Editing Infielder (section)

===Corner infielders===
The first baseman and the third baseman are the corner infielders.

The third baseman primarily fields balls hit and bunted down the third base line, but can also attempt to reach balls hit between second and third base. Although the third baseman does not need to cover as great a range as the shortstop or second baseman, the position requires greater anticipation and quicker reflexes, since the third baseman may be standing only 90 feet from the batter and sometimes much less; thus, he has much less time to react to hit balls than the shortstop or second baseman. The third baseman must also have a strong arm since the throw from his position to first base is the longest on the infield.

The first baseman is largely responsible for keeping one foot on first base while catching throws from the other three infielders before the batter can reach first base. These throws are often hurried and thus off-target. A player who is tall and has long arms may be a good candidate for first baseman because these attributes help him handle off-target throws. The first baseman must be able to cleanly field thrown balls that hit the ground before they reach first base, and to quickly decide to abandon first when necessary to catch an especially bad throw. Since the first baseman mostly stands close to his base, his mobility and throwing skills do not need to be high; good hitters who are slow of foot are often placed at first base. In some cases, an aging third baseman or [[outfielder]] who has lost some speed but is still a good hitter will be moved to first base to keep his bat in the line-up.
