Okay, we're into the QF stages, so let's have a quick round-up...
Nadal, Djokovic and Federer are still intact, so obviously no changes inside the top 3.
Murray's R4 thrashing of Wawrinka, combined with Davydenko's demise to Muller, allows Great Britain's finest to now move up to #4.
Roddick's progress to the QF has earned him enough points to leap clear of Blake, and he could also overtake Ferrer, into #6, if he can find a way past Djokovic, next.
Del Potro's expected progress has now pushed him into the top 10, and a win over Murray would elevate him into the "Shanghai 8" - provisionally, of course.
Can't say too many expected Fish to be in the QF, and this impressive run pushes him up to #16.
One other guy I have yet to mention...Gilles Muller! He started this tournament with just 5pts, and a ranking in the #180s...a QF berth moves his tally up to 58pts, and a new ranking of #86. Very impressive progress by him, and I'm sure it must be a few years since we last had a qualifier in the QF of a GS.
The only guy coming to my mind at this present time is Voltchkov (former Wimbledon SF'ist), but maybe I'm wrong.
