A rare showing of anger has powered Lydia Ko to the top of the leaderboard at the end of the second round at Australian Women's Open in Melbourne.
The world number one has finished in a share of the clubhouse lead after firing a three under round to sit at
six under par.
Ko said she channelled her frustration on the 15th and hit a crucial eagle.
She said she was annoyed by her performance on the previous hole and so hit an aggressive drive which came up trumps.
Ko sits at the top with South Korea's Ha Na Jang and Thailand's Ariya Jutanugarn.
