Tennis: Tsitsipas won by playing Federer-style - Luddy
Roger Federer has lost his chance at a third consecutive Australian Open title, losing out to 20-year-old Greek Stefanos Tsitsipas in Melbourne on Sunday night. Tsitsipas says he's the happiest man on earth, and here's what he had to say about beating his idol. New Zealand's top ranked doubles player Michael Venus and his South African partner Raven Klaasen have stormed into the quarter finals. The 6th seeds have thumped the Brazilian-Danish duo of Marcelo Demoliner and Frederik Nielsen 6-3 6-1 in just over one hour. Our correspondent in Melbourne is David Luddy.
