How to Throw a Sinker or Two-Seam Fastball

We usually see most pitchers either put their thumb directly underneath the ball or just off-center. Likewise, the ring finger is placed on the side of the ball in order to help maintain control while the pinky finger is completely off. Looking at the GIF above, we can immediately see that the index and middle fingers are leveraged onto both seams.

If pitching is all about upsetting a hitter’s timing, then one of the best ways to do this is by changing speeds and using different grips. Pitchers who can command the two-seam fastball and throw it for strikes can use it to create bad swings on their more traditional and straighter four-seam fastball. The curveball is an off-speed pitch that breaks more from top to bottom (i.e., from 12 o’clock to 6 o’clock); thus, it changes visual planes to the batter. If the curveball is thrown incorrectly, it can put a lot of stress on the elbow and shoulder.

The ring finger and pinky finger rest on the side of the ball to give it balance. If released properly, four laces of the ball rotate through the air, helping to keep the throw in line with the target. This grip should also sit a little further into your hand. Additional grips are provided at the end of this post to give you more options to consider.

That causes the ball to sink to some degree, though this is not considered a “breaking pitch” and is thrown at full velocity. A 2 seamer should be thrown at or close to maximum velocity while providing added movement. Explore my pitching 2-seam grip workouts and throwing programs for players who work hard and don’t make excuses. The hand should be higher then and well outside the elbow at release point. Do not curl the wrist inside the forearm, this reduces ball velocity.

With a two-seamer, the ball moves in the same direction as whichever arm is being used to throw it (meaning a right-handed pitcher gets rightward movement on a two-seamer). The fastball umbrella includes many different pitches. The more grips that you can master and control, the bigger your advantage will be as a pitcher. Fastballs are not just about speed, but also the movement that you can use to upset a hitter’s timing and balance.

As you grip the ball, place more pressure with your index finger. A two-seam fastball is a pitch in baseball and softball. The pitch has the speed of a fastball and can also include late-breaking action caused by varying the pressure of the index and middle fingers on the ball. Throwing Long—Encourage pitchers to alternate using a changeup grip with fastball grips when throwing long. This helps players maintain good arm speed with the grip, which is essential to throwing a good changeup. To hold a two-seam fastball, place your index and middle fingers directly on top of the narrow seams.
