Sam Lynn Ballpark (also known as "Historic" Sam Lynn Ballpark) was a baseball venue in Bakersfield, California and was the oldest ballpark of the Class-A Advanced California League. It was built in 1941 for the Bakersfield Badgers who began that season as a charter member of the California League. The current tenant is called the Bakersfield Train Robbers, who play in the Pecos League and are not affiliated with any team in Major or Minor League Baseball.
