Golf:Sei Young Kim held her nerve to win the Blue Bay LPGA in China

South Korea's Sei Young Kim won the Blue Bay LPGA tournament in China by a single stroke after sinking an eight-foot birdie putt on the final hole.

Kim shared the lead with Taiwan's Candie Kung going into the final day, the pair level on one under with American duo Stacy Lewis and Kim Kaufman with just the final hole to play.

But Kung and Lewis missed their birdie putts, allowing Kim to drain hers to claim her third LPGA Tour victory of the season in wet and windy conditions.

"As soon as I saw this course, I realised it was my type of layout and really wanted to win, so I am very happy right now," Kim said.

The top four on the leaderboard were the only players to finish under par for the tournament as Sandra Gal, Xi Yu Lin and Alena Sharp ended tied-fifth on three-over-par, a stroke ahead of world No 1 Lydia Ko, who played the weekend four-under-par after a terrible start.

Lewis had earlier looked on course to claim her first tournament win of the year after five previous second-place finishes.
The world No 3 led by two shots after 12 holes but a bogey on the 13th allowed her rivals to reclaim ground on her.

Kim birdied the same hole and the next to leapfrog the American, while Kaufman picked up four shots in seven holes to move to one under for the tournament.

Joint overnight leader Kung also birdied the 14th to leave three competitors a shot back from the Korean.

Kaufman parred the last three holes to reach the clubhouse on one-under and when Kim hit a poor tee shot on the par-three 17th, her chances of glory appeared all but over.

Kung and Lewis hit superb tee shots to within five feet of the penultimate hole and when Kim three-putted to drop back into a tie for first, her playing partners both failed to sink the short putts that would have given them the outright advantage.

That left four players in a share of the lead as the final group headed to the par-five 18th, but when Kung and Lewis could only par the last, Kim held her nerve to drill in her putt and take the title.
