Coached by people who know the game.

A staff built around professional scouting and player development.

Our story

South Florida has always produced elite baseball talent. We're here to make sure the next generation gets the development it deserves, on the field and off it.

For too long, talented players haven't received the instruction and training they need to reach their potential. TNXL Miami was built to change that, with professional-level player development, modern technology and data, and a staff that coaches every athlete from their own plan.

Better players. Better young men. That's the goal, and we believe the impact will reach an entire community.

I started TNXL Miami to use my experience in baseball to bring a professional level of player development to South Florida, to prepare players physically, mentally and emotionally to compete at the highest levels of the game, and to provide them with the skills needed to succeed in life beyond the baseball field.
