Joliet, IL —The Joliet Slammers are pleased to announce Aaron Nieckula as the new field manager of the team.  Nieckula joins the Slammers after a seventeen year coaching career with the Oakland Athletics, where he began in 2004 as the hitting coach of the Kane County Cougars.  He quickly moved up to become Manager of the Cougars, before later managing the Burlington Bees, Stockton Ports, Midland Rockhounds, and Vermont Lake Monsters - all in the A’s farm system.  Since 2015, in addition to his managerial assignments he also served as the A’s Arizona Field Coordinator, where he mentored coaches and coordinated player development during the baseball offseason.

Nieckula graduated from Fenwick High School in Oak Park before attending the University of Illinois, Urbana-Champaign.  He was drafted out of the U of I in the 22nd round by the A’s in 1998.  He spent 4 years playing in the A’s minor league system, and 1 year playing in the San Francisco Giants minor leagues before becoming a coach.  He graduated from Lewis University with a Masters Degree in Organizational Leadership in 2015.

“As the Frontier League and the Slammers begin our partnership with Major League Baseball we are very excited to have someone with Aaron’s experience and record in affiliated baseball join us to lead our team on the field in 2021.  He is a proven winner, and a very strong developer of talent, and all of us are pleased to add him to our Slammers family,” said Slammers majority owner Nick Semaca.

"I'd like to thank the entire Slammers leadership team for this opportunity, and I am eager to begin building, in collaboration with Nick, Heather, and John, a culture and standard of excellence that is heavily focused on player development while maintaining a championship mindset. I have always admired the Slammers organization and am now affiliated with one of the premier MLB Partner League teams in the country," said Nieckula.

Aaron currently resides in Yorkville with his wife and three daughters.
