Chun clinches US Women’s Open

South Korea’s Amy Yang surrendered a three-shot lead as compatriot In Gee Chun claimed victory at the US Women’s Open at the Lancaster Country Club on Sunday.

Chun, who registered seven birdies and three bogeys in her final-round 66, became the first player to win the tournament on debut since Birdie Kim did so 20 years ago.

The 20-year-old profited from a mid-round wobble from Yang who dropped four shots from the ninth to the 15th, only for the overnight leader to launch a late recovery by going eagle-birdie at the 16th and 17th to move back within one stroke of the lead.

Three straight birdies from the 15th to the 17th had kept Chun in front, and with both players bogeying the last, it would be Chun who came out on top by a single stroke after finishing on eight-under for the tournament.

World number one Inbee Park finished in a tie for third with Stacy Lewis after carding a tournament-best 67 on Sunday.

Park made six birdies and three bogeys during her final-round 67, while Lewis finished with a level-par 70.

Brooke Henderson, Pernilla Lindberg, So Yeon Ryu, Jane Park, Morgan Pressel and Shiho Oyama finished on three-under, five shots off the pace and in a tie for fifth.

World number two Lydia Ko ended her tournament on a high after registering a round of 68 to finish in a tie for 12th on one-under.

Defending champion Michelle Wie found herself alone in 11th place on the leaderboard after a final-round 70, which saw her make two birdies, four bogeys and an eagle on the 16th.
