On 28 October 2026, MyGolfSpy published independent laboratory results for the 2026 TaylorMade TP5x golf ball. The ball itself was launched earlier in the year. Today's news is the quality-control evidence, not a new product release.
Ball Lab examined 36 balls from three boxes, produced at TaylorMade facilities in Taiwan and South Korea. It assigned TP5x a Quality Score of 93/100 and an A grade. None of the balls was classified as defective under the lab's criteria. This describes one tested sample, not every TP5x on sale.
Compression: the standout result
Average compression was 98, placing TP5x among the extra-firm tour balls. Individual readings ranged from 96.5 to 101.2, a spread of only 4.7 points. MyGolfSpy reports an average spread of 9.6 points in its comparison database. On this measure, TP5x ranked among the ten most consistent of 123 models tested.
Compression symmetry within individual balls was also strong: the median difference between measuring positions was 1.0 point, compared with 2.0 in the wider sample. This suggests consistent manufacturing. It does not, however, prove that every shot will be straighter: strike, launch angle, spin and conditions remain decisive.
Why the diameter finding matters — and what it cannot establish
MyGolfSpy reports a median diameter of 1.6798 inches, with some readings below 1.680 inches. Under the USGA and R&A Equipment Rules, 1.680 inches is the minimum permissible golf-ball diameter. The gap between the published median and that figure is just 0.0002 inches, or about 0.005 mm.
That does not mean an official non-conformance finding has been issued. Ball Lab performs its own independent quality measurements; the governing bodies use a separate formal testing process, including a ring gauge. It would be misleading to call TP5x a banned or non-conforming model on this evidence alone. Weight results raised no comparable issue: all 36 balls were below the permitted maximum, averaging 1.6044 ounces.
The engineering behind the 2026 ball
TaylorMade specifies a five-layer construction and cast-urethane cover with revised mantle materials. The manufacturer's Microcoating finishing process is designed to spread paint more evenly across the dimples, reducing tiny surface variations that can influence airflow. This is a documented design intention, not independent proof that every golfer will gain distance.
What players should conclude
The test provides useful evidence of compression consistency in this 36-ball batch, while reminding golfers to examine individual measurements rather than the overall grade alone. Fit still depends on driver and wedge spin, flight, feel during putting and actual on-course testing. Manufacturing consistency and playing performance are related, but different, questions.
