Karrie Webb successfully defended her Nichirei Cup World Ladies title with solid if unspectacular golf Sunday, coasting to a 6-shot victory with the help of a disastrous round by overnight co-leader Carin Koch of Sweden.

Webb, who began the final round tied with Koch, shot a 1-under-par 71 in gusting winds at Tokyo Yomiuri Country Club to finish the 72-hole event at 10-under 278 -- two strokes shy of the tournament record she set last year.

Webb fell two strokes behind after her bogey on the opening hole coupled with Koch's birdie at No. 2, but quickly rebounded to make three straight birdies from the fourth. She then found herself two shots in front after Koch bogeyed the eighth.
