Too many infielders?

I've never heard of anything either. Of course, its possible that this is a local rule. Come to think of it though, I've never seen this in any ruleset.

The closest thing I can think of is co-ed in college intramurals, where they didn't want men fielding all the "important" positions and phasing out the women from fielding. This also included "overfielding", but did nothing to define where fielders had to positions themselves.
