He served in the US Air Force in Germany, at Wiesbaden Air Base, in the early ‘60s, pitching successfully for the base team, the Wiesbaden Flyers.
In the minors, Purdin threw a perfect game against Lexington in 1964. The game went seven innings, on the backend of a doubleheader. During warmups, he pegged his usual starting catcher, Butch Johnson, in the eye. Jim Connor came in from third base to replace him for the night, and Ed Knipple moved to third. Purdin struck out 11 batters in the perfect outing, with Knipple driving in the only run of the game.[3]
