I just played a course here in my home state two days ago and they had a plastic sleeve attached to the pin that went down to the bottom of the cup. There was enough room for the ball to go in the hole. It had another plastic piece where all you did was use your putter and pop the top piece of plastic to get the ball out of the whole. There was no touching of the pin or reaching in the hole to retrieve your ball. It’s hard to explain on here but it was a nice set up I thought. It’s just my option of course.
