Master class from Sorenstam

World number one Annika Sorenstam looks set to become the first winner of the Dubai Masters after she increased her lead to seven shots with one round left at the Emirates Golf Club.

The Swede shot a third-round 68 to go 15 under par, with Karrie Webb, who had a 70, in second place on eight under and another Swede, Helen Alfredsson, third on seven under after a 68.
