Del Potro's back-to-back title run sees him surge into the top 25, at #23.
Will be interesting to see where he goes from here...definitely a solid shot at top 20 if he can remain fit...possibly a little higher. Montanes scored his first title, and moves up to #40. Verdasco finally got a grip and bagged his 2nd career title, moving him "comfortably" clear at #11 (considering that Tsonga is still out of action). Simon was solid in Indianapolis, and moves into the top 20 at #19.
A very interesting week in store, in Toronto. Djokovic will be hoping to rediscover last summer's magic if he is to remain in contention for a top 2 ranking...Federer must feel that he has to begin turning the tide on Nadal, right now...and Nadal, himself, can only be focused on surviving the first few rounds (as he will), enabling him to inch ever closer to a very likely stint as the #1 player in the official ranking system, within the next month or so.
As for the others, you'll notice that a fair gap has emerged behind the current top 10, and with a couple of those lagging behind forced out of contention, certainly for this week (e.g. Nalbandian, Tsonga), and several others being weaker on these courts / in these stronger draws (e.g. Robredo), there is a chance that the gap becomes wider still...
