Ben Krentzman

Head Coach

Ben Krentzman was a 4-year letter winner as a member of Bucknell University’s Division 1 Baseball Team and graduated in 2003. His teams captured two Patriot League Championships and he advanced to the regional tournaments playing against University of Texas and University of Miami.

After his college playing days, he began his coaching career at Clearwater Florida High School in the role of hitting and outfield coach. He was instrumental in steering the 2005 team to district and conference championships. During his two-season tenure, he instructed five players that went on to play college baseball.

In 2007, Ben accepted a coaching position from Bucknell University handling hitting and outfield responsibilities. His 2008 team won the Patriot League Championship and beat a Florida State team led by Buster Posey for Bucknell’s first ever Regional Tournament Victory. During his coaching tenure, Krentzman instructed three different players to the Patriot League career home run record.

While coaching at Bucknell, Ben concurrently was approached and accepted the role of hitting coach for the Alexandria Aces, a summer team in the Cal Ripken Collegiate League. He instructed players from Virginia Tech, University of Virginia, University of Penn, Rutgers, and Yavapai.

From 2010 through 2012, Krentzman would go on to coach at Flager College and helped lead the team to its first ever Peach Belt Tournament appearance. He then accepted a position at Lehigh University as hitting coach and director of baseball operations. Beyond coaching, Ben recruited the Lehigh Freshmen class that would go on to win the Patriot League Championship.

With a goal of continuing his education, Krentzman accepted the role of hitting coach, outfield coach, and recruiting coordinator at Eastern University while also earning his Masters Degree in Organizational Leadership.

Ben is now putting down roots in the area with his wife and young daughter. Being out of baseball for a couple of years, he was intrigued and excited by the 2019 offer of head coach of the then Hornets 13U team. He accepted the position with much enthusiasm as he knows he brings a wealth of experience to a critical age of baseball development.

Head Coach Ben Krentzman delivers a unique perspective to the Hornets 17u team, having played, coached, and recruited at the college level. He knows firsthand the work, talent, and approach to playing baseball at a very high level and will impart this knowledge with the players he guides. This level of expertise is not often seen outside of high profile academy teams. Not having a son, relative, or family friends on the team gives him the unbiased latitude to teach all players equally and make decisions for the good of the team. His philosophy is one of positivity, love of the game, respect of your teammates, and working together for the greater good.

I hope to take my knowledge and success as a player and apply it the development of our players, especially our pitchers.

"Harley" Dave Sonn

Operations & Analytics

Harley was an outfielder into his high school years and he points back to his 13 to 15 year old travel squad where he really learned how to be part of a team. Both as a rookie who had to lug the team equipment to a senior member who set the example for the younger players, it's here where he learned to work within a group. He's carried these valuable lessons into his professional life and as an entrepreneur who has founded multiple companies, built teams of people, and created a variety of ventures, it's these inner workings and dynamics of a ball club that he still draws upon today. It's his goal that Hornet players walk away with the same value.


Sonn has over 15 years experience in coaching teen and youth baseball, both as a head coach and an assistant, leading teams to undefeated seasons. His approach to coaching is to teach and create success for all players versus simply managing the stars. He understands how to leverage the power of the lineup and the intangibles only learned by both playing and coaching the game. However, for Hornets Baseball he does not make any on-field, baseball decisions and serves in a supporting role assisting with practices and game day logistics.


Rather, his primary role for the Hornets Baseball program is to manage all operations from tournament scheduling, logistics, uniforms, and financial issues, to communications and off-field tasks. His goal is to provide the most organized, effective, stable, and communicative baseball program possible. An important focus of his is team culture. A team that believes it has the support of its coaches and teammates gains the confidence to perform at a higher level.
