The WTA website does claim that this is Niculescu's CH for singles. But, it's not. That's her doubles CH. Her singles CH is 28, week of 27th Feb, 2012. That is correctly displayed on the WTA website, but only if you drill into the'Rankings History' section.
I only mention it as a caution that all players on the WTA site whose doubles CH is better than their single CH may have wrong information in the summary section. ITF have the correct data however.
In the meantime I think the main draw is now scheduled for overnight at 3.00 GMT. It has been moved back from early on Thursday morning British time.
The Guardian's website says it is scheduled for afternoon Melbourne time - if it was 3 am I might stay up and wait for the info to appear, but if it is 6-9 am UK time, that means go to bed now for me and wake up to hear the news. Really hoping that Fran and Katie B get winnable matches, and Heather and Jo fare well too, but for Katie B and Fran, win a match or two and they will shoot up the rankings, so the draw is much more crucial to them than Heather or Jo, I think. Can't wait for it to start - it is my second favourite tournament after Wimbledon, as I finish work each night at midnight and then get to see it all live for a few hours, for everyone else I am sure that Aussie time is a pain in the proverbial.
