Alice Miller rolled in a 25-foot birdie putt on the 18th hole today for a two-under-par 70 that left her one stroke ahead of Judy Clark and Patty Sheehan following the third round of the $400,000 Nabisco Dinah Shore tournament, the richest event on the LPGA tour.

Miller had a slim lead at the 17th hole, but lost the advantage with a bogey and fell into a three-way tie for first with Clark and Sheehan.

On the par-5, 487-yard 18th, she dropped her third shot to within 25 feet, then sank the long breaking putt for the birdie.

Miller, who has had five top-10 finishes in seven tournaments this year, was at eight-under-par 208 entering Sunday's final round on the Mission Hills Country Club course. Clark, who shot 72, and Sheehan, who had a 71, were tied at seven under.

Miller, 28, had four birdies and two bogeys over the 6,275 course.

"It was like different rounds today," Miller said. "I was playing real solid at first, then I really struggled coming back in, hitting bad iron shots and bad putts.

Clark also bogeyed No. 17, her first bogey of the round. Sheehan had birdied the 13th hole, then had pars the rest of the way.

Four shots back were Jan Stephenson and Denise Strebig, who each shot 73, and Lauri Peterson, who shot 69. Another stroke back were Pat Bradley (69), Betsy King (75) and Beth Solomon (72).

Second-round leader Muffin Spencer-Devlin shot a 76 and was six strokes out of the lead.

Defending champion Juli Inkster, who would win a $1 million bonus with a repeat victory, shot 72 and was 11 back.
