BOSTON — J.J. Redick scored 28 points, including four free throws in the final 65 seconds, to help second-ranked Duke hold off No. 15 Boston College 83-81 on Wednesday night.

Duke (20-1, 8-0 Atlantic Coast Conference) led by as many as 18 early in the second half before BC (16-5, 4-4) whittled the lead to six. The Eagles made it a one-possession game in the final seconds without star Craig Smith, who fouled out with three minutes left.

But Shelden Williams stopped Tyrese Rice on a coast-to-coast drive — sending him to the floor hard without drawing a foul. Williams, who finished with seven blocks, was fouled and made both free throws with 7.4 seconds left.

Williams had 21 points — including 13-of-16 from the line. Josh McRoberts scored 14 and Sean Dockery had 12 for Duke, which has won three straight since its only loss, at Georgetown on Jan. 21.

Jared Dudley had a season-high 28 points for Boston College, which had won four straight games in the ACC since opening its first season in the conference 0-3. The Eagles fell to 0-4 this year against ranked opponents.

Smith finished with eight points and eight rebounds, going scoreless in the second half before fouling out. It's the second consecutive game the preseason All-America selection — the first in school history — has been held under double-digit scoring.

The move to the ACC was supposed to raise the profile of college basketball in Boston, where the appetite for the pros relegates college sports to quaint little diversions like the Beanpot hockey tournament and the Head of the Charles regatta.

But even as it rose to No. 6 in The Associated Press Top 25, BC still had trouble drawing attention away from the New England Patriots' playoff run and the Red Sox front office mayhem.

On Wednesday night, it was the pros' turn to watch.

At the game from the Patriots: owner Bob Kraft, coach Bill Belichick and quarterback Doug Flutie. From the Red Sox: president Larry Lucchino and other members of the front office. From golf: Brad Faxon and executives from the Deutsche Bank Championship. From television, NBC correspondent Tim Russert.

The star-studded crowd — in a sea of free yellow T-shirts that tried to make the Conte Forum more like Duke's Cameron Indoor Stadium — saw BC jump take an early advantage and nurse it through seven lead changes in the first 13 minutes. Trailing 25-21, Duke scored 16 of the next 21 points to take the lead for good.

The Blue Devils finished the first half up 44-34, with nine of their 12 points with the fast break, layups or dunks. They made it a 12-point game on Williams' two free throws to start the second before Dudley made two straight baskets to bring BC within eight.

Then the Blue Devils showed they can be devastating from the outside as well.

Redick hit a 3-pointer. Dockery hit a 3-pointer. Redick hit another 3, and over a 57-second span Duke had turned an eight-point game to a 17-point game, 55-38 with 17:34 left to play.

Duke led 61-43 with 12:47 left when BC went on a 14-2 run to make it a six-point game. But McLain missed a pair of free throws with a chance to cut it to four.

Rice hit a 3-pointer from the right side — his first basket of the game — to make it 71-67 with 3:19 left. But Smith drew his fifth foul on the next possession, joining Sean Marshall on the bench.

Greg Paulus made one of two free throws, then McLain scored on a foul-line jumper to make it a three-point game. BC was fouling on every trip down and Redick — a 92.1 percent free throw shooter coming into the game — missed one of two. He finished 9-for-10 from the line for the game.

But with a chance to come as close as one point, Williams stole an entry pass and Redick made a pair of free throws.
