The interior advantage was pleasing to head coach Gail Goestenkors who saw her team improve to 3-1 on the season.
"We did a great job getting the ball in to our post players," said Goestenkors. "That has been an emphasis for us in practice"
All totaled, seven Blue Devils reached double figures led by senior Alana Beard's 20. Aside from Beard, Jessica Foley added 14, Monique Currie 12, Lindsey Harding 11, and Vicki Krapohl 10.
The Blue Devils found themselves in an early battle thanks to the LadyJacks' defensive pressure, but a combined 22 points from Bass and Tillis helped Duke build a 16 point halftime advantage at 49-33.
Duke will face #25 Auburn in the title game tomorrow. The Tigers beat Creighton 79-72 in the other first round game.
