Z-Star Diamond
The current-generation Z-Star Diamond (2025 refresh, the ball J.J. Spaun played to win the 2025 U.S. Open), a 3-piece urethane ball with FastLayer DG Core 2.0 (soft center, firm outside), delivering the highest iron, driver, and greenside spin in the Z-Star lineup — a spin-first tour ball for skilled players.
What do these specs mean?
Compression
How soft the ball feels. Lower numbers (70–80) compress easier and help slower swings get distance. Higher (90+) rewards faster swings.
Cover
Surlyn is tough and cheap — great for distance and durability. Urethane is softer and grips wedges for more spin around the green.
Layers
2-piece: simple, long, straight. 3-piece and 4-piece add layers for more feel and spin control on approach shots.
Trajectory
How high the ball flies. Low = flatter flight with more roll. High = peaks up and lands soft. Mid = balanced.
Spin
Low spin = straighter shots, less curve, more roll. High spin = more control and stopping power on the green (but also magnifies slices/hooks).
Tier
Price bucket. Value = budget-friendly distance balls. Mid = solid all-around. Premium = tour-level spin and feel, costs more per dozen.
Best For
Try a sleeve first — ~$5 for 3 balls before committing to a dozen.

Who It’s For
The Srixon Z-Star Diamond is built for faster swing speeds (105 mph and above). It suits golfers who prioritize high swing speed, tour players, iron control. In the Srixon lineup, the Z-Star Diamond sits softer than the Srixon Marathon.
Feel
With a compression of 93 and a urethane cover, feel is firm and explosive — rewards fast swings with maximum energy transfer and a click at impact.
Spin Profile
Expect the highest driver spin in the Z-Star family — useful if you need the tee shot to hold its line, costly if your drives already balloon. Around the green, the cover gives you tour-level greenside spin and one-hop-stop performance on full wedges.
Trajectory & Construction
A mid-flight window — versatile across course conditions. The 3-piece construction uses a three-piece design — one mantle layer manages driver spin while the cover handles wedge grip. Works best in warmer conditions.
Price & Value
At $54.99 per dozen, this is a full-price tour ball. Expect the construction, cover, and performance to match.
Buy it if
- You swing 105+ mph and you want maximum spin and stopping power on approach shots.
- Greenside spin and stopping power matter more than durability.
Skip it if
- Your swing speed is under 95 mph — you won’t compress it enough to get the intended distance.
- You’re playing below 50°F — consider a softer-feeling ball in the cold.
