The Castlewarden golfer closed with a four-under-par 67 to finish on seven-under overall.
Kildare golfer Lauren Walsh produced the best finish of her LPGA career after claiming third place at the ShopRite LPGA Classic in New Jersey.
The Castlewarden golfer closed with a four-under-par 67 to finish on seven-under overall, just two shots behind winner Celine Boutier of France.
Walsh made a strong start with two early birdies and recovered from her only dropped shot of the day to remain in contention throughout the final round.
A closing birdie secured a breakthrough podium finish on the American tour.
It was also a positive week for Irish golf, with Leona Maguire finishing tied ninth and Stephanie Meadow ending the tournament tied for 21st.
Walsh's third-place finish marks a significant milestone in her rookie LPGA season and provides a major confidence boost ahead of the summer schedule, including a return home for the KPMG Women's Irish Open later this year.
