Frederick Charles "Fritz" Maisel (December 23, 1889 – April 22, 1967) was a professional baseball player who played third base in the Major Leagues from 1913 to 1918, and was later a minor league player and manager and a major league scout. In his Major League career, he played for the New York Yankees and St. Louis Browns. Because of his speed on the basepaths, he was known as "Catonsville Flash" or just "Flash" by his fans. In 1914, he led the American League with 74 stolen bases, and was only caught stealing 17 times that year, an 81 percent success rate.
