Abstract
A golf club includes a golf club head having a body defining an interior cavity. The body includes a sole, a crown and a skirt positioned around a periphery between the sole and crown. A face defines a forward portion of the club head and includes a striking surface width and a hosel defining a hosel bore. A channel and a recessed port are positioned in the sole. The channel extends substantially in a heel-to-toe direction. A sleeve is mounted on a tip end of the golf club shaft and is adapted to be inserted into the hosel bore. A fastener has a shaft portion extending through a passage and a head portion located in the recessed port. Selectively attaching the sleeve adjusts at least one of a loft angle and a lie angle of the club head.
