How to Throw a Cutter (Mechanics & Tips)

When it comes to baseball pitching, there are various techniques and pitches that can be used to deceive batters and gain an advantage on the mound.

One such pitch is the cutter, a versatile and effective weapon in a pitcher’s arsenal.

Here we’ll look at the mechanics, grip, and strategies behind throwing a cutter, as well as provide insights and tips to help you master this pitch.

The Basics of a Cutter

A cutter, also known as a cut fastball, is a pitch that combines the movement of a fastball with the late-breaking action of a slider.

It is thrown with similar arm speed and release point as a fastball, but with a slight wrist pronation at the point of release.

This pronation causes the ball to cut or move slightly in on the hands of a same-handed batter or away from a opposite-handed batter.

The Grip

The grip is a crucial aspect of throwing a cutter effectively.

The most common grip for a cutter is the “two-seam” grip, where the pitcher places their index and middle fingers along the seams of the baseball.

The fingers should be positioned across the seams rather than parallel to them.

This grip allows for better control and manipulation of the ball’s movement.

The Mechanics

Proper mechanics are essential for throwing a cutter with accuracy and consistency.

Here are the key steps to follow:

  • Start with a balanced stance on the pitching rubber, with your feet shoulder-width apart.
  • Hold the baseball with the two-seam grip, ensuring that your fingers are across the seams.
  • As you begin your windup or stretch, keep your throwing arm relaxed and loose.
  • As you reach the high point of your leg lift, rotate your hips and shoulders towards the plate.
  • As you stride towards the plate, maintain a consistent arm slot and release point.
  • At the point of release, slightly pronate your wrist to generate the cutting action.
  • Follow through with your throwing arm, maintaining good balance and posture.

Mastering the Cutter

Throwing a cutter effectively requires practice, refinement, and an understanding of how to use it strategically.

Here are some tips to help you master this pitch:

1. Focus on Finger Pressure

The amount of pressure applied by your fingers on the ball can greatly influence the movement of the cutter.

Experiment with different levels of pressure to find the right balance that produces the desired movement and control.

2. Work on Consistency

Consistency is key when it comes to throwing a cutter.

Practice the mechanics and grip repeatedly to develop muscle memory and ensure that you can consistently execute the pitch with precision.

3. Vary the Speed

While a cutter is typically thrown at a similar speed to a fastball, varying the velocity can add an extra layer of deception.

By occasionally throwing a slower or faster cutter, you can keep batters off balance and increase your effectiveness on the mound.

4. Mix Up Locations

Just like with any pitch, location is crucial.

Experiment with different locations to keep batters guessing and prevent them from getting comfortable in the batter’s box.

Aim for the inside corner against same-handed batters and the outside corner against opposite-handed batters.

5. Use the Cutter Strategically

Understanding when and how to use the cutter is essential for its effectiveness.

It can be particularly effective against batters who struggle with pitches on the inside part of the plate or against hitters who tend to pull the ball.

Use it as a complement to your other pitches to keep batters off balance.

Cutter vs. Sinker

Let’s compare the cutter and the sinker pitches in terms of their grip, mechanics, frequency thrown, and purpose:


  • Grip: The cutter is typically held with a four-seam grip, similar to a fastball grip. However, the index and middle fingers are positioned slightly off-center to the outside of the ball, creating a slight sidespin.
  • Mechanics: The pitcher applies pressure on the ball with the index and middle fingers to generate the desired spin. The release is similar to a fastball, but the off-center grip causes the ball to cut or break slightly towards the throwing arm side.
  • Frequency Thrown: The cutter is a popular pitch among many pitchers, particularly in recent years. It is often used as an alternative to a slider or a curveball. The frequency of its usage varies depending on the pitcher’s preferences and effectiveness with the pitch.
  • Purpose: The cutter is designed to deceive hitters by appearing as a fastball until it breaks late and moves slightly off the barrel of the bat. It can be effective against both left- and right-handed batters, as it moves in on their hands or towards the inside corner of the plate.


  • Grip: The sinker is typically held with a two-seam grip, where the pitcher places the index and middle fingers along the seams of the ball, often with a closer grip than on a four-seam fastball.
  • Mechanics: The pitcher throws the sinker with a downward arm angle and imparts backspin on the ball. This spin, combined with the grip, causes the pitch to sink or drop as it approaches the plate.
  • Frequency Thrown: The sinker is a common pitch among pitchers who aim to induce ground balls and generate double plays. Its usage frequency can vary depending on the pitcher’s style and effectiveness with the pitch.
  • Purpose: The sinker’s primary purpose is to induce ground balls by creating downward movement as it approaches the plate. Due to its sinking action, it can be particularly effective against hitters who tend to hit fly balls or struggle with pitches low in the strike zone.

Both the cutter and the sinker offer variations and challenges for hitters, but they achieve different effects.

The cutter focuses on late-breaking movement, often inside on hitters, while the sinker emphasizes inducing ground balls with its downward sinking action.

Pitchers may choose one or both pitches based on their repertoire and the specific situations they face on the mound.


FAQs: How to Throw a Cutter

1. What is the difference between a cutter and a slider?

A cutter and a slider are similar in terms of movement, but they differ in grip and velocity.
