thumb|267x267px|The grip used for a palmball In baseball, the palmball pitch is a type of changeup. It requires placing the baseball tightly in the palm or held between the thumb and ring finger and then throwing it as if throwing a fastball. This takes some of the velocity off the pitch, intending to make the batter swing before the ball reaches the plate.
