Why Diamond Derby

A Way Back Into Baseball for Everyone.

Baseball creates fans for life, but eventually most people lose an easy way to participate.

I played baseball for as long as I can remember, from tee ball all the way through high school. But like so many others, baseball eventually became something I watched instead of something I played.

The space, equipment, time, and organization required to play became too complicated. Now it's been over nine years since I've taken a round of batting practice.

I kept coming back to two questions: Why does playing baseball require so many other people, schedules, and dependencies? Why can’t I just swing on my own terms?

Those questions became Baseball Lite: fewer barriers between people and the feeling that made them love baseball in the first place.

I'm building Diamond Derby because I know what it's like to grow up loving baseball and eventually have nowhere to play it.

I don't think that love for the game ever really goes away. The opportunities to play just become harder to find.

I want to make baseball more accessible to everyone, one home run at a time.
