Catching may be the most demanding position in baseball, both physically and mentally. To be a quality catcher, you need to know more than how to catch the ball and how to throw the ball to second, you need to know the game of baseball. When we talk about knowing baseball, we mean knowing it as a coach tries to know it. As the catcher, you're the onfield coach. You have the entire field in front of you. Your team depends on you to make split second decisions that can determine runs vs. outs, wins vs. losses.
