Colt Stadium was the first home of Major League Baseball in Houston. Upon being awarded a National League franchise in 1960, Houston began construction on the Astrodome, but it was soon realized that the stadium would not be ready in time for the 1962 season. With this in mind, team officials decided to construct the first-ever temporary stadium in Major League history and declared that it would seat more fans than at least six other stadiums in Major League cities. Construction on Colt Stadium began on Aug. 9, 1961, just northwest of the future Astrodome site.
The Colt .45s played their first-ever regular season game on April 10, 1962, putting on a show for their fans and routing the Chicago Cubs, 11-2. Fans cheered as Bob Aspromonte scored the first run and Roman Mejias hit the first home run in team history. Houston celebrated this momentous occasion and, while the Colt. 45s did not continue these winning ways in 1962, professional baseball was the talk of the town as fans flocked to the new stadium. The Colt .45s sold out the stadium for the first time during a June 10 doubleheader. The temperatures were so sweltering that day that the team received permission to play the first Sunday night games in Major League history.
Although Colt Stadium would soon be pushed into the shadows of the Astrodome, it still had its share of unforgettable quirks. One of the most obvious of these quirks lied in the stadium seats that had colors ranging from flamingo red, burnt orange and chartreuse, to turquoise. Also unique to Colt Stadium, female ushers were dubbed "Triggerettes," and parking attendants wore orange Stetson hats with blue neckerchiefs and directed cars into sections named "Wyatt Earp Territory," "Cheyenne Bodie Territory," and "Matt Dillon Territory." On the field, the ballpark dimensions were some of the biggest in baseball, with the field measuring 420 feet to center, 395 feet to the power alleys and 360 feet down the lines in left and right. These dimensions would aid in multiple Colt .45s no-hitters by Don Nottebart and Ken Johnson.
The Colt .45s ended their short stint at Colt Stadium on Sept. 27, 1964, when they played their final home game against the Los Angeles Dodgers. Less than one week later, Judge Roy Hofheinz announced the end of the "Colt .45s" name as plans for a new team were announced. Plans to make Colt Stadium a Spring Training site or a high school field never materialized, and the stadium was eventually dismantled in 1970 and shipped to Torreon, Mexico, where its parts were reconstructed and became the new home of the Cotton Pickers. A structure that brought a new era of baseball to Houston, Colt Stadium, is still the only stadium ever to be sent to the Minors.
