Baseball Hall of Fame broadcaster Milo Hamilton, who had the memorable call on Henry Aaron's 715th home run, will retire as the radio voice of the Houston Astros after the 2012 season. "It's been a wonderful time and how great for me to finish up my broadcasting of games in Houston," Hamilton said Wednesday. This will be the 84-year-old Hamilton's 28th year with the Astros and 59th year overall calling Major League Baseball games. "He's been an icon broadcaster," new Astros owner Jim Crane said. "He's one of the greatest ever and has a history that's probably second to not many. He's meant a lot to the organization."
