From the '70 Game Program
Turns out Kittle did NOT put himself into a game for Oklahoma City in 1970, but ten years later, would pitch again. On August 27, 1980, according to BaseballLibrary.com, "Pitcher and coach Hub Kittle becomes the oldest man to play in an organized baseball game when he starts for Springfield (American Association) against Iowa at the age of 63 years and six months. Kittle retires the side in the first inning, then tosses one pitch to retire a batter in the 2nd frame before exiting."
