Mone Inami won Japan's first Olympic golf medal when she emerged victorious from a playoff for silver against New Zealand's Lydia Ko on Saturday, with both players finishing one shot behind gold medalist Nelly Korda of the United States.

Inami beat Ko in a sudden-death playoff after both players shot 6-under 65s and were tied for second on 16-under after 72 holes at Kasumigaseki Country Club in Saitama Prefecture.

Korda, winner of the Women's PGA Championship in June, finished with a 69 for a 17-under total, helping the United States secure a gold medal sweep of golf following Xander Schauffele's triumph last week.
