Baseball pitchers play a vital role in the game. They are the players on the defensive side who throw the ball for the offensive side to hit. They are usually regarded as the key figures who dominate the outcome of the game. The following are some of the main rules about baseball pitchers:

1. Preparation before pitching

Static holding of the ball: The pitcher must keep the ball in front of him for at least 1 second before throwing the ball. This is to ensure the fairness of the game and prevent the pitcher from making a sudden attack.

Position requirements: The pitcher must be in the pitcher's box before pitching, and at least one foot must be on the pitcher's board when preparing to pitch. The pitcher's box is a circular area with a diameter of 5.49 meters, with a pitcher's board in the middle. The baseball field's requirements for the pitcher's box are that the pitcher's board is at least 25 centimeters above the ground and surrounded by a slope.

2. Pitching posture and action

Pitching posture: Pitchers can use two postures: frontal pitching and sideways pitching. Frontal pitching can only be thrown to the batter, and the action must be continuous and cannot be interrupted after it starts. Sideways pitching can be thrown to the base with a runner, but after the pitching action starts, it can only be thrown to the batter.

Pivot foot and free foot: When using the front pitching posture, the pitcher's pivot foot (pivot foot) should be on the pitcher's board, and the other foot (free foot) can stand freely without restriction. Before the pitcher throws the ball, neither foot can leave the ground, but when throwing the ball to the batter, the free foot can step back and then step forward.

Pitching Action: Before the pitcher adopts the front-facing pitching action on the pedal, he can pitch to the batter or stretch his free foot to pass the ball to the base with a runner. However, if he chooses to step back from the plate, he must first step back from the pivot foot and must step back from the plate. After the pitcher adopts the front-facing pitching posture on the pedal, he can no longer change to a sideways pitching posture or make a pitching arm extension action on the pitcher's plate.

III. Pitching Rules and Penalties

Strike and Ball: The balls thrown by the pitcher are divided into strike and ball. A strike requires that the ball does not land near home plate, and must pass over home plate, and the height must be above the batter's knees and below his armpits (this area is called the strike zone or strike zone). A ball that meets these conditions is called a strike, otherwise it is a ball. (Source: Baidu Encyclopedia)

Pitcher foul: If a pitcher violates the above rules during the pitching process, such as leaving the plate early, pitching inconsistency, pitching to a non-batter, etc., he will be judged as a "pitcher foul". At this time, if there is a runner on the base, the runner can safely advance to 1 base.

4. Pitcher Types and Division of Labor

Pitcher type: Pitchers can be divided into left-handed and right-handed according to their pitching hand. Since right-handed people are the majority, right-handed pitchers are more common in third-level baseball, A and B amateur baseball, and even professional baseball in various countries, while left-handed pitchers are relatively rare.

Division of labor in the game: According to the order of the game, pitchers can be roughly divided into starting pitchers and relief pitchers. The starting pitcher is the first pitcher of the two teams to pitch at the beginning of the game, and usually has strong endurance and suppression. The relief pitcher is the pitcher who takes over the starting pitcher in the middle of the game. According to the situation of the game, it can be further divided into long relief pitchers, short relief pitchers, relief pitchers, ace relief pitchers, etc.
