Locally, KTRH-AM and WMVP were the primary carriers for the World Series in the Houston and Chicago markets. For KTRH long time Astros voice Milo Hamilton provided play-by-play while John Rooney called the games for the White Sox. Game 4 was Rooney's last call after 17 years as the radio voice of the White Sox, as he left to take the same position with the St. Louis Cardinals. The Cardinals proceeded to win the 2006 World Series, making Rooney the first home announcer to call back-to-back World Series wins for two teams. That the teams were in two leagues makes the feat even more unusual.
