Federer on course for title

Defending champion Roger Federer dropped his first set of the week but stayed on course to complete a hat-trick of Wimbledon titles when he overcame stubborn resistance from Nicolas Kiefer.

The world number one lost a tie-break and twice dropped his serve in the fourth set but they were only minor hiccups as he gained a 6-2 6-7 6-1 7-5 victory in two hours and 35 minutes to extend his winning run on grass to 32 matches.
