Scott Simpson made an eagle and five birdies for a seven-under-par 64 to tie the Kingsmill course record and take a two-shot first round lead in the $350,000 Anheuser-Busch Classic today.
Defending champion Calvin Peete, Tom Weiskopf, Terry Diehl and Sammy Rachels each shot 66 in the 100-degree heat to share second place.
"I was not expecting very much today," said Simpson, who missed a short putt on the 72nd hole of the Kemper at Congressional that would have won the tournament, before losing in a playoff.
Simpson said he spent 10 days recently in Hawaii and didn't take his clubs with him.
"I didn't make a birdie shooting 75 in the (Wednesday) pro-am. I've been working on tempo. It was the best ball-striking round I've had in a long time."
Simpson birdied the second hole, knocked in a 70-yard sand wedge for eagle on the par-5 third, and added birdies at the seventh and ninth holes for five-under-par 31.
He saved par from a bunker at the 10th, made birdie putts at the 14th and 17th, and completed his round without a bogey.
Peete, who withdrew from last week's British Open because of a pulled back muscle suffered in June, said he felt no pain, and the searing heat helped keep his back loose.
"There was no question whether I could play here. The question was, how good I would be able to play," said Peete. "The back was stiff Monday but it felt good today.
"I'm used to the heat because I used to play in south Florida. You have to play with more patience in the heat, pace yourself."
Peete, who did not have a bogey in his first two rounds last year, escaped again today. He blasted out of a greenside bunker and sank an eight-foot putt on the opening hole.
Peete leads the PGA in percentage of fairways hit and was perfect in that department today. He made three birdies for three-under-par 33 on the front nine, and went five under with birdies on the 10th and 14th.
Rachels shot 33 on the back nine he had never seen before. He sank a 50-foot putt for eagle on the third hole and made the last of his six birdies by sinking a four-foot putt on the 18th.
Diehl completed his round by three-putting the ninth green from 20 feet for his third bogey, after making an eagle and six birdies. Standing over a two-foot second putt on his final hole, Diehl was startled by an announcer introducing Bruce Leitzke hitting off the nearby first tee. Diehl backed off from the putt, then hit it and it rimmed out. He holed out a wedge for eagle at the 15th.
Weiskopf, who missed the cut here last year, closed with a four-under-par 31 on the back nine.
Pat McGowan double-bogeyed his final hole and was tied at 67 with PGA leading money winner Hal Sutton, Ed Dougherty, Bill Sander, Chip Beck and Tim Norris.
Mike Wynn led area players with 71, followed by Lee Elder with 72, Tony DeLuca, 75, and Woody FitzHugh, 80.
