Former Wimbledon winner Lleyton Hewitt of Australia set up a titanic quarter-final struggle against reigning champion Roger Federer when he knocked out Spain's Carlos Moya 6-4, 6-2, 4-6, 7-6 (7/3) in a thrilling Centre Court clash on Monday.

Hewitt, the seventh seed and 2002 champion, was too powerful from all parts of the court as fifth-seeded Moya, never the most comfortable on grass courts, struggled to make an impression before mounting a powerful, late rally which the Australian batted to subdue.
"I expected a tough match against Carlos. Grass is not his favourite surface but he won one match on grass in the Davis Cup final in Melbourne last year so he knows how to play," said Hewitt.
"I'll look forward to the challenge of facing Federer but I will have to raise the level of may game. He is capable of playing exceptional tennis."
Moya, playing in the fourth round here for the first time in seven career visits, showed a sure touch on serve and at the net in the early exchanges but Hewitt soon found his range.
The Australian went to set point and wrapped up the opener in 38 minutes when he forced the Spaniard to scurry from side to side before unleashing a fierce, low forehand which Moya could only return wide.
