Read on to know how to throw a sinker in baseball and some interesting facts about sinkers.
How to Throw a Sinker
Learning to pitch a sinker doesn’t have to be too challenging, here are the best tips that you can follow.
1. Find the Right Sinker Baseball Grip
- Using your dominant hand, hold the ball in a slightly outward position.
- Hook your middle and index fingers over the closest seam.
If you do not find it natural and comfortable, change the middle and index fingers a little by positioning them on the outside of the seams.
Your middle finger should rest in the middle of the ball because it’s the main pressure point when you throw the ball.
- Place your thumb directly below and between your middle and index fingers. The thumb should wrap the bottom of the ball to get a secure grip.
There are variations on how to hold a sinker. If the traditional sinker grip is uncomfortable for you, this alternative grip may work for you.
- Hook your middle and index fingers over the seam’s horseshoe.
- Place your thumb at the bottom of the ball, in between the middle and index fingers.
2. Get Into the Right Position
- Stand in your usual pitching position. Keep your upper body relaxed, knees bent, and feet and shoulder width apart. Position your body up. Your non-throwing arm should point toward the batting mound.
- Direct your throw towards the batter’s belt area. Make sure you don’t pitch above the waist of the batter as this will be an easy hit for them.
- Begin winding up. Take a step back to the second base, shifting your weight onto your back foot while bringing your knee up. Lean forward quickly and transfer your weight to your front leg as you are launching the ball to the batter.
Alternatively, assume a stretch position. Direct your feet and body toward the third base but face the home plate. Release the ball with a quick slide step or a high kick stance.
- Pivot your upper body toward the batter. Your torso should face the batter as you throw the ball. Keep your eyes on the waist level of the batter upon releasing the ball.
3. Release the ball
- Throw the ball over the top. Bring your arm forward while rotating your arm high and bring it down after throwing the ball. Be careful not to rotate the arm too much as this can lead to injury.
- Hold the ball tightly using your fingers and thumb until the moment you throw it.
- Apply high pressure to the middle finger before throwing the ball. Sidespin is derived by placing your index finger ahead of the middle finger.
- Slightly twist your hand outward as you release the ball. This is called pronation, which can facilitate horizontal movement of the ball before dropping over the home plate.
By taking a series of sinker pitching lessons, you can get the hang of it eventually. You will also know the sinker grip and release that work best for you.

Reasons Why a Sinker Sinks
How is it possible for a ball that is traveling at a horizontal path to suddenly drop sharply toward the ground just as it is approaching the hitter? Here’s the answer.
- A mixture of spins helps sink the ball. Applying less pressure in the middle of the ball and more pressure in the inside edge as you release the ball from your fingertips can create fewer spins, causing a heavy sinking movement.
- A slower spin rate causes the ball to spin downwards. Sinkers don’t resist gravity as compared to fastballs with faster spins.
1. Sinker vs 2-SeamSinker is a variant of a two-seam fastball with a speed of 80 to 90 miles per hour. If the ball sinks a lot, then it’s a sinker, but if it doesn’t, then it’s a two-seamer.
In a sinker pitch, you apply more pressure on the middle finger, but in a two-seam fastball, it’s on the index finger.
2. Sinker vs Slider
Both differ in grips and motions, but they are both great at deceiving a batter.
Sinker is a fastball variant while the slider is a type of breaking pitch. Sinker travels at a greater velocity than sliders (6 to 8 mph slower).
Sinker pitch movement follows a horizontal path, whereas sliders move sideways For right-handed pitchers, the ball moves from right to left, and for the left-handed, it moves from left to right.
What is a sinker?

Why is it called a sinker pitch?
As its name implies, a sinker is a fastball that sinks as it’s about to reach home plate. The ball remains in a horizontal flight path from when it was thrown until it’s approaching the hitter. And then it suddenly dips swiftly towards the ground, either just slightly before or right on home plate.

How do you grip a sinker?
First, a proper grip is necessary. For others, a two-seam sinker works well with them, but others find the one-seam sinker better.
In a one-seam sinker grip, your index and middle fingers should be placed on top of a single seam. Pronate slightly your fingers and hand on the inside of the ball to create a slightly tilted spin. This prevents the ball from resisting gravity and causes it to sink sharply.
Why is it hard to hit a sinker?
It’s because of its high velocity and deceptive trajectory. Batters may think that they are getting a straight fastball, but then the ball drops dramatically until the last second. Once the ball sinks, the batter might not hit the ball and end up with a ground ball.
When to throw a sinker pitch?
