The Devils also upped their mark as the nation's top ranked program to 23-1 while adding a tenth straight loss to the Tar Heels' slate against Duke.
After finishing the first half with a seemingly comfortable 38-27 halftime advantage, Duke quickly found itself in a battle after Latta sparked a 21-10 North Carolina run to open the second half and tie the game with 10:17 remaining.
The teams traded baskets for the next four minutes before Beard found Lindsey Harding on the wing for a three pointer to break a 54-54 tie with 6:40 remaining in the game. Harding's shot would spark a 16-0 run that put the game out of reach.
During the run Duke turned to Bass, who scored six points thanks to inside play that earned a pair of trips to the free throw line. There she converted 3-of-4 attempts before converting a three point play to give Duke a 68-54 lead with just under three minutes remaining.
Duke, which is ranked #1 in the Associated Press Poll and second in the coaches' poll, returns to action next Sunday at Virginia.
