From the NCAA Softball 2009 Rules and Interpretation:
2.10 Fences
It is highly recommended that the playing field be enclosed completely by
permanent home-run and sideline fences at least 6 feet high. If a temporary
home-run fence is used, it must be secured so as not to collapse on and
displace the foul pole. For an unfenced field, an out-of-bounds line shall be
used to define dead-ball areas. The distance to the home-run fence should be
a minimum of 190 feet in left and right fields, and a minimum of 200 feet
in center field. The distance to the home-run fence should be a maximum
of 225 feet in all fields.
The NCAA sets the fence distances. There is no warning track because this is played within another field with has a fence distance of 305'. That might be just a little deep for NCAA softball
It is going to be real interesting to see how ASA adjusts between the World Cup games and Battle of the Borders SP series to be played in the stadium in the middle of the World Cup games. I have a feeling some of those plans are still on the planning board.
