How to tag an incomplete baseball field

I was adding some features to a local park when I found a baseball field without bases. It is essentially a backstop (i.e. a chain link fence) with a field. There were no bases or home plate, but appeared to have some use given the wear. (Perhaps people bring their own bases or something. I tagged it as a field for now, but I thought this may be somewhat misleading. How should I tag something like this?
