The pitcher winds up to deliver the ball.
Although the object and mechanics of pitching remain the same for all pitchers, most pitchers are specialized depending on their effectiveness against certain types of hitters and the innings in which they commonly pitch. The names of some of these specialties include: starting pitcher, relief pitcher, closer and left-handed specialist.
Famous Major League Baseball pitchers include Cy Young, Nolan Ryan, Sandy Koufax, and Roger Clemens.
