Almost two months after splitting with David Leadbetter, Lydia Ko's expected to announce her coaching future in the coming fortnight, with her nearest rival's mentor the frontrunner.

According to the Golf Channel, the world number one has had a number of sessions with South African swing coach Gary Gilchrist.

Gilchrist's team has told NZME they aren't in a position to comment on the kiwi, though are happy to, once Ko makes an official announcement.

It'll make for a busy time for Gilchrist, who currently coaches two of Ko's nearest rivals, in world number two Ariya Jutanugarn, and world number four Shanshan Feng.
