Although Easter was good enough to be a professional player, there was no Negro league franchise in St. Louis. So, in 1937 Easter joined the top team in the area, a semipro outfit called the St. Louis Titanium Giants. The team was made up of African-Americans employed by the National Lead Company. Players would work their factory jobs during the week, often with time off to practice, then play baseball for the company on weekends. Easter earned twenty dollars ($20) per week plus another ten to twenty on the weekends playing baseball. Luke Easter was a very large man, standing in height and weighing around . A left-handed hitting first baseman, he was known for towering home runs. During his five years with the Giants, they fielded a very competitive team. Also featuring Sam Jethroe, they went 6–0 in exhibitions against teams from the Negro American League in 1940.
