DURHAM, North Carolina (Ticker) -- No. 5 Duke showed Butler the difference between imitation and the real thing.
Dahntay Jones scored 25 points and freshman Shavlik Randolph added a season-high 24 and 10 rebounds as the Blue Devils posted an 80-60 victory over the Bulldogs, who are considered the Duke of the mid-majors.
Leading 26-20, the Blue Devils (14-2) scored the final six points of the first half and the first six of the second period to take a 38-20 advantage on a jumper by Randolph at the 18:45 mark.
"They are so well coached," Duke coach Mike Krzyzewski said. "I thought we played extremely well defensively. They missed some open threes, but they really had to work hard in order to get them."
Butler (16-3) had two wins last season against ranked foes but could find no answer for Jones and Randolph, who combined to shoot 19-of-25 from the field.
"We played really hard," Jones said. "I don't think we finished the way we're supposed to, but we still gave it a good effort," Jones said. "Shavlik played great."
Randolph, who has not scored in double digits the past three games, shot 11-of-13 from the field.
"Shav was terrific. He gave us a low post presence offensively," Krzyzewski said.
Darnell Archey scored 14 points while Brandon Miller and Joel Cornette each collected 12 for Butler.
"We came because we knew what a great challenge it was, and we weren't disappointed," Butler coach Todd Lickliter said. "It's really a terrific atmosphere here.
"I'm disappointed, we compete to win, we prepare to win. I'm not disappointed in our players. I thought they battled."
Daniel Ewing contributed 11 points and Casey Sanders added 10 for the Blue Devils, who posted their 14th straight home win against non-conference teams.
The 6-10 Randolph recorded his second career double-double in just 19 minutes off the bench. His first came against Davidson on November 25.
Ewing added seven boards and Sanders six as the Blue Devils enjoyed a 40-22 rebounding advantage.
Duke got off to a slow start, shooting just 43 percent (12-of-28) in the first half, but made up for it by sinking 64 percent (16-of-25) in the second.
With the Bulldogs trailing, 38-20, with 18 minutes to play, Archey sank three free throws followed by a 3-pointer with 17:05 left.
But Butler got no closer as Duke gradually pulled away, opening a 67-46 advantage on two free throws by Ewing with 4:30 to play.
The Bulldogs committed only 10 turnovers to Duke's 14 but shot just 38 percent (22-of-58) from the floor in its second loss in 12 non-conference games.
