Abstract: A marker for marking the position of a golf ball that is to be lifted from the surface of a putting green. The marker includes a thin gage planar body which defines an opening of at least semi-circular configuration which opens onto one edge of the planar body, and which is sized so that the marker can be dropped vertically over the golf ball onto the surface of the putting green.

Abstract: An apparatus for practicing golf putting strokes including a putting surface member for receiving a golf ball to be putted and a swing path defining member which extends angularly from the putting surface part and lies in a plane which defines a normal and desired putter swing path. The swing path defining part is laterally offset from the intended swing path of the putter to provide a person using the apparatus with a visual indication of a normal swing path to serve as a guide while making unfettered practice swings with the putter. The swing path defining member includes an unobstructed planar member and a flange which is mounted on the putting surface member and supports the unobstructed planar member at an angle of substantially 72.degree. with respect to the putting surface member.
