DURHAM, N.C. — Marvin Bagley III exploded in the second half and No. 5 Duke pulled away to beat No. 9 North Carolina 74-64 on Saturday on Senior Night at Cameron Indoor Stadium.
Bagley III had 18 of his 21 points in the second half and shot 9 of 14 overall from the field to lead the way for the home side which trailed by as many as 13 points in the second half before rallying down the stretch.
The freshman sensation, who was playing his third game since returning from a knee injury, completed his double-double with 15 rebounds, including 11 in the second half.
Grayson Allen, playing in the final home game of his career, added 15 points with five rebounds, five assists and five steals for Duke, which shot 60 percent in the second half and made eight 3-pointers after halftime.
The senior captain played all 40 minutes of the contest.
Gary Trent Jr. supported with 13 points, but shot just 5 of 16 from the floor. The freshman also grabbed five rebounds for the Blue Devils (25-6, 13-5 Atlantic Coast Conference) to clinch the No. 2 seed in the ACC Tournament.
Cameron Johnson led North Carolina with 16 points, while Kenny Williams and Luke Maye each had 13.
Williams also had eight rebounds and four assists and Maye collected seven boards for Tar Heels (22-9, 11-7) who rallied from a double-digit deficit in Chapel Hill to win the first meeting three weeks ago.
Theo Pinson finished with 12 points on 6 of 10 shooting to go with eight rebounds for UNC which shot just 37 percent from the field in the defeat.
After trailing by 10 points at halftime, Duke went wild in the second half in a 20 point turn around that completed the victory.
“I’m not going to call any plays,” Blue Devils coach Mike Krzyzewski said he told his team.
“If you hit, cut, everybody touch the ball, you see a play to make, you make the play. And get comfortable in the game. And they did that. You could see them do that.”
North Carolina head coach Roy Williams admitted: “They kicked our butts in the second half.”
Point guard Joel Berry II, who is averaging 17 points per game this season and scored 21 in the first game, was held to just six points on Saturday and went 0-7 from 3-point range as UNC was just 5 for 17 from long range after halftime.
Williams added about his team losing composure in the second half: “Aliens crawled up in my guys’ bodies in the second half, because this wasn’t the North Carolina team I’ve seen all year.”
Duke Blue Devils will play either Notre Dame, Pittsburgh or Virginia Tech on Thursday night in the conference tournament.
