You can view venue usage sorted by venue, date, and time. This is particularly useful if you are trying to find open slots to schedule. Go to View Venue Usage, define the date range, and choose a venue. You can also view all games that have not had venues assigned by clicking on Venue To Be Determined.

Note that games of other leagues on the same field will be displayed as well, if the other league is "sharing" the venue with your league. Also, games on other venues that have a "sub-venue" relationship (in either direction) will also be shown.
