Our Baseball Epiphany

Our “baseball epiphany” came as we watched youth baseball being taught throughout the country. We saw kids consistently struggle with their swings and we had a hunch the problem was more than poor technique. Players were experiencing setbacks because their bats were too heavy or too light, too long or too short.

We recognized that bat “fitting” had never been part of the performance and development equation for youth…and that had to CHANGE.


What do we mean by fit? With decades of experience in the golf industry, we witnessed the transformation that saw club fitting become the standard in the game. A real golfer will almost never purchase a club without first matching personal metrics and goals to club measurements and performance. This is the only way to be confident in club selection. We realized the same principles that had become the standard in one sport (golf) had hardly been considered in another (youth baseball). The current bat selection process involves far too much guesswork.

TRUE Diamond Science bat tested over 3,000 youth athletes to develop a one-of-a-kind fitting algorithm and proprietary bat prescription methodology!


Through world-class data analytics, we learned that getting the right bat in the hands of a youth player didn’t make a small difference, it makes ALL the difference! The incredible team at TRUE developed proprietary technology including launch monitors, batting analysis stations, and custom algorithms to create the most precise fitting experience EVER at the youth level. The result? Incredible data about players’ individual abilities and an accurate process that pairs the player with the bat that is guaranteed to improve their game.


What is different about
TRUE Diamond Science?

We are not focused on exotic baseball trends and gadgets. We're not a marketing machine that is trying wow you with flashy colored bats that claim they are the next BIG THING.

We are focused on ONE THING...


Fitting your youth athlete with the correct bat!

"I'm not a real fan of just saying - here's a sheet, go buy a bat but if you can go try it out at a batting cage like this and see how much better he's swinging the bat, I think it's well worth the experience."

"I would 100% totally recommend this product. You know what your getting and I guarantee you a lot of parents would much rather spend a couple hundred dollars on something that's geared to fit their child"
