Follow up from USBC in an email they sent me.
This is in reference to your e-mail of October 9, 2006.
Section 2a-3 ( Bowling Balls) on page 84 of the USBC Rule Book states,
"3. The surface of a ball must be free of all depressions or grooves of specific pattern, except for holes or indentations used for gripping the ball, identification letters and numbers, and incidental chipping or marring caused by wear. Any bowling ball used in certified competition must be approved and identifiable as a ball listed in the "Approved Bowling Balls" list located on the Specifications/Certifications page of bowl.com. Additionally, for identification purposes, each ball must have some form of serial number (this may be engraved or re-engraved by the bowler)."
The bowling ball you described is in violation of Section 2a-3 and therefore, should not be used in certified competition.
Question asked: If a bowler's bowling ball has a crack that is 8 inches long, 1/16 inch wide and 1/8 inch deep, is this ball legal to use in sanctioned league play? Would the rule in chapter 7 section 2a-3 apply? This not normal wear or a specific pattern.
I think that sould answer the question of whether or not I should have called for the ball's removal from sanctioned play.
