Federer wins first match at 02

Roger Federer wasted little time in opening the defense of his Barclays ATP World Tour Final crown with a 6-3 6-1 victory over Janko Tipsarevic at London's 02 Arena.

Federer is looking for a hat-trick of titles in Greenwich and a seventh at the tournament overall having set a new record with his final triumph over Jo-Wilfried Tsonga 12 months ago.

He withdrew from defending his Paris Masters crown last week to prepare for London and he certainly looked sharp as he brushed aside the challenge of Tipsarevic.
