Tiger Woods produced a stunning surge in the opening round of the Deutsche Bank Championship on Friday but was overshadowed by 21-year-old South Korean Noh Seung-yul, who rocketed to a one-shot lead.
Noh tore apart the TPC Boston course with a bogeyfree nine-under-par 62 that left him one shot clear of American Chris Kirk in the second of the PGA Tour's four FedExCup playoff events.
Woods, Jeff Overton and Ryan Moore were tied in third place after the American trio shot matching 64s while world number one Rory McIlroy and American Bryce Molder were a further shot back.
Woods had earlier set the Boston crowds alight with a birdie blitz reminiscent of his glory days.
The 14-times major champion played his first eight holes in two-under par before carding six consecutive birdies to lead by as many as four shots at one stage.
Noh shot his lowest score of the year.
