World number one Annika Sorenstam stretched her lead to five shots at the halfway stage of the Dubai Ladies Masters thanks to a second-round 68.

The Swede birdied five of her opening 15 holes before dropping her first shot of the tournament at the eighth - her 17th hole.

Australia's Karrie Webb, ranked third in the world, also shot 68 to move into second place on six under.

England's Trish Johnson is in a three-way tie for third on five under.

Johnson had the best round of the day - a 67 - with a strong back nine of 32 which included three birdies in a row from the turn.

But she is still chasing Sorenstam, who marked the end of her round by going on a camel-riding trip in the desert.

"I'm really pleased to be 11 under at halfway, I played really well, especially getting to the turn in four under," she said.

"On the back nine, I just couldn't really get anything going. But just one bogey in 36 holes is pretty satisfying."
