DURHAM, North Carolina (Ticker) -- J.J. Redick was dialed in from the line while Princeton could not find its range from the arc.
Redick was perfect on 14 free throw attempts and scored 21 points to lead No. 5 Duke to a 59-46 victory over Princeton.
The Tigers got the pace they wanted, but it did not translate to success. Princeton came into the game having taken 269 shots from the arc in 12 games but hit only 1-of-17 3-pointers in this one.
"We knew coming in they were a good 3-point shooting team and our main focus was to take that away," Redick said. "We were not sharp on offense tonight. Fortunately our defense carried us through."
Behind 11 points from Redick, Duke (10-0) took a 33-18 lead at the break. The Blue Devils built their lead thanks to a 23-9 rebounding advantage and 12 second-chance points.
"Any time you beat Princeton, you have to be pleased about it," Duke coach Mike Krzyzewski said. "They're a good basketball team and they hung in there. They make it difficult and they don't give up on plays."
Princeton (8-5) pulled within eight in the second half but could not string together enough offense to overtake Duke. Will Venable scored 21 points and Judson Wallace had 12 for the Tigers.
Venable and Wallace combined to shoot 14-of-29 from the floor but the rest of the Tigers shot just 6-for-24.
"If you want to beat Duke on its home court, you have to be perfect," Princeton coach Joe Scott said. "We played Princeton basketball and were perfect in our own ways for maybe 20 of those 40 minutes and that's nowhere near good enough for this venue, against this team."
Duke was not effective on offense as no other player scored in double figures. Daniel Ewing added nine points and Shelden Williams grabbed 14 rebounds for Duke, which was 22-for-25 from the line.
Venable took all six of Princeton's free throws, making five.
Redick now has 301 made free throws in his career and ranks as the NCAA's career leader in free throw percentage at .941. Villanova's Gary Buchanan was the previous leader at .913.
"J.J. was in a position where they were taking away his jump shot with the zone, so one of things was to have him drive," Krzyzewski said. "You're going to have to foul him then because he's too good of a player and when he goes to the line, he's going to make almost all of them. That was a key factor in the game."
