Murray loses that game as Djokovic levels at two games all in the deciding set - but his level of commitment is unparalleled. The Scot approaches the net for a shot most players would have given up on - and very nearly makes it!
Andy Murray is appearing to get angrier as time passes - a brilliant player, but the errors appear to be getting to him. Djokovic, meanwhile, has appeared to be fairly calm throughout, but like Murray, focused on the task.
This may just be an ATP250 event - meaning, for the uninitiated, that the winner gains 250 points. So it's not much by way of actual scores, but all the prestige and more is at stake here. And it's exactly how both Djokovic and Sir Murray are playing.
For a minute there, it almost looked like Djokovic could break Murray. Perhaps the best rally of the match so far with 29 shots in all! Murray, Djokovic, both scrambling and making some promising shots, but a wide return from Djokovic gives Murray the game. 3-3.
And that's the first game to Novak Djokovic. A lot of long tough rallies there, and Djokovic was great on placement. But Murray's at his athletic best, with a few returns sent wide. After a bit of back and forth it's Djokovic who holds serve for a 1-0 lead.
Serbian former tennis professional Dusan Vemic, who is a sometime-coach of Djokovic is on hand today - meanwhile, Jamie Delgado, an integral part of Andy Murray's squad, looks on as his charge hits about.
Djokovic comes into this match off a semi-final win over Fernando Verdasco of Spain. The Serb staved off a whopping five match points to take that win - a valiant effort but one that may not be the best sign of things to come...
The two of them met four times last year - exlcuding the Tour Finals, two of those times at Grand Slam finals. The pair faced off at the Australian Open and the French Open, both of which Djokovic won.
It's Andy Murray who won their last big encounter, though, which was at the ATP World Tour Finals in London last year. That win had sealed the year-end No. 1 title for Murray, who's been in the form of his life of late.
What a long, long rivalry. And until Murray found the epic form he's in right now, it was dominated by Djokovic. The former World No. 1 (that still sounds funny to the ear, doesn't it?) leads the pair's so far 35-match record 24-11.
