Greats to launch new shortened format in Sydney

TWENTY20 has revolutionised cricket and now a shortened version of tennis is to be unveiled by Lleyton Hewitt and Roger Federer in Sydney next year.

The two greats will take part in a best-of-five-sets exhibition match at the Sydney Entertainment Centre that will have first-to-four sets, no advantage scoring, no service lets and tiebreakers at three games all.

Initiated by Tennis Australia, the format will be a world first.

The pair will meet a day after the final of the Brisbane International - a tournament they made the final of earlier this year - on January 12, a week before the start of the Australian Open.

"Playing Roger in this new format will be an exciting challenge for both of us and a lot of fun," Hewitt said.

"It's a fantastic innovation for tennis and one that I hope will take off."
