knuckleballs
Grip-light baseball tosses
Knuckleballs are pitches in baseball thrown with minimal spin, gripped with the fingernails or knuckles pressed against the ball.
The lack of rotation causes the ball to flutter unpredictably through the air, making it difficult for both batters and catchers to track.
His knuckleballs danced all over the strike zone.
Pitchers who specialize in the pitch are called knuckleballers.
