Abstract
A golf club head includes a striking face having a face center and defining a face plane. A vertical center plane is perpendicular to the face plane and passes through the face center. The golf club head further includes a hosel configured to receive a shaft and defining a hosel axis. The golf club head mass is between about 250 g and 320 g, a loft, L, is no less than 39°, a club head center of gravity is spaced rearward from the face plane by a distance, D5, such that D5≤7.69 mm-0.074 mm/°*L, and spaced from the vertical center plane by a distance, D7, that is no greater than 5 mm. A moment of inertia, Iyy, measured about an axis extending in the heel to toe direction and passing through the center of gravity, is no less than 1000 g*cm2.
