An iron-type golf club head includes a body having a wall extending about an opening, a faceplate coupled to the body across the opening, first and second sets of apertures, and a fill material. The wall has an outer peripheral surface, a sole, a toe, a heel, a topline and a rear wall portion extending from the heel to the toe. The wall and the faceplate define a rearward-facing back cavity, and the sole, the rear wall portion and the faceplate define a lower cavity that is continuous with the back cavity. The first and second sets of apertures extend through the wall from the peripheral outer surface to, and are continuous with, the lower cavity. The first and second sets of apertures extend about first and second planes, respectively. The fill material substantially fills the lower cavity and the first and second sets of apertures.
