It’s been another busy day down under with Australian Open quarterfinals underway. The hot temps which climbed over the century mark were too much for defending champion Novak Djokovic, who succumbed after dropping the second and third set along with his serve before stunningly quitting allowing American Andy Roddick to advance to the semis where a highly anticipated match awaits with Roger Federer making short work of talented Argentine Juan Martin Del Potro with maybe two bagels when it’s all done.

So, it will be Federer-Roddick in a throwback match-up with the slam history one sided. Can a lighter and more focused Andy finally get Roger in a momentous occasion with the final on the line? We’ll see.

As for Djokovic who played a brilliant first set tiebreaker winning 7-1 slugging forehand winners, it was a bitter disappointment to run out of gas. A certain eye opener for his closest rivals Federer, top ranked Rafa Nadal, Andy Murray and Roddick back in the mix.

Jelena Dokic’s amazing run finally ended but not without drama losing in three closely fought sets to No.3 Russian Dinara Safina by scores of 6-4, 4-6, 6-4. The popular adopted Australian didn’t fall easily breaking Safina for four all and even fighting off break points setting up game point. But she was unable to put it away and also failed on a couple of more opportunities to even it at five.

Safina next faces Russian Vera Zvonareva who easily straight setted Marion Bartoli with a spot in the final up for grabs.

Much more on today’s results later.
