Michelle Wie has claimed the first major title of her career with a two-shot victory in the US Women's Open while Portrush golfer Stephanie Meadow finished third.
Meadow only turned professional just before the start of the championship.
The 22-year-old, who played collegiate golf in the US for Alabama, played exceptionally well to take sole possession of third place behind Wie and Stacey Lewis, finishing on one-over-par for the tournament after a closing 69.
But Wie was the big story of the day.
Many thought her destined for greatness when she finished in a tie for ninth on her major debut at the Kraft Nabisco Championship as a 13-year-old in 2003, but she largely failed to live up to her initial promise in the ensuing years.
But the Hawaiian has experienced something of a renaissance in recent months, and her triumph at Pinehurst in North Carolina is her biggest success to date.
Still just 24, she led the tournament from day two and came into Sunday with a three-shot advantage which she would not relinquish as a final round level-par 70 helped her finish on two under overall, two shots clear of compatriot Stacy Lewis, whose late charge proved too little, too late.
Lewis' closing 66 included eight birdies and four bogeys in an entertaining 18 holes and was the equal best round of the day, but the first-round leader's scores of 73 and 74 on Friday and Saturday undermined her title challenge.
Northern Ireland's Stephanie Meadow earned her best ever result at a major championship with a third-place finish on one over par for the tournament after a closing 69.
Amy Yang was a further shot back while South Korean compatriots Meena Lee and So Yeon Ryu finished in a tie for fifth.
Scotland's Catriona Matthew, the 2009 Women's British Open winner, edged her way into a tie for 10th after matching Lewis' round.
