DURHAM, N.C. — Tricia Liston scored 16 of her 23 points during the decisive first-half run in No. 5 Duke's 96-56 rout of No. 22 North Carolina on Monday night.

Richa Jackson added 17 points for the Blue Devils (19-3, 10-0 Atlantic Coast Conference). They shot 54 percent and led by 41 in claiming their third straight win over their fiercest rivals — and their most lopsided since a 101-58 romp in 2000.

Chelsea Gray finished with 15 points and Elizabeth Williams had 13 points and 10 rebounds for Duke, which outscored North Carolina 39-12 during a 10½ minute stretch late in the first half. Liston hit three of the Blue Devils' seven 3-pointers during that run.

Chay Shegog had 19 points to lead the Tar Heels (17-6, 7-3). They managed just four field goals over the last 13 minutes of the half and had their five-game winning streak snapped.
