Djokovic will be 1755 points ahead or 2155 points ahead of Federer in the race depending on tomorrow's result. Murray will still be 1750 (ish) points behind, or 1350 if he wins.
In the actual rankings Djokovic will move to within 500 points of Federer, or 100 if he wins.
The gaps between the three players are so big that I can't really see past the year ending Djokovic-Federer-Murray-Nadal.
Of course there will be a lot of points up for grabs in Paris and the WTF so who knows.
Oh, so he is playing Basel??
He's down to play it.
