How To Throw A Sinker Like A Pro - What You Need To Know!

A sinker pitch is a type of pitch that is thrown with the intention of making the ball move downward as it approaches the plate. It is known for its ability to induce ground balls and double plays, making it an important weapon for pitchers at all levels of the game.

Learning how to throw a sinker is crucial for any pitcher looking to improve their effectiveness on the mound. By mastering this pitch, a pitcher can keep hitters off balance and induce weak contact, making it easier to get outs and keep runs off the board.

The sinker pitch has been a part of baseball for over a century, with some of the game's greatest pitchers utilizing it as a key part of their repertoire. In this section, we will explore the history of the sinker pitch and how it has evolved over time.

Understanding the Sinker Pitch

A sinker pitch is a type of fastball that has a natural downward movement due to its grip and release. It is also known as a two-seam fastball, as it is thrown with two fingers along the seams of the ball.

Beneath the surface, there are some significant differences between a sinker and other fastball pitches, such as a four-seam fastball. For instance, a sinker has a lower velocity than a four-seam fastball, but it makes up for it with increased movement. Additionally, the sinker is often thrown with a different grip than the four-seamer, which results in a unique release point and less spin rate.

Compared to breaking balls like curveballs or sliders, the sinker is a pitch that doesn't break as sharply. Instead, it moves in a more subtle but consistent way, which can make it difficult for batters to hit. The pitch's trajectory can also change depending on the pitcher's arm angle, which can make it even harder for batters to predict where the ball will end up.

When thrown correctly, the sinker pitch moves downward and towards the throwing arm side of the pitcher's hand, making it especially effective against batters of the opposite handedness. The pitch's movement is caused by the ball's backspin and the way it interacts with the air as it travels towards home plate.

The sinking action of the pitch is what makes it so desirable for pitchers to master. When a sinker is thrown correctly, it can induce weak ground balls, pop-ups, or even strikeouts. This can lead to a higher number of outs and lower pitch counts, which can ultimately save a pitcher's arm and benefit their team.

Grip and Mechanics of Throwing a Sinker

Grip used to throw a sinker pitch

The grip for a sinker pitch is a crucial aspect of throwing this pitch effectively. A pitcher must have a firm grip on the ball and hold it towards the bottom with the fingers. The thumb should be placed underneath the ball while the first index finger and middle fingers should be on the top of the ball with the middle finger resting on the seam. The grip for a sinker is similar to that of a two-seam fastball, but the fingers are spread slightly wider apart.

Proper throwing mechanics for a sinker pitch

To throw a sinker pitch effectively, proper throwing mechanics must be employed. The pitcher should start with a windup or stretch, depending on their preference, and move their arm back while keeping their elbow at a level that is slightly below their shoulder. As the pitcher strides forward with their front foot, they should bring their arm forward and release the ball with a slight downward motion. The release of the ball should be similar to that of a fastball, but the motion should be more downward and towards the front of the plate.

Common mistakes when throwing a sinker pitch

One common mistake when throwing a sinker pitch is releasing the ball too early or too late, which can cause the pitch to lose its downward movement and become ineffective. Another mistake is failing to keep the fingers spread apart during the grip, which can cause the pitch to turn into a fastball or lose its sink. Over-rotating the wrist can also cause the pitch to lose its sink and become a flat, hittable pitch. It's essential to practice the mechanics and grip of a sinker pitch consistently to avoid making these mistakes.

Variations of the Sinker Pitch & Sinking Fastball

A sinker pitch is a versatile and effective weapon in a pitcher's arsenal, and there are several variations of this pitch that can be used to deceive batters. In this section, we will explore the different types of sinker pitches and how they can be thrown effectively.

Two-seam and four-seam sinker pitches

The two-seam sinker is the most common variation of the sinker pitch. It is typically thrown with a grip that involves placing the index and middle fingers along the seams of the ball. This grip causes the ball to rotate along its axis, which gives it more lateral movement and a slight movement in the direction of the pitcher's throwing hand. The two-seam sinker is known for its ability to induce ground balls, making it a favorite among pitchers who rely on ground-ball outs.

The four-seam sinker, on the other hand, is a less common variation of the sinker pitch. It is thrown with a grip similar to that of a four-seam fastball, with the fingers placed across the seams of the ball. This grip allows the pitcher to throw the ball with more velocity and less movement than the two-seam sinker. However, the four-seam sinker is also less effective at inducing ground balls.

How to throw a sinking fastball

A sinking fastball is a variation of the fastball that has downward movement. It is often thrown with a grip similar to that of a two-seam sinker, with the fingers placed along the seams of the ball. The key to throwing a sinking fastball is to impart a slight spin on the ball, which causes it to drop as it approaches the plate. This pitch can be effective in inducing ground balls and weak contact, making it a valuable tool for pitchers.

Other off speed pitches that can be used with a sinker

There are several off-speed pitches that can be paired with a sinker to keep batters off balance. One common combination is the sinker-slider, in which the pitcher throws a sinker followed by a slider. The sinker sets up the slider by inducing the batter to swing early, while the slider breaks away from the batter's swing path. Another effective combination is the sinker-changeup, in which the pitcher throws a sinker followed by a changeup. The sinker sets up the changeup by inducing the batter to expect a sinking fastball, while the changeup drops off the table, causing the batter to swing and miss.

Overall, the variations of the sinker pitch give pitchers a wide range of options to keep batters off balance and induce weak contact. By mastering these different types of sinkers and their associated off-speed pitches, pitchers can become more effective on the mound and help their teams win games.

Benefits of Throwing a Sinker Pitch

Advantages for pitchers and their arsenal

Adding a sinker pitch to a pitcher's repertoire can provide several advantages. First, it can increase the number of pitch options a pitcher has, giving them more versatility on the mound. This can make it harder for batters to anticipate what type of pitch is coming, making it easier for the pitcher to get strikeouts and ground ball outs. Additionally, a sinker can be an effective tool for inducing double plays, as it has the potential to generate more ground balls.

The difficulty for batters to hit

Sinker pitches can be challenging for batters to hit due to their movement and velocity. The sinking motion of the ball can cause batters to swing over the top of the ball, resulting in ground balls and strikeouts. Additionally, because sinkers are typically thrown with a high degree of velocity, batters have less time to react to the pitch.

Potential for more ground balls and fewer fly balls

The sinker pitch's downward movement can result in more ground balls and fewer fly balls, which can be advantageous for pitchers. Ground balls are generally less likely to result in extra-base hits or home runs than fly balls, and they can also lead to double plays. Additionally, fly balls have a higher likelihood of being caught by outfielders, so inducing ground balls with a sinker can be an effective way to limit a batter's offensive potential.
