Sean Osborne
Baseball & Softball Hitting
Playing Experience:
Osborne grew up in Lemont and attended Providence Catholic High School in New Lenox, Illinois, about 40 miles outside of Chicago. In 2005, Osborne's collegiate baseball career began as a member of the Mesa Community College Thunderbirds. At Mesa, Osborne participated in the 2005 and 2006 Junior College World Series and performed at a high level with a .347 batting average in the Arizona Community College Athletic Conference, which is a wood bat league. His Alma Mater MCC and former coach Tony Cirelli won the 2014 World Series. In 2007, Osborne transferred to Indiana State University to finish his collegiate career. As a scholar athlete, his grit was on full display, as he set and still holds the school record for being hit by a pitch 40 times as a batter. The Sycamores recognized his leadership skills and went on to appoint Osborne as the team captain and recipient of the team leadership award his senior year. His former head coach Lindsay Meggs is now the head coach for the University of Washington in the PAC-12.
Coaching Experience:
After graduating from Indiana State with a Bachelor of Arts degree in Sports Management, Osborne returned to Illinois to join the coaching staff as a varsity assistant at Lemont High School. In 2010, Osborne was hired as the hitting and catching coach of the Benedictine University Eagles where he started his collegiate coaching career. The following year Osborne was the graduate assistant and head junior varsity coach for the Robert Morris University Eagles. After two successful baseball seasons at RMU, Osborne received his Master of Business Administration with concentrations in management and second concentration in human resources.
On September 1, 2011, Osborne was named the first head coach of the DuPage County Hounds, one of the members of the Midwest Collegiate League, a summer baseball league in Chicagoland. He is entering his seventh season with the team where he now takes on the role as the team's owner, after four years of being the club's head coach and two years as a General Manager.
While studying and coaching at Robert Morris, he also managed a youth travel team for three years. He quickly realized his passion was geared more toward youth sports which is why he started the DuPage Hounds youth travel organization as an umbrella and feeder program to the summer collegiate team. What started as the DuPage Hounds is now The 643 Baseball Club.

Baseball is a metaphor for life that will teach kids how to deal with failure and appreciate success as they go towards becoming a productive adult. I look forward to working with your son or daughter and helping them reach their full potential in baseball or softball.”
