I think if Decatur wins next week, they go to the State Tournament as part of the final four. I really don't remember that happening before. (They will play Cooper who won over Andrews, 4-1, 1-2, 5-3). And I thought "Cooper" meant "Abilene Cooper" but I think that's wrong. There's a Cooper out in East Texas, and I think that's the opponent.
Edit: Or, as an astute commenter pointed out, it could be Lubbock Cooper. (The Denton Record Chronicle has they story of Decatur's win here.)
