USBC has revoked approval of the Storm Spectre bowling ball and removed it from the list of balls approved for USBC competition effective March 14, 2022. The revocation comes after USBC determined through its spot-checking procedures that a significant percentage do not meet the minimum 73D hardness specification in the USBC Equipment Specifications and Certifications Manual.
