Ullrich's career took place during World War II. With many baseball stars leaving to serve the United States, it was questioned whether Major League Baseball would continue during this period. Franklin D. Roosevelt declared that it would, and therefore teams needed players to fill the spots of players that had left. Ullrich was one of the many that played Major League Baseball during this period. Unfortunately for Ullrich, when the war ended players returned to their teams. Like many others, Ullrich found himself out of the Major Leagues.
