Baseball
under blacklights.

I am a professional left-handed pitcher for the Cosmic Chili Peppers, the touring team that started Cosmic Baseball. Fifty-one games in 2026, coast to coast, played under UV lights, in stadiums that mostly sell out.

This is also where everything I know about keeping an arm healthy lives. If you pitch, or your kid does, start here.

Train with me

Young arms are breaking down earlier than they used to, and most of it traces back to throwing without a plan and recovering without one either. Start free. Go deeper when you want to.

What Cosmic Baseball is

Real professional baseball played in the dark. UV-reactive balls, bats and uniforms, blacklights instead of stadium lights, and crowds that treat a Tuesday like a playoff game at a concert. ESPN, CNN, the Today Show and MLB Network have all covered it.

post-throw routine.

One page, five minutes, done before you leave the field. Most young pitchers throw their bag in the car and go, which is the single easiest habit there is to fix. Drop your email and I will send it over.
