John Rollins, Jason Bohn, Carl Pettersson, Billy Andrade and Olin Brown all shot rounds under-par Sunday to share the lead at 10-under-par 203 heading into a Labor Day finish at the TPC of Boston.
Rollins fired the best round among the leaders at 8-under 63 and held the clubhouse lead alone for more than four hours. The 30-year-old closed with a course-record 28 on the back nine.
Among the leaders, only Andrade (69) and Browne (70) have more than one career PGA title. Bohn (67) won earlier this year at the B.C. Open -- the only victory among this fivesome in 2005.
Pettersson (68) is perhaps the most unlikely leader among the group. The 28- year-old Swede hasn't finished higher than a tie for 15th this year, and his best-ever finish on the PGA Tour was as runner-up to Woods at the 2003 Buick International.
There are 10 players within three strokes of the leaders after three rounds. Joey Sindelar (69) and Kent Jones (63) share sixth place at 9-under-par 204, one stroke ahead of four players tied for eighth.
Rollins, who is ranked 90th on the money list, holed out from a bunker for eagle at the 18th to claim the clubhouse lead. He finished his round with nine birdies and three bogeys.
'We have one more round to go so I've got to get ready for tomorrow and hopefully continue the good luck I've had on the back nine,' said Rollins, who won the 2002 Bell Canadian Open for his only tour victory.
Bohn collected seven birdies on the day, including four straight to end his round. Outside of his victory at the B.C. Open in July, he hasn't finished higher than a tie for 11th this year.
'Tomorrow is the day to think about tomorrow, not today,' said Bohn, who is 61st on the money list.
Pettersson earned a share of the lead with a birdie at 18, his fifth of the round. He was even-par on the front nine Sunday and played the back nine at 3 under to climb the leaderboard.
'A little nervous today because I haven't played very good this year, but as the round went on I got more comfortable and I felt fine,' said Pettersson, who is No. 159 on the money list. 'I hope I can keep that up tomorrow.'
Andrade opened and closed his round with a birdie, and in between the 41-year- old four-time champion collected 16 consecutive pars.
'I was pretty proud of making the birdie on last because I knew 10 under was a lot better than nine with everybody bunched up,' said Andrade, who ranks 57th on the money list. 'I liked way I played. I was very confident out there today and I'm looking forward to tomorrow.'
Andrade hasn't won since the 2000 Invensys Classic. His best finish this year is a tie for second at the MCI Heritage in April.
'I'm getting these feelings,' admitted Andrade. 'I'm feeling great about the way I'm handling myself. It's like I haven't played bad in a while. I feel like I'm rolling in the right direction, so I am ecstatic.
'I can't wait. I'm ready to go right now. I love this position. I'm going to go for it tomorrow and I'm going to play exactly the same way I played today and the first two days, and we'll see what happens.'
Browne carded three birdies and two bogeys in his round. After sharing the overnight lead with Jeff Brehaut at minus-9, he is in position to win for the first time since collecting the last of his two titles at the Colonial in 1999.
'I think I won't think about that much until I'm coming down the stretch tomorrow,' said Browne, who is 119th on the money list. 'But very pleased to be in this position.'
