HOUSTON -- Milo Hamilton, a Hall of Fame broadcaster who called Hank Aaron's historic 715th home run in 1974, has died.

The Houston Astros announced the death of their longtime play-by-play man on Thursday. He was 88. A cause of death was not immediately released.

Hamilton spent 60 years broadcasting MLB games, and was working for WSB Radio in Atlanta when Aaron became the all-time home run leader on April 8, 1974. Hamilton later said it was the highlight of his career.

Hamilton joined the Astros in 1985 and retired following the 2012 season. Hamilton since 2013 served as a guest radio commentator for select home games.

Astros president of business operations Reid Ryan says Hamilton was a ''true icon'' whose contributions to the game and beyond will be remembered always.
