^Schwartz, Paul. "Bob Potts dead at 73; Fair Lawn native heart and soul of Met League.", The Record (Bergen County), October 24, 2007. "In 1954, as a 17-year-old Fair Lawn High School student, Potts established the Fair Lawn Athletic Club baseball team to give himself and his friends a chance to play summer baseball. The team soon became the Paterson and later the Clifton Phillies, which was one of the most successful teams of its kind in the country until it folded in 1999. Among the first players on the Phillies was Potts' high school teammate, Ron Perranoski, who later starred as a relief pitcher on several Los Angeles Dodgers world championship teams."
