The Ultimate Guide To Baseball Signs (Catchers + Situational Signs)

Dec 02, 2025

Catching in baseball involves much more than just squatting behind the plate and receiving pitches. One of the most intriguing aspects of this role is the art of calling pitching signs, especially with a runner on second base.

At Catching Made Simple, we delve into the finer points of this art, equipping catchers with the knowledge and skills needed to excel.

In this article you’ll learn the 7 types of signs to use with a runner on second base and have the chance to start a free trial with The Headset App, the leading pitch calling app for youth baseball and softball.

The 7 Types of Catcher Signs (With a Runner on 2B)

Pitching signs are a complex language, a series of secret codes passed between the pitcher and catcher. There are various categories of signs, each with its unique purpose and method. Here’s a breakdown:

1. Standard Signs

  • First/Second/Third Sign: This is the most straightforward method. The catcher and pitcher agree beforehand whether the first, second, or third sign will be the actual pitch call. For instance, if it’s the first sign, and the sequence is 1 4 3 1 2, the pitch will be a fastball (1).

2. Indicator Signs

  • Number (”Chase the 2”): This common technique involves using the first occurrence of a specific number as the indicator for the next number to be the actual pitch.
  • Touch Part of the Gear/Body: Different parts of the catcher's body or gear can indicate which sign is 'hot.' For example, touching the wrist might mean the first sign is active, the elbow the second, and so on.

3. Body Language Signs

  • Glove Position (Buster Posey Style): The position of the glove can signal different pitches. Any other signs given are dummy signs meant to deceive the opposing team's runner on second.

4. Counting Signs

  • Flashes and Pumps: Here, the catcher counts the number of signs given, with a limit to avoid going too high. Pumps build on this by starting with the first number shown and adding the subsequent signs to it.

5. Changing Situation plus Number Signs

  • Outs plus One: The number of outs plus one determines the 'hot' sign.
  • Strikes plus Two: The number of strikes in the count plus three becomes the active sign.
  • Balls plus One: Similarly, the number of balls plus two dictates the 'hot' sign.
  • Innings plus One: This changes every three innings, with the inning number plus one indicating the pitch.

6. ‘Off’ Number Signs

  • Non-traditional Meanings: In this method, the usual meanings of numbers are altered (e.g., 1 might mean changeup instead of fastball). It's crucial to ensure the pitcher and catcher are on the same page to avoid confusion.

7. The Headset App

  • Press a Button, Hear the Pitch Call:  You can use the airpods that are already in your bag, and have a system like the pros. Your coach can tap a button from the dugout and the pitcher and the catcher and pitcher know exactly what they're throwing.

Bonus: Wipes

  • From the Pitcher’s Perspective: Instead of shaking off a sign, the pitcher can 'wipe' up to count or down to adjust the sign given by the catcher.

The Debate: Technology in Baseball Signs

Modern pitch-calling systems raise an intriguing question: Is traditional sign-calling still necessary in baseball? Just as football uses technology for play-calling, could baseball benefit from similar advancements? 

Some argue that it would speed up the game and improve safety, while others feel it would take away from the game's charm and tradition.

The Allure of Traditional Catcher Signs

Many fans and players love the complexity and nostalgia associated with traditional catcher signs. It's a unique element that adds a layer of strategy and mystery to the game.

The Case for Technology

On the other hand, embracing technology could streamline gameplay, enhance communication efficiency, and reduce the risk of crossed-up pitches, ultimately leading to a safer environment for catchers.

Fun fact: Lots of teams like the bone-conducting headsets (like the shokz opencomms) because it keeps the pitchers' ears open during the game.

Conclusion

Whether you’re a catcher, a coach, or a fan, understanding the nuances of pitching signs adds depth to your appreciation of the game. While the future may hold tech advancements, the art of sign-calling remains a vital and fascinating aspect of baseball.
