Instead of trying to read a pitcher’s mind, read the seams of the ball… they never lie.”  Jared Tiefenthaler, Co-Founder, CEO Seamreaders

Ladies and gentlemen, thank you for reading our first blog of all time.  I am Dennis Tiefenthaler, an ex-professional baseball player, co-founder, and a consultant of Seam Readers Worldwide.  My son Jared and I are going to be sharing with you weekly content.  Our mission is going to be to introduce and instruct you on a skill almost as old as the game of baseball itself.  We call it Seam Reading. It’s the ability to identify a pitch based on how it looks.  Each pitch has a signature look which is created by the rotation of the seams on the front of the ball as it is released out of the pitcher’s hand.  Do you know what a slider looks like? How about a rise-ball? Have you ever thrown them before? If you grip a ball differently, it will look differently coming at you. It is just common sense, agreed? We believe what we have just said cannot be argued.

In the next weeks and months, we will be bringing you articles, videos, and interviews of past and current MLB players and coaches, who will tell you that this skill is the best way to learn what the hardest thing to do in sports, which is to hit a baseball or softball.

In conclusion, we at Seam Readers believe that if your son or daughter is not being taught the many faces of a pitch that they could see, then they are not being taught true pitch recognition. If you are not seam-reading, then you are blind to an obvious giveaway that has no disguise. No matter how much a pitcher tries to hide their pitches, that slider will always look like a slider, and that rise-ball will always look like a rise-ball.
