WELLINGTON (Reuters) - Women's world number one Lydia Ko confirmed Gary Gilchrist as her new coach on Wednesday and said the South African had already "ripped apart" her swing ahead of her season debut in Australia next week.

New Zealander Ko said she had been working with Gilchrist for about a month, having parted ways with British swing guru David Leadbetter in December after a three-year association.
