Mouth McGarry is the manager of the Hoboken Zephyrs professional baseball team. They are perennial losers and are already so far back in the standings that they have no chance of winning the pennant. McGarry is approached by Dr. Stillman who has a solution for him, Casey, who seems to be an ideal pitcher, the best McGarry has ever seen. The catch is that Casey is a robot. McGarry is eager to win and decides to use Casey without telling anyone. When his ruse is discovered, Dr. Stillman agrees to give Casey a heart to make him more human. The results aren't quite what McGarry had hoped for.
