It was going to be a grind because 18 had played so hard the entire week, but then it got cold and windy, according to Buhai, 33.
With the victory, Buhai joined Sally Little (1980 KPMG Women's PGA Championship, 1988 du Maurier Classic) as the second South African woman major winner.
She also became the eighth player to win a major championship, following Gary Player (1959) and Ernie Els (2002; both at Muirfield).
