The fifth seed Aberdeen Central held off a late rally from Rapid City Stevens in the 4th quarter to secure their spot in the semi-finals with a 46-43 win. Payton Burckhard scored 15, and fell one assist short of a double-double for the Golden Eagles. Brianna Kusler added 12 points and seven assist.
