The Danish tennis player Caroline Wozniacki has regained her status as the world number one after beating Israeli Shahar Peer in straight sets to reach the semi-finals of the Dubai championships.
The victory ensured that Wozniacki, who had surrendered her number one ranking to Belgian Kim Clijsters a week ago, will return to the top spot when the new world rankings are issued on Monday.
Australian Open champion Clijsters, who took the top ranking on her way to the Paris Open final last week, is not playing in Dubai.
