Keith Clearwater, 164th on this year's PGA money list, turned in a bogey-free six-under-par 66 yesterday in Marietta, Ga., to build a two-shot lead after three rounds of the Atlanta Golf Classic.

Clearwater, who hasn't won on the PGA Tour since capturing two events in his rookie season (1987), has a 54-hole score of 204, 12 under par, on the hilly 7,018-yard Atlanta Country Club course.

He leads by two shots over second-round leader Larry Mize, Nick Price and Wayne Levi. Mize, who had 15 pars, birdied the 18th to complete a 71; Price had a 69; and Levi capped an erratic round with a 40-foot downhill eagle putt for 68.

Mike Donald (68) and Howard Twitty (72) are tied at 208.

Clearwater, who started three shots behind Mize, gained a share of the lead with a 12-foot birdie putt on the 14th and took the lead alone when he sank a 20-footer on the par-3 16th.

He closed his round by tapping in for birdie, narrowly missing a chip-in eagle.

Clearwater won $320,000 in his rookie season, which featured victories in The Colonial and Centel Classic. He hasn't won $100,000 in any season since.

His best finish this year is 30th in the Tucson Open. He's missed the cut four times in 13 starts.

Levi, the 1985 winner, had the strangest round of the day -- one eagle, six birdies and four bogeys. "I got off to a shaky start, but kept myself together," he said. "Good things seem to happen to me in Atlanta."

Levi three-putted from 25 feet for his fourth bogey at 15, then got back into contention with a 12-foot birdie putt on 16, setting up the finishing eagle.

Price, who tied for second in last week's Colonial, had four birdies in a row beginning on No. 6 to take the lead halfway through the round. He had bogeys on Nos. 13 and 17, but scored a birdie-4 on the final hole.

Mize never got anything going. He had a birdie on 11, but gave the shot back when he bogeyed 13.

Tom Kite made a move with a 68 for a three-round total of 209.

LPGA: Pat Bradley's 10-foot birdie putt on No. 18 completed a 66 that provided a four-shot lead over Patty Sheehan after the third round of the Corning Classic in Corning, N.Y.

Bradley, who started three strokes behind 36-hole leader Alice Ritzman, birdied Nos. 2, 4, 7 and 9 to vault into the lead, then overcame a bogey at No. 10 with birdies at 12 and 15 to take charge.

The birdie at No. 18 allowed Bradley to keep a safe margin over Sheehan, who followed 16 pars with birdies at 17 and 18.

Senior PGA: Dale Douglass shot four-under-par 66 to take a one-stroke lead over Gary Player (68) and Charles Coody (68) after two rounds of the Bell Atlantic Seniors Classic at Chester Valley Golf Club in Malvern, Pa.
