NORTON  - Seung-Yul Noh capped a flawless nine-under 62 with two birdies on Friday to seize a one-shot first-round lead in the Deutsche Bank Championship, the second stop in the US PGA Tour playoffs.

South Korea's Noh, playing in more testing afternoon conditions, roared past early pace-setters Tiger Woods and Jeff Overton, who had shared the morning clubhouse lead on 64 but ended the day sharing third place alongside Ryan Moore and behind Noh and American Chris Kirk -- who carded an eight-under 63 at the TPC Boston. Noh nabbed his first birdie of the day on the par-five second, then reeled off four straight birdies from the fourth. Four birdies coming home included back-to-back efforts at 17 and 18 -- where he landed a wedge five feet from the pin.

Woods, too, knows that after enduring some wobbly weekend play this season. Woods has won three times this season, but he has also seen several title challenges unravel on the weekend. He shared the halfway lead at two major championships only to falter and last week at The Barclays he stumbled home with a 72-76.
