Erlana Larkins had 17 points and 12 rebounds to lead No. 2 North Carolina to a 70-57 victory over No. 4 Tennessee on Sunday night.
Ivory Latta had 12 points and Camille Little added 11 for the Tar Heels (8-0), who never trailed in the second half.
Candace Parker had 27 points to lead the Volunteers (6-1), who entered 3-0 against ranked teams this season but could neither keep up with the Tar Heels nor overcome a dry spell late in the first half.
After winning their first seven games by an average of 49 points, the Tar Heels treated their game against the Volunteers as their first significant test, one they passed by keeping their opponent at bay for most of the second half.
Parker's baseline layup with 18:13 remaining tied the score at 30.
But the Tar Heels scored nine straight points, and the Volunteers only once more got as close as three.
The Tar Heels started slowly but eventually dominated a sloppy first half, leading by as many as nine. They led 30-25 at the break.
The teams combined for more turnovers (31) and fouls (22) than field goals (21) in the opening 20 minutes.
