Through support of the Graduate Student Association (GSA), the softball diamonds are open from May until the end of November. Home to the GSA Softball League, Phoenix Cup tournament and Intramural games, the fields are also available for community group rentals. The John Harvey Field (Diamond 1), Jim Greenlee Field (Diamond 2) and Mary Keyes Field (Diamond 3) are all named after supporters who helped to bring the diamonds to fruition on the lower end of campus. Members of the GSA and Facility Services help maintain the diamonds to ensure the best possible playing conditions.
