This week's South Dakota Prep Media Basketball Poll features a shakeup in the Class AA boys rankings after two days of play.

O'Gorman opened the season as the preseason favorite in Class AA boys. After a loss to rival Roosevelt and two-point victory over Watertown, the Knights have fallen from first to fifth in this week's poll. Yankton takes over the top spot with Brandon Valley and Roosevelt right behind.

Class AA girls have one chance in the poll for this week. Harrisburg has moved into fifth following a 59-41 win over Pierre. Lincoln and O'Gorman continue to be the top two favorites in the class.
