A five-under par round of 67 has pushed Karrie Webb into a share of the lead alongside compatriot Tamie Durdin and Korea&aposs Hyun Ju Shin at the ANZ Australian Masters. The Australian Open champion posted five birdies and a solitary bogey in her second round to move to the top of the leader board at the rain-shortened tournament, which has been reduced to 54 holes after monsoonal conditions on Thursday made the Royal Pines Resort course unplayable. After an opening round 69, Durdin began her round with a birdie on the third hole before committing a double bogey on the par 4 fourth hole. She managed to recover though with birdies on four of the next five holes and added two more on the back nine to finish as the early morning leader. Shin had another consistent day posting a four-under 68 to finish one stroke ahead of Taiwan&aposs Ya-Ni Tseng (69) and English woman Lisa Hall (69). A host of players are a further short behind at six-under par while big hitting Laura Davies shot a 69 to move to five-under for the tournament. First round leader Nikki Garrett slipped off the pace carding a one-over par 73 to finish the day four shots behind the leaders.
