The centre fielder must back up second base on all throws from the catcher, and also on throws from any other position, whenever possible. On throws from the direction of first base he will be assisted by the left fielder and from the direction of third base by the right fielder. When a runner is stealing second base and the catcher's throw is wild, the centre fielder must meet the ball quickly so as to prevent the runner from going on to third. In a case of this kind a crafty runner will often make a feint to run to third in order to force the fielder to throw the ball in the hope that he may throw it wild. If there is a probability that the runner actually intends to go to third, there is nothing left the fielder but to throw and take the chance. But if the fielder has good reason to suspect the honesty of the runner's intentions, a quick throw to second, instead of to third, will often catch him before he can return. The centre fielder should also back up the left and right fielders on all hits along the ground which either-of them runs in to meet. It gives one fielder more confidence to go in quickly after a ball if he knows there is another fielder behind him to stop it in case it passes himself. Even on an in-field hit to the second baseman or short-stop the out- fielder should move in at once, so as to be able to recover the ball quickly if it gets through the in-field. When a runner is caught between first and second or second and third bases, the centre fielder should get in line with the play, back of second base. For, while only four players take an active part in such a play others should back up to provide for the possibility of a wild throw. The necessity of "calling" for a fly hit applies with particular force to the centre fielder. As soon as he has seen that he can get to a hit and has decided to take it, he calls out loudly so that every one must hear, "I'll take it," and all the other fielders near him respond, "Go ahead." This will avoid all danger of collisions to which he is specially exposed by having a fielder on either side. On all high flys to another out-fielder he should go near the fielder who is attempting to make the catch, so that if the ball is missed and bounds his way, he can recover it quickly and prevent runners from gaining extra bases.
