Night Owl Federer Swoops Past Berdych

Perhaps Roger Federer should stay up late more often. The defending champion revealed he had staved off sleep to see some of Lleyton Hewitt's marathon win over Marcos Baghdatis - a match that did not finish until 4.33am on Sunday morning - but the defending champion showed few signs of tiredness as he beat No13 seed Thomas Berdych in straight sets 6-4, 7-6 (9-7), 6-3.

Federer did lag slightly in the second set when Berdych held two set points. "He was playing better [than me] in the second set, honestly," said Federer. "He got an early lead, then played well in the breaker. In the end, maybe he made a wrong shot selection. It's unfortunate for him, but jeez, it's good for me to win in straight sets."

Federer had looked imperious in the first set, dropping just four points on his own serve, and after his scare in the second was again dominant in the third as he broke Berdych to love in the sixth game before serving out the match in complete control.

The Swiss will play James Blake in the last eight after the American beat 19-year-old Marian Cilic 6-3, 6-4, 6-4. It was a particularly satisfying win for Blake, who had previously failed to reach a grand slam quarter-final outside the US Open.

Men's results, fourth round:

(1) Roger Federer (Swi) bt (13) Tomas Berdych (Cze) 6-4, 7-6 (9-7), 6-3 (12) James Blake (USA) bt Marin Cilic (Cro) 6-3, 6-4, 6-4
