(Reuters) - New Zealand's Lydia Ko has split with long-time coach Guy Wilson, who started working with the golfing prodigy as a five-year-old novice and helped take her to number four in the world 11 years later.
Ko was given the green light in October to become a full member of the LPGA Tour from the start of the 2014 season after the governing body waived the 18-year-old age limit clause.
