Worcester Agricultural Fairgrounds was a 20-acre site in Worcester, Massachusetts in the 19th century. It was bounded by Highland Street, Sever Street, Cedar Street or William Street, and Agricultural Street. The grounds were just east of the large public park called Elm Park. Today, the former fairgrounds property contains a grid of streets, and many homes and businesses, including Becker College. The Fairgrounds was home to an agricultural fair and to a horse trottingrace track, usually called the Driving Park. "Driving" was a commonly used synonym for trotting, long before the term "driving" came to be associated primarily with the not-yet-invented automobile. The grounds are known today mainly as the home ballpark of the National League's Worcester Worcesters from 1880-82. On June 12, 1880, Worcester pitcher Lee Richmond threw the first perfect game in major league history. There is a granite post commemorating the perfect game on the Becker College campus. The park was also the site of the first, true major league double-header. For the price of a single game, Worcester fans saw two games against the Providence Grays on September 25, 1882. The last game for the local major league club was played on September 29, 1882, with Troy defeating Worcester, 10–7, after which the park was torn down. But it was not the last big-league game in Worcester; five years later, on August 17, 1887, a new Driving Park hosted a National League game between Washington and Boston. "Honest" John Gaffney, later the "King of Umpires," who had been hired the year before as Washington's manager, had the game transferred to Worcester, where he had grown up. Prior to Worcester acquiring a National League franchise, the Driving Park hosted other big-league games, including a National Association tilt on October 30, 1874, between Boston and the Hartford Dark Blues; Hartford won, 17–11, in front of a crowd of 500. Previously, an exhibition game between the NA pennant winner Boston Red Stockings and runner-up Philadelphia Whites was played on October 30, 1873 after the end of the championship season. Boston prevailed 15–9 before a crowd of 2,000.
