Baseball is a sport built on timing, deception, and precision. Few pitches capture those qualities quite like the forkball, a devastating off-speed weapon that has baffled hitters for more than a century. Though it isn’t as commonly thrown today as fastballs, sliders, or changeups, the forkball remains one of the most dramatic and difficult pitches in baseball’s long arsenal. Let’s take a closer look at its history, how pitchers use it, and the mechanics behind throwing this unique pitch.
The History of the Forkball
The forkball has roots going back to the early 20th century. It’s often credited to Bert Hall, a little-known pitcher in the 1910s, who experimented with an unusual grip that wedged the baseball between his fingers. Later, in the 1920s and 1930s, Bullet Joe Bush and Freddie Fitzsimmons were among the pitchers who popularized variations of the forkball, demonstrating its potential as a true off-speed out pitch.
But it wasn’t until the mid-20th century that the forkball gained real fame. Pitchers like Elroy Face and Jack Morris used it to carve out long, successful careers. In Japan, the pitch exploded in popularity in the 1970s and 1980s, where it became a staple in professional leagues. Many Japanese aces—including Hideo Nomo and later Kazuhiro Sasaki—brought the pitch to Major League Baseball, keeping its legend alive.
While it shares some DNA with the split-finger fastball, the forkball is slower, drops more sharply, and is considered harder to control. For this reason, its use has dwindled in today’s game. Still, it holds a special place in baseball history as a pitch that symbolizes both artistry and risk.
Uses of the Forkball
The forkball is designed to create deception and late movement. Unlike a fastball that relies on velocity or a curveball that depends on a big break, the forkball thrives on its ability to look like a fastball coming out of the hand but suddenly tumble as it nears the plate.
- Strikeout Pitch
The forkball’s sharp, late drop makes it a favorite in two-strike counts. Hitters often swing over the top of it, fooled by its fastball-like arm action and sudden disappearance. - Ground Ball Generator
Even when batters do make contact, the pitch tends to induce ground balls. Its downward motion often forces hitters to chop down, leading to routine infield outs and double-play opportunities. - Equalizer Against Power Hitters
Against sluggers who thrive on fastballs and breaking balls, the forkball serves as an unpredictable equalizer. It takes away timing, preventing hitters from getting comfortable in the box. - Complement to Other Pitches
Most pitchers who throw a forkball use it sparingly, mixing it in with fastballs and sliders. When used selectively, its rarity alone amplifies its effectiveness.
The drawback is that the forkball is notoriously tough to master. Because it requires spreading the fingers wide, it can put strain on the hand and arm, leading some coaches to discourage young pitchers from adopting it.
How to Throw the Forkball
The forkball grip is distinctive. The pitcher wedges the baseball deep between the index and middle fingers, spreading them apart like a fork—hence the name. Here’s a step-by-step guide:
- The Grip
Hold the ball with your index and middle fingers spread wide, so that the baseball sits deep between them. The thumb supports the bottom of the ball. Unlike a fastball grip that rests on the fingertips, the forkball sits closer to the palm. - Arm Action
Deliver the pitch with the same arm speed and motion as a fastball. This is crucial for deception—hitters should not see any difference in release. - Release
At the release point, allow the ball to “slip” out rather than snapping the wrist. The lack of spin, combined with gravity, creates the signature tumbling effect. - Follow-Through
Finish naturally, just as you would with a fastball. Over-torquing the wrist or forcing the drop can reduce control and increase injury risk.
The forkball is generally slower than a pitcher’s fastball—often in the 70–80 mph range compared to a fastball in the 90s. This velocity gap, paired with the late movement, makes it especially deceptive.
Why the Forkball Has Faded
Today, very few pitchers regularly throw the forkball. The split-finger fastball rose in popularity during the 1980s and 1990s because it was easier on the arm and more controllable. Teams and coaches also worry about the stress the forkball grip places on a pitcher’s hand and elbow.
Still, the pitch occasionally makes appearances in MLB and remains a cultural staple in Japan, where pitchers are more likely to develop it as part of their arsenals. For fans, it’s always a treat to see a forkball unleashed—the exaggerated drop is both visually dramatic and devastatingly effective.
Bottom of the Ninth
The forkball may be a rare sight in modern baseball, but its mystique endures. From its early pioneers in the 1910s to its dominance in Japanese leagues, the pitch has fascinated hitters and fans alike. While difficult to control and risky to master, the forkball’s ability to turn a confident swing into an embarrassing whiff remains unmatched.
For pitchers bold enough to attempt it, the forkball is more than just a pitch—it’s a statement of craft and deception, a reminder that baseball is as much about finesse as it is about power.
