South Korea's In Gee Chun held on to win the KPMG Women's PGA Championship by a single shot, while Stephanie Meadow finished in a tie for 10th.

Chun had held a three-stroke overnight lead at Congressional Country Club, having seen her previous advantage halved, coming into Sunday's finale.

But her three-over 75, coupled with a 73 and 70 respectively for joint runners-up Lexi Thompson and Min-Jee Lee, saw Chun win the tournament by the narrowest of margins on five under.

Antrim's Meadow carded a final round 74 to finish on level par overall, five shots off the winning mark.

She birdied holes nine and 12 but four bogeys saw her narrowly miss out on breaking into the top five.

Leona Maguire, meanwhile, endured a difficult tournament and ended up on nine over after a 74.

The Cavan native, who won on the LPGA Tour in February, did not manage a birdie in the final round with bogeys on six and 13.


FINAL LEADERBOARD


In the battle for victory, Chun appeared to have surrendered a third major as she dropped four shots on the front nine.

That allowed Thompson to hit the front and victory seemed hers for the taking but the American, who squandered a winning position at last year's US Women's Open, once again unravelled by bogeying four of the last seven holes.

Chun consequently ended up winning by one stroke on five under, despite signing for a three-over-par 75.

Thompson shot 73 and finished in a tie for second on four under with Minjee Lee, who recorded a two-under-par 70.

Thompson looked to have taken firm control when she birdied the 11th to lead by two with seven to play but her problems began with a five at the par-four 12th.

Another bogey followed at the 14th and, although she clawed it back with a birdie three on the 15th, worse was to follow.
She took a six at the par-five 16th after a poor chip and an overhit putt and then dropped another shot on the 17th.

Chun, meanwhile, regained her composure and went back to five under with a birdie at the 16th. That proved enough to keep her one ahead of Thompson and Lee, who had finished strongly with two birdies in her final three holes.

"It just means a lot because I didn't have any wins for three-and-a-half years," said Chun at the presentation ceremony.

"My sponsors always believed in me, my family and my coach, my caddy and my fans in Korea, they never gave up on me."
