1. A golf club head, comprising:

  • a club head body defining an interior cavity, a sole defining a bottom portion of the club head, a crown defining a top portion of the club head, a face defining a forward portion of the club head and including a striking surface, and a rear portion opposite the face;

    a sleeve for securing a shaft to the golf club head, wherein the sleeve has a threaded lower opening;

    a fastener has a threaded shaft adapted to engage the threaded lower opening of the sleeve to thereby attach the shaft to the golf club head;

    wherein the club head body has a head origin defined as a position on the striking surface at approximately a geometric center of the striking surface, the head origin including a head origin x-axis, a head origin y-axis, and a head origin z-axis;

    wherein the head origin x-axis is tangential to the striking surface and generally parallel to a ground plane when the club head is in an address position, further wherein a positive x-axis extends towards a heel portion of the club head body;

    wherein the head origin y-axis extends perpendicular to the head origin x-axis and generally parallel to the ground plane when the club head is in the address position, further wherein a positive y-axis extends rearward from the striking surface and through the rear portion of the club head body; and

    wherein the head origin z-axis extends perpendicular to the ground plane, and perpendicular to both the head origin x-axis and head origin y-axis when the club head is in the address position, further wherein a positive z-axis extends generally upward from the head origin;

    a plurality of weight ports positioned in the sole of the golf club head, comprising;

    a first weight port configured to retain a first weight, the first weight port defining a first central axis that extends through the sole and the crown of the golf club head;

    a second weight port configured to retain a second weight, the second weight port defining a second central axis that extends through the sole and the crown of the golf club head;

    a third weight port configured to retain a third weight, the third weight port defining a third central axis that extends through the sole and the crown of the golf club head;

    wherein the first weight port is positioned a first distance from the head origin, the second weight port is positioned a second distance from the head origin, and the third weight port is positioned a third distance from the head origin;

    wherein, as measured along the head origin y-axis, the first distance is less than the second distance, and the first distance is also less than the third distance;

    wherein the second weight port is positioned toeward of the first weight port and the third weight port is positioned heelward of the first weight port;

    wherein the first, second, and third weight ports comprise internal threads that correspond to external threads formed on the first, second, and third weights;

    wherein the first, second, and third weight ports are similarly sized such that the first, second, and third weight ports are configured to interchangeably receive the first, second, and third weights;

    wherein the club head body is at least partially comprised of a metal alloy;

    wherein the golf club head has a height not exceeding 46 mm, and an above ground center-of-gravity location, Zup, not exceeding 19 mm;

    wherein the face has a loft angle exceeding 13 degrees; and

    wherein at least one of the plurality of weight ports is positioned within 30 mm of a nearest portion of a forward edge of the sole of the golf club head; and

    the first, second, and third weights are positioned within the first, second and third weight ports, respectively, and each of the first, second, and third weights comprises a tungsten weight.
