Kiwi golfer Lydia Ko has carded a one-over 71 during the third round of the US Women's Open at Pinehurst as other players tumbled down the leaderboard around her.

Pinehurst No 2 has proven tough to negotiate for many this week and Ko has been left to rue a six-over 76 during her first round, which basically took her out of contention for the tournament.

Her round of 71 today included three birdies and four bogeys and the 17-year-old is now in a share of 23rd place at eight-over.

Co-leaders Amy Yang and Michelle Wie, who are at two-under, are the only players under the card.


Ko could book a top-20 finish with a solid fourth round.

Meanwhile, Manawatu's Tim Wilkinson remains in contention at the Travelers Championship in Connecticut on the PGA Tour.

The left-hander fired a three-under 67 in his third round and is in a share of seventh place at nine-under for the tournament, four strokes back from leader Ryan Moore (-13).

Wilkinson has never won on the PGA Tour and a top-10 finish would be a nice boost for his season.
