A square wouldn't really work since the cut out area is an arc. The bases are square though:) This is something that I have been thinking about doing for a while... I was more thinking of making a softball field since they are smaller than a baseball field. As randy says.. there doesn't seem to be much interest in sports sets.

Do you need this in a hurry? I'll be busy with family things for the next couple of days, but it shouldn't take too long to put one together.
