South Korea's Choi Na-Yeon has not won a title since capturing last year's LPGA Northwest Arkansas Championship, but she hopes defending her crown starting Friday will revive her form. Choi, ranked 21st, shared third at the LPGA Swinging Skirts Classic in April for her best showing of the season but since then has struggled, missing the cut at the Women's PGA Championship and sharing 50th at the Meijer LPGA Classic the past two weeks. Choi, the 2012 US Women's Open champion, has won nine LPGA titles and six more on the Korean women's tour.
