A golf club head includes a center of gravity spaced less than 5 mm from a vertical center plane that is perpendicular to a striking face plane and extends through a striking face center. The golf club head also includes a first component having a first melting point and a first density and a second component having a second melting point higher than the first melting point and a second density less than the first density. And the second component (i) is at least partially encapsulated by the first component, (ii) extends into a hosel portion below a hosel bore, and (iii) has a mass less than about 5 g.
