Like many rookies in the major leagues, Ben Petrick believed that he was going to have his dream career. However, Parkinson's disease interrupted his dream. While he played in 240 major league games after he was diagnosed with Parkinson's at age 22, Petrick had to retire from baseball in 2004. Since then, he's written Forty Thousand to One, which is a memoir that discusses his experiences in the MLB with Parkinson's disease. Petrick also mentioned in an interview with ESPN, that his father was diagnosed with Parkinson's disease, but still has a positive attitude.
