After appearing in 14 games for the Cardinals in 1970 as a rookie, Chlupsa made it back to the Big Leagues the following season, but for one game, and two innings of work.
Facing nine batters, Chlupsa allowed three hits and two earned runs while striking out one, giving him an “even” 9.00 earned run average for his efforts.
After starting the season in 1972 in the Cardinals Minor League system, he was traded over to the San Diego Padres, where he pitched for the Hawaii Islanders for the final season and a half of his career, never making it back to a Major League mound.
For his brief 15 game MLB career, he finished 0-2 with a 8.84 ERA over 18.1 innings pitched, all out of the bullpen.
