Sinker

In baseball, the Sinker is a pitch that drops suddenly as it closes in on the plate. This pitch is gripped hard with your middle and index finger over the narrow area of the seams and released with a slight turn of the wrist. The sinker is designed to miss bats, but to induce groundballs if contact is made. Before retiring in 2005, Kevin Brown was the owner of one of the nastiest sinkers in baseball.
