Diamond DeShields scored 18 points while fellow freshman Allisha Gray scored all 12 of her points after halftime to help No. 14 North Carolina beat No. 7 Duke 64-60 on Sunday in the teams' regular-season finale.

Freshman Stephanie Mavunga had 12 points and 11 rebounds for the Tar Heels (22-8, 10-6 Atlantic Coast Conference), who clinched their first season sweep of the Blue Devils since the 2007-08 season. North Carolina ran off a 20-0 run spanning halftime to lead by 19 points, then watched Duke (25-5, 12-4) respond with a 16-0 burst and fight back to within a point before holding on down the stretch.

Mavunga came up big, scoring on a stickback after Duke got within 53-52 on Ka'lia Johnson's three-point play. She then kicked out to Gray for a 3-pointer then scored inside off a feed from DeShields that pushed the lead back to 60-52 with 2:02 left.
