Maddern attended the University of Arizona on a baseball scholarship and signed a contract with the Cubs" minor league affiliate Bisbee Bees, in the Arizona–Texas League.
His minor league career extended from 1940 through 1957. He threw and batted right-handed, stood 6 feet 1 inch (185 m) tall and weighed 185 pounds (84 kg). His career was interrupted by service from 1943 to 1945 in the United States Army during World World War II, when he served in the 76th Infantry Division.
Maddern served in France and participated in the Battle of the Bulge.
In 1946 Maddern was leading the Texas League in hitting with the Tulsa Oilers before being called up by the parent Cubs. The biggest moment in his career came the night of September 29, 1947, before a sellout crowd in Wrigley Field.
The Angels and the San Francisco Seals had finished in a dead heat for the PCL pennant and met in a one-game playoff. Maddern left baseball in 1957, returned to Bisbee and became an insurance agent.
He is buried in Evergreen Cemetery in Bisbee, Arizona.
He also was a stalwart in the postwar Pacific Coast League as a star for the Los Angeles Angels and a member of four other PCL clubs.
