A topsy turvy match between Sock and Zverev in a topsy turvy year means that Wawrinka will start next year ranked 9. This leads to a last 16 if seedings play out and no injuries at the AU's Open with Wawrinka, Djokovic, Murray and Del Potro all there to meet top 8 players. I wonder what the odds would have been for a Sock v Djokovic last 16 match with Djokovic being seeded to lose a year ago.
If Federer goes on to win the tournament he would only be 140 points behind Nadal in the rankings. Now, fair enough, he has a lot of early year points to defend but it could be that he sneaks to Number 1 early next year. If Nadal's injury isn't healed for the Aus Open, Federer getting to final would take him to number 1.
