Possible for Federer...
If I were you, I would also be concerned that he may finish at #3 this year since Murray is defending 180 points and is definitely playing his best tennis...
Possible that Federer may finish as #3, but that has about as much chance of happening now as Federer has of finishing #1. Murray will lose 400 pts for his runner up performance leaving his total at 7690 while Fed picks up 360 leaving him at 12165. I'm assuming Murray doesn't play Valencia or Basel, but even if he does Fed would have to play terrible, and Murray would have to win everything like Fed did last year.
