Wayne Levi's 62 was the best score of his 13-year PGA Tour career, provided him with the first round lead in the $1 million Byron Nelson Classic and set a record on the storm-ravaged TPC at Las Colinas.

But it could have been better, Levi said; maybe even should have been better."I left two putts short dead in the heart of the hole," he said Thursday. "And there was that par-five. I was just in front of the green in two and I didn't birdie.

"That's three strokes right there," he said.

And it was by that margin - three strokes - that he missed the PGA Tour's all-time single-round scoring record, 59, set by Al Geiberger in 1977.

But Levi promised that he would reach that mark eventually.

"I know that before I finish I will shoot in the 50's . . . definitely," said Levi, who scored the last of his eight career victories in 1985.

Levi tied the course record set by Bob Lohr in 1987 with a 15-foot birdie putt on the final hole, a putt he said he probably shouldn't have attempted.

"It was so dark, I couldn't really see the line on the putt. I probably shouldn't have putted it, but I didn't want to come back at the crack of dawn tomorrow," said Levi, who was with Lee Trevino in the last group to complete play before darkness fell.

Trevino, the 49-year-old gearing up for the Seniors Tour, had a five-under-par 65 on the saturated course.
