US Open champion somehow dig his way out of trouble.

MEDVEDEV 4-6 7-6 1-1 THIEM. Lots of gesturing and glances at his corner from Thiem. He’s not thinking as clearly as he was following that tie-break blow and Medvedev’s adaptability and mid-game tactical shifting is reaping some reward. All square early in the decider.

MEDVEDEV 4-6 7-6 0-1 THIEM. Close! Medvedev drills a backhand up the line that narrowly misses the baseline. It would have given him two break points. Thiem gleefully takes the let off but still has to come through a couple of lung-bursting rallies to earn his hold.

SET! – MEDVEDEV 4-6 7-6 THIEM. We are heading into a decider. Medvedev hits back from 2-0 down in the tie break to claim seven points on the spin and keep his dream of winning this trophy alive.

Tie break latest: Thiem races 2-0 up but just misses a forehand up the line on the run. Medvedev surges back and it’s 4-2 to the Russian at the change of ends.

MEDVEDEV 4-6 6-6 THIEM. No danger there. The US Open champion eases to a hold to 15 and he’ll now hope for more tie break joy that would see him land this title.

MEDVEDEV 4-6 6-5 THIEM. Nervy moments for Medvedev as he turns anxiously to see a Thiem lob drop just long at 15-15. An ace and a top-class serve and volley get him through and he’s guaranteed the tie break if Thiem holds his nerve next.
