In 2012, Ariya Jutanugarn of Bangkok, Thailand, won her fourth AJGA event at the 34th Polo Golf Junior Classic. After missing the cut for match play in 2011, Jutanugarn was determined to come back and prove herself.
Jutanugarn was tied for ninth heading into the final round of stroke play but quickly climbed to the top after birdieing four of the first six holes. She defeated Angel Yin of Arcadia, California, 5 & 4. Jutanugarn was the first reigning Rolex Junior Player of the Year to be victorious at the Polo Golf Junior Classic since Vicky Hurst in 2007.
Before winning her last junior and amateur event, Jutanugarn made herself a force to be reckon with in the AJGA. In 2012, Jutanugarn won the Thunderbird International Junior. Additionally, she defended her 2011 win at the 2012 Rolex Girls Junior Championship. Jutanugarn had eleven top-10 finishes throughout her AJGA career, which included runner-up at the 2011 Rolex Tournament of Champions.
Jutanugarn was a three-time Rolex Junior All-American in 2010, 2011 and 2012, as well as a two-time Rolex Junior Player of the Year in 2011 and 2012.
Since her AJGA career has ended, Jutanugarn has made her way to the big leagues, joining the LPGA Tour in 2015. She is currently No. 22 in the Rolex Rankings and No. 5 in the CME Ranking.
In July 2021, Ariya and her sister, Moriya, won the Dow Great Lakes Bay Invitational. They defeated defending champions Cydney Clanton and Jasmine Suwannapura by three strokes. This was Ariya's second win in the 2021 season and Moriya's second career victory. The sisters are also playing in the 2021 Amundi Evian Championship July 22-25.
