The Links Department has installed the three cup changing system on the greens until frost is no longer a concern. It consists of cutting three separate hole locations on each green such as front, middle and back with cup liners installed. A metal cap is the placed inside the cut holes that will sit flush with the surrounding green surface.
This will allow the links staff to change the pin positions by inserting the flag sticks in one of the other installed cups and also allow regular maintenance practices to continue such as mowing, de-dewing or spraying as needed. This allows the movement of pins when needed even during prolonged periods of frozen ground or inclement weather conditions or when links staff labour is at a minimum and during the frost delays and shotgun starts.
