USBC UPDATES NATIONAL TOURNAMENT RULES IN RELATION TO PURPLE HAMMER

ARLINGTON, Texas - The United States Bowling Congress is aware of a claim that a portion of the Purple Hammer bowling balls manufactured at the Ebonite International plant in 2016 and 2017 may have been produced below USBC's minimum 72D hardness specification. The Hammer brand was purchased by Brunswick Bowling Products in 2019, and the Ebonite plant subsequently closed.

USBC conducted an investigation, interviewing more than a dozen individuals, including former Ebonite employees, in an attempt to validate the claim. Brunswick fully cooperated with the investigation.

USBC has confirmed a production change with the Purple Hammer took place in 2017 that resulted in the raising of the hardness of the ball from its original 2016 approval level just over 72D to about 74D. This production change was fully compliant with USBC equipment specification requirements.

During USBC's investigation, multiple former Ebonite employees, including ones with first-hand knowledge, told USBC they believe the production process in 2016 and 2017, prior to the production change, led to some Purple Hammers being unintentionally produced below 72D. No one interviewed by USBC provided evidence Purple Hammers were produced under 72D. No one interviewed by USBC provided evidence Ebonite knowingly distributed balls outside of specification.

The findings of USBC's investigation are inconclusive. However, the credible first-hand accounts describing the potential for an unknown number of Purple Hammer balls to be produced out of specification in 2016 and 2017 is concerning.

Therefore, effective immediately, USBC is instituting a tournament rule at all USBC national tournaments prohibiting Purple Hammers manufactured in 2016 and 2017 from being used in these competitions. The tournament rule reads:

Purple Hammer bowling balls manufactured during 2016 or 2017 (identified by serial numbers that start with either a "6" or "7") are prohibited for use.

USBC has shared this national tournament rule with Hammer's current owner, Brunswick, and has Brunswick's support. Brunswick will offer owners of 2016 or 2017 Purple Hammers the option to exchange their balls for a new Purple Hammer that can be used in all tournaments or a product of their choice. This can be done on-site at the 2022 USBC Open Championships or USBC Women's Championships, or by contacting Brunswick at: consumerproducts@brunswickbowling.com or 800-937-2695.

The Purple Hammer, including the 2016 and 2017 models, remain USBC approved. USBC's equipment specification manual allows for revocation of ball approval when balls at the time of manufacture demonstrate non-compliance to specification. USBC has no such evidence and is unable to locate enough blank balls from 2016 and 2017 to conduct conclusive testing.

Each USBC competition, whether tournament or league, has the option to adopt USBC's national tournament rule on the Purple Hammer or other rules related to equipment restrictions.

UPDATE 3/21/22

USBC REVOKES APPROVAL OF 2016 AND 2017 PURPLE HAMMER BALLS

ARLINGTON, Texas - The United States Bowling Congress has revoked approval of Purple Hammer bowling balls manufactured in 2016 and 2017. These model years are removed from the list of balls approved for USBC competition effective March 21, 2022. These model years of the Purple Hammer may no longer be used in any USBC-certified competition, including all USBC leagues and tournaments.

Purple Hammer bowling balls manufactured during 2016 or 2017 are identified by serial numbers that start with either a "6" or "7."

USBC investigated allegations that a portion of the Purple Hammer bowling balls manufactured at the Ebonite International plant in 2016 and 2017 were produced below USBC's minimum hardness specification at that time of 72D. The Hammer brand was purchased by Brunswick Bowling Products in 2019, and the Ebonite plant subsequently closed.

After a former Ebonite employee made public comments on this matter, USBC conducted an investigation. USBC interviewed more than a dozen individuals, including former Ebonite employees, in an attempt to validate the claim. Brunswick fully cooperated with the investigation. USBC announced its initial findings on March 7, 2022, that included a national tournament rule prohibiting use of the 2016 and 2017 Purple Hammer.

Following that announcement, additional information was provided to USBC causing the investigation to be reopened. Four additional interviews were conducted.

USBC has the authority to revoke approval of a bowling ball if it determines production balls do not comply with current specifications outlined in the USBC Equipment Specifications and Certifications Manual. Based upon all the information gathered in the investigation, USBC now has made this determination about the 2016 and 2017 Purple Hammers.

During USBC's investigation, former Ebonite employees, including ones with first-hand knowledge, provided detailed statements to USBC outlining how processes in 2016 and 2017 led to some Purple Hammers being produced and sent to the field below 72D. Multiple former Ebonite employees confirm that a production change took place in 2017 to raise the hardness of Purple Hammers produced in 2018 and 2019.

USBC has shared its determination with Brunswick and has Brunswick's support. Brunswick will continue to offer owners of 2016 or 2017 Purple Hammers the option to exchange their balls for a new Purple Hammer or a product of their choice. This can be done on-site at the 2022 USBC Open Championships or USBC Women's Championships, by claiming a replacement ball at www.hammerbowling.com/Purple, or by contacting Brunswick at consumerproducts@brunswickbowling.com or 800-937-2695.

Unapproved bowling balls may not be used in USBC-certified competition. Bowlers who used 2016 and 2017 Purple Hammers in competition before March 21, 2022, with no prior knowledge of their balls being out of specification, would not be subject to forfeiture under USBC rules.
