When his playing days ended, he stayed around the game as a reporter, in later years writing newspaper columns on the Montreal Expos and Toronto Blue Jays.
In 1998, he was inducted into the Manitoba Baseball Hall of Fame Journalism/Broadcasting career: Robertson worked as a sports reporter and columnist at the Regina Leader-Post in the early 1960s and grew to love the Saskatchewan Roughriders CFL football team over his hometown Winnipeg Blue Bombers.
When the Roughriders were close to bankruptcy during a tragic 1979 season, Robertson flew in from Winnipeg (where he now worked for CBC Television) at his own expense to help out coach Ronnie Lancaster.
Taylor Field was full to capacity for that game and the efforts of Lancaster and Robertson managed to save the football team from certain extinction.
Around the same time in November 1979, in his regular back page column for Maclean's magazine, Robertson coined the term "Rider Pride" when he wrote about his experiences and his feeling that the Roughriders had the best fans in the CFL.
