Agnieszka Radwanska has overcome a tough first set to defeat Bojana Bobusic in the first round of the Australian Open.
The Serbian-born Australian broke in the very first game of the match before serving for the opening set at 5-4.
However, the world number four won three games in a row to snatch it from under her nose.
It was a clean sweep in the third set as Radwanska overpowered her opponent with a 91% success rate on points coming from her first serve.
The 23-year-old will now play the winner of Irina-Camelia Begu and Arantxa Rus.
