How are pitchers getting signs from catchers in baseball games?

Pitchers in Baseball games typically receive signs from catchers through a series of hand signals. These signals are used to communicate the type of pitch to be thrown, such as a fastball or a curveball. The catcher will use a combination of finger placements and gestures to relay the desired pitch to the pitcher without the opposing team being able to intercept the signs. This method helps maintain secrecy and strategy during the game.
