Fielder → It is formed from "field" (from Old English *feld*, meaning an open land or area) and "-er" (meaning a person who). A fielder is a person who plays in the field, particularly in sports like baseball or cricket.
Think of someone who is a person ('-er') in an open area ('field') — that's why a fielder is someone who plays in the field.
