Ahead of The Match against Bryson DeChambeau, Brooks Koepka switched into a new ball from Srixon, called the Z-Star Diamond. According to Srixon, the Z-Star Diamond combines design properties from its two current tour ball offerings: the Z-Star and Z-Star XV. The Z-Star Diamond ball has a new FastLayer Core that’s soft in the center and gets progressively firmer toward the edge to increase ball speed. Srixon also made the Z-Star Diamond produce more spin on mid and long-iron shots to help with stopping power on the greens.
