CLEMSON, S.C. — Tricia Liston scored 16 points and Elizabeth Williams added 14 to help No. 5 Duke remain perfect in Atlantic Coast Conference play with a 81-37 victory over Clemson on Friday night.

The Blue Devils (17-2, 8-0 ACC) came in to Littlejohn Coliseum off an 80-72 win over No. 8 Maryland last Monday and didn't miss a beat against the Tigers (5-13, 1-6), pulling away to their 11th consecutive win this season.

Duke, which has 15 straight victories over Clemson, used a 15-2 run the last five minutes of the opening half to gain control and continued the surge after the break. It was the eighth straight game they've defeated Clemson by 24 points or more.

Quinyotta Pettaway had 12 points to lead the Tigers, who scored just 13 points in the second half.
