AURORA -- Unwana Ekiko made a layup just as time expired as Smoky Hill, a No. 7 seed, knocked off No. 2 Regis Jesuit at the buzzer 47-46.

Ekiko finished with 10 points. Trent Clay had 15, while Williams had 14.
Bryan Staerkel had 16 points for Regis Jesuit, and Kip Boryla added 15 to go with nine rebounds.
