But it wasn't easy as the Tigers proved to be very game, never allowed Duke to lead by more than 12 throughout the contest and coming within striking distance for much of regulation.
Clemson may have had a chance to pull the upset, but Oliver Purnell's team missed 15-of-21 free throw attempts (29%), which proved to be the difference in the game.
With the offensive game struggling, Duke relied heavily on Redick, who scored 17 points in each half to keep the Tigers at bay. Perhaps the only think the All-American didn't do, was what's he's proven to be the best of all time at: hitting free throws. In fact Redick missed a career high four free throws in 16 attempts.
With his running mate providing his usual brilliance, Williams got into the act after halftime, scoring several key buckets down the stretch to record yet another double-double – his eight of the season.
The Tigers' upset bid was led by Vernon Hamilton who hit a career best 31 points on 14-of-19 shooting from the field. He surpassed his previous career mark of 21 points, which he set in the last game against Wake Forest.
After building a seemingly comfortable 11 point cushion down the stretch, Duke watched the Tigers claw back to within five at 76-71. However, the full court pressure was broken by Redick who threw a halfcourt pass to Sean Dockery under the goal to push the lead back to seven. Clemson would never seriously challenge the rest of the way.
