Australian Open: Serena, Venus Williams on course for showdown

When the 34-year-old beat sixth-seed Agnieszka Radwanska 6-3 2-6 6-1, she ensured a quarterfinal berth at a grand slam for the first time in five years. Further it was her first top-10 win at a major since downing Italy’s Francesca Schiavone at the 2010 U.S. Open.
