SHOAL CREEK, Ala. (Reuters) - Thailand's Ariya Jutanugarn and South Korean Kim Hyo-joo headed to a two-hole aggregate playoff to decide the U.S. Women's Open at Shoal Creek on Sunday.

Ariya suffered an epic collapse on the back nine, blowing a seven-stroke lead after a triple-bogey at the par-four 10th.

She missed a 10-foot putt that would have won it at the last, shooting one-over-par 73, while Kim carded 67 to tie it at 11-under-par 277.
