The success in the season's first major however should come as little surprise. Last July when Thitikul was just 14-years-old, 4 months and 19 days she won the Ladies European Tour's Thailand Championship becoming the youngest player to ever win a professional tournament recognized by the world rankings system.

A native of Thailand, Thitikul, earned her spot into the field at the Dinah Shore Tournament Course with her February win at the inaugural Asia-Pacific Women's Amateur Championship.

Ranked 12th in the Golfweek/AmateurGolf.com Women’s Rankings, Thitikul closed with a final round 3-under 68 that followed up tallies of 71-71-72.

During the final round Thitikul rolled in five birdies why bogeying only twice. The birdies for Thitikul came on Nos. 2, 3, 10, 11 and for good measure the 18th.

The only other amateur to finish under-par was UCLA star Lilia Vu who at 3-under shared 40th. Vu, a four-time winner for the Bruins this season, was over-par after a first round 1-over 73 before carding three consecutive subpar rounds of 70-71-71.

For the first three days one of the main story lines of the ANA Inspiration was Stanford sophomore Albane Valenzuela. In a tie for fourth after the first round, Valenzuela was three back as deep into the tournament as the second nine on Saturday but eventually she faded to an even-par 59th place finish.

Junior ANA Inspiration winner Rose Zhang was the final amateur to make the cut, sharing 60th at 1-over.
