GOLF CLUB HEAD
First Claim
1. A golf club head that, when oriented in a reference position, comprises:
- a striking face having a face center, a leading edge, and a virtual striking face plane generally parallel to the striking face;
a sole portion;
a top portion;
a hosel comprising a virtual hosel axis and an internal bore configured to receive a golf shaft, the internal bore including a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf shaft;
a rear surface opposite the striking face, the rear surface having an upper portion and a lower portion, the lower portion including a forward-extending recess;
an insert covering the recess such that a hollow portion is formed by the insert and the recess;
a loft L no less than 40°
;
a virtual vertical plane perpendicular to the striking face plane and passing through the face center; and
a club head center of gravity spaced from the virtual vertical plane in the heel-to-toe direction by a distance D1 that is no greater than 4.5 mm.

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.
