Dennis Biddle is a former Negro League Professional Baseball Player who played for the Chicago American Giants. Biddle is most known for making his debut in 1953 as the Giants' pitcher when he was only 17 years old. He is also known as "the man who beat the man who beat the man". He is on record as being the youngest player ever to play in a Negro baseball league game. Sadly, Biddle injured his ankle the next year which ultimately ended his playing career. In 1996, Biddle founded Yesterday's Negro League Baseball Players, LLC and currently serves as the president. He travels around the country to colleges, schools, universities, and community organizations, giving educational insight about the hidden truth of the Negro Baseball League. He also aims to raise awareness of the injustice the Negro Baseball Players face, from past to present, and how to be an active voice for positive and effective change for "America's best past time" sport.
