Darrel Grissom

Position: Head Coach/ Director of Baseball Operations
Hometown: Hamilton, Ohio
Alma Mater : Talawanda High School
Experience: 23rd Season
Graduated: 1974

 

 

Darrel Grissom is the current Head Coach and Director of Baseball Operations for the Miami University Hamilton Harriers. Coach Grissom is entering his 23rd season leading the Harriers. Under Grissom's guidance, MUH has won 17 of 19 conference championships, 17 of 19 conference tournaments and has averaged more than 30 wins a year in the ORCC.  Beginning in the 2022 season, Grissom led the Harriers into a new association:  The United States Collegiate Athletic Association (USCAA).  In their first year, the Harriers finished as the national runner-up, compiling a 25-20 record.  Coach Grissom was named National Coach of the Year in his first year in the association.  During Coach Grissom's coaching career he has compiled a record of 683 wins and 356 losses and one tie over 22 full seasons as Head Coach, making the Harriers one of the most dominant baseball teams in the state of Ohio.

In 2009, Grissom set out on a new baseball venture, co-founding the Hamilton Joes of the Great Lakes Summer Collegiate League (GLSCL).  The Great Lakes League is one of only 10 summer collegiate wood bat leagues in the US sanctioned by the National Alliance of Collegiate Summer Baseball (NACSB).  It is funded in part by Major League Baseball and consists of MLB draft prospects from around the nation.  As the inaugural Head Coach of the Joes, Darrel had the opportunity of working with elite athletes from all levels of college baseball.  In 2010, the Joes completed their second season by winning the GLSCL championship and ranking 12th overall nationally.  In 2013, Grissom took on a new role with Joes as the organization's General Manager.  He has since also taken over the role of President of the GLSCL.  The Joes are currently coached by former Harrier Tyler Thamann.

The Joes have since won 3 additional GLSCL championships: 2016, 2021 and 2022.  The back-to-back 2021 and 2022 teams were coached by current Harrier coaches Tyler Thamann and Ryan Finnerty.  Since 2009, the Hamilton Joes have had 55 players sign professional contracts.  Five alumni have made it to the Major Leagues (Brent Suter, Ryan Rua, Matt Marksberry, Andy Young, and Hunter Owen).

Off the field, Darrel is married to his loving wife, Jill, of 48 years and has three children; Amy Baker, Niki Hudson, and Adam Grissom.  Darrel also has eight lovely grandchildren that love to call him "Pawpaw".
