MILTON KEYNES, England — Hinako Shibuno of Japan won the Women's British Open on Sunday in her major championship debut, holing an 18-foot birdie putt on the final hole for a one-stroke victory over Lizette Salas.

The 20-year-old Shibuno, a rookie on the Japan LPGA Tour who was making her LPGA Tour debut, birdied five of the final nine holes for a 4-under 68 and an 18-under 270 total at Woburn Golf Club.

Largely unknown before the championship, Shibuno — nicknamed "Smiling Cinderella" — started the round with a two-stroke lead, but lost it with a double bogey on the par-4 third. She birdied Nos. 5 and 7 before a bogey on the eighth.

She birdied Nos. 10-12, all par 4s, added another on the par-5 15th and closed with the winner on the par-4 18th.

Salas finished with a 65.

Jin Young Ko, who was seeking her third major title of the year after winning the Evian Championship last week in France, was two shots back after a bogey-free 66. Morgan Pressel (67) was fourth at 15 under.
