Leona Maguire earned a top-30 finish in the Chevron Championship after a final round 73 saw her finish at even par overall as the first major of the year went to the wire in Texas.
American Lilia Vu beat compatriot Angel Yin in a play-off to collect her maiden major title, taming a challenging and unfamiliar course at the Club at Carlton Woods near Houston.
Vu started the day four shots back but marched up the leaderboard with five birdies - including two on 17 and 18 - and one bogey, carding a four-under par 68 for a winning total of 10-under 278.
She waited nervously on the sidelines as previous leader Yin (72) let the affair slip to a tiebreak with a pair of late bogeys.
Yin did not put up much of a fight in the playoff as her second shot hit the water and Vu, who collected her first title on the tour at the Honda LPGA Thailand in February, held her nerve to drain a long birdie putt for the win.
"I can't even put into words what I was feeling - I was nervous, I was scared, I was cold," Vu said in a televised interview
"I just wanted to hit the putt."
The 25-year-old, who had considered quitting the sport only a few years ago, was overcome with emotion after securing the win and said it was validation for the struggles she faced in her career.
Maguire appeared to fall out of contention with an opening 76, firing a creditable 69 to creep inside the cut on Friday. A round of 70 on Saturday took her to one-under par for the tournament, leaving her nine adrift of the leaders.
In her final round, Maguire posted 35 on her outward nine after a dropped stroke on the 4th was followed by birdies on 5 and 8. She had a harder time on the back nine with bogeys on the 11th and the tricky 16th saw her wind up on even par, tied-23rd for the week.
