Preferred Lies are now on closely mown areas only (ie fairways, green approaches, tees and any closely mown paths).
Rule 25-2. Local Rule. With immediate effect and until further notice, a ball embedded or plugged in its own pitch mark in closely mown areas AND through the green, can be lifted, cleaned and dropped (not nearer the hole) without penalty as near as possible to the spot where it lay.
In other words - preferred lies on fairways, lift and drop if plugged in the rough.
