After winning five majors from 2008 to 2011, the 23-year-old from Taiwan is slumping for the first time in her career. Though she is still the top-ranked woman by a wide margin, her last win came in March. At the NW Arkansas Championship last week, Tseng missed the cut. She has never won the U.S. Open.
In 10 major starts, the 17-year-old has never finished inside the top-10. There's little question she has the game, however. She ranks in the top five in driving distance and greens in regulation. She still has a year to break Morgan Pressel's record as the youngest woman to win a major (18 years, 10 months).
The 27-year-old, ranked third in the world, is widely recognized as the best player never to win a major. She has 15 wins in Japan and nine on the LPGA Tour, including last week in Arkansas. Miyazato has finished in the top-10 in majors 10 times and leads the tour in putting average, scoring average and rounds under par.
The 25-year-old from California has nine LPGA wins and one major championship, capturing the 2010 U.S. Women's Open at Oakmont. The "Pink Panther" enters in solid form after top-15 finishes in three of her last four events. She ranks 12th in the world and third on tour in greens in regulation.
In 2008, she became the first player from mainland China to join the tour. Last month she became the first from her nation to win a major when she captured the LPGA Championship. It was her first tour win but hardly a fluke. She has finished in the top-five four times this year and ranks fourth in the world.
