Where must the pitcher take his sign from?

The pitcher must take his sign from the catcher. This is the standard practice in baseball, as the catcher is responsible for signaling the type of pitch to be thrown and other strategic elements of the game. The communication between the pitcher and catcher is vital for coordinating plays. The catcher uses signs to indicate their desired pitch, positioning, or strategy, ensuring that the pitcher knows what to throw and when. This relationship is essential for effective pitching and defensive strategy.

Taking signs from the dugout or the umpire is not standard practice, as they do not engage directly in pitching strategy. The batter, on the other hand, is focused on preparing to hit and does not provide instructions to the pitcher. Proper communication between the pitcher and catcher helps maintain the flow of the game and can greatly influence its outcome.
