Thailand’s Chapchai Nirat took a two-shot lead in the first round of the Saudi Open after carding a seven-under 64 at the Riyadh Golf Club yesterday. Starting on the back nine, Nirat registered one eagle and seven birdies offset by two bogeys as the 40-year-old seeks his first Asian Tour title since 2014. Nirat leads compatriot and amateur teen golfer Ratchanon Chantananuwat and Mexico’s Luis Carrera, who are tied at five-under. The Saudi Open, which has a $1 million prize fund, is the season-ending event on the Asian Tour.
