loser of tonight's UCLA-Texas Tech game crosses over to the other side of the bracket with the winner of the Oklahoma-Texas game going on right now. These are the highest ranked teams remaining in the WCWS iirc, the Sooners the four or fie time defending champions. Chances of winning are reduced if you have to get past Oklahoma just to make the finals.
Easiest and best path is clearly to win tonight - than we'll see how it all develops
