The team's jerseys will also feature a patch honoring Hamilton's “distinguished career.”
Hamilton, who died Thursday at age 88, spent 28 of his 59 Major League seasons on the air with 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.
A recipient of the Baseball Hall of Fame's Ford C. Frick Award in 1992, Hamilton is survived by his son, Mark.
