Turnberry, Scotland ? Karrie Webb will have to overcome a three-shot deficit and a packed leaderboard to win a third Women’s British Open title.

Webb shot a 2-under-par 70 Saturday for a three-round total of 9-under, three strokes behind co-leaders Carin Koch of Sweden and Jenny Rosales of the Philippines.

Koch made a 30-foot birdie putt at No. 18 for a 4-under 68, tying Rosales, who shot a 65 to get to 12-under 204.

Spain’s Paula Marti shot a 69 and 19-year-old LPGA rookie Natalie Gulbis had a 67. They were two strokes back at 10-under 206.

Michelle Ellis (68), Beth Bauer (70), Tina Barrett (70), and Candie Kung (71) were tied with Webb, who is trying to become the first player since 1964 to win a major four years in a row.

“Obviously, I’d like to be leading, but three shots isn’t too far behind on this golf course,” Webb said. “If we could get a bit of wind up tomorrow, it definitely could go any way.”

Webb has 11 come-from-behind victories in her career, all from two strokes or more. With a victory, the 27-year-old Webb can become the first golfer since Hall of Famer Mickey Wright to win majors in four straight years. Wright achieved the feat twice between 1957-64.
