Abstract
A golf club head includes a striking face having a face center and defining a face plane, a virtual vertical center plane perpendicular to the face plane and passing through the face center, a sole portion, a top portion, a heel portion, a toe portion, a hosel configured to receive a shaft, and a loft, L, no less than 39°. A center of gravity is spaced toe-ward from the vertical center plane by a distance, Dt, of greater than 0.0 mm. A moment of inertia, Iyy, measured about an axis extending in a heel to toe direction, parallel with a ground plane, passes through the center of gravity such that Iyy is no less than 1150 g·cm2.

A golf club head that, when oriented in a reference position relative to a virtual ground plane, comprises:
- a striking face having a face center and defining a face plane;
- a virtual vertical center plane perpendicular to the face plane and passing through the face center;
- a sole portion;
- a top portion opposite the sole portion;
- a heel portion;
- a toe portion opposite the heel portion;
- a hosel configured to receive a shaft and defining a hosel axis;
- a loft, L, no less than 39°;
- a center of gravity spaced toe-ward from the vertical center plane by a distance, Dt, of greater than 0.0 mm, the center of gravity spaced rearwardly from, and perpendicularly to, the face plane by a distance, D5, no greater than 2.25 mm;
- and
- a moment of inertia, Iyy, measured about an axis extending in a heel to toe direction, parallel with the virtual ground plane, and passing through the center of gravity, Iyy being no less than 1150 g·cm2.
