Davies had 66-to-1 odds against her in her home country when the week began last year, and declared herself a head case after her round on Friday. But by Saturday night, she had a five-shot lead on Brandie Burton and Maria Hjorth. She breezed around the course Sunday to win by three shots and finish at 9-under 279.
Davies actually led by six shots during the final round before she eased up toward the end. She made just four bogeys and one double bogey during the tournament.
This year she enters the event 37 places higher in the money list, and will be defending against past Rochester champions Rosie Jones, Meg Mallon, Deb Richard, Karrie Webb and the farewell-touring Nancy Lopez.
