Aurora, Ill. ? No record seems safe from Annika Sorenstam.

A little more than a year after shooting the first 59 in LPGA history, Sorenstam matched the best 54-hole score ever on the tour in winning the inaugural Kellogg-Keebler Classic on Sunday.

Sorenstam fashioned a 21-under-par 195 with a sizzling finish to win by 11 strokes, the largest margin on the tour this year.

So which was more surprising: 21 under or winning by 11?

“You tell me,” Sorenstam said. “Obviously, I’m very pleased with the way I have played this week.”

It was the fourth tour win of the season and 35th overall for Sorenstam, who closed with a 7-under 65, and it set her up for a strong run at the tour’s second major, the LPGA Championship starting Thursday at the DuPont Country Club in Wilmington, Del.

Sorenstam, who also opened the season with a playoff victory in an international event in Australia, won the first major, the Kraft Nabisco Championship in March.

Sunday, she matched the best 54-hole winning score in relation to par. Wendy Ward was 21 under in the 2001 Wendy’s Championship in New Albany, Ohio. Had Sorenstam not lipped a couple of putts early in her round, there’s no telling how low she might gone.

“To shoot 65 on Sunday, I’ll take that any day,” said Sorenstam, who set or tied 30 LPGA records last year.

Danielle Ammaccapane, Michele Redman and Mhairi McKay finished 10 under. Redman closed with a 68, McKay a 70 and Ammaccapane a 71, finishing with two birdies to pull into the tie. Kris Tschetter (68) and Candie Kung (70) were 9 under.
