Erik Dial

Varsity Head Coach

Coach Dial joins the Mendham Minutemen after 3 years of being the Head Coach at Union Catholic High School.  In his first year, Dial led UC to a 10-11 record, an improvement from an 8-16 record the year before along with earning their first county win since 2016 with a 10-0 shut out over Dayton.  Under his leadership at UC, 9 players went on to play college baseball.  


Prior to Union Catholic, Dial was the pitching coach at Ridge High School from 2006-2018 where he was a part of the Red Devil's improbable 2011 Somerset County Championship run.  During that time, Dial provided guidance and instruction that helped numerous pitchers go on to play college baseball, most notably JB Kole, who was drafted in the 8th round of the 2014 MLB Amateur Draft.  


As far as his playing career, Dial played football at Hofstra University for two years before transferring to Rutgers to play baseball - his true favorite sport.  Dial pitched for Rutgers for two years before his career ended with an arm injury in the fall of 2004.  Dial graduated from Ridge High School in 2000 after a stellar career as an All-State athlete in football, basketball and baseball.  He was inducted into the Ridge High School Hall of Fame in 2011.  


Coach Dial currently lives in Lebanon, NJ with his wife, Ally and two sons, Todd and Brendan.  He looks forward to continuing the rich history of Mendham Baseball and developing long lasting relationships with the Mendham Baseball players and their families.
