Highlights from the eleventh day of Australian Open 2013 at Melbourne Park...
Li Na. The 2011 Australian Open finalist had not beaten Maria Sharapova in their past two meetings, but chose this year's semi-finals to bring it in big style, routing Sharapova 6-2, 6-2 to reach her second Australian Open final. Sharapova looked completely bamboozled by the form and level of Li, and had little way to explain the defeat. Li meanwhile seems to be getting better and better.
The circumstances surrounding the completion of Victoria Azarenka's straight sets win over Sloane Stephens. Having served for the match at 5-3 in the second set, Azarenka was broken by Stephens, and then proceeded to take a double medical timeout, ostensibly for two separate injuries. Stephens, thrown by the 10-minute delay, then handed her serve, and the match, to Azarenka. It was more than a storm in a tea cup.
...to the final for Novak Djokovic. The defending champion was merciless in his 6-2, 6-2, 6-1 straight sets takedown of David Ferrer to reach his third straight Australian Open final.
'Doctor' Djokovic's medical ministrations to Goran Ivanisevic during the Legends' match which followed his win.
One better than 2012?
It could be for the Bryan brothers. The American twins made it into the men's doubles final with a hard-fought win over Italians Simone Bolelli and Fabio Fognini.
Watch out for...
Thanasi Kokkinakis. Not only does the young South Australian hav an extraodinary hair style, he has some game on the court, and knocked out No.2 seed Gianluigi Quinzi to reach the boys' singles last four.
