EDINA, Minn. — Stacy Lewis is making her professional debut one to remember.

Nineteen days after she turned pro, Lewis showed the poise of a veteran Saturday at Interlachen with no bogeys and a 6-under 67 that gave her a one-shot lead over Paula Creamer going into the final round of the U.S. Women's Open.

Lewis, a former NCAA champion at Arkansas, might have been the only one not surprised to see her name atop the leaderboard.

"I've accomplished my goal for the week," Lewis said. "It was just to put myself in contention. And whatever happens tomorrow, it happens."

She will have to hold off a half-dozen players within four shots of the lead, starting with Creamer.

Creamer is two years younger but already in her fourth season on the LPGA Tour with six victories, enough for some to already anoint the 21-year-old product of a golf academy as the best player without a major. She had a chance to share the 54-hole lead with Lewis until missing a 6-foot birdie putt on the 18th for a 69.

Lewis was at 9-under 210, setting up an All-American final group at the U.S. Women's Open for the first time in five years.

Helen Alfredsson of Sweden, 15 years removed from her Women's Open heartache, stayed close to the lead throughout an afternoon of scattered clouds and came in at 71 to finish two shots out of the lead at 7-under 212, along with Inbee Park (71).

In-Kyung Kim had a 69 and was another shot behind, while eight-time LPGA Tour winner Mi Hyun Kim had a 70 and was at 214.

Annika Sorenstam, the three-time Open champion retiring at the end of the year, wasted another day filled with birdie opportunities by converting only two of them in a round of 72 that left her seven shots behind.

BUICK OPEN: At Grand Blanc, Mich., Daniel Chopra made a 15-foot birdie putt on the final hole after Dudley Hart bogeyed it, giving the Swede a two-shot lead with one round left in the Buick Open at Warwick Hills Chopra, the winner of the season-opening Mercedes-Benz Championship, had a 16-under 200 total.

COMMERCE BANK CHAMPIONSHIP: At East Meadow, N.Y., Loren Roberts remained in position for his first Champions Tour victory of the year, shooting a 3-under 68 to extend his lead to two strokes in the Commerce Bank Championship.

FRENCH OPEN: At Saint-Quentin-en-Yvelines, France, Spanish qualifier Pablo Larrazabal shot a 4-under 67 to take a three-stroke lead in the French Open.
