At Seam Readers our mission is to help teach baseball and softball players of all ages one of the only constants when it comes to hitting. Seam Reading is the ability to identify a pitch based on how it looks. We say it is one of the only constants at the plate because every pitch has a certain rotation to it giving it a specific look. This skill is sometimes undertrained as well as un-taught and we want to change that. With our training system, the confusion on what to do at the plate is eliminated and Seam Readers all over the world are born.

The Makers Of Seam Readers

Our Story

Seam Readers was founded from an idea that originated 30 years ago by Dennis Tiefenthaler.  While the term “seam reading” was coined by Dennis, the skill originated in the 1870’s when baseball design we know today was invented.  In the early days, the skill was only taught to high level players and could only be taught in person.

Dennis made teaching the Seam Reading method his life mission. After training many players he recognized that while the method was effective, the limitations of strict face-to-face coaching would make it hard to teach these skills to the masses.  He knew there had to better way to teach players the many different faces a ball can have.

This is where Jared Tiefenthaler, Dennis’s son, entered the picture and changed the business. Jared already knew about the skill from his father and even practiced it himself when he played throughout his childhood. It wasn’t until Jared’s senior year in college where idea began to expand and the Seam Readers business as we know it today was born.

In Jared’s research he found that this skill is no longer taught or even known to players as it once was. This fueled Jared to create the Seam Reader App and Website where players can get an understanding of what Seam Reading is and train their eye to recognize what each pitch looks like.

The goal at Seam Readers has always been the same; to make kids better players by training their eyes as “Seam Readers.”
