Leagues, tournaments and rentals draw on one pool of fields
A complex with four diamonds is simultaneously host to a house league that owns weeknights across the spring, a travel programme that wants weekend practice, tournaments that take over entire weekends, and private rentals that fill whatever is left. Each of these is usually scheduled by a different person, and the conflicts surface late — often when two teams arrive at the same diamond.
The structural fix is to make every claim on a field, whatever its source, draw from the same availability. League blocks are reserved first, tournaments are held as multi-day blocks, and whatever remains is genuinely sellable to rentals. The scheduling conversation then happens in advance in the calendar rather than in the parking lot on a Saturday.
