From a New York Times obit by Richard Sandomir headlined “Mike Shannon, a St. Louis Cardinal for Life, Dies at 83”:

Mike Shannon, who played in three World Series with the St. Louis Cardinals and then became a favorite of the team’s fans as one of its radio broadcasters for 50 seasons, died on Saturday.

Shannon was one of the few announcers in baseball history to spend 50 years or more with one team. His longevity was among the things that endeared him to listeners, along with his exuberance and his passion for seeing the Cardinals win.
