SOUTH KOREAN Jeong Jang was the player to catch at the midway stage of the Weetabix Women's British Open at Royal Birkdale.

She is still seeking a first win in five years on tour, but the South Korean's second round of 66 saw her move four shots clear of the field on 10 under par.

Louise Stahle, the Swede who has won the British Women's Amateur Championship for the past two years, shot a terrific seven-under-par 65 to stand in second place on six-under, while American Cristie Kerr was a further shot back on five-under.

Wales' Becky Morgan was another sharpshooter in the better second day conditions, although she did finish her seven-birdie 66 in the lashing rain.

On one-over-par 145, the 30-year-old was tied for 23rd and the leading British player alongside defending champion Karen Stupples, who had a 71, and Scot Catriona Matthew, who had a double-bogey seven at the 17th in a 72.

Michelle Wie, the 15-year-old American amateur, and Annika Sorenstam were both on two-under 142 and in a tie for eighth.
