One of the most important pitches in a pitcher’s arsenal is the fastball.
A well-executed fastball can be a game-changer, leaving batters struggling to make contact.
Here, we’ll look at the mechanics and techniques behind throwing a fastball, specifically the two-seam and four-seam variations.
By understanding the nuances of these pitches, you can improve your pitching skills and become a more effective player on the mound.
The Basics of a Fastball
Before diving into the specifics of the two-seam and four-seam fastballs, it’s essential to understand the fundamentals of a fastball.
A fastball is a pitch thrown with maximum velocity and minimal spin.
The goal is to generate speed and create deception, making it difficult for the batter to react in time.
When throwing a fastball, it’s crucial to focus on proper mechanics and body positioning.
Here are some key elements to keep in mind:
- Balance: Maintain a balanced stance on the mound, distributing your weight evenly.
- Grip: Find a grip that feels comfortable and allows you to control the ball effectively.
- Arm Action: Use a smooth and fluid arm motion, generating power from your legs and core.
- Release Point: Consistency in your release point is vital for accuracy and deception.
The Two-Seam Fastball
The two-seam fastball, also known as the sinking fastball or two-seamer, is a pitch that moves downward and slightly to the throwing arm side.
It is often favored by pitchers who want to induce ground balls or generate movement.
Grip
The grip for a two-seam fastball involves placing your index and middle fingers along the seams of the ball.
The fingers should be positioned across the narrowest part of the seams, allowing for better control and movement.
Release and Movement
When releasing a two-seam fastball, focus on pronating your wrist slightly at the point of release.
This action creates natural movement, causing the ball to sink as it approaches the plate.
The amount of sink will vary depending on factors such as arm angle, grip pressure, and release point.
It’s important to note that the movement of a two-seam fastball is generally less pronounced than other pitches, such as a curveball or slider.
However, the slight movement can still be effective in inducing ground balls and weak contact.
How to Throw a 2-Seam Fastball
The Four-Seam Fastball
The four-seam fastball, also known as the rising fastball or four-seamer, is a pitch that typically travels in a straight line with minimal movement.
It is often favored by pitchers who want to generate high velocity and challenge batters with pure speed.
Grip
The grip for a four-seam fastball involves placing your index and middle fingers across the horseshoe-shaped seams of the ball.
The fingers should be positioned parallel to the seams, allowing for a clean release and maximum velocity.
Release and Velocity
When releasing a four-seam fastball, focus on maintaining a consistent arm slot and release point.
This will help maximize velocity and minimize any unwanted movement.
The goal is to throw the ball with a backspin, creating lift and reducing the effects of gravity.
Unlike the two-seam fastball, the four-seamer is designed to travel in a straight line, making it more challenging for batters to track and time their swing.
How to Throw a 4-Seam Fastball
Which Is Faster – 2-Seam Fastball or 4-Seam Fastball?
The four-seam fastball is generally the faster pitch when compared to the two-seam fastball.
The reason for the speed difference lies in the grip and the resulting aerodynamics.
The grip for a four-seam fastball — fingers across the seams — allows the ball to leave the hand with backspin and travel in a relatively straight line.
The “four-seam” name comes from the fact that, when thrown correctly, the batter sees the impression of four seams on the ball as it travels toward the plate.
The straight trajectory and backspin often allow for greater velocity.
A two-seam fastball, on the other hand, is gripped along the seams.
When thrown, the batter sees the impression of two seams.
This fastball is generally a bit slower than the four-seamer, but it compensates by having more movement.
Because of the way it’s gripped and thrown, a two-seam fastball often exhibits a sinking action or tailing movement away from the pitcher’s arm side.
Note that the exact speed of either pitch depends on the individual pitcher’s arm strength, mechanics, and grip.
So while the four-seamer is generally faster, there are pitchers who may throw a two-seamer with comparable speed due to their individual characteristics.
Also, the effectiveness of either pitch isn’t solely determined by speed; movement and location are also crucial.
2-Seam Fastball vs. 4-Seam Fastball: Movement and Control of Each
Both the two-seam fastball and the four-seam fastball are common pitches in baseball, and while they share the “fastball” name, they differ significantly in terms of movement and control.
Four-Seam Fastball
The four-seam fastball is the most straightforward pitch and the one most often taught to young pitchers.
It’s gripped with the fingers across the seams, which creates a stable, straight trajectory when thrown.
The rotation of the ball (four seams cutting through the air) helps to resist air pressure on the ball’s surface, leading to a more direct, less movement-heavy path.
Because of its straight path, a four-seam fastball often offers the pitcher more control and is typically used when a pitcher needs to throw a strike, especially a called strike.
It’s also the pitch of choice when a pitcher wants a high fastball, as the backspin on the four-seamer can create a slight “rising” illusion (though the ball doesn’t actually rise—it simply drops less than the batter expects).
Two-Seam Fastball
The two-seam fastball is gripped along the seams of the ball. When thrown, the pitcher imparts some side-spin on the ball, which interacts with the air pressure differently than a four-seamer.
As a result, a two-seam fastball often has more movement than a four-seam fastball, with the ball sinking or tailing toward the pitcher’s arm side.
While this added movement can make a two-seam fastball harder to hit, it can also make the pitch harder to control.
