How to Throw a Curveball with a Wiffle Ball

Mastering the Curveball Using a Wiffle Ball

1) Grip the wiffle ball with two fingers on the side with the thumb wrapped around the ball. Put one of the fingers in the whole on the wiffle ball and the other one gripping the side of the ball.

2) Throw the ball in a karate chop motion and snap the wrist to get ultimate spin. 

3) Follow through to get adequate results. 

Why Are My Curveballs Not Curving?

Your curveballs may not be curving for several reasons. 

First, make sure you have the correct grip on the ball. Two fingers on the side and the thumb on the other side.

Second, your throwing motion could be off. Make sure you are throwing the ball like in a chopping motion. 

Third, make sure you are flicking your wrist to get spin on the ball. Watch major league baseball players throw curve balls and see how they grip it and turn their wrist over. 

Common Mistakes to Avoid

When learning how to throw a curveball, there are a few common mistakes that pitchers make. One of the most common mistakes is an improper grip on the ball. This can result in a pitch that doesn't break or breaks too sharply. Another mistake is insufficient spin or velocity, which can cause the pitch to hang in the air or not break enough.

Accuracy is crucial when throwing a curveball. A pitcher must release the ball at the right point in their delivery to ensure that it breaks in the desired location. This takes practice and a keen sense of timing.

By paying close attention to these issues and practicing regularly, you can avoid mistakes and improve your pitch over time. Remember, the curveball is a difficult pitch to master, but with dedication and hard work, it can become a powerful weapon in your pitching repertoire.

Perfecting Your Throwing Technique

Now that you have a grip on the basics of throwing a curveball with a wiffle ball, it's time to work on perfecting your throwing technique. This involves a range of factors, including your stance, arm motion, release point, and more.

The Importance of Proper Stance

Getting your stance right is crucial to throwing an effective curveball. You want to ensure that your feet are shoulder-width apart, your throwing arm is fully extended, and your other arm is pointing in the direction of the pitch.

Arm Motion and Release Point

As you prepare to throw the curveball, you want to focus on getting your arm motion and release point right. The exact technique will depend on your grip and throwing style, but generally, you want to start with a slight windup and flick your wrist at the end of the pitch to create spin. I always think of it as throwing a ball in a chopping motion. The ball will go a lot slower than your fastball, but you should see some movement on your ball making it harder for the batter the hit. 

Follow-Through and Recovery

Finally, don't forget the importance of follow-through and recovery when throwing a curveball. After releasing the ball, you want to complete your throwing motion to help with accuracy and avoid injury. Additionally, you want to be prepared to field the ball in case of a hit or missed catch.

Finger Placement and Pressure

Once you've found the right grip on the ball, it's time to perfect your finger placement and pressure. Typically, you want to keep your fingers close together and apply pressure to the top of the ball to create spin. However, the exact technique may vary depending on your grip style.

It's important to note that the amount of pressure applied to the ball can affect the amount of break on the pitch. Too much pressure can cause the pitch to break too sharply, while too little pressure can result in a pitch that doesn't break at all.

History of the Wiffle Ball

The wiffle ball was invented in 1953 by David N. Mullany, a man with a passion for baseball who wanted to create a ball that could be safely played in backyards and other small spaces. Mullany was inspired to create the ball after watching his son and friends play a game of baseball using a plastic golf ball and a broomstick handle. Mullany saw the potential for a safer, more durable ball that could be used for backyard games and began experimenting with different designs. After months of trial and error, Mullany finally came up with the wiffle ball, which quickly became a hit with kids and adults alike. Over the years, the wiffle ball has become a beloved staple of outdoor games and an increasingly popular sport in its own right.

Key Features of a Wiffle Ball

Wiffle balls are known for their unique features, including the holes that cover the ball's surface and its lightweight, hollow construction. These features make the ball easier to handle and throw with precision, allowing pitch types that aren't possible with a standard baseball. The holes on the ball's surface also make it easier to grip, which is essential for throwing different types of pitches. Additionally, the ball's lightweight construction means that it won't hurt as much if it hits someone, making it a safer option for backyard games.

