The 25-year-old scored a level-par 71 to win on 14 under, one stroke ahead of Australian Hannah Green at Jersey City’s Liberty National Golf Course.
Korda started the final day with a two-shot lead, but three bogeys and one birdie on the front nine brought him level with Green at the halfway point.
After matching each other down the stretch, it was the Australian who faltered first, missing a par putt on the 18th that would have forced a playoff.
The victory means American Korda bounced back at the first chance after her winning streak of five came to a stop at last week’s Cognizant Founders.
