Roger Federer shows no charity to friend Jo-Wilfried Tsonga COMBINING overt aggression with the precision of a surgeon, Roger Federer stormed into the quarter-finals of the Australian Open last night by trouncing Jo-Wilfried Tsonga 6-3 7-5 6-4 in under two hours. This was a master class reminiscent of his time as the solitary king of the sport. A fortnight ago the good friends played an exhibition on the same court in the name of charity. Last night, too, was an exhibition, but Tsonga found nothing charitable about Federer's level of play.
