Wimbledon:Roger Federer shattered father-to-be Lleyton Hewitt's Wimbledon hopes with a 7-6 (9/7), 6-2, 6-4 victory which took the five-time champion into the quarterfinals.
Federer, bidding to become the first man to win six successive titles, racked up his 63rd successive grasscourt victory and will take to either Spain's Fernando Verdasco or Croatia's Mario Ancic for a semi-final place.
His victory also assured the top seed that he will retain his world number one spot once the championships are over.
Hewitt, the last man to win Wimbledon in 2002 before Federer went on his unbroken All England Club run, went into the fourth round match nursing a long-standing hip injury and regularly winced wit pain on Centre Court.
The agony was eased by his announcement earlier in the day that he and his 24-year-old wife Bec, a former soap star, were expecting their second child in January.
However, Federer ruined the celebrations by claiming his 14th win in 22 meetings with the gutsy 27-year-old Australian.
"I served well which was important," said Federer who saved all eight break points he faced. "But I could see Lleyton was struggling. The tiebreaker was key as that put me on the way and I saved break points when I had to."
Hewitt, whose last win over the top seed came in 2003, matched Federer blow for blow in the first set which the Swiss star eventually grabbed on a third set point in the tiebreak on an ace.
Federer eased through the second set with breaks in the first and third games and was quickly 3-1 ahead in the third after fending off break points for the fourth service game in a row. That was eight break points in eight saved and Hewitt's fate was quickly confirmed in the 10th game.
