I think keeping the #1 ranking will be difficult this year unless Nadal has another post Wimbledon slump, which I don't expect. Especially if Nadal does play one or two clay tournaments after Wimbledon. Nadal is getting closer, Federer can't afford to lose early in any of the TMS after Wimbledon
Roger has about 2,000 point lead over Nadal now but that is mainly from USOpen, Toronto, and Madrid. If Nadal has a slump or does worse at Wimby this year it will help.....but I don't think we can count on that happening at all. (He has virtually no hardcourt points to defend).
Nadal beat Roddick and Djokovic on a fast hardcourt at IW this year, so that's going to give him confidence that he can beat anyone on fast courts. Plus with Roger having lost some points, Nadal will be energized thinking that the year end #1 could be accessible this year.
If Roger were in his best condition he'd have a great chance with the rest of the year......but what about all this talk of his injury? If there is an injury then that makes it much tougher for Roger to defend his points.
Furthermore, I think that skipping Halle is going to hurt Roger at Wimbledon because he won't have match play practice under his belt. I know he was either injured or thought he could get injured.....so he felt he had to skip. I am just saying heads up everyone......Wimbledon is no forgone conclusion.
I hope we don't get extra pressure for Roger with reporter hype about him matching Borg's 5 Wimbledon's in a row streak. Roger has to stop letting media put him under pressure.
