Retired As Professional
Though Carter continued to bowl in the late 1960s and early 1970s, severe knee problems curtailed his effectiveness. His last professional tournament was at the 1972 Ebonite Open in Coral Gables, Florida. Carter officially retired in 1973.
At the end of his career, Carter had averaged 201 pins over his career. Known as the Babe Ruth of bowling, Carter had thirteen perfect games in tournaments and sanctioned events. Fellow PBA Hall of Fame member Dave Davis told Chuck Otterson of the Palm Beach Post, "Don had an impact on everybody in this sport. Don had that Arnold Palmer-type charisma. He and Dick Weber accomplished things using hard black rubber balls that have never been matched, even with today's lane conditions and urethane balls."
