Jennifer Kupcho overcame a back-nine stumble to win the Chevron Championship, securing her maiden major victory and first on the LPGA Tour.
The 24-year-old American, who won the Augusta National Women's Amateur three years ago, carded a two-over 74 in the final round at Mission Hills Country Club in California to finish on 14-under 274, two clear of Jessica Korda.
Kupcho started the day on 16 under, with a six-shot lead after a 64 on Saturday, and extended her advantage to seven following a strong start which saw her hole some lengthy putts as she birdied the second, fourth and fifth either side of a bogey at the third.
Defending champion Patty Tavatanakit of Thailand was Kupcho's nearest pursuer overnight and played alongside her in the final group, but she endured a frustrating day as she missed numerous chances after sandwiching a bogey at the fourth with birdies at the second and fifth.
That left Korda to mount the strongest challenge after she was buoyed by an eagle at the third where she holed out from just off the fairway.
