What is an outfielder/infielder?

[Tru_in_Blu]

Here's one of our rec league's bylaws, which is for ages 12-14:

Infield positions shall consist of a maximum four players plus the pitcher and catcher. Outfield positions will start each play "on the grass".

At this level, a sharply hit ball might have a chance to reach the outfield grass. Depending on the cut of the infield, the distance could vary from field to field. Very few balls are hit to "the outfield" and coaches tend to bring outfielders in as far as they can until a batter burns them.