Some pitchers struggle to consistently command the two-seamer due to its unpredictable nature.
However, when thrown effectively, the two-seamer can induce more ground balls due to its sinking action.
In summary, a four-seam fastball generally offers more control with less movement and higher velocity, while a two-seam fastball can be more difficult to hit (and to command) due to its additional movement, despite a slightly slower speed.

Which Should a Pitcher Learn First – 2-Seam Fastball or 4-Seam Fastball?
When beginning to learn how to pitch, it’s generally recommended to start with the four-seam fastball.
The reasons for this are as follows:
- Simplicity and Control: The four-seam fastball is considered the most basic pitch. It’s typically thrown with a straightforward motion, and it tends to travel in a straight line, which makes it easier for young or inexperienced pitchers to control.
- Foundation for Other Pitches: Learning to throw a four-seam fastball correctly can provide a good foundation for other pitches. Once a pitcher can consistently throw a four-seam fastball for strikes, they can begin to learn other pitches, such as the two-seam fastball, curveball, or changeup.
- Safety: For young pitchers in particular, focusing on the four-seam fastball allows them to develop arm strength and good throwing mechanics without placing undue stress on their arm, which can occur when learning breaking pitches at a young age.
After mastering the four-seam fastball, a pitcher can then proceed to learn the two-seam fastball, which adds movement but requires more complex grip and release techniques.
Which Is Thrown More Often – Two-Seam Fastball or Four-Seam Fastball?
The four-seam fastball is generally thrown more often than the two-seam fastball at the professional level.
This can vary depending on the particular pitcher and their style, the team’s strategy, and trends within the game, but the four-seam fastball tends to be the most common pitch in baseball for several reasons:
- Speed and Control: As discussed previously, the four-seam fastball is usually the fastest pitch a pitcher throws, and it tends to have less movement than other pitches, making it easier to control.
- Countering Power Hitting: In the era of power hitting and launch angle optimization, many pitchers have turned to high four-seam fastballs to counteract hitters. A well-placed, high-velocity four-seam fastball can be one of the hardest pitches for a hitter to make contact with, especially if they’re trying to hit the ball in the air.
- Setting Up Other Pitches: The four-seam fastball is often used to set up other pitches. By establishing the fastball, pitchers can make their off-speed and breaking pitches more effective, as batters have to respect the possibility of the fastball.
That being said, the two-seam fastball is also an important part of many pitchers’ repertoires, especially for those who rely on inducing ground balls or who need a pitch that moves differently from their four-seamer.
Fastball vs. Slider vs. Curveball vs. Changeup – Grip, Speed, Control, Frequency Thrown at the Major-League Level
Fastball (Four-Seam)
Grip: The four-seam fastball is gripped with the index and middle fingers placed over the perpendicular seams of the baseball.
Speed: This is typically the fastest pitch thrown by a pitcher, often in the 90s to 100s mph at the major league level.
Control: The four-seam fastball usually has the most control due to its straight trajectory.
Frequency Thrown: This is the most frequently thrown pitch at the major league level.
Slider

Speed: Sliders are slower than fastballs but faster than curveballs, often in the low to mid-80s mph.
Control: Sliders have moderate control, but the late breaking action can make it more difficult to locate than a fastball.
Frequency Thrown: The slider is a common secondary pitch in the major leagues, often used as a strikeout pitch.
Curveball
Grip: The curveball is gripped with the index and middle fingers together, placed on or alongside the seam.
Speed: Curveballs are typically thrown slower than fastballs and sliders, often in the 70s to low 80s mph.
Control: Curveballs can be harder to control due to the significant break and slower speed.
Frequency Thrown: The curveball is a common secondary pitch, used to keep hitters off balance and induce weak contact.
Changeup
Grip: The changeup is often gripped deeply in the hand, with the index and middle fingers across the seams similar to a four-seam fastball.
Speed: The changeup is typically thrown slower than the fastball, often 10-15 mph slower.
Control: Changeups usually have good control, though the deep grip can make them harder to locate than a fastball.
Frequency Thrown: The changeup is a commonly thrown secondary pitch, used to disrupt a hitter’s timing.
Fastball vs. Sinker vs. Cutter
Fastball (Four-Seam)
As outlined above, the four-seam fastball is a fast, straight pitch that is thrown frequently and with high control.
Sinker
Grip: The sinker is typically gripped like a two-seam fastball but held slightly off-center.
Speed: The sinker is typically thrown at a similar speed to a fastball.
Control: The sinker has more movement than a four-seam fastball, which can make it harder to control but also more difficult to hit.
Frequency Thrown: The sinker is used less frequently than the four-seam fastball. Its use can vary widely depending on a pitcher’s style and repertoire.
Cutter (Cut Fastball)
Grip: The cutter is gripped similarly to a four-seam fastball but with the fingers slightly off-center.
Speed: Cutters are typically thrown just slightly slower than a pitcher’s fastball.
Control: Cutters usually have good control, but the late, sharp movement can make them more difficult to locate than a fastball.
Frequency Thrown: The cutter is less common than the four-seam fastball but can be a crucial pitch for certain pitchers. It is often used to counter hitters of the opposite handedness.
