PEBBLE BEACH, Calif. (AP) — Allisen Corpuz became the first American in 20 years to make the U.S. Women’s Open her first LPGA title, closing with a 3-under 69 on Sunday and handling her historic moment at Pebble Beach as if she had been there before.

Corpuz, a 25-year-old from Hawaii, pulled away with a big par putt and back-to-back birdies on the back nine to enjoy the most scenic walk in golf up the 18th fairway, the Pacific Ocean on her left and her place secured as the first U.S. Women’s Open champion at Pebble Beach.

She won by three shots over Charley Hull (66) and Jiyai Shin (68) and claimed the $2 million prize, the richest ever for an LPGA major champion.

Corpuz was so calm and cool on the grandest stage in women’s golf, regardless of the shot or the circumstances, until reality began to set in down the 18th. When she tapped in for par, she covered her smile with her hand and wiped tears away with her Aloha-print towel.

Corpuz, who finished at 9-under 279, was the only player to break par all four days.

Hilary Lunke in 2003 at Pumpkin Ridge was the last American to get her first win at the U.S. Women’s Open.

Corpuz never gave anyone much of a chance. Nasa Hataoka lost her one-shot lead on the opening hole when Corpuz hit her approach to 5 feet for birdie, and the 24-year-old from Japan dropped too many shots down the home stretch.

Hull, who started the final round seven shots behind, closed to within two shots early on the back nine and stayed in the game with a 30-foot birdie putt on the 16th. Shin made a birdie on the 18th to join Hull as a runner-up.
