Another type of catching that players must become skilled at is fielding ground balls. Because these are hit balls, they can sometimes be traveling much faster than a thrown ball, so it is even more crucial that good catching techniques are used by fielders; otherwise, the chances of an error are multiplied.
Before a ball is pitched, all fielders except the catcher and the pitcher should assume the ready position. In this stance, the player's feet should be slightly wider than shoulder-width apart, with the knees bent and the weight over the balls of the feet (see figure 8.4). The player's head should face the area near home plate. The hands should hang low between the legs, with the glove open wide. From this ready position, the player can get a good jump on the ball and move quickly in the direction it is hit.
