I think it is probably going to be closer to 3 p.m. before this game begins. The rain is supposed to move through Omaha by around 1:45 p.m. and the tarp must be off the field for 65 minutes before the game begins, based on what I was told a little while ago.
TDA, like Baum, is laid out northwest to southeast. A northwest wind would be blowing straight out to center, which should help the ball out to all fields.
