Where were you playing this particular tournament ? We play indoor ball here in Indiana and we have the same problem with room. We give a LOT of consideration for the make-up of the building, field, dugout location, fire exits and other items. We try and remind the coaches that these games while being played for serious training are exactly that...training oppurtunities. We do not give advantages to the offense or defense due to unnatural configurations (building, saftey exits, fire alarms, ect.) To call a batter out in this particular stitch I would have to see some very deliberate act of interference by the batter. No diferent than outside. We have plenty of room around plate for this to happen and some of these batters are smart enought to know what they can and cannot get away with (and so are the coaches). Go to this address and clic on the "tour" to see our indoor facitily.
