DURHAM, N.C. — Star freshman Cooper Flagg scored 14 of his 19 points after halftime — including a stunning coast-to-coast dunk — to help No. 4 Duke beat Pittsburgh 76-47 on Tuesday night.

Fellow rookie Kon Knueppel had 17 points and made four 3-pointers for the Blue Devils (13-2, 5-0 Atlantic Coast Conference), who won a matchup of unbeaten league teams behind another strong defensive performance.

Cameron Corhen scored 11 points to lead the Panthers (12-3, 3-1), who shot 31% and went pointless in the final eight minutes.

Takeaways

Pittsburgh: The Panthers had won five straight since a blowout loss to Mississippi State in the ACC/SEC Challenge on Dec. 4, but they trailed 34-24 at halftime and couldn’t get within single digits after halftime.

Duke: The Blue Devils have won nine straight, led by a defense that ranked third nationally on KenPom night allowing 87.4 points per 100 possessions. Duke scored the final 18 points.

Key moment

Duke led by 11 when Flagg, the 6-foot-9 Associated Press preseason All-American, stole an entry pass and broke free on the counterattack.

He pushed past Jaland Lowe, then took off from the left edge of the field and extended his right arm to stuff the ball through a foul from Guillermo Diaz Graham. This sent the “Cameron Crazies” into a frenzy. Flagg followed with the free throw and another dunk off the dribble on the ensuing possession.

Key statistics

Pitt guards Ishmael Leggett (17.8) and Jaland Lowe (17.4) had powered the offense all season but had a difficult performance. Leggett scored four points on 2-for-15 shooting while Lowe scored eight points on 3-for-12 shooting.
