windup in baseball

The windup position in baseball has undergone significant changes over the years, particularly with the rule adjustments made in 2007. These changes, implemented by the Official Playing Rules Committee, have redefined how pitchers can position their feet on the rubber.

No longer required to have their entire pivot foot in contact with the rubber, pitchers now enjoy greater flexibility, allowing only a portion of their pivot foot to touch the rubber.

This adjustment not only modernizes the game but also aligns with common pitching practices. Understanding these rules is crucial, whether you’re a seasoned pitcher or a baseball enthusiast.

The new guidelines enable pitchers to place their free foot in various positions around the rubber, offering more strategic options during gameplay.

Dive into the intricacies of these windup position rules and see how they continue to shape baseball’s dynamics.

Overview of Windup Position in Baseball

In baseball, the windup position is one of two primary pitching positions, the other being the stretch.

The windup is typically used when there are no baserunners or when there are runners on base but no immediate threat of stealing. Here’s an overview:

Definition and Importance

The windup position is one of the two legal pitching positions in baseball, with the other being the set position.

In the windup, the pitcher starts with their pivot foot touching the pitching rubber and faces home plate, allowing for a smooth transition into the pitching motion, thereby maximizing power and control.

A well-executed windup can improve a pitcher’s effectiveness and make it harder for the batter to predict the pitch. This position is usually used when there are no runners on base or when the pitcher aims for a more deceptive pitch.

Rules Governing the Windup Position

Several rules govern the windup position to ensure fairness and consistency:

  • Pivot Foot Placement: The pivot foot must be in contact with or immediately in front of the rubber. This alignment is crucial for maintaining balance and delivering the pitch smoothly.
  • Body Orientation: The pitcher must face home plate, ensuring they have a direct line of sight to the target.
  • Free Foot Position: The free foot can be either behind the pitching rubber or beside the pivot foot. This flexibility helps pitchers adjust their stance for greater effectiveness.
  • Motion Restrictions: Once the pitcher starts the windup motion, they must complete it in one continuous movement. Stopping or pausing can result in a balk, which advances any base runners.

Key Elements of the Windup Position

The windup position in baseball is crucial for pitchers, as it sets the foundation for their delivery. Here are the key elements:

Positioning of Feet

Correct foot positioning is crucial in the windup position. The pivot foot must be in contact with the pitching rubber. For a right-handed pitcher, this is the right foot; for a left-handed pitcher, it’s the left foot.

The free foot should be positioned either in front or to the side of the rubber, but it cannot extend beyond the front edge of the rubber. This alignment ensures a stable base and maintains balance throughout the pitching motion.

Body Alignment and Posture

Proper body alignment enhances both power and control during a pitch. As you engage the pitching rubber, your shoulders should be aligned towards home plate. The head stays steady, focused on the target.

Avoid excessive leaning or bending as this disrupts balance and affects pitch accuracy. The upper body should remain upright, and the hands must separate smoothly once the pitching motion begins.

This setup allows for a fluid motion, generating maximum velocity and precision.

Comparing Windup and Set Positions

Comparing the windup and set positions in baseball pitching reveals distinct differences in mechanics and when each position is typically used:

Differences in Rules

The windup position involves specific rules for foot placement and movement. During the windup, the pitcher must start with their pivot foot on the pitcher’s rubber and can step back or sideways but not forward.

They need to maintain contact with the rubber until the ball is released. In contrast, the set position requires the pitcher to have both hands in front of their body and come to a complete stop before delivering the pitch.

The set position also limits movements to ensure quick and efficient execution, crucial for managing base runners.

Strategic Use in Games

The windup position is ideal when there are no base runners or when the lead runner is on third base, as its slower execution is less risky in these situations.

By allowing for a more deliberate and powerful motion, the windup can generate greater pitching velocity and control.

Meanwhile, the set position is preferred when runners are on base. Its faster execution makes it harder for base runners to steal bases, thus providing an essential tactical advantage for the defensive team.

Effective use of the set position can help prevent stolen bases and maintain game control.

Common Violations and Penalties

Common violations and penalties in baseball vary depending on the context of the game, but here are some general ones that cover a variety of situations:

Types of Violations in Windup Position

Pitchers must adhere to specific regulations in the windup position to ensure fair play. Several common violations occur, which can impact gameplay:

  • Illegal Foot Placement: If a pitcher’s pivot foot isn’t in contact with the pitcher’s plate, it’s an illegal pitch. This rule aims to prevent unfair advantages.
  • Improper Body Orientation: The pitcher must face the batter with their shoulders squared. Failing to do so can result in a balk.
  • Inconsistent Motion: Any abrupt stop or deviation from a natural pitching motion can lead to a balk. This includes quick pitches or double starts.
  • Foreign Substance Use: Applying foreign substances to the ball alters its behavior and is prohibited, resulting in immediate ejection if caught.

Impact of Violations on Gameplay

Violations in the windup position have various consequences that affect the game’s flow and strategy:

  • Balks: A balk allows base runners to advance, impacting scoring opportunities and pitcher strategy.
  • Illegal Pitches: These result in balls being automatically added to the count, providing the batter with a strategic advantage.
  • Ejections: Using foreign substances leads to immediate ejection, disrupting team dynamics and forcing bullpen adjustments.
  • Penalties for Re-entering: Substitutes must follow strict re-entry rules, limiting a team’s flexibility during the game.

Frequently Asked Questions

Can a balk be called in the windup?

Yes, a balk can be called if there is any fluidity between receiving the sign and throwing home that skips the set, or if a pitcher flinches during the set. A pitcher cannot switch from the windup back to the set without fully stepping off the pitching rubber.

Do pitchers still use the windup?

Yes, pitchers can use the windup position or the set position. Both positions are legal and can be used depending on the game situation and strategic decisions.

What are the rules for pitching windup?

In the windup position, a pitcher must have his pivot foot on the pitching rubber and his shoulders facing the batter to some degree. He can take a step back or to the side with his free foot when starting his delivery.

What happens if a pitcher takes too long to pitch?

If a pitcher takes too long to deliver the pitch and violates the pitch timer, they are charged with an automatic ball.

What is the golden rule of pitching?

The golden rule of pitching is to have a concise pitch that grabs attention quickly, ideally within 10 seconds. This is crucial for making an impactful impression.


Mastering the windup position is essential for any pitcher aiming to excel in baseball. By understanding and adhering to the rules, you not only ensure fair play but also enhance your strategic options on the mound.

Avoiding common violations like illegal foot placement and improper body orientation can save you from costly penalties and ejections.

Remember, consistency in your windup can significantly impact your performance and the overall gameplay experience.

Stay focused on the fundamentals and keep refining your technique to become a more effective and reliable pitcher.

Moreover, continually studying and observing successful pitchers can offer valuable insights. Incorporate regular practice sessions and seek feedback from coaches to fine-tune your skills.
