American Pat Hurst birdied the final hole to card a four-under-par 68 and secure a one-stroke victory at the MasterCard Classic in Mexico.
Having started the day a shot off the top of the leaderboard, the 39-year-old made a solid start to the final round by carding three birdies without dropping a shot to reach the turn in 33.
A double bogey on the par-four 10th saw her momentarily drop down the leaderboard before she recovered with two successive birdies from the 11th.
A bogey on the short 14th again threatened to deny Hurst the victory but she birdied the 17th before picking up another shot on the last to snatch the win and the $195, 000 prize money.
World number one Lorena Ochoa, who had seen her strong start to the tournament undone by a 73 yesterday, carded six birdies but dropped three shots to finished tied second alongside Chinese Taipei's Yani Tseng (70).
Kim Song-hee of South Korea finished fourth after carding a three under 69 while American Cristie Kerr produced her best round of the tournament with a 67 to claim fifth.
