Brewerton leads by five ahead of final round in South Africa

Wales' Becky Brewerton extended her lead to five shots after round three of the Investec South African Women's Open despite shooting a two-over-par 74.

Only one player was under par in breezy conditions on Friday - Paz Marfa Sans firing a two-under 70 - allowing Brewerton to assume further control having led by four strokes after round two.

"I think it was a day where everyone knew you were going to make mistakes and be in difficult positions. You just had to try and minimise it."

Brewerton's last victory on the Ladies European Tour came at the Open De Espana Femenino back in 2009.

She added: "I don't think I'll have any problems going to sleep. I'm exhausted.

"Tomorrow will just be another day of trying to keep the ball low. I fully expect the breeze to be just as strong, if not stronger, so I'll be mentally prepared."

Johnson is still in the mix after a mixed day - the 36-year-old was as high as four under after five holes but then bogeyed the 10th hole and double-bogeyed the 13th and 15th in a three-over-par round.

Johnson said: "I enjoy playing the wind, but maybe
