Golf club head
A golf club head includes a striking face having a face center and a virtual striking face plane generally parallel to the striking face. The golf club head further includes a sole portion, a top portion, and a rear portion. A hosel portion includes a recessed region with at least a portion of the recessed region located in an outer portion of the hosel portion. A first virtual vertical plane is perpendicular to the virtual striking face plane and passes through the face center. A center of gravity is spaced from the first virtual vertical plane in a heel-to-toe direction by a distance no greater than 6.0 mm. According to another aspect, the hosel portion includes a second material having a second density that is lower than a first density of a first material included in the striking face.

a top portion;
a rear portion;
a loft L no less than 40°;
a hosel portion including a hosel exterior surface and an internal bore configured to receive a golf shaft;
a recessed region, wherein at least a portion of the recessed region is located in the hosel exterior surface;
a first virtual vertical plane perpendicular to the virtual striking face plane and passing through the face center; and
a club head center of gravity spaced from the first virtual vertical plane in a heel-to-toe direction by a distance D 1 that is no greater than 6.0 mm and spaced from the virtual striking face plane by a minimum distance D 2 no greater than 2.0 mm.
2. The golf club head of claim 1 , wherein at least a portion of the recessed region is located where the hosel portion meets at least one of the sole portion, the rear portion, and the top portion.
3. The golf club head of claim 1 , wherein the recessed region includes one or more trusses separating a plurality of sub-recesses in the recessed region.
4. The golf club head of claim 1 , wherein the recessed region gradually transitions to at least one of a bottom surface of the sole portion and the hosel exterior surface.
5. The golf club head of claim 1 , wherein the recessed region opens to a rear recessed region of the rear portion.
6. The golf club head of claim 1 , wherein the recessed region gradually transitions to at least one of an exterior surface of the top portion and the hosel exterior surface.
7. The golf club head of claim 1 , wherein the recessed region comprises a maximum depth of no less than 0.5 mm.
8. The golf club head of claim 1 , wherein the striking face further includes a plurality of scorelines having a heel-most extent and a toe-most extent, and wherein the golf club head further comprises:
a second virtual vertical plane perpendicular to the striking face plane and passing through the heel-most extent of the plurality of scorelines, and
wherein the recessed region is entirely located heel-ward of the second virtual vertical plane.
9. The golf club head of claim 8 , further comprising:
a third virtual vertical plane perpendicular to the striking face plane and passing through the toe-most extent of the plurality of scorelines; and
a toe portion recessed region that is entirely located toe-ward of the third virtual vertical plane.
10. The golf club head of claim 9 , wherein at least one of the recessed region and the toe portion recessed region are at least partially filled.
11. The golf club head of claim 1 , wherein the distance D 1 is no greater than 5.5 mm.
12. The golf club head of claim 1 , wherein the distance D 1 is no greater than 5.0 mm.
13. The golf club head of claim 1 , wherein the distance D 2 is no greater than 1.0 mm.
14. The golf club head of claim 1 , wherein the recessed region is at least partially filled.
15. A golf club head that, when oriented in a reference position, comprises:
a striking face having a face center and a virtual striking face plane generally parallel to the striking face, the striking face including a first material having a first density;
a sole portion;
a top portion;
a rear portion;
a loft L no less than 40°;
a hosel portion including an internal bore configured to receive a golf shaft, the hosel portion including a second material having a second density that is lower than the first density of the first material;
a first virtual vertical plane perpendicular to the virtual striking face plane and passing through the face center; and
a club head center of gravity spaced from the first virtual vertical plane in a heel-to-toe direction by a distance D 1 that is no greater than 6.0 mm and spaced from the striking face plane by a minimum distance D 2 no greater than 2.0 mm.
16. The golf club head of claim 15 , wherein the hosel portion includes a recessed region that is filled with the second material.
17. The golf club head of claim 15 , wherein the second material forms a sleeve around a circumference of the hosel portion.
18. The golf club head of claim 15 , wherein a majority of the second material by volume is located on a heel-ward side of the hosel portion.
19. The golf club head of claim 15 , wherein the hosel portion includes an indication on an exterior surface of the hosel portion of a reduced weight due to the second material.
20. The golf club head of claim 15 , wherein the distance D 1 is no greater than 5.5 mm.
