Federer had to go play Rotterdam to sneak in a cheap 500 and 21 tournaments vs 19 for Novak. Despite this Federer has less than a 100 points lead right now.
Don't care who is number 1 at the end of the year, I just want Novak to win the US open.
Djokovic also tried to win Dubia but he couldn't.
and since we are talking about the points and tourneys, Djoko played two masters more so far.
besides, the season hasn't finished yet, till then you we can't talk about the number of tourneys played.
