ATLANTA (Ticker) -- J.J. Redick was able to outshine Chris Bosh in a duel of the top two freshmen in the Atlantic Coast Conference.
Redick scored 13 of his 19 points in the first half to lead fifth-ranked Duke to its fourth straight victory, 77-58 over Georgia Tech.
Redick was 6-of-7 from beyond the arc as Duke shot a sizzling 65 percent (11-of-17) on 3-pointers. His six 3-pointers and six assists were season highs.
"I think his assists made his 3-pointers even better," Duke coach Mike Krzyzewski said. "He was just a really good player tonight and that's something that he should be - we should be able to play off his 3-point shooting."
Dahntay Jones added 17 points and threw home a pair of thunderous dunks in the first half to ignite Duke (20-4, 10-4 ACC), which beat Georgia Tech for the 14th straight time. The Blue Devils also notched their seventh consecutive 20-win season.
One of Jones' dunks spearheaded eight straight points by Duke for a 22-13 advantage with 6:27 left before halftime. Redick had a pair of 3-pointers and Jones added another jam in a 10-0 surge that supplied a 33-19 cushion with 3:32 remaining.
"We are playing really well on the defensive end of the court and it put us in a position where we got that lead and we were really difficult to come back on because we weren't giving up points very easy," Krzyzewski said.
Bosh picked up two fouls in the first four minutes - the second time that happened in as many meetings with Duke. The 6-11 center was limited to four points in the first half and was a non-factor on defense.
Georgia Tech (12-12, 5-8) suffered its second straight home loss after a 13-game home winning streak. Ed Nelson led the Yellow Jackets with a career-high 22 points.
Nelson made 3-of-6 shots to start the game, but his teammates combined to miss their first 12. Georgia Tech shot 32 percent (9-of-28) in the first half, digging too big a hole from which to recover.
"We're struggling with confidence, but we've just got to stay with them," Georgia Tech coach Paul Hewitt said. "They're doing the work we ask them to do in terms of getting up shots. Confidence is a funny thing. You lose some close games early and all of a sudden you might start to second-guess yourself."
Jones drilled a 3-pointer just before halftime to open a 41-26 cushion for the Blue Devils. Casey Sanders and freshman Shelden Williams started the second half with dunks to extend it to a 19-point bulge.
A layup by Nelson cut the Yellow Jackets' deficit to 53-40 with just over 12 minutes remaining. Daniel Ewing drilled a pair of 3-pointers around two free throws by Tech's Isma'il Muhammad for a 59-42 advantage.
"We had connecting plays where somebody drove and kicked out, which is why we had such a good percentage from 3-point range," Krzyzewski said. "Off of penetrate, dish, relocation - where our shooters had their feet set."
Ewing was perfect from beyond the arc on three attempts and scored 13 points off the bench. Williams continued his surge with 10 points and 10 rebounds, his third double-double in the last five games.
"One of the things you have to do when you play against a Duke team is defend the three," Hewitt said. "They came in and shot the ball extremely well. Through good ball movement, they got good looks and they knocked them down."
Bosh finished with 11 points, but Georgia Tech's three-guard lineup struggled mightily. Marvin Lewis, B.J. Elder and freshman Jarrett Jack combined to make just 7-of-24 shots for 17 points.
Duke shot 56 percent (30-of-54) and held a 35-31 edge on the glass. Jones grabbed eight boards as the Blue Devils took advantage of Bosh's prolonged absence.
The win moved Duke into a second-place tie in the ACC with Maryland, one-half game behind Wake Forest.
