Ritger grew up in
River Falls, Wisconsin. He joined the PBA Tour in 1964, and won his first two PBA titles in successive weeks in
1966. He won his 20th and final PBA title in
1979. The 20 titles put him in a 14th-place tie with
Wayne Webb,
Amleto Monacelli and
Tommy Jones on the all-time list. He won multiple titles in five different seasons on tour, including three titles each in the
1969,
1973 and
1974 seasons. Ritger also won two titles in the Classic Division at the National USBC Championships, in Team (1967) and All-Events (1977). A gentleman on the lanes and off, Ritger won the PBA's Steve Nagy Sportsmanship award on two occasions. His status among the all-time greats was solidified with his election to the PBA Hall of Fame in 1978. Ritger's best chance at a major title came in 1970, when he made the televised final of the
Tournament of Champions and shot 268 in the final match. But he was on the wrong end of 26-time titlist
Don Johnson's legendary 299 game. He also finished runner-up in the 1972
PBA National Championship and 1979 Tournament of Champions.
