WILLIAMSBURG, JULY 11 -- John Cook scrambled from a greenside bunker to shoot par at the 18th hole for a 66 and a one-shot lead over resurgent Bobby Clampett heading into the final round of the Anheuser Busch-Classic at Kingsmill.

Cook, hoping for his first PGA Tour victory since the 1983 Canadian Open, has a 54-hole total of 14-under-par 199.

Clampett made birdies on 14, 15 and 16 and then capped off his 6-under-par 65 with an eight-foot birdie on the final hole.

Tied at 12-under-par 201 were second-round leader Tim Simpson (69 today), Mark McCumber (67) and Scott Hoch (68). Vance Heafner, who finished with four birdies for 66, is tied at 202 with first round co leader Tom Sieckmann (69). D.A. Weibring shot 66-205.

Cook, with a towel draped around his neck to keep cool in the searing heat, had been rock-solid through the round, with no bogeys and six birdies. He hit his approach shot to the final green into the trap on the left. He blasted out to eight feet above the hole and sank the downhill putt for par.

"That capped off a pretty good day," said Cook, who has won twice on the PGA Tour. "I struck the ball well and never got impatient, which I tend to do sometimes. I'm starting to gain a little more confidence in my golf swing."

Cook, who started the day one stroke behind Simpson, took the lead with birdies on the second and third holes.

He said he got a good break when his drive hit an asphalt cart path and ended up up in the fairway on the 10th hole. He birdied that hole, then the 11th and 15th before parring in.

Cook came on tour in 1980 out of Ohio State after winning the U.S. Amateur and had a can't miss label pinned on him. Three years ago he suffered wrist and elbow injuries that linger.

Cook considers himself as a shotmaker rather than a scrambler, and he pointed out shotmakers such as Calvin Peete (twice) and John Mahaffey have won here. He might also be remembering that several times golfers have come from as far back as six strokes on the final day to win here.

Cook has finished in the top 10 four times, has won almost $105,000 this year and can surprass $1 million in career earnings with a win here.

Clampett finished his brilliant round by hitting out of the rough six feet from the final hole for his seventh and final birdie.

Simpson opened with seven pars and Hoch and Cook overtook him early. Simpson then made birdie at the eighth hole. He made two birdies and a bogey on the back nine and said he could have shot another low round, like his Friday 65, had his hot putter not turned cold. "I just didn't make the same putts," he said.

Hoch, who also started one behind, birdied the first and third holes to briefly hold the lead, but he fell back with bogeys at four and nine.
