GAME DJOKOVIC 4-2. Perhaps a sign of preserving energy as Nadal effectively concedes that final point, turning down the chance of a chase.
Djokovic lets his anger show by hurling his racquet into the ground but it's back to deuce again.
A mammoth game could still go either way. Djokovic saves another break point and we are back to our fourth deuce.
GAME NADAL 5-2. Another huge game and Nadal is one game away from the set.
Djokovic breaks out into a smile after an unbelievable backhand at the net. 30-0.
SET NADAL 6-2. Djokovic goes long and Nadal is two sets to one in front.
Clouds are beginning to circle. The scheduled 5pm storm could be edging ever closer.
Nadal to serve, off we go in set four.
GAME NADAL 1-0. Perfect start for Rafa as the sun beams down again.
Not a lot to choose between these two in terms of winners. Nadal leading 37-36.
GAME DJOKOVIC 1-1. And Novak responds in kind, sealing the game with an ace.
@Sean - Rafa certainly looking the most likely now but yes, the more time Djokovic and Nadal are on court together the better!
An opening perhaps? 15-30 on the Nadal serve.
Nadal catching Djokovic out with a 76mph serve. The Serb can't quite believe it.
GAME NADAL 2-1. And that opening quickly vanishes as Nadal wins three points in a row to keep us on serve.
Five hours, 53 minutes. That was the length of the 2012 Australian Open final between these two. Doubt we will go that far but could certainly be heading towards two more hours today.
GAME DJOKOVIC 2-2. Still on serve as Nadal sends a shot long from the baseline.
GAME NADAL 3-2. Nadal's serve just catches the service line to go 40-0 up and Djokovic sends the next point long as he attempts to return a second serve.
@Solomon - Djokovic certainly not playing as he was in the first set but still well in the match if he holds here.
An energy sapping afternoon for sure. Both would've probably welcomed a rain delay but it has not yet materialised.
GAME NADAL 4-2. Is this the beginning of the end? Djokovic just not finding the positions on the court that he was earlier on and he sends one wide, Nadal now so close to a ninth French Open title.
Let us not forget that Djokovic broke straight back in set two.
Djokovic shakes his head. Seems to be resigning himself to his fate. But you never know. 15-15.
