Chinese No. 27 seed Qiang Wang has produced the biggest shock result of the Australian Open so far after knocking out Serena Williams with a 6-4, 6-7 (2-7), 7-5 victory on Rod Laver Arena. Wang capitalised on a triple break point at the first time of asking when 5-4 up before serving out the opening set. And she was able to neutralise Serena's power by moving her around the court, forcing Williams into a gruelling contest. Wang played the match of her career and the 28-year-old broke the Williams serve again in the fifth game of set two to go 3-2 up. But with Wang given the opportunity to serve out the match, Williams fashioned out two break points and needed only one in a superb 24-shot rally to break the Wang serve for the first time. Williams scrambled to a 5-2 lead in the tie-break before securing the set. In the decisive third set, Wang showed her true grit to stay in the tie with the momentum swinging Williams' way. Wang was up an advantage in the eighth game but Williams responded to make it 4-4. And with Wang 6-5 up in the final set, she won match point at the third opportunity on Williams' serve to seal a historic victory. Williams ended the match with 56 unforced errors to 43 winners, with her early exit meaning the wait for Grand Slam No 24 goes on.
