Amy Olson mastered the gusts at Royal Troon to take a three-shot lead after round one of the Women's Open on Thursday.
The American made bogey at the par-four third but that was the only blot as she signed for a four-under-par 67.
Birdies at the fourth and sixth had Olson back on track, while a further three gains followed on the way home.
It was a fine score on a day where winds battered Troon, with Sophia Popov and Marina Alex (both one under) the only other players in the red.
Local favourite Catriona Matthew, a winner of this tournament 11 years ago, was one of 10 players who made level par.
World number four Nelly Korda battled to one over, but Danielle Kang was nine shots off the pace after the first round of 18 holes.
