A simple marker can be found in Worcester on the former site of the Worcester Agricultural Fairgrounds, which reads:
"On June 12, 1880, the first perfect game in professional baseball history was pitched on this site (the former Worcester Agricultural Fairgrounds) by J. Lee Richmond of Worcester against Cleveland in a National League game."
