DURHAM, N.C. – Tricia Liston scored a career-high 29 points with five 3-pointers and No. 5 Duke beat Wake Forest 81-70 on Sunday after losing star Chelsea Gray to a knee injury.

Haley Peters added 13 for the Blue Devils (24-1, 14-0 Atlantic Coast Conference). After Gray went down in the first half, they had trouble putting away a Wake Forest team they beat by 29 points last month and led by 13 with 15½ minutes to go.

Chelsea Douglas scored a career-high 24 points with five 3s for the Demon Deacons (11-15, 4-10), and Lakevia Boykin tied it at 67 with a 3 with 3½ minutes left.

Elizabeth Williams hit two free throws with 3:07 left. Liston followed that with a 3 and two foul shots to make it 74-67 and put the Blue Devils on their way to their 39th straight victory in the series.
