Cincy CC Day 4, Reiterated

It's that time of day again - the original Crisis Center post has gone into 1000+ comments territory. Yet again, it has been an eventful day, with Carlos Moya seeing off both Nikolay Davydenko and Igor Andreev in the same day, Andy Murray progressing convincingly over Dmitry Tursunov, and Ivo Karlovic scoring his first career win over current world number one, Roger Federer, in a third-set tiebreak. The likely next world number one, Rafael Nadal, has yet to play today (he meets Tommy Haas at 7 p.m.). By my calculations, only two matches now stand between Nadal and the certainty of gaining the number one ranking by August 18th - and even if Nadal loses tonight, Federer needs to reign supreme at the Olympics to keep the top spot, and to do it, he would need Nadal to flame out early in Beijing.
After the rest of the tennis is over, it's OK to go off-topic here - until then, it would be much appreciated if the subject of the conversation could remain on the day's play.
