On June 9, 1963, the Houston Colt .45s host the first Sunday night game in major league history. Due to the extreme heat in Texas, the Colt .45s play the San Francisco Giants in the evening at Colt Stadium. Houston wins the game, 3-0, in front of a crowd of 17,437. The Colt .45s will move into the air-conditioned Houston Astrodome two years later.
