The com. just said that should Any get to the final he may move to # 2 in the rankings.
I hope so.
If he wins IW he will become #2, if he reaches the final and Federer goes out before the SFs (say, to Nadal in the QFs) then he would become #2 that way as well.
It's a tough ask though. I think bare minimum, he needs to make the semi-finals and hope Federer doesn't win it. That would close the gap by at least 750 points.
