South Korea’s Na Yeon Choi posted a seven-under-par 64 on Thursday to establish a one-shot lead after the first round of the Jamie Farr Owens Corning Classic in Sylvania, Ohio.

Two weeks after Greg Norman threatened to become the oldest major winner ever American Juli Inkster today set up the chance to do the same in the women’s game.

Britain’s Laura Davies and Momoko Ueda are tied for the lead on seven under par heading into Sunday’s final round of the Mizuno Classic.
