LONDON (Reuters) - Light rain stopped play at Wimbledon on day five with world number one Rafa Nadal a set up against Gilles Muller on Court One as home hope Andy Murray waited to get on to Center Court for his clash with Croatian Ivan Ljubicic Friday.

Twice champion Nadal appeared below his usual energetic best and took a medical time out after falling toward the end of the first set moments before the wet weather arrived.

On Center Court fourth seed Victoria Azarenka and Daniela Hantuchova were locked at one set apiece when play was stopped for the roof to be set up, while on Court 18 last year's runner-up and sixth seed Tomas Berdych was on the brink of victory over American Alex Bogomolov Jr.
