Lleyton Hewitt, Roger Federer to launch fast tennis in Sydney A year after Melbourne spent "A Night with Roger Federer and Friends" in the name of charity, Sydney will on January 12 host "One Night With Roger Federer and Lleyton Hewitt" to launch a new Australian-devised fast format of tennis. Federer will stop en route from Brisbane to Melbourne, where the 17-time major winner will conclude his Australian Open preparation, to contest five sets of a shortened version of the game piloted at clubs across Australia. There are four rule variations from traditional tennis: no advantage scoring; no lets; a tiebreak at three games all; and sets won by the first player to four games. It will be Federer's first trip to Sydney since the 2011 Davis Cup tie; the Swiss great's five-title 2014 season ended with a career-first Davis Cup triumph against France last weekend. Tennis Australia chief executive Craig Tiley hailed the new truncated match format as a "game-changer" with an appeal to time-poor players that will "revolutionise" tennis, particularly at club and social levels. Federer and Hewitt - both 33-year-old fathers and former world No.1s - have forged a strong friendship since the first of their 27 career meetings in 1999, with Federer ahead 18-9 but the South Australian winning their most recent meeting, in the final of this year's Brisbane International. Both will travel to Asia this week for the inaugural International Premier Tennis League exhibition series, also to be played under modified rules.
