TURNBERRY, Scotland (AP) Karrie Webb's latest comeback established a new standard of excellence on the LPGA Tour: the Super Slam.

Webb shot a 6-under 66 Sunday, rallying from three strokes behind to win her third Women's British Open title.

The 27-year-old Webb finished at 15-under 273, beating fellow Australian Michelle Ellis and Spain's Paula Marti by two strokes.

It was the sixth major championship in four years for Webb, who won the British Open in her rookie season of 1995 and again in 1997. The British became a major last year, replacing the defunct du Maurier Classic.

Webb wrapped up a career Grand Slam by winning the du Maurier, the Nabisco Championship, the U.S. Open and the LPGA Championship. By adding the British Open, she completed what has become known as the career "Super Slam" of five different majors in just five years.

"It's one of the best rounds that I can remember," Webb said. "The first major I won, the (1999) du Maurier Classic, I shot 66 in the final round as well, and I birdied four out of the last five holes, so it wasn't as solid a round as it was today.

"Just right from the word go, I was hitting good iron shots and making a lot of putts."

The rest of the field seemed powerless to stop Webb on the rainsoaked Turnberry links.

Third-round leaders Carin Koch of Sweden and Jenny Rosales of the Philippines were no match. Rosales shot a 1-over 73 and tied for fourth, and Koch had a 74 to tie for eighth at 10 under.

Ellis shot a 68 and Marti had a 69 to finish tied for second at 13 under.

The top American finishers were Meg Mallon and Beth Bauer, who tied for eighth at 10 under.

Just four players - Webb, Se Ri Pak, Juli Inkster and Annika Sorenstam - have won 16 of the last 19 majors. Webb has won six of them, Pak four, Inkster four and Sorenstam two. Sorenstam failed to make the cut at Turnberry.

Webb became the first player since Mickey Wright in 1964 to win a major title four years in a row. Wright achieved that feat twice between 1957-64.

"I didn't know that," Webb said. "That feels great, too."

Webb, who missed the cut at the U.S. Open at Prairie Dunes last month, searched for an explanation for her return to form. "You work hard and you keep at it, and hopefully the things that you've been working hard at work out," she said.

Webb said she was inspired by playing Turnberry, a course that's on the rotation for the men's British Open.

"There have been a lot of great champions here at the (men's) British Open," Webb said. "To win here, on such a great golf course, is a dream come true."

Webb had to get past a large group of young rivals to win her sixth career major. She birdied three of the first four holes to move into a tie with Koch and Rosales, and seized the lead at No. 10, where she made a 20-foot birdie putt. She pushed the lead to two strokes with a 15-foot birdie putt on the 15th hole.

Ellis and Marti briefly got within a stroke of the lead, but they were unable to maintain the charge.

Webb added another birdie at 17, on a 12-foot putt. She was already in the clubhouse when her challengers began to falter.
