The Lady Cardinals were plagued by a slow start, falling behind 11-5 at the end of the first quarter.
A 7-0 run to start the 2nd quarter pushed Chadron ahead 12-11, but the Red Raiders responded with a 13-5 run into the half for a 24-17 lead at the break.
Chadron was able to cut the deficit to six to start the third quarter, but again Sidney responded to push the lead to ten, 36-26, heading to the fourth quarter.
Sidney went 20 of 31 at the charity stripe while Chadron went just 8 of 13.
