DURHAM, N.C. (Interstat) — In a classic Atlantic Coast Conference battle defined by defense and dramatic swings, the Duke Blue Devils edged the North Carolina Tar Heels 72-68 in a women’s basketball showdown Sunday at a raucous Cameron Indoor Stadium.

The game, played before 9,314 fans, lived up to its storied rivalry billing, featuring 10 lead changes and five ties. Duke improved to 19-6 overall, while North Carolina fell to 21-6.

The most critical sequence unfolded in the final 15 seconds. Trailing 71-68, North Carolina’s Elina Aarnisalo saw her driving layup attempt emphatically blocked by Duke’s Taina Mair with 21 seconds left. The Tar Heels retained possession, and Nyla Brooks sank a clutch 3-pointer from the wing with 15 seconds remaining, slicing Duke’s lead to 71-71 and sending the visiting contingent into a frenzy.

Duke immediately called timeout. On the ensuing inbounds play, North Carolina’ Indya Nivar was called for a foul on Ashlon Jackson, sending the Blue Devils guard to the line for two shots with eight seconds on the clock. Jackson missed the first free throw but calmly sank the second, putting Duke ahead 72-71.

North Carolina used its final timeout to advance the ball. On the inbound, Aarnisalo’s rushed 3-point attempt from the top of the key missed, and Duke’s Toby Fournier secured the defensive rebound. She was fouled but missed both free throws, giving North Carolina one last desperate chance with two seconds left. However, a held ball on the rebound was awarded to Duke, sealing the victory.

The game’s momentum shifted decisively in the second quarter. After a tightly contested first period that ended with Duke leading 19-18, the Blue Devils unleashed a 22-15 second-quarter run to take a 41-33 halftime advantage. Duke’s defense tightened, forcing eight Tar Heel turnovers in the quarter, while their offense found a rhythm from deep. Jordan Wood hit two critical 3-pointers in the final 1:32 of the half, including a buzzer-beater assisted by Mair to cap the surge.

North Carolina refused to wilt, responding with a 21-17 third quarter to claw back within four points. The Tar Heels’ interior duo of Ciera Toomey and Nyla Harris worked effectively, and Indya Nivar heated up, hitting a 3-pointer and a driving layup in the final minute to keep the pressure on Duke.

The fourth quarter became a tense, possession-by-possession grind. North Carolina drew within a single point on multiple occasions but could never regain the lead. Key plays from Mair, including a driving layup with 2:19 left and the game-sealing block, proved the difference.

Duke was led by a stellar all-around performance from junior guard Taina Mair of Boston. She finished with 14 points, seven rebounds, seven assists, one block and two steals in 37 minutes, directing the offense and making pivotal defensive plays. Ashlon Jackson of China, Texas, matched Mair’s 14 points and added five rebounds and four assists. Riley Nelson of Clarksburg, Maryland, contributed 13 points. Toby Fournier of Toronto anchored the paint with 12 rebounds and three blocks.

North Carolina was paced by 14 points and six rebounds from Ciera Toomey of Dunmore, Pennsylvania. Indya Nivar of Apex, North Carolina, added 12 points, six rebounds and three assists. Nyla Harris of Orlando, Florida, just missed a double-double with 10 points and nine rebounds, while Taissa Queiroz of Belo Horizonte, Brazil, provided eight points and seven rebounds off the bench.

Duke’s victory snapped a three-game winning streak for North Carolina and avenged an earlier season loss to the Tar Heels. According to Interstat’s ELO system, Duke entered the game with a 77.30 percent probability to win.

Both teams continue ACC play Thursday. Duke will host North Carolina State, while North Carolina travels to face Virginia Tech. The rivals will meet again in the regular-season finale on March 1 in Chapel Hill.
