World number one Roger Federer booked his place in the quarter-finals of the Pacific Life Open with a 7-6 7-6 victory over Croatia's Ivan Ljubicic in Indian Wells, California last night.
The Swiss whipped four winners in the second set tiebreak to break the resistance of Ljubicic who has now been beaten by Federer four times already this season.
Federer, the defending champion, will face Germany's Nicolas Kiefer for a place in the semi-finals after he dumped Argentine 10th seed David Nalbandian 6-1 6-3.
Before Federer's late show, former champion Andre Agassi had dazzled the crowd with some vintage form to blast past Argentina's Guillermo Coria 6-4 6-1 to set up a quarter-final showdown with world number two Lleyton Hewitt.
