Tiger Woods shot a seven-under-par 64 at the TPC Boston golf course to claim a share of the early first-round lead in the Deutsche Bank Championship on Friday.
Also shooting a 64 was American Jeff Overton. Two shots back of the leaders are Australian John Senden and South African Louis Oosthuizen, along with Korea's Seung-Yul Noh, who is among half the field still on the course.
A group of five golfers, including American Dustin Johnson as well as England's Ian Poulter and Luke Donald, are three off the lead after recording a 67.
Woods, who started his round on the back nine, birdied two of four holes to open the round. He birdied No. 18 as well as Nos. 1-5 after making the turn. His only bogey came on No. 9 to close his round.
