GREENSBORO, North Carolina (Ticker) -- After a difficult first half, Duke earned its revenge against Georgia Tech.
Shelden Williams scored 20 points and freshman Luol Deng added 19 as the fourth-ranked Blue Devils took care of the Yellow Jackets to advance to another Atlantic Coast Conference tournament championship with an 85-71 triumph.
Duke (27-4) had its 41-game home winning streak snapped last week by Georgia Tech. The game featured a first-half tirade by coach Mike Krzyzewski, who changed shirts at halftime in an effort to fire up his team.
Krzyzewski picked up another technical foul on Saturday and Duke went to the locker room facing a 36-34 deficit before a sizzling shooting performance lifted it into its sixth straight championship.
"We just felt like they just out-toughed us in Durham," Duke guard Chris Duhon said. "They got every loose ball, every rebound. We didn't fight. Today we made it a point to go out and fight those guys."
The Blue Devils, who will face Maryland in the title game, have won 17 straight ACC tournament games.
Williams also grabbed 18 rebounds as Duke held a 37-31 edge on the glass. Williams was limited to 21 minutes due to fouls in the Blue Devils' loss 10 days ago.
"Shelden was sensational," Krzyzewski said. "It was incredibly physical in the low post, as physical as I have seen it all year. Shelden handled it with great poise and he was a real force for us."
Deng also had a rough game the last time, misfiring on 1-of-14 shots. He bounced back to make 7-of-13 shots and helped Duke to a 46-32 advantage in points in the paint.
Deng's three-point play with 13:14 remaining finished an 8-0 burst that gave Duke the lead for good at 54-46. After Marvin Lewis answered with a basket for Georgia Tech (23-9), Deng's layup started a string of seven straight points and the Blue Devils maintained a double-digit advantage thereafter.
The Blue Devils built an early 21-12 lead on Shavlik Randolph's two free throws past the midpoint of the first half. The Yellow Jackets roared right back with a 10-1 run and limited Duke to two baskets over the final 10 minutes of the half.
Duke turned things around with 59 percent (17-of-29) shooting after halftime and also converted 16-of-24 from the line in the second half. Georgia Tech simply failed to keep up.
"We stopped them and contested their first shot well , but we didn't do a good job of getting rebounds," Georgia Tech coach Paul Hewitt said. "The reason for that is that we allowed them to drive to the middle and we started helping that open up the middle. They beat us off the dribble too many times during that run."
B.J. Elder scored 25 points and reserve Isma'il Muhammad added 11 for Georgia Tech. But Jarrett Jack - the hero of Friday's quarterfinal win over North Carolina - was held in check by Duhon and finished with eight points and four assists.
