The stadium was the site of the first World Series game between the modern American and National Leagues in 1903, and also saw the first perfect game in the modern era, thrown by Cy Young on May 5, 1904. The playing field was built on a former circus lot and was extremely large by modern standards- to center field, later expanded to in 1908. It had many quirks not seen in modern baseball stadiums, including patches of sand in the outfield where grass would not grow, and a tool shed in deep center field that was in play.
