Ireland's Stephanie Meadow banked an impressive seventh-place finish at Kasumigaseki Country Club, with compatriot Leona Maguire back in a share of 23rd, as Nelly Korda of the United States survived a double bogey and a bogey in her final round to win gold in Saitama.

After her bogey on the 11th, Korda made a birdie on the 13th and all pars from there.

Her 17-under tournament total was just enough to fend off Mone Inami of Japan and Lydia Ko of New Zealand, who each fired six-under 65s to finish tied for second on 16 under.

Inami then needed just one play-off hole, a repeat of the 18th, to claim silver with a par, leaving Ko with the bronze medal.

Meadow opened her campaign with a round of 72 on Wednesday, but has excelled since, carding a 66, a 68 and concluding with a second 66 to finish on 12 under.

Maguire finished on five under after another round of 71.

Korda, 23, is a six-time winner on the LPGA Tour. She earned her first career major in June, capturing the Women's PGA Championship for her third victory of the year.

Inami put on a charge to contend down the stretch, making five birdies in a six-hole span on the back nine, although she lost a chance to catch Korda when she settled for a bogey on 18. Inami finished her fourth round with nine birdies and three bogeys.

Ko also ended her final round with nine birdies and three bogeys, although her run of birdies came on her front nine.

"It was a pretty up and down day," Maguire told RTÉ Sport. "I got off to a pretty rough start but really proud of how I hung in. I played some really great golf on the back nine so I'll take the positives out of the week. There were flashes of gold medal gold in there, just not enough ot it."

She added: "It's still a great experience and I'm proud to call myself and two-time Olympian."

Her team-mate Meadow was even more positive after her seventh place finish.

"Even despite Covid, it was one of the greatest experiences of my life," she told RTÉ Sport. " I think it's something I can build off for the next few weeks and the rest of the season. The interesting thing about this week is all you think about is top three - it should be the mentality I go into everyone tournament with."
