Zikes is the only man to win USBC Open Championships eagles in three successive years. He was a member of the winning teams in 1962 and 1963 and took the all-events and team all-events titles in 1964 in addition to two other championships. His 1963 win qualified him for the United States team in the 1963 FIQ World Tournament, thereby launching him on what was to become the most decorated nonprofessional, international career in bowling history. He collected no fewer than eight gold medals during two FIQ World and one American Zone championships. He was the all-events champion in both the 1963 World and 1964 American Zone. He was the first American bowler elected to the World Bowling Writers Hall of Fame. USBC Hall of Fame
