Former Chiefs' player Brad Unger leads Waubonsee's program

Brad Unger, Head Coach

The 2017 season will be Bradley Unger’s third as head coach of the Waubonsee baseball program. He looks to follow up a fantastic 2016 season which saw his Chiefs win 37 games, advance to the NJCAA Division III World Series in North Carolina, and finish the season seventh in the nation. Subsequently he was named the Region IV Division III and NJCAA District B Coach of the Year. Under his direction the last two years the Chiefs have had 13 players earn All-Illinois Skyway Collegiate Conference (ISCC) honors and seven All-Region status, while designated hitter Klay Nafziger was an NJCAA Third Team All-American in 2016.

Coach Unger is the Assistant Regional Director for the Great Lakes Region with USA Baseball in their NTIS (National Team Identification Series) program. Unger is also part of Caliendo International Sports, where he coaches 15U-17U teams on International trips to Italy, Dominican Republic and Cuba. In addition, Unger is a Regional Instructor and Director of Travel baseball with the NPA (National Pitching Association) Chicago-group, and has worked for the prestigious Perfect Game scouting agency (1999-2001) leading their Davenport (IA) team in the Area Code Prospect Games.  

Unger coached 16 seasons in the Aurora American Legion League, directing his teams to over 200 wins and a league title in 2011. He enters his 19th season on the league’s Board of Directors as the League Director and Director of Fundraising, where he is tasked with collaborating on the league's annual budget, fundraising opportunities, and maintains the league’s website. He began coaching in 1998, leading Trinity Lutheran Jr. High School in Cedar Rapids, Iowa to its first winning season (16-11) in school history. Unger also helped found the Joliet Area Colt Conference in 2000 and was the league's commissioner until 2008. Unger guided Elmhurst College’s Winter Instructional Baseball Camps for 8 to 14 year olds from 2002 through 2006. Before taking over at Waubonsee Unger was the head varsity baseball coach at Hinckley-Big Rock High School for three season, guiding the Royals to the Little Ten Conference title (2013) and the Regional Championship games in 2013 and 2014.

A Plainfield Central High School graduate, Unger played his freshman season at Mt. Mercy University in Cedar Rapids, Iowa, where he earned the team’s 1999 Top Newcomer of the Year Award. An injury forced him to red-shirt the following season before he transferred to Waubonsee for his sophomore year to play for Hall of Fame Coach Dave Randall. In 2001 Unger was the Chiefs’ starting catcher, earning All-Skyway Conference, and All-Region honors that spring before representing Waubonsee in the NJCAA Region IV All-Star Game. The following summer Unger competed for International Athlete’s Team USA squad that traveled to Italy to play against professional teams in the Italian Baseball League (IBL). Unger then moved on to Elmhurst College and was the Bluejays’ team captain the next two years. His senior year he was selected to the All-CCIW First Team, was tabbed an NCAA Division III Second Team All-American, and was named Elmhurst College’s Male Athlete of The Year. Unger then went on to play professionally in the IBL with the San Marino Baseball Club in San Marino, Italy in 2003.

Unger earned his Associate’s degree from Waubonsee in 2001, his Bachelor's degree from Elmhurst College in 2003, double majoring in Business Administration and Marketing, and his Master's degree from Concordia University-Irvine in 2015, majoring in Coaching and Athletic Administration.
