Fifth Infielder
The Pitcher Plays a Dual Role

Pages 6–7 · Phillips Petroleum Company, 1953
A pitcher can lose a well pitched game by his own inefficiency as a fielder. By his slowness, after he has released the ball, in going after a bunt. By his unbalanced position (again after he has released the ball) which prevents him from knocking down a line drive hit back through the box. By his failure to cover first base on a ground ball hit toward the first baseman. By his refusal to back up third base or home plate on a throw from the outfield.
As a rule, the pitcher doesn’t have as many fielding chances as the four infielders. But he plays a vital role in the defensive pattern. When he does make an error of omission or commission in a close game, it usually is costly.
If, instead of following the flight of the pitched ball you will occasionally keep your eyes riveted on the pitcher, you will notice that many of them finish their follow-through with their weight on one leg and their bodies turned sideways to the batter. This lack of balanced weight distribution and this failure to face the batter head-on prevents the pitcher from:
1 — Breaking quickly to either side of the mound to field bunts or topped rollers.
2 — Knocking down line drives that are hit back directly at him. Sometimes an unexpected line drive causes a pitcher serious injury.
On every ground ball hit toward the first baseman, the pitcher should rush toward first base. The first baseman may be able to make the play unassisted, but the pitcher never should take that for granted.
Suppose the first baseman fumbles the ball. By covering first the pitcher can save the play. He should also get over there quickly enough so he won’t have to handle the throw and find the base at the same split-second. This way he will also cut down the possibility of a collision with the runner and, perhaps, costly injury.
The pitcher has no excuse for not backing up every throw made from the outfield to third base or home plate. The outfielder may make a wild throw. Even the most accurate throw may elude the third baseman or the catcher. A perfect throw can take a bad hop over the third baseman’s or catcher’s head. Or the ball may hit the runner as he’s sliding and carom off to one side.
A pitcher who is backing up the play at third often can prevent the runner from continuing on to score. A pitcher who is backing up the play at home plate may prevent a second runner from scoring or other runners from advancing an extra base.
So, remember that the pitcher has more to do than fool the hitter. Remember that he’s the fifth infielder and

- WATCH the position of his feet and body on his follow-through.
- WATCH to see how well he goes after a bunt.
- WATCH to see if he knocks down liners, converts them into outs.
- WATCH to see if he covers first on grounders hit toward first.
- WATCH to see if he backs up third or home on outfield throws.
