Various embodiments of a golf putter having a putter head attached to an elongated shaft with the putter head defining a retention cavity configured to engage and retain a golf ball therein are disclosed. The retention cavity is formed along the back region of the putter head and is configured to have a diameter that is slightly less than the diameter of a regulation sized golf ball such that the golf ball is retained therein when urged into the confines of the retention cavity by the putter head. The putter head further includes an alignment aid that cooperates with the retention cavity to assist in aligning the golf putter during a putting stroke.
