It was supposed to be Seth Curry's homecoming -- then Ryan Kelly stole the show.
Kelly scored 18 points to help top-ranked Duke remain unbeaten with a 67-50 victory over Davidson on Wednesday night.
Quinn Cook scored 15 points and Mason Plumlee scored eight of his 10 in the second half for the Blue Devils (13-0), who are one of only four undefeated teams remaining in Division I.
The game was tied 29-all at halftime before Duke opened the second half with a 12-0 run. The Blue Devils, who led by as many as 19 in the second half, heated up from 3-point range after the break, going 3 for 4 in the early minutes of the period.
Curry, playing in front of his hometown fans and against his older brother Stephen's alma mater, had a rough night, finishing with six points on 3-of-11 shooting. Earlier in the day, Stephen Curry, who plays for the Golden State Warriors, wrote on Twitter that he was rooting for Davidson but hoping his brother dropped 30-plus points.
That didn't happen, but Kelly picked up the slack, hitting 5 of 8 from the field, including 3 for 4 from 3-point range.
Jake Cohen led Davidson (7-6) with 19 points and eight rebounds despite battling through early foul trouble, and De'Mon Brooks pulled down 12 rebounds and scored eight points in the Wildcats' 24th straight loss to Duke.
This was the final tuneup for both teams before opening conference play Saturday night. Duke hosts Wake Forest in ACC action, while Davidson kicks off Southern Conference play at home against UNC-Greensboro.
Plumlee scored on an inbound play to ignite Duke's 12-0 burst coming out of halftime.
After a pair of free throws by Kelly, Quinn Cook hit a foul-line jumper and Tyler Thornton knocked down a 3-pointer from the wing. Kelly capped the run with a 3-pointer from the left corner, his third of the game, to push the lead to 12.
Davidson, which hung tough in the opening half, would never get closer than eight after that.
The Wildcats entered the locker room at halftime tied despite shooting just 32 percent in the first half. Cohen, last year's co-conference player of the year along with Brooks, sat out 15 minutes after picking up his second foul less than three minutes in.
Davidson did it with hustle, outrebounding the taller Blue Devils 22-15 in the opening half, including a 9-1 edge on the offensive boards.
The Blue Devils' largest lead of the first half was five after Kelly sank the second of a pair of 3-pointers to put Duke up 29-24. But the Wildcats closed the half with five straight points. Plumlee, who came in leading Duke at 19.5 points per game, was a non-factor in the first half with only one field goal.
That all changed in the second half as Duke began to assert itself inside and heated up from outside with strong ball movement.
Brooks, who has been a factor inside for the Wildcats all season, struggled to get off shots against Duke's defenders, who began collapsing on him in the paint. Brooks finished just 4 of 13 from the field.
Duke held Davidson to 30 percent shooting for the game, and the Wildcats were just 4 of 19 from behind the arc.
