Not all fields are alike, like I mentioned earlier. Below is a softball field in a very small town I nominated and got approved this past summer. It’s a place I know well, as I often visited to watch the rec league team play games, and visit with others in the town. The team and the bar that sponsors the team built the backstop and field, and that backstop is quite old. It’s mainly a wooden frame, with metal fencing attached. It’s the only one in this tiny town, and is quite a social hub in the summer.
Also, this is what is noted about complexes with several fields in the Sports Fields clarification:
So, if a baseball complex has multiple fields, they usually will have a number or letter assigned to them, or even have their own names that come from sponsorships or dedications. Take this ball field complex as an example: all fields have a number, and the baseball only fields also have names from sponsors or dedicated to those who were a part of the baseball community (Helling Field is named after former MLB playger Rick Helling, Starion Field is sponsored by Starion Financial).
