Gavin Green, Kiradech Aphibarnrat and Jordan Smith shared the first-round lead at the Singapore Classic after shooting 8-under 64s on Thursday. Green, from over the border in Malaysia, holed a 40-footer for eagle at No. 3 and birdied seven of his last 12 holes late in the day to join Thailand's Aphibarnrat and England's Smith in a tie for first. Smith, the world No. 88 and coming off a second-place finish at the Jonsson Workwear Open two weeks ago on the European tour, was bogey-free around Laguna National Golf Resort Club and finished with an eagle at the par-5 last.
