DALY CITY, Calif. (AP) — Haru Nomura held on in strong wind to win the Swinging Skirts LPGA Classic on Sunday for her second LPGA Tour victory of the year.

The 23-year-old Japanese player closed with a 1-over 73 in wind gusting to 35 mph at Lake Merced to finish at 9-under 279 and beat South Africa's Lee-Anne Pace by four strokes.

Nomura won the Australian Women's Open in February, pulling away to beat top-ranked Lydia Ko by three strokes for her first LPGA Tour title.

Nomura had a rules scare Saturday. After her third-round 71, she met with rules officials to examine her play from an awkward stance on a slope in a bunker on the par-5 sixth hole. The officials decided no penalty was warranted for building a stance, leaving her with a par instead of a double bogey.

Pace finished with a 74.

Ko shot a 75 on her 19th birthday to tie for sixth at 1 under. She won the tournament the previous two years.
