TROSKY USA – The Leader in Player Development!


A Note from Coach Trosky:

Nearly 30 years ago I started running skills development baseball camps for high school and youth players. I truly love the developmental side of the game, and early on in my life, it became my passion. After about 15 years of running training camps, numbers began to drop because kids would rather play travel ball and be seen by college coaches than go to a camp to learn about baseball fundamentals. At this transition time in the baseball culture, I adapted and moved the focus of my business from player development to travel ball, showcases, and college exposure. Within the change, over the past 20 years, I’ve enjoyed my occupation and I’m sincerely grateful for the many relationships I’ve built and for the extensive education that has taken place in my life from being surrounded by some of the best in the game. Within those years of growth and collaboration, I developed creative ways to bring player development (both mental and physical) into the showcase and travel ball world. Entering into the 2018 travel ball season, I am excited to offer a new Complete Player Development (CPD) model to all the Trosky Baseball teams.


CPD (Complete Player Development)

CPD takes players to another level! The mission is for every athlete to reach their personal ceiling both academically and athletically, transforming them both internally and externally. Coach Trosky has created the learning systems and models that will be used for player transformation through the Trosky Recruiting System / Trosky 5 Tool Development model / High-Intensity Trosky Boot-Camps / & the Trosky 6th Tool Mental Makeup – Character Development model.


The Trosky Player Development Model is Based on 3 Key Principles: 

  1. Intent: Specific goal setting in multiple areas (navigation goal cards with specific goal dates, target dates, and routines).
  2. Accountability: Regularly holding players accountable through coaches' reinforcement, player reinforcement, practices, gatherings, 6th Tool Nation weekly emails, text messages, social media, and Google Docs. 
  3. Culture: Developing a culture of excellence where players and coaches are on the same page encouraging each other to become the best they can be through 6th Tool Nation Concepts. 


The Trosky Player Development Model is Based on 5 Key Concepts: 

  1. Plain Vanilla: Identifying what really matters (the Main Thing) and being totally committed to it (the Main Thing) TMTKMTTMT.
  2. 3RP: Training Trosky players to be masters of 3RP; the ability to read, recognize, and react, within tenths of seconds, unconsciously, with precision. 
  3. The Graveyard: There’s a great disparity between what people set out to accomplish and what they actually accomplish. Our mission is that each of our players accomplishes their dreams and goals both academically and athletically.
  4. The 6th Tool: the 6th Tool, the mental makeup, and character of a player is the great separator. We make it a priority to develop the 6th Tool in each of our players.
  5. Intent / Accountability / Culture: Intent, accountability, and culture are the three pillars for our players to reach their fullest potential.



A few years ago, New Balance / Area Code Baseball hired me to run their National Camps, and recently I was hired by MLB to be the Director of Player Development (BTS / USA Baseball). The same model that I created for Area Code Baseball and MLB (BTS / USA Baseball) we’re implementing with our Trosky teams. This player development model that we’re offering our players is completely unique. It is a model that has not been established and accomplished before in travel baseball.

We’re very excited about what’s ahead for Trosky Baseball and for all the outstanding contributors and staff members that make Trosky Baseball a complete family.

We invite you to be a part of the Trosky family (the 6th Tool Nation) in the transformation of the lives of thousands of aspiring amateur baseball players across the country!


Thank you,

Nate Trosky
