Federer trounces Hewitt to march into quarter-finals

MELBOURNE (Reuters) - Roger Federer extended his winning streak against Lleyton Hewitt to 15 matches Monday, easing into the quarter-finals of the Australian Open for the seventh year in a row.

The world number one was at his ruthless best against his old rival, racing to a comprehensive 6-2 6-3 6-4 triumph in less than two hours in front of a packed Rod Laver Arena.

Hewitt, the last local player left in the draw, won eight of his first 10 matches with Federer but has not beaten the Swiss since 2003, and the gulf between the current and former world number ones has never looked wider.

Federer can expect a tougher match in the next round against Nikolay Davydenko after the Russian advanced to the last eight with a fighting 6-2 7-5 4-6 6-7 6-3 victory over Spain's Fernando Verdasco.
