So, that was another victory for Novak Djokovic. He beats Roger Federer 7-6 (8-6) 5-7 7-6 (7-3) in three hours and two minutes to progress to the Paris Masters final.
No idea what happened in that tie-break but Novak Djokovic's winning streak extends to 22 and he's through to Sunday's Paris Masters final.
He's utterly delighted with that one. That was one heck of a tennis match.
So good to see Roger Federer back to form in that one though, he disappears straight off court.

Djokovic flies into a 40-0 lead but as Federer brings it back to 40-30, Djokovic can't help but flash a tiny smile at his opponent.
The 12th game is his those as a Federer return deflects out off the net.
Tie-break here we come.

Federer 6-7 (6-8) 7-5 5-5 Djokovic*
That one was simple for Djokovic. Four points done and dusted and we're tied once more.
What can Federer do here?
Post update
Federer* 6-7 (6-8) 7-5 5-4 Djokovic
Oooh, this is getting feisty. Djokovic lets his advantage slip and smashes his racquet on the court. He gets a warning from the umpire.
As Federer takes the advantage, the Serb drops his head. He then overhits a return and the game is Federer's. Djokovic isn't a happy chap.
Post update
Some remarkable hitting in this one and Djokovic takes a 30-15 lead with a cracker of a cross-court shot.
He then takes the next point for break point. He's had 10 so far but can he convert this one?
Nope. Federer ace. 40-30.
Post update
Federer 6-7 (6-8) 7-5 4-4 Djokovic*
Djokovic brilliantly holds on serve, finishing it off with an ace. He's only missed two first serves in this set, making 19 out of 21 so far.
Something tells me we're headed for a tie-break to decide this one.

If Karen Khachanov is watching this, which I'm sure he will be, he'll be delighted at how long Federer and Djokovic have been out on court ahead of tomorrow's final.
Two hours and 39 minutes, and counting...
Post update
Federer* 6-7 (6-8) 7-5 4-3 Djokovic
Somehow, Djokovic steers the ball around Federer beautifully to go 15-0 up on Federer's serve.
Federer is soon back in it though with an inch-perfect backhand, and goes on to take the lead as a challenge from Djokovic fails.
He goes 40-15 up as Djokovic returns straight into the net, much to his frustration, before Federer serves an ace for the game.

Federer 6-7 (6-8) 7-5 3-3 Djokovic*
An ace at 40-15 sees Djokovic take his service game. His serving in this third set has been sublime.
Post update
Federer 6-7 (6-8) 7-5 3-2 Djokovic*
Djokovic takes the game on serve but there's no doubting that Federer is getting stronger as this match goes on.
Can he get a break? He wins the next with a routine service game of his own.

Federer is giving it a rip, as the match clock moves
towards the two-and-a-half-hour mark.
After winning the Basel title last Sunday, he wasn’t even
sure whether he was going to play here.
