(BBC) – China’s Ruoning Yin held her nerve to sink a 72nd-hole birdie and win the Women’s PGA Championship.

The 20-year-old was level with Japan’s Yuka Saso on seven under heading to the par-five 18th on Sunday.

Yin calmly rolled in a fourth birdie of her final round to seal a first major title in New Jersey.

She shot 67 to finish eighth under (276) overall, with Saso a shot back in second after she carded a final-round 66.

“I knew I had to make birdie on that hole to win a championship, and I am glad I did it,” said Yin.

“I only missed six greens in four days, I think, so my course tracking was pretty good.”

Ireland’s Leona Maguire started the day with a one-shot lead, but dropped down the leaderboard to finish in a share of 11th, four shots behind Yin.

A birdie on the 17th gave Northern Ireland’s Stephanie Meadow brief hope; she needed an eagle on the last to force a play-off, but could only manage a par, and finished in a tie for third on six under.

Former amateur star Rose Zhang won the Mizuho Americas Open on her professional debut earlier this month, and was a shot off the lead after six birdies in her first 14 holes on Sunday.

However, the 20-year-old bogeyed the 16th, and finished in a tie for eighth on five under.
