The Knoxville Explosion Fast Pitch Softball Club is committed to developing player excellence on and off the field.  This is accomplished by selecting coaches who volunteer 100% of their time to teach the players the proper fundamentals of the game that include hitting, pitching, fielding and base running.  Each head coach will be a certified Double Goal Coach through the Nationally-recognized Positive Coaching Alliance Organization.  Key concepts are reinforced using state of the art training equipment, playing equipment, computer software and professional coaches that seek to identify and raise awareness of the player to correct flaws in their own fundamentals.  In addition, our players will be taught the proper way to conduct themselves on and off the field.  Knoxville Explosion Players are expected to honor and respect their coaches, parents, team mates, opponents and umpires.  Our players are also expected to do their very best in school courses and to place emphasis on their studies.  We recognize that our players are also students and without achieving the proper grades, our players will not be allowed to compete at the next level.  Our coaches are committed to teaching our players the rules of the game and more importantly, how to succeed and have fun!  A key component of this commitment is to teach our players the strategy and mental aspects of the game.  It is through this commitment to the fundamentals that our coaches and players will honor the game of fast pitch softball.
