MELBOURNE (Reuters) - Evergreen Venus Williams turned back the clock at the Australian Open on Monday to book her first grand slam quarter-final in five years and set up an intriguing matchup with Madison Keys, the teenager touted as the future of American tennis.
Williams' 6-3 2-6 6-1 upset of Agnieszka Radwanska under the Rod Laver Arena lights proved there was still life in her 34-year-old legs and ensured the United States would have a third woman in the last eight after younger sister Serena edged Spaniard Garbine Muguruza in the day session.
