''A win is a win,'' Inkster said. ''This is a good golf course and this is the best I've ever putted on Bermuda greens.''
Hurst also shot a 68.
''If there's anybody you need to beat out here, it's her because she works so hard at it,'' Hurst said about close friend Inkster. ''She practices hard and works hard on her game and on her body.''
