Sutherland on Friday reached the Buy.Com Tour record books when his 36-hole total of 127 matched the tour's record for low opening 36 holes and his six-shot lead also tied the Buy.Com Tour record.
It was a different story on Saturday as Sutherland opened with three bogeys in his first seven holes. Briggs did his part to cut into Sutherland's lead with two birdies and a bogey in his first seven to cut the margin to two.
'I just didn't play very well,' said Sutherland, who carded a 1-over 73 on Saturday. 'It's more of the way I expected to play the whole week. Win or lose, I would like to play better tomorrow.'
Sutherland stopped the bleeding with an eagle at the par-5 12th and a birdie at the next hole but Briggs matched him along the way with birdies in four of his first six holes on the back nine.
When Sutherland picked up back-to-back bogeys at 15 and 16, Briggs took the lead with a birdie at No. 15. Both players birdied 17 but Briggs dropped a shot at the last to fall into the tie for the lead.
'I haven't been in this position in a long time,' said Briggs, who has three runner-up finishes in his tour career. 'I held up really well today and am looking forward to the challenge tomorrow. It looks like we are going to have some fun.'
'I'm mentally tired,' said Sutherland, who is returning to competitive golf for the first time since shoulder surgery in March. 'I haven't had to concentrate like this in a while. When I should have been concentrating on a putt, I was looking at the mountains.'
