Teenager Lydia Ko took her tally of LPGA titles to 13 with a three-shot victory at the Arkansas Championship.
The 19-year-old New Zealander claimed her third victory of the season despite ending her final round on Sunday with a bogey six on the par-five 18th hole.
"It wasn't the greatest ending to finish up with a six," Ko told the Golf Channel. "It covers up how well I played earlier on."
The world number one ended with a tournament-record 17 under par.
Her total of 196 in the 54-hole event at Pinnacle Country Club left her three shots clear of Taiwan's Candie Kung and American Morgan Pressel.
Ko's victory at the ANA Inspiration tournament in April made her the youngest two-time major winner in LPGA history.
