Catcher signals are vital in baseball, helping pitchers determine pitch type and location, making it challenging for batters to connect with the ball and leading to strikeouts or weak hits. Various types of catcher-pitcher signals exist, including hand signals, glove signals, and body movements, each with its unique advantages.

There are a variety of ways that this can be done, but the most common catcher signals generally involve flashing numbers with fingers and tapping body parts. Silent communication between the catcher and pitcher is necessary; being on the same page is a key to success during a baseball game for the pitcher and the catcher.
