World number one Lorena Ochoa took command of the Women's British Open as wild winds sent scores soaring in the third round at St Andrews.
Ochoa carded a level-par round of 73 to lead on six under, six shots ahead of Sweden's Linda Wessberg.
Former world number one Annika Sorenstam could only manage a round of 77 and was in a four-way tie for third place on one over par.
Scot Catriona Matthew, who started the day in second place, carded an 80.
"It was just so tough," said Matthew who is now eight shots back on two over par.
"I made a bad start and never really got going. But I just hope it is better tomorrow."
Ochoa said she was determined to continue in the same vein on Sunday and hoped to stretch her advantage.
"I have a six-shot lead, so tomorrow I'm not going to pay attention to other players and just play my own game and try to be aggressive and make some birdies," Ochoa said.
I would think these were the toughest conditions in a major, maybe ever
"I think once you try to start doing something different you get in trouble. I just want to play my game and hopefully, I can win maybe by more."
Sorenstam bogeyed four holes on the outward nine, but said she made a good recovery.
"I was just trying to be smart, hit fairways and greens and go from there," Sorenstam said.
"I believe I shot level-par the last 10 or 11 holes. I'll take that any time in a championship like this. I just didn't get off to a good start.
"But I would think these were the toughest conditions in a major, maybe ever. It's tough to drive, tough to hit irons, tough to putt."
Derbyshire's Melissa Reid was the best of the amateurs after shooting a 76 for five over par and was three ahead of her English colleague, Rachel Bell, in the race for the amateur salver.
