ABSTRACT:
A golf ball (20) having a plurality of standard dimples (33) and a plurality of undercut dimples (31) is disclosed herein. Each of the plurality of undercut dimples (31) has at least one undercut area portion (50) that extends into a portion of a concavity (55) of the undercut dimple (31). A covered region (70) defined by the undercut area portion (50) generates eddy currents during the flight of the golf ball (20) which creates greater turbulence at the surface (22) of the golf ball (20) allowing for greater distance.
