ATLANTA (Ticker) -- In a contest that featured some very poor shooting, Lee Melchionni hit the big 3-pointers for Duke.
Melchionni hit two key shots from the arc in the final minutes and J.J. Redick scored 21 points as No. 10 Duke overcame an inspired effort by Georgia Tech to post a 60-56 Atlantic Coast Conference victory.
Looking to keep their NCAA Tournament chances alive, the Yellow Jackets (15-9, 6-7 ACC) overcame an early deficit and the struggles of guard B.J. Elder to tie the score at 49-49 on a layup by Jarrett Jack with 3:43 to play.
With Georgia Tech's defense focused on Redick, the conference's leading scorer at 23 per game, Melchionni hit an open 3-pointer from the right wing for a 52-49 lead with 3:21 remaining and added another from the top of the arc nearly two minutes later that provided a 57-52 cushion.
Melchionni finished 3-of-7 from the arc with nine points and Shelden Williams added 12 points and 10 rebounds despite some first-half struggles for Duke (20-4, 10-4), which beat Georgia Tech for the 18th time in the last 19 meetings despite committing 19 turnovers.
Redick, who scored 16 points in the first half, was held in check by the Yellow Jackets' extra pressure in the second, shooting just 1-of-5 for five points. With the contest still in doubt, the junior guard couldn't get a shot over the final 5 1/2 minutes.
The Blue Devils, who entered the contest averaging 84 points on the road, shot 33 percent (19-of-57). After shooting just 29 percent in the second half, the Yellow Jackets finished at 42 percent (24-of-57).
Both teams also struggled with holding onto the ball, committing 19 turnovers each. Georgia Tech scored 15 points off Duke's giveaways, while the Blue Devils managed just 12.
Jack scored 20 points and Luke Schenscher added 16 for the Yellow Jackets, who went 0-of-5 from 3-point range.
In his fourth game back from a hamstring injury, Elder went 1-of-8 from the field for just two points for Georgia Tech. He had averaged 13.7 points in his previous three contests.
Redick, who was coming off a career-high 38 points in a 102-92 win over Wake Forest on Sunday, started the game by making his first three shots, highlighting an early 15-3 run with a deep 3-pointer. Melchionni added a shot from the arc on the next possession to cap the spurt, giving Duke a 20-11 lead with 11:45 remaining.
Jack brought the Yellow Jackets back, making five straight baskets for his team in a 2:25 span to tie the score at 21-21 with 7:53 to play.
