That turned out pretty well.
Estes went wire-to-wire en route to winning his first - and only - PGA Tour event in the 1994 Texas Open.
Deja vu in Germantown, Tenn.? Estes hopes so.
Estes had 10 birdies in matching the TPC at Southwind course record, set in the final round in 1993.
Tom Byrum was 7-under-par with two holes left when play was suspended by darkness at 8:55 p.m. ET.
Richie Coughlan, Brent Schwarzrock and Tommy Tolles, who were all 6-under, were among the 30 players still on the course when play was stopped.
John Riegger, who spent the past two years on the Buy.Com Tour, matched his best round ever on the PGA Tour with a 65. J.P. Hayes, Chris DiMarco, Paul Goydos, Sean Murphy and Cliff Kresge all had 66s.
Rain forced a two-hour delay before the first group teed off on Thursday. Under lift-clean-and-place rules, Estes birdied four of the first five holes and six of the first eight.
He made the turn with a share of the lead at 6-under and continued his torrid play on the back nine. Estes recorded four more birdies on the outward half to tie the best score of his career, which came in 1991 at the Chattanooga Classic.
It was an all-to-familiar day for Phil Mickelson. The world's No. 2-ranked player was at 3-under and tied for the early lead at the turn when he ran into trouble.
He hit his tee shot into the water on the par-3 11th and then put a wedge into a bunker for a triple-bogey. Mickelson also had trouble off the tee on the par-4 18th, putting his tee shot into the lake down the left side of the fairway. He took a drop and then missed a long putt for par, finishing with a 70.
