Serena holds firm as Clijsters, Venus fall


Defending champion Serena Williams (pictured right) moved into the semi-finals at Wimbledon with a 7-5, 6-3 win over Chinese ninth seed Li Na.
Williams claimed a last four place at the All England Club for the seventh time in her career.
Li was completely outplayed by the American top seed as her game unravelled on Centre Court and she never looked likely to emulate her achievement of reaching the semifinals of the Australian Open.
