In 59 Major League seasons on the air, Hamilton spent 28 of them in Houston before retiring in 2012.
Before his Astros broadcasting career began in 1985, Hamilton had previously served as a radio and television announcer for the St. Louis Browns, St. Louis Cardinals, Chicago Cubs, Chicago White Sox, Atlanta Braves and Pittsburgh Pirates.
Hamilton called more than 4,000 spring training, regular season and playoff games throughout his time in Major League Baseball.
Behind Los Angeles Dodgers announcer Vin Scully, Hamilton's 59-year broadcasting career is the second longest in league history.
A recipient of the Baseball Hall of Fame's Ford C. Frick Award in 1992, Hamilton is survived by his son, Mark.
