Abstract: A golf club head includes a striking face, a sole portion, a top portion, a hosel, a rear surface, a loft no less than 40°, a virtual vertical plane, and a center of gravity. The striking face has a face center, a leading edge, and a virtual striking face plane. The hosel includes an internal bore configured to receive a golf shaft and includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf shaft. The rear surface is opposite the striking face and has an upper portion and a lower portion, the lower portion including a forward-extending recess. The insert covers the recess forming a hollow portion. The virtual vertical plane is perpendicular to the striking face plane and passes through the face center. The center of gravity is spaced a distance from the virtual vertical plane in the heel-to-toe direction.
