Depending on the grip and pressure applied with the fingers, sometimes the two-seam fastball features more sink than lateral movement. Sinkerballers tend to induce a lot of ground ball outs because hitters tend to swing over the ball due to the late downward movement, thus often end up beating the ball into the ground. Roberto Hernández of the Philadelphia Phillies, Justin Masterson of the St. Louis Cardinals, Derek Lowe of the New York Yankees, Tim Hudson of the San Francisco Giants, Aaron Cook of the Colorado Rockies, Clay Buchholz of the Boston Red Sox, Roy Halladay of the Philadelphia Phillies, Chris Volstad of the Chicago White Sox, Trevor Cahill of the Chicago Cubs, and Bronson Arroyo of the Arizona Diamondbacks are or were well known for their sinkers, consistently ranking high in the league in ground ball-to-fly ball ratio.
