South Korea's Chun In-gee has managed to hold on and win the Women's PGA Championship by one stroke, despite finishing her week with back-to-back 75s on Saturday and Sunday.

Chun finished on five under to win her third major championship, but she entered the weekend with a massive lead after rounds of 64 and 69 had her at 11 under, six strokes clear of the chasing pack.

Only nine players finished the tournament under par, illustrating the difficulty of the course and conditions at Congressional Country Club.

In a tie for second was Australia's Minjee Lee – fresh off her U.S. Open win – along with American Lexi Thompson at four under.

Thompson entered the day at five under and shot a 73 to drop one stroke, while Lee came in at two under – and bogeyed her first two holes of the day – but went four under across her final 16 holes for a Sunday 70.

Thailand's Atthaya Thitikul claimed outright fourth place at three under, two strokes clear of the five-woman pack tied for fifth at one under.

That group had three South Koreans – Kim Hyo-joo, Kim Sei-young and Choi Hye-jin – to give the country four of the top nine.

In a notable performance, Australian Stephanie Kyriacou posted four consecutive even-par 72s and finished tied for 10th.
