Yes, but the rules are bent in Wimbledon. If one slam can do it then another can too.
Personally, I'm against that Wimby thing, but they do it always (or at least for quite some time now), which is why everybody is in the same position and I guess it's kind of 'fair'.
But changing the rules to suit the tournaments rating/money needs as soon as the circumstances are problematic, would be disgraceful beyond belief. Taking Andy Murray to #5 (if they choose to go by clay results) is basically illegal, let alone taking David Ferrer out of top 4. That's just taking points away.
personally, I wouldn't mind the scenario. it would be awesome if guys like Jo or Grigor could come all the way through to the finals
Grigor? Hope you are joking, mate. We will see a Llodra-Stepanek final in RG before we see that.
