April 10, 1962
Under the leadership of Judge Roy Hofheinz, Houston was awarded a National League expansion franchise in 1960 and began plans to build two stadiums: the futuristic Harris County Domed Stadium and a temporary stadium to begin operations in 1962. With the arrival of 1962, ground had been broken on the domed stadium, and the construction of the temporary ballpark (soon to be called Colt Stadium) was entering its final stages in preparation for Houston's first Major League team, the Colt .45s.
With an expansion roster of young players, the Colt .45s began their first Spring Training against the Los Angeles Angels in the franchise's first exhibition game on March 10. Exactly one month later on April 10, the Colt .45s opened the new Colt Stadium with elaborate pregame festivities, including a parade through downtown. After a first-pitch ceremony including Harris County Judge Bill Elliot, Congressman Bob Casey and Mayor Lewis Cutrer, the Colt .45s officially welcomed Major League Baseball to Houston with an 11-2 win over the Chicago Cubs in front of a crowd of 25,271. In the words of legendary journalist Mickey Herskowitz, the arrival of Major League Baseball in Houston was a "lifetime-changing experience."
The Houston Colt .45s organization quickly earned a reputation of being one of the most colorful franchises in all of Major League Baseball. With female ushers dubbed "triggerettes" and flamingo red, burnt orange and chartreuse seating colors, Colt Stadium became unmistakable among baseball fans. Excitement surrounded the city of Houston as fans eagerly anticipated the construction of the futuristic domed stadium and the continued success of the Houston's hometown team.
