Mizuno Pro X

Find the Right Golf Ball for Your Game

Use the MyGolfSpy Golf Ball Selector to compare 48 golf balls using data from our 2026 robot test. Filter by swing speed and see how each ball performs from driver to wedge to find the best fit for your game.

Compression is a measure of how much force is required to deform a golf ball. The higher the number, the firmer the ball. Consistency matters because a ball that compresses differently from shot to shot produces different results from shot to shot. Ball Lab measures every ball individually and tracks both the average and the spread across the sample.

The 2025 Mizuno Pro X averaged 103, in the extra-firm range of our database alongside the Titleist Pro V1x. Compression consistency graded at B- with a delta of 7.7 points and a spread running from 98.3 to 106.0. That delta beats the field average of 9.5 points so while the grade is B-, the raw number tells a better story than the letter might suggest relative to what we typically see at this compression level.

Ball Lab also measures compression symmetry which tracks how evenly compression is distributed across three points on each individual ball. Is each ball consistent within itself? The Mizuno Pro X averaged 2.0 points of deviation against a field average of 2.0, grading at C+, right at the field average. Some balls in the sample showed meaningful spread across the three measurement points which is what pulls this grade down and separates it from the stronger performers in the database.

For context, elite tour balls typically come in around 1.0 or below on compression symmetry. The Pro X is sitting at exactly the field midpoint; not a red flag but not a strength, either.

The charts below detail the compression measurements in our sample.

Weight consistency is another metric Ball Lab tracks. Even small differences across a dozen balls can translate to inconsistent ball flight. Ball Lab weighs every ball to four decimal places.

The 2025 Mizuno Pro X averaged 1.6015 ounces across 36 balls, in the light range of the database. Every ball cleared the USGA maximum of 1.6205 ounces with a range running from 1.5919 to 1.6115 and a standard deviation of 0.0043. That standard deviation is notably higher than what we see from the stronger performers in the database and it shows up in the chart. Box 3 showed the most spread, running lighter and less consistent than Boxes 1 and 2 which accounts for a meaningful portion of the overall drag on this metric.

Weight consistency grades out at C.

The charts below detail the weight measurements in our sample.

A ball that isn’t uniform in shape can move offline on the putting green or produce inconsistent flight in the air. Ball Lab measures each ball across multiple axes to get a true picture of its shape.

The 2025 Mizuno Pro X averaged 1.6822 inches, above the USGA minimum of 1.680, with a roundness deviation of 0.0011 inches. Every ball cleared the minimum. The pole-versus-seam data shows no consistent shape bias across the sample: balls split 14 thicker at the pole, four thicker at the seam and 18 within gauge noise which tells us there’s no lot-wide pattern to speak of. Box 1 was the least consistent of the three at an SD of 0.00088 while Boxes 2 and 3 ran tighter.

Diameter consistency graded out at B-.

In the 2026 MyGolfSpy Golf Ball Test, the Mizuno Pro X showed up in a few notable spots across the field.

At high swing speed off the driver, the Pro X was one of the longer balls in the test, finishing in the same group as the Pro V1x and Snell PR4. It was well above the test median for carry distance. That’s a strong result for a ball at this price point.

At mid swing speed, it earned a spot as a high-spin pick off the driver, finishing among the highest-spinning balls in that category alongside the Srixon Z-Star Diamond and Callaway Chrome Tour X. For golfers who need spin to hold greens and stop the ball, that’s a meaningful data point. It also landed a mid-speed pick for players prioritizing spin profile over raw distance.

The one area where the Pro X fell back was iron ball speed at high swing speed where it tracked near the bottom of the speed chart among firm balls. That’s consistent with what an X-firm compression profile tends to produce in robot testing. It’s a tradeoff that comes with the territory.

Taken together, the ball test data supports what the construction suggests: the Pro X is built for the faster, high-spin golfer who wants a firm, tour-level ball without paying a premium price.
