Golf club heads and methods to manufacture gulf club heads
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head includes a top portion having a heel-side portion, a toe-side portion, and a raised central top portion with an opening. A shoulder portion extends inward toward the opening and a crown portion is attached to the shoulder portion and covers the opening. The bottom portion includes a central protrusion between a heel-side dividing plane and a toe-side dividing plane, a toe-side protrusion between the toe-side dividing plane and a toe-side bounding plane, and a heel-side protrusion between the heel-side dividing plane and a heel-side bounding plane. A distance between the toe-side dividing plane and the heel-side dividing plane is about equal to a diameter of a golf ball. Other examples and embodiments may be described and claimed.
