The logo of the Houston Colt .45s baseball franchise, which entered the National League as an expansion franchise along with the New York Mets in 1962. The Colts flew somewhat under the radar as the Mets dominated the news as a laughing-stock franchise. Hall of Famer Joe Morgan started his career as a Colt. The team’s owner, Judge Roy Hofheinz, had the world’s first domed stadium built, The Astrodome , and the team moved into the dome in 1964, and was renamed the Astros.
