WASHINGTON (Ticker) -- Shelden Williams' clutch follow shot sealed No. 5 Duke's sixth Atlantic Coast Conference title in seven years.
Williams ended a field-goal drought that spanned over 11 minutes with 3.1 seconds remaining as Duke defeated Georgia Tech, 69-64, to win its conference record-tying 15th league title.
"This has really motivated us," Williams said. "We are in position to get a No. 1 seed in the NCAA Tournament. ... We wanted to come out here and play hard against some tough ACC teams and we walked away from here with an ACC championship."
After Blue Devils forward David McClure missed his second free throw with 4.1 seconds left, Williams scored on the rebound while surrounded by three Yellow Jackets to make it a two-possession game. It was Duke's first basket since Shavlik Randolph's layup with 11:15 remaining.
In between baskets, the Blue Devils (25-5) shot 0-of-9 from the floor but converted 15 free throws, including four by Williams.
Georgia Tech (19-11), which had trailed by as many as 13 in the second half, moved within 65-64 on a hook by freshman Anthony Morrow with 24 seconds left, but a questionable foul call on Yellow Jackets guard Jarrett Jack allowed J.J. Redick to extend the lead to 67-64 with two free throws.
Williams, who was selected to the all-tournament first-team, recorded 12 of his 16 points and nine of his 13 rebounds after intermission. Over the first 20 minutes, he focused on defense, posting five of his six blocks.
"I said coming into this game that I thought he was the most important player," Georgia Tech coach Paul Hewitt said of Williams. "I think he's the guy that really allows them to do a lot of what they do offensively and defensively."
Redick, who shot 10-of-10 from the stripe, scored 26 points a day after setting the Blue Devils' tournament record with 35 in a 76-69 victory over North Carolina State in the semifinals. He was named the tournament MVP a year after the Blue Devils were knocked off by Maryland in the final.
"Today was a great moment for our team and a great moment for our guys," Redick said. "For me, it's pretty personal after what happened last year at the ACC tournament."
Redick scored 14 points on 5-of-7 shooting in the first half, including a floater with 31 seconds left that gave Duke a 34-28 lead at the break, but shot just 2-of-8 over the final 20 minutes.
"Today was a good day but it wasn't an unbelievable day for me," Redick said. "I missed my last few shots and a couple of those came up short. I guess it was a little bit of fatigue, having played 40 minutes on two straight nights."
Redick keyed a 9-0 second-half run that enabled Duke to open a 50-37 lead. After converting a driving layup from the left corner to produce a 47-37 lead, Redick dished a no-look pass to Daniel Ewing, who drained a 3-pointer from the right wing with 12:35 left to complete the run.
Ewing had 15 points and four of Duke's nine assists before fouling out with 4:32 remaining.
Jack's three-point play brought Georgia Tech within 41-37 with 15:49 remaining, but the Yellow Jackets went without a field goal over the next 8:40.
Already playing with a shoulder injury suffered in a collision with North Carolina's Sean May in Saturday's 78-75 semifinal victory, Jack landed awkwardly on his left ankle after missing a 3-pointer with 9:41 left.
"Basically they just told me it was a sprained ankle but nothing's going to keep me off the court," Jack said.
After a brief trip to the locker room, Jack returned to hit a jumper with 7:09 left to end the Yellow Jackets' field-goal drought and drained a 3-pointer 2:13 later to cap an 8-0 run that brought Georgia Tech within 56-51. He finished with 19 points.
"I'm glad he convinced me to put him back in the game because he went out and made a couple of big plays to give us a chance," Hewitt said.
Will Bynum, who scored 35 points in Saturday's win over North Carolina, scored 14 in this one on just 4-of-17 shooting. He missed two potential game-tying 3-pointers within the final 17 seconds for the Yellow Jackets, who advanced to the NCAA Tournament final against Connecticut last year.
"We can use this game as motivation hopefully if we get into the tournament," Bynum said. "The game definitely left a bitter taste in our mouth so we can just use it as motivation."
