Kane County had previously been affiliated with the Cubs.
"We are extremely excited about our new relationship with the Arizona Diamondbacks," Cougars owner Dr. Bob Froehlich said in a statement. "Among many positives that we took from our recent meeting with members of Arizona's front office staff were these: their player development philosophy, their commitment to be passionately involved in the community and the feeling that beginning today, both the Cougars and Diamondbacks organizations can work in harmony with each other as a true partnership."
The Kane County organization announced recently a number of planned improvements for its ballpark -- Fifth Third Bank Ballpark -- including a new batting cage and an expanded weight and video room.
"We are thrilled and honored with our new partnership in Kane County," D-backs president/CEO Derrick Hall said in a statement. "It is important for us to align ourselves with affiliates who possess similar philosophies and values as us. The Kane County Cougars Baseball Club is an ideal fit, as they are committed to their fans, to winning, and most importantly, their community. This new home for us will provide our young players with a safe, welcoming, and enthusiastic setting."
