[quote=Yip123]Can you explain the plug ball rule, both on the fairway and off the fairway, thanks.[/quote]
Rule 25-2. Embedded Ball. A ball embedded in its own pitch-mark in the ground in any closely-mown area through the green may be lifted, cleaned and dropped, without penalty, as near as possible to the spot where it lay but not nearer the hole. The ball when dropped must first strike a part of the course through the green. "Closely-mown area" means any area of the course, including paths through the rough, cut to fairway height or less.

There is no relief for a plugged ball in the rough, unless there is a special local rule. (usually when a course is veru wet, perhaps in winter)
