Singh eagled the par-5, 513-yard seventh hole and didn't have a bogey in an 8-under-par 63. He's two strokes ahead of Alexandre Kaleka, who closed with six birdies in the final seven holes for a 6-under 65.
Singh had only a birdie at the fourth hole and five pars to show as he approached the seventh hole. But his second shot on the par-5 ended up 30 feet from the hole and he made the putt for eagle.
He birdied No. 8 and made the turn at 4-under. He opened the back nine with three consecutive birdies and added another at the 14th. Four pars left him at 63 and in the lead.
