Who it’s for: Golfers who want to play the same tour-level ball used by Keegan Bradley while celebrating his role as 2025 U.S. Ryder Cup captain.

What you should know: Keegan Bradley plays the Srixon Z-Star Diamond golf ball, so to honor his works and job as the 2025 U.S. Ryder Cup captain, Srixon created limited-edition version of the balls that pays homage to Bradley and new Boston roots.

The Deep Dive: When Keegan Bradley was named captain of the 2025 U.S. Ryder Cup team, it marked a new chapter in his career. To celebrate the moment, Srixon has created a Signature Series version of the Z-Star Diamond, the ball Bradley has trusted in competition since it was launched in 2022.

The commemorative version isn’t just about performance — it’s about symbolism. Each ball carries a red, white, and blue logo designed to reflect Bradley’s pride in American team golf. The packaging nods to his Boston roots with a detailed skyline illustration and Bradley’s likeness.

While the packaging and a logo on the ball are new, what hasn’t changed are the traits that make the Z-Star Diamond appealing to elite players like Bradley. With a compression rating of 100, the Diamond delivers a firmer feel than the standard Z-Star and produces the highest iron spin in the three-ball family. It blends the control and greenside spin of the Z-Star with the added distance and trajectory of the Z-Star XV, creating a ball that rewards aggressive iron play while still offering precision on short shots.

The ball’s SpinSkin+ coating has been reformulated to provide more durability while enhancing friction on wedge shots, which helps Bradley and everyday golfers alike generate spin and stop shots around the green. The FastLayer DG core, soft in the center but progressively firmer toward the perimeter, is designed to boost ball speed and maintain feel. For golfers seeking a balance of spin, distance, and stopping power, the Keegan Bradley Signature Series Z-Star Diamond offers the same performance Bradley relies on—just dressed in Ryder Cup colors.
