Djokovic still has a very slim chance of overhauling Nadal, but basically the year-end #1 and #2 spots are confirmed. So, now that the field for London is complete, the major thing remaining in rankings terms is the race for #3. There are five contenders: Murray, Ferrer, Del Potro, Berdych, and Federer. Federer will be eliminated from contention if he doesn't win Paris. Berdych needs to get to the final in Paris to have any chance. Realistically, then, it's a three-man race between Murray, Ferrer, and Del Potro. After wins for Ferrer and Del Potro today, the points total is: Murray - 5,790 Ferrer - 5,380 Del Potro - 5,055 If Murray were competing, he'd have a sizable advantage. As things stand, he needs the two rivals to slip up. Who will finish the year as #3?
