Long before she was hoisting multimillion-dollar checks and etching her name into the bedrock of the LPGA Tour’s record books, Atthaya Thitikul was a 14-year-old amateur with an impossibly smooth swing and a preternatural calm.

In July 2017, at just 14 years, 4 months, and 19 days old, the golfer affectionately known as Jeeno captured the Ladies European Thailand Championship. The victory made her the youngest player to ever win a professional golf tournament—a distinction she held until 2023—and heralded the arrival of a generational talent. By the summer of 2019, she had ascended to the pinnacle of the amateur game, spending a total of 12 weeks as the world’s top-ranked amateur.

But it was her transition to the professional ranks that truly showcased the depth of her prowess. Thitikul broke through on the United States-based LPGA Tour in March 2022 with a victory at the JTBC Classic. By September of that year, the 19-year-old phenom had already amassed two LPGA victories and four titles on the Ladies European Tour. Her meteoric rise culminated that Halloween, when she officially became the No. 1 golfer in the Women’s World Golf Rankings, capping off a season that earned her LPGA Tour Rookie of the Year honors and establishing her as the fastest-rising star in the sport.

Rather than buckling under the weight of early expectations, Thitikul has only accelerated. The closing months of the 2024 and 2025 seasons served as a definitive coronation. In both years, she triumphed at the highly competitive season-ending CME Group Tour Championship, securing a staggering $4 million prize each time.

Her 2025 campaign, in particular, was a masterclass in consistency and execution. She topped the LPGA money list and secured her second Vare Trophy—having first won it in 2023—by posting a 68.68 scoring average, the lowest in the history of the tour. By August 2025, she had rightfully reclaimed her throne as the No. 1 player in the world.

For Thitikul, the prodigy who once dazzled the golf world as a teenager, the narrative is no longer just about how fast she arrived. It is about how thoroughly she intends to stay.
