DURHAM, North Carolina (Ticker) -- Freshman Luol Deng scored 10 of his 18 points in the first 9 1/2 minutes of the second half as third-ranked Duke got past stubborn Princeton, 69-51, to extend the nation's longest home winning streak to 32 games.
Deng, Duke's leading scorer at 14.4 points per game, registered the Blue Devils' first eight points of the second half after being held to just three in the opening 20 minutes.
Duke got a scare when Deng, who made 7-of-13 shots and grabbed a game-high eight rebounds, fell to the ground late in the game after defending a shot. He grabbed his left leg and winced in pain but after a brief delay was able to walk to the bench under his own power.
"I'm from Jersey, so I watch Princeton a lot and I just knew they were going to hold the ball a lot on offense," said Deng, who came off the bench in Duke's previous game. "I knew it was going to be a defensive game."
J.J. Redick added 17 points and Daniel Ewing contributed 15 for the Blue Devils (7-1), who posted their fourth straight win since losing to Purdue in the championship game of the Great Alaska Shootout.
Redick went 4-for-4 from the foul line, extending his streak of consecutive free throws made it 36. For his career, Reddick is shooting 93.5 percent from the line (129-of-138). Last season, he set a school record by making 43 straight foul shots.
"That's a difficult team to play," said Blue Devils coach Mike Krzyzewski, who won his 597th game at Duke. "That's why they have such a tradition of excellence over the decades. They certainly played together as a team and they're difficult to defend."
Princeton (4-3) stayed close early, pulling into a 25-25 tie on Will Venable's two foul shots with 2:42 left in the first half. But the Blue Devils took a 31-27 lead at the intermission and wore down the Tigers in the second half.
Chris Duhon's steal and coast-to-coast layup gave Duke a 51-39 advantage with 9:26 remaining. The final score represented the Blue Devils' biggest lead.
"In the first half, we let them settle down and just run what they wanted to run," Deng added. "We kind of stepped back and let them come at us. But in the second half, we were more enthusiastic and we didn't let them run their thing."
Andre Logan, who only played in seven of Princeton's previous 50 games due to an ACL injury, led the Tigers with 16 points. Mike Stephens was the only other player in double figures for Princeton with 10 points.
"I think Duke made a conscious effort in the second half to take away a few of the drives we had and a few of the cuts we had," Princeton coach John Thompson III said.
Princeton, known for its 3-point shooting, was just 2-of-18 from beyond the arc. The Tigers still managed to stay in the game until the final minutes, pulling within 55-47 on Scott Greenman's layup with 5:57 to go.
"We are a 3-point shooting team," Thompson added. "We usually shoot better than we did tonight and that was because of (Duke's) terrific defense. We have guys that missed tonight who are very good 3-point shooters."
