BALL MARK
The indentation that a ball makes in the surface of the putting green upon landing. The softer the surface of the putting green, the more likely a ball mark is to result, and the more like that ball mark is to be larger.
This term is synonymous with the term "pitch mark" and is commonly confused with the term "divot". A divot refers to the mark left in the fairway or rough by the club. A ball mark only occurs on the green and the mark is made by the golf ball, not the club.