Differences Between a Wiffle Ball and a Baseball

While a wiffle ball and baseball may seem similar at first glance, there are some key differences that impact how you throw the ball. For one, a wiffle ball's unique design makes it lighter and easier to handle, while its smaller size requires more accuracy in throwing. Additionally, since wiffle balls are made with plastic, they don't travel as far as baseballs. This means that you'll need to adjust your throwing technique when using a wiffle ball, as the ball won't carry as far as a baseball. Another key difference is the type of pitches that can be thrown with a wiffle ball. Due to its lightweight construction and perforated design, a wiffle ball is ideal for throwing pitches with a lot of movement, such as curveballs, sliders, and knuckleballs. The wiffle ball is much more subject to wind 

Overall, the wiffle ball is a unique and versatile ball that has become a beloved part of backyard games and sports. Whether you're playing a casual game with friends or practicing your pitching skills, the wiffle ball is a fun and challenging option that offers a range of possibilities.

The Science Behind a Curveball

Now that we've gone over the basics of the wiffle ball, let's take a closer look at the mechanics of throwing a curveball. Understanding the science behind the pitch is essential to mastering it.

Throwing a curveball is one of the most challenging pitches in baseball, but it's also one of the most effective. A well-executed curveball can leave batters swinging at air and wondering what just happened. So, what makes a curveball so tricky to hit?

The Magnus Effect

At its core, a curveball works by taking advantage of the Magnus effect, which is the phenomenon that occurs when a spinning object experiences a lift force perpendicular to its direction of motion. Essentially, the spin of the ball creates a pressure differential that causes it to move in a curved path.

Think of it this way: when a pitcher throws a curveball, they're essentially throwing a spinning ball, which creates an area of low pressure on one side of the ball and an area of high pressure on the other side. The ball then moves in the direction of the low-pressure area, which causes it to curve.

Factors Affecting the Curveball's Movement

Various factors can impact how much a wiffle ball curvatures, including the speed at which it's thrown, how much spin is applied, and the air temperature and humidity. By adjusting these factors, pitchers can control how much their curveballs break.

For example, a pitcher can throw a harder curveball by increasing the spin rate on the ball. This will cause the ball to move more erratically, making it harder for batters to predict where it will end up. Alternatively, a pitcher can throw a slower curveball by decreasing the spin rate, which will cause the ball to break less but still move in a curved path.

The air temperature and humidity can also impact a curveball's movement. In general, a curveball will break more in humid conditions because there is more moisture in the air, which creates more resistance on the ball. Conversely, a curveball will break less in dry conditions because there is less resistance on the ball.

Importance of Spin and Velocity

When throwing a curveball, spin and velocity are crucial to getting the right movement. Ideally, a pitcher should apply enough spin to the ball to cause it to curve while also throwing it fast enough to keep it from dropping too much. Too much spin, too little spin, or too slow or fast a speed can all impact the pitch's movement.

Additionally, the pitcher's release point and arm angle can also impact the curveball's movement. A pitcher who releases the ball from a lower arm angle will create more topspin on the ball, which will cause it to break downward. Conversely, a pitcher who releases the ball from a higher arm angle will create more backspin on the ball, which will cause it to break upward.

Mastering the curveball takes time and practice, but understanding the science behind the pitch is the first step. By adjusting the spin rate, velocity, release point, and arm angle, pitchers can control the movement of their curveballs and keep batters guessing.

Expanding Your Pitching Arsenal

While mastering the curveball is an excellent skill to have in your wiffle ball game, it's essential to expand your pitching repertoire to keep batters on their toes. There are several other pitches you can learn to complement your curveball and create a more well-rounded pitching arsenal.

One popular pitch is the slider, which is a breaking pitch that moves laterally across the plate. To throw a slider with a wiffle ball, you can use a similar grip to the curveball but adjust the release point and finger pressure. Experiment with different techniques to find the right combination of spin and movement.

Another effective pitch is the knuckleball. The knuckleball is notorious for its unpredictable and erratic movement, making it extremely challenging for batters to track. To throw a knuckleball with a wiffle ball, you'll want to hold the ball with your fingertips, ensuring minimal spin and relying on the air resistance to create movement. Developing a knuckleball can take time and patience, but it can be a valuable addition to your pitching repertoire.

By incorporating different pitches into your game, you'll keep hitters guessing and increase your chances of success on the mound. Practice these pitches regularly, refine your technique, and observe the movement and reactions of batters to fine-tune your skills and become a formidable wiffle ball pitcher.


Now that you know the science behind the curveball with a wiffle ball, how to grip the ball, and how to throw it effectively, you're ready to take your wiffle ball game to the next level. It may take some practice and experimentation to perfect your technique, but with time and dedication, you can wow your friends and opponents with your curveball skill.
