Golf club heads and methods to manufacture golf 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 may include a body portion having an interior cavity, a toe portion, a heel portion, a front portion, a back portion, a top portion, and a sole portion. The body portion may include a ledge portion that extends from an upper back wall portion to a lower back wall portion of the back portion. The golf club head may include a face portion coupled to the front portion to close the interior cavity, a port on the body portion, a polymer material in the interior cavity, and a mass portion. A width of the ledge portion may be greater than a width of the body portion above a horizontal midplane of the body portion. A distance between a portion of the polymer material in the interior cavity and the face portion at a location vertically above the mass portion and below the ledge portion may be greater than a distance between the mass portion and the face portion. Other examples and embodiments may be described and claimed.
