Five minutes. No commitment.
A real call with you and your parents about your goals.
One plan, built around you, adjusted as you grow.
Most programs are coached from behind a desk. One of your coaches is starting ACC Friday nights right now. The other earned his way from D3 to Clemson. Both know the road, because they're on it.
Baseball is more than mechanics. We guide athletes through the mental and emotional side of the game and build the character that leads to success.
Progress comes from daily habits, not occasional bursts. We build routines that compound into long-term results.
Technical ability means nothing without the confidence to use it. We develop both at once, because that is how real players are built.
Every number above belongs to a real Diamond Blueprint athlete. Their words are on the results page.


A mentorship-driven player development program for serious high school baseball players, founded by two Clemson players: Aidan Knaak (Freshman All-American, 3-year ACC Friday night starter) and Dom Listi (D3 to Indiana State to Clemson). One plan, built around the player - physically and mentally.
Two. Aidan Knaak leads pitching development - he is starting ACC Friday nights at Clemson right now. Dom Listi leads hitting and mental performance - he earned his way from D3 to Indiana State to Clemson, where he played his final season. Both know the road your athlete is on.
Mentorship over drills. A lesson fixes a mechanic for an hour. A velocity program chases one number. We build the whole player - skills, mindset, habits and routines that compound - through an ongoing relationship, not an appointment.
No. Pitching is Aidan's side, hitting and the mental game are Dom's. Both sides of the game are covered.
Serious high school players who want the next level, and the families backing them. Athletes who want structure, honest feedback and a real plan.
Yes. We develop six areas, from pitching and hitting through mindset and recruiting preparation, guided by coaches who went through recruiting themselves - recently.
One plan, built around you. The coaches guide the skills work, the mindset and the weekly habits, adjust the plan as you develop, and hold you accountable to the routines that compound.
Apply through the site. The coaches review every application and take on athletes who are serious about their development.
If you are serious about your development and want mentorship that goes beyond drills, we would love to hear from you.
The first call costs nothing and sells nothing. It's a conversation about your goals with the coaches - that's it.
