Inseoul Jiamanukoonkit of San Diego, California, won the 2026 Rolex Girls Junior Championship with a 54-hole tournament total score of 4-under-par 212.
Jiamanukoonkit, No. 66 in the Rolex AJGA Rankings, played steady golf across all three rounds, opening with a 3‑under-par start, following it with a 2‑under‑par 70, and closing with a 1‑over-par 73 to seal the victory.
