Naperville Diamonds Announce Opening of “Diamond Mine”


More than 12,000 square foot training facility scheduled to open in September 


The Naperville Diamonds Softball Association (NDSA) is excited to announce the planned opening of its more than 12,000 square foot indoor training facility this September. Currently known as the “Diamond Mine,” the facility will serve as the home to the more than 325 girls fast pitch softball players who make up the current 28 teams within the Naperville Diamonds organization.

“The Naperville Diamonds board, specifically board member Bryan McNamara, has been working tirelessly over the past several years to find an indoor facility that we can truly call our home. We couldn’t be more excited for what this means to our players and our organization,” said Ron Kunkel, president, NDSA.

With a field area that covers 10,000 unobstructed feet, the Diamond Mine will be home to a full infield, as well as two 55’ x 12.5’ pitching and hitting tunnels, a reception area, restrooms and changing area for the teams. The playing surface will be comprised of artificial turf with several netting and fencing areas to make the facility as close to game-situation as possible.

The Diamond Mine is located just west of the intersection of 248th St. and Wolf’s Crossing Road. The NDSA will continue to provide updates on the progress of the facility as it nears its planned September opening. Events include a grand opening and advertising opportunities—including potential facility naming rights.
