Atthaya Thitikul has officially supplanted Jin Young Ko as the No. 1 player in the world. Thitikul, 19, becomes the second teen to ascend to No. 1, following in the footsteps of Lydia Ko, who was 17 years, 9 months and 9 days when she reached the top spot in 2015.
Ko, who has held the top spot since Jan. 31, 2022, first became No. 1 in April 2019 and has spent 152 total weeks atop the rankings. Lorena Ochoa holds the record at 158 weeks.
Thitikul, a rookie who has two wins this season, also joins Ariya Jutanugarn as the only Thai players to reach No. 1. Thitikul joins Sung Hyun Park as the only rookies to reach no. 1. She currently leads the Louise Suggs Rookie of the Year race and is in the mix for LPGA Player of the Year.
“It means a lot for my team, my family, my supporters and myself. It is such an honor to have my name at the top amongst the biggest names of the game,” said Thitikul in a release. “It is very special to get to the top but it is much harder to retain it. I still have a lot to learn from all the legends and current players both on and off the course. I will continue to work hard for my family, my team, my fans and my country.”
Prior to joining the LPGA, Thitikul became the youngest player ever to win the Ladies European Tour’s Race to Costa del Sol in 2021 while also securing Rookie of the Year and Player of the Year honors. At 14 years, 4 months and 19 days, Thitikul also became the youngest golfer to ever win a professional golf tournament with her victory at the LET’s Thailand Championship in 2017.
