Moriya Jutanugarn held a two-shot lead on the 15th hole during the final round of the Pure Silk Championship on Sunday at 12 under.
She then found herself down two shots walking to the 16th tee.
The 2013 LPGA Rookie of the Year made a double bogey on the par-5 15th, while Wei-Ling Hsu — who entered tied for the lead at 10 under and was even par on the day at the time — made eagle to flip the leaderboard and increased her lead with a birdie on No. 16.
Hsu earned her first LPGA win at 13 under, playing the River Course at Kingsmill Resort in Williamsburg, Virginia, 3 under on Sunday. The victory also grants the 26-year-old access to the U.S. Women’s Open, held June 3–6 at Olympic Club in San Francisco.
The New Taipei City, Taiwan, resident will take home $195,000, bringing her season-total to $323,801 and career to $2,083,580.
