I've reverted this change (see https://www.openstreetmap.org/changeset/161725911 for details) because of two problems. The first is that history was destroyed by deleting someone else's existing work. That is frowned on unless absolutely necessary. The other problem is that you extended the fairway into the green instead of making them butt up against each other. 

See https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dgolf_course#Common_mapping_pitfalls for examples of golf course mapping that should be avoided.
