Abstract: A golf club having improved visual feature recognition includes a golf club head coupled to a golf club shaft. The golf club head includes a hosel defining a bore, a sole, and a design attribute that is generally not capable of easy visual discernment. The bore has a first portion having a first diameter, a second portion having a second diameter that is smaller than the first diameter, and a transition from the first diameter to the second diameter. The bore extends through the golf club head to the sole, and the golf club shaft is disposed within the first portion of the bore and secured to the hosel. A polymeric plug is disposed within the bore between the golf club shaft and the sole. The polymeric plug includes a restraining feature that contacts the transition to prevent withdrawal of the polymeric plug through the sole, and is a color that corresponds to the design attribute.
