Meadow, 27, birdied her final two holes at the tournament in Texas to secure her playing privileges for next season.

That included a 25-foot putt on the last that meant the Jordanstown native finished in a tie for sixth, eight shots behind winner Cheyenne Knight.

Meadow, needing to finish in the top 100, was 99th on the money list.

Having made a fast start to the week with an opening round of 63, Meadow faded slightly following rounds of 71 and 73.

She started Sunday with back-to-back birdies and, though a bogey at the fifth temporarily halted her momentum, further birdies at the ninth and 13th put her in a strong position.

Although her eagle putt on the 17th slid by, she made birdie and backed it up with another on the final hole to card a four-under 67 to finish on 10 under par.

Meadow punched the air in delight as her birdie putt on the 18th dropped into the hole.

Knight shot a five-under-par 66 on the last day to clinch her first LPGA Tour event on 18 under.

England's Georgia Hall also shot a final round of 66 to finish in a tie for fourth.

Meadow's compatriot Leona Maguire had earlier secured graduation to the LPGA Tour with a fifth-placed finish at the Symetra Tour Championship.
