In 1978, Sager joined KMBC-Channel 9 in Kansas City, Missouri, where he broadcast Kansas City Royals spring training games and Kansas City Chiefs preseason games during the 1970s. Sager would remain at the station until 1981. The young reporter was later remembered by Major League Baseball hall of famer George Brett from an encounter at spring training as a "tireless worker" who would set up and focus the camera before conducting his own interview, essentially becoming a "one-man crew".
